What to Use to Clean the Inside of a Football Helmet

Let’s face it — sweat happens. There’s no escaping sweat and grime inside your football helmet after hours of intense practice and game-time wear. You can’t just toss your helmet in the washing machine, but a few household items can help you keep your helmet clean and free of smelly bacteria.
The foam pads inside your helmet and the plastic covering the exterior don’t hold up well under abrasive cleaning pads. Instead of grabbing the steel wool or a rough-sided sponge, stick to softer fabric cloths that won’t ruin the finish or remove the protective coating of the pads. Microfiber pads work well, but a plain cotton cleaning cloth or dish towel won’t harm the inside of the helmet either.
The outside of your helmet might get filthy as you tackle into the grass, but the inside’s main problem is sweat. Gentle cleansers work best, such as a mild dish-washing liquid or oxygen bleach solution. Use a damp rag and rub the cleanser over all the pads, getting in between them as best you can. Wipe the area with a rag dipped in plain water to remove the soap. This will prevent it from irritating your skin the next time you wear the helmet.
Bacteria from your sweat and skin cells can travel inside the pads of your helmet, so get rid of them by spraying the entire inside of the helmet with a disinfectant. Leave the helmet sitting upright on a hard surface until it’s completely dry; the spray will penetrate the pads as it dries. Keep the helmet out of extreme heat or bright sunshine as it dries, as these can degrade the pads.
While mild, non-abrasive cleansers are safe for the pads inside your helmet, many cleaners are not. Avoid using harsh chemicals such as bleach, ammonia or turpentine. Also stay away from many bathroom and kitchen cleaners, which often contain abrasive particles. If you don’t have safe cleansers on hand and you must clean your helmet, use a rag dampened with warm water and scrub gently. Clean the helmet with the proper cleansers when possible.

Frequency of Injury Among College Athletes

Two entities that compile injury statistics for the roughly 380,000 male and female college athletes. The NCAA and the National Athletic Trainers’ Association have an injury surveillance system that collects injury reports submitted by trainers. It has been in operation since 1988. Through 2004, there were 200,000 injury reports — filed when an athlete misses a day or more of practice or competition — which works out to about 12,500 injuries per year. That number has been relatively consistent over the years. The National Center for Catastrophic Sports Injury Research in North Carolina has kept statistics on college sports injuries since 1982. Both organizations aim to reduce the number of injuries in college sports.
The national surveillance system breaks injury statistics down by sport, type and year. For example, although college baseball has a relatively low rate of injuries, 25 percent of them are serious or severe, defined as injuries that prevent players from practicing or competing for at least 10 days. Sliding accounts for 13 percent of the recent injuries and the impact from a batted ball accounts for 10 percent of injuries. The trainers organization recommend break-away bases to cut down on the sliding injuries.
Concussions at all levels of football are a tremendous problem as of 2011, with a growing number of retired professional football players suffering from dementia after repeated concussions during their playing days. Among college football players, 34 percent have had one concussion and 30 percent have had two or more concussions. As the University of Pittsburgh Department of Neurological Surgery reports, if you have a second concussion, even a minor one, soon after the first concussion, you might die. A total of 26 deaths, most occurring since 2000, are attributed to “second impact syndrome.” The neurological effects of concussions in college athletes also can result in learning disabilities and severe memory impairments. There is a lower, but significant, incidence of concussions in soccer as well.
Female college athletes suffer from up to five times as many ACL — anterior cruciate ligament — injuries as male athletes. ACL injuries bedevil women basketball, soccer and softball players, among others. As an article in “The New York Times” explains, there are anatomical, biomechanical and hormonal reasons why women are so vulnerable to ACL tears. Trainers are teaching players to land and cut in ways that might cut down on the number of such injuries.
While other sports, such as ice hockey and lacrosse have spectacular body-to-body contact and collisions during play, football still has the highest injury rate with 36 injuries per 1,000 male athletes. In addition to the high number of collisions in football, it also has the highest number of knee and ankle injuries. Cheerleading is by far the most dangerous sport for women athletes. The National Center for Catastrophic Sports Injury Research found that cheerleading accounted for 70.5 percent of catastrophic injuries — fatal, disabling or serious — suffered by college athletes. The high-flying routines create unique risks for cheerleaders.

Football Soccer Tactics & Skills

Soccer players must learn fundamental skills and tactical awareness to succeed during competitive games. Important soccer skills to master include ball control, passing, dribbling, shooting and defending. Tactical awareness involves the ability to know your role and have positional awareness on the field, and possessing the ability to make good decisions.
The fundamental skills of soccer are vital to the development of a soccer player. You must have the ability to trap the ball and keep possession for your team to be effective during a competitive game. A high level of repetition is the best way to learn fundamental soccer skills. Soccer skills should be practiced initially under no defensive pressure, with the coach focusing on correct technique. For example, to practice dribbling, the coach should have players dribble a ball around a 20-yard box focusing on technique and keeping the ball under control. Passive resistance should be added by placing a number of cones down and teaching turns to avoid the obstacles. You can next pracrtice dribbling with two or three defenders inside the box attempting to win the ball, and providing game-like defensive pressure.
Tactical awareness largely refers to a soccer player having the ability to make effective decisions during a soccer game. You can practice soccer tactics by using group drills that work on skills and forcing players to make decisions quickly in game-like situations. Playing three attackers against two defenders toward the goal can be good tactical practice. The attacking team can begin each repetition 25 yards out from goal. On the coach’s signal, they begin play, attempting to score a goal with the two defenders attempting to stop them. The soccer coach can use this drill to practice teaching players when to dribble and when it is best to pass to a teammate. The decision of when to shoot should also be taught in this drill.
Players should have an understanding of their role on the field, whether it be defender, midfielder or attacker. Regardless of position, all soccer players should have the tactical awareness to get open and provide a passing option when a teammate is in possession of the ball. When defending, a soccer player must have the ability to put pressure on the ball if they are the nearest defender, or to cover an off-the-ball runner, providing defensive balance.

What Are Positive Things About Football?

Physical pain is just part of the game of football. However, as of 2013, the scariest issue was how all of those collisions impacted a player’s post-game life. The National Collegiate Athletic Association claimed there were 2.5 concussions for 1,000 contacts during college football games in 2011. Concussion talk alone led President Obama to say he wasn’t sure he’d allow a child of his to play football. Despite that talk, the game’s popularity endured because it still offered significant benefits to its participants, both on and off the field.
A good high school football player can turn that skill into a free college education. That’s an option in other sports of course, but none have as many opportunities as football. As of 2013, all Division 1 schools had 85 scholarships for football, and all of them had to be “full rides.” According to the NCAA, only 1.7 percent of college players ultimately go pro. However, the players who take advantage of those paid scholarships can set themselves up for some other career.
Although few football players ever make the pros, just being a football hero can still raise a player’s social status. In small towns, football can become the center of social life according to “Contemporary Issues in Sociology of Sport.” A 2008 study it published followed four African-American college football players. It found that participation in the sport significantly raised their social status and encouraged others to listen to them and respect their opinions.
In football, it’s routine that all 22 players have something to do on every snap. If one fails, chances are the whole play fails. That means football players have to learn how to actively strategize and communicate, a skill that can carry over to other parts of life. The simple act of a quarterback calling signals nurtures an environment where players must learn to listen to one another, according to “Football and Philosophy.”
Like other sports, football provides plenty of opportunities for exercise. Unlike some, it encourages both cardiovascular exercise such as running and jumping and strength training. Strength training is a critical component even at the high school level. The book “Survival Guide for Coaching Youth Football” also notes that the constant motion required in football means extra exercise for the players.
Even the strongest and fastest player won’t succeed if he can’t follow a team’s strategy, which can involve learning a huge number of plays and signals. He’ll also have to learn why those plays should work and how to apply them under pressure. A 2011 study published in “Social and Behavioral Sciences” specifically mentions that football can help improve spatial reasoning skills. These skills can benefit players off the field. For example, a 2010 article in “Scientific American” emphasizes the important role spatial reasoning plays in math and science achievement.

Causes, Risk Factors and Prevention of Back Pain

The most important thing to understand is that the definitive cause of an individual¡¯s back pain is difficult to identify. It has been estimated that a definite cause is evident about 20 percent of the time using tests like MRI of the lumbar (lower) spine.
There are many structures in the back that may be the cause of the pain. This includes all of the structures in and around the spine that contain nociceptors, which are tiny nerves responsible for transmitting pain. This includes the lumbar discs, the facet joint capsules, the sacroiliac joint, muscles, fascia, vertebral bodies and dura. It also includes abdominal and pelvic structures, such as the uterus, bowels, aorta, kidneys and ureter.
It is common for health care providers to search for the cause of back pain with X-rays, CT scans or MRIs. These tests can be misleading because they may reveal abnormalities that aren¡¯t necessarily causing the pain, leading to unnecessary treatments that are expensive and associated with risks.
One common example is when an MRI reveals a herniated disc in the low back, therefore the patient assumes this is the cause of his back pain. However, we now know that herniated discs seen on an MRI are often not painful. But, once this patient is aware of the herniated disc, he will tend to be more guarded in his actions and see himself in a vulnerable light. These psychological and behavioral alterations can also be a source of pain. Thus, pursuit of the diagnosis can not only be misleading, but can actually contribute to the back pain.
Because back pain is both common and recurrent, the most important risk factor by far is a previous history of back pain. Other risk factors are much less important and hard to pin down. They may include a family history of back pain, smoking and a job that involves very heavy lifting.
Despite popular belief, the following are not risk factors for back pain: being overweight, degenerative disc disease, the physical pounding of exercise and having a physical job or cumulative damage from a long physical career. It has been my observation that sitting is more destructive than most forms of lifting and carrying.
Although the words ¡°acute¡± and ¡°chronic¡± suggest that the pain is characterized by its duration, the distinction and meaning has come to signify something more nuanced.
Acute pain is when a pain is sharp for a short period of time, and then the pain goes away either with or without treatment.
Chronic pain is when the pain has been present for more than six months. Also, whatever initiated the pain has either healed or had sufficient time to heal. The reason for the persistence of the pain is difficult to pinpoint, and the role of the brain as the source of persistence is inferred.
There has been an enormous effort in the field of ergonomics to study workplace environments with the hope of modifying them (chairs and desks) to lessen back pain occurrences. In my opinion, however, the best way to reduce back pain at the workplace is not through ergonomics, it¡¯s to improve the overall job satisfaction of the workers because stress is a big contributor to back pain.

Meal Plans for Teenage Boys

Teenage boys experience rapid growth and change, requiring them to get proper nutrients from their daily diets. Teenage boys who are active in after-school activities such as sports may need additional amounts of nutrients, such as protein, to support growing muscles. Additionally, eating a healthy breakfast, adequate caloric intake and healthy snacks will give a teenage boy the energy he neese to complete daily tasks. Always consult with your child¡¯s pediatrician prior to changing his diet.
Breakfast is the most important meal of a teenage boy’s day. Eating breakfast within one hour of waking up will help supply his body with energy for the day as well as help prevent him from eating junk foods throughout the day. A healthy breakfast should consist of whole grains, protein, dairy products and fruits. An example of a healthy breakfast would be a bowl of whole grain cereal, a hard-boiled egg, low-fat yogurt and an orange or a glass of orange juice.
Eating a healthy lunch will give your teenage boy the fuel and energy to maintain performance for school work and after-school activities. Additionally, it will help hold him over until dinner time. If he carries his lunch to school, you may be able to prevent him from overeating while ensuring he eats nutritious foods. An example of a healthy lunch for your teen is a turkey sandwich on whole wheat bread, carrot and celery sticks with low-fat ranch dressing, a piece of fruit and a bottle of water or naturally sweetened fruit juice.
Your teenage boy’s dinner should be nutritious as well as filling enough to keep him full for the next 12 hours. Additionally, when possible, eating dinner at the same time each night may keep him from late-night snacking on junk food. An example of a healthy, nutritious dinner may include a 3 oz. piece of baked fish, two servings of steamed vegetables, a slice of wheat bread or a wheat roll and a bottle of water.
Frequent hunger is common during the teenage years due to your teen’s body¡¯s growth demands, says KidsHealth.org. Healthy snacks such as fruits and vegetables will help keep his energy levels high for after-school activities, sports and to hold him over until dinner. Healthy snacks include veggie sticks such as celery and carrots dipped in low-fat dressing, low-fat yogurt and bottled water.
Teenage obesity is a growing, dangerous problem, according to the 2010 Dietary Guidelines for Americans, which recommends that a boy between the ages of fourteen and eighteen should consume 2,400 to 2,800 calories if he’s moderately active. Underactive teens who do not eat a healthy and nutritional diet are at greater risk of becoming obese. Teenagers should get at least 60 minutes of physical activity each day.

Caloric Intake for Soccer Players

The average soccer player runs 5 to 6.5 miles in a typical game, much of which is at a sprint that demands the heart work at 85 percent of its maximum rate. To perform her best under these conditions, a player needs to consume adequate calories regularly and to obtain them from the right proportion of nutrient-dense foods. Ask a physician or sports nutrition expert to help you develop a personalized diet that will enhance your soccer skills.
According to Virginia Tech exercise science professor Jay Williams, a soccer player usually needs to consume 20 to 27 calories for every pound of body weight each day to replace the energy burned during practices and matches. This means that a 120-pound female player needs approximately 2,400 to 3,240 calories daily, while a 160-pound male player should have 3,200 to 4,320 calories per day. Elite soccer players may need more, while recreational, amateur players may require less.
About 60 percent to 70 percent of a soccer player’s total daily caloric intake should be supplied by carbohydrates, or roughly 4 grams of carbohydrates for every pound of a player’s body weight daily, says Williams. Other sports nutrition experts recommend around 2 to 3 grams of carbohydrates per pound. On average, a 160-pound man following Williams’ advice would need around 2,444 calories each day from carbohydrates, or 611 grams. A 120-pound woman would need approximately 1,833 calories supplied by about 458 grams of carbohydrates. These carbohydrates should come from a variety of low-fat, low-sugar sources such as whole grains, fruits, vegetables and unsweetened juices.
Soccer players should not avoid fat, but they should focus on mono- and polyunsaturated sources like seafood, nuts and nut butters, olives, avocados and vegetable oils such as olive oil while avoiding trans fats from processed foods and saturated fat from butter, full-fat dairy and red meat. Williams advises getting at least 20 percent of your daily calories from healthy fats, but Nancy Clark, co-author of the “Food Guide for Soccer,” says you should aim more toward 25 percent. A 160-pound man could have approximately 94 grams of fat daily, supplying 846 calories; a 120-pound woman could have about 70 grams of fat, which supplies 634 calories per day.
Protein should make up 10 percent of the typical soccer player’s diet, or 0.5 to 0.8 gram of protein for each pound you weigh, according to Williams and a number of other sports nutrition experts. Male players weighing 160 pounds could have around 100 to 130 grams of protein totaling 400 to 520 calories daily, while a woman weighing 120 pounds should have an average of 282 calories from about 71 grams of protein. Pick skinless poultry, lean cuts of beef or pork, fish, shellfish, beans and legumes, nuts, seeds, soy products and low- or nonfat dairy such as yogurt, milk or cheese to fulfill your requirement.

Basketball Positions & Their Roles

The development of the game of basketball has given each position on the court specific responsibilities. For many generations, each team had two guards, two forwards and a center. However, by the mid-1980s, designation of positions like point guard, shooting guard and power forward were commonplace.
The point guard is responsible for handling the ball and triggering his team’s offense. While other players will handle, dribble and pass the ball, the point guard will do the majority of that work. He will also shoot on occasion, but the point guard’s primary job is to get his teammates involved in the offense. On the defensive side, he will usually attempt to stop the opponent’s point guard by harassing his dribble and getting into the passing lanes to create steals. Former Laker great Magic Johnson was one of the best point guards in basketball history.
The ideal shooting guard is a player who can score a lot of points in a short period of time. While the shooting guard must be able to handle the ball and pass successfully, his greatest contribution is as a scorer. The shooting guard must be able to drive to the hoop and hit the outside shot as well. The greatest shooting guard in NBA history was Michael Jordan, who led the Chicago Bulls to six NBA titles.
The description of small forward usually has nothing to do with a player’s height; it has to do with a player’s ability to make plays with the ball. The small forward has to be able to dribble the ball, drive the ball to the basket and make outside shots. A small forward is often compared to a shooting guard in that they have similar jobs, but a small forward will usually help out more on rebounding and do his job closer to the rim than the shooting guard. Hall of Fame Celtics forward Larry Bird was a great all-around player who was often labeled as a small forward.
The power forward is a big and powerful individual who can dominate rebounding and inside scoring. Most of the power forward’s shots are taken from inside 12 feet and many are within just a few feet of the rim. The power forward must help his team block shots and box opponents out when going for rebounds. Former Utah Jazz star Karl Malone is one of the greatest power forwards in basketball history.
The center is almost always the biggest man on the court–a player who can alter the opponent’s offensive game by his presence, size and wingspan. These factors allow him to accomplish the tasks of blocking and changing shots. A center should also be a good scoring option when his team gets the ball near the basket. Top centers develop an array of offensive moves like the drop step and hook shot to rack up points. Players like Bill Russell, Wilt Chamberlain, Kareem Abdul-Jabbar and Shaquille O’Neal rank among the best centers in NBA history.

Which Cardio Workouts Burn the Most Calories?

Cardiovascular exercise — you know you need to do it to stay healthy and manage your weight, but you can never seem to find enough time between work, family and social obligations. The good news is you don¡¯t need to spend hours plodding away on the treadmill — you just need to choose the right workout. Activities that use more muscle mass and that involve some sort of resistance will be more taxing and burn a greater amount of calories. In addition, the higher the intensity, the more calories you¡¯ll burn. Take a look at our top 10 picks for cardiovascular exercises that give you the most bang for your buck.
Running, biking or swimming at a steady state is enough to burn some serious calories, especially if you¡¯re just starting out. But if you up your pace for periods of time during your workout and you¡¯ll increase the burn even more. ¡°Sprinting burns a massive amount of calories, but it can only be kept up for a certain amount of time,¡± explains American College of Sports Medicine spokesperson Jim White. A 155-pound person who runs at a pace of 7.5 miles per hour can burn 465 calories in 30 minutes. Try alternating between two minutes at an all-out pace (or the fastest you can sustain for that long), and then recover with one minute of jogging, White recommends.
Tabata training is a high-intensity exercise modality that burns a lot of calories in a short period of time. The protocol consists of doing 20 seconds of work at an all-out pace, followed by 10 seconds of recovery. You repeat this eight times. Almost any activity can be done in a Tabata-training style. A typical Tabata workout might include four exercises — for example, push-ups, squats, jumping rope and crunches. Although the first round might seem easy, just wait. By round eight, your muscles will be screaming! A study conducted by the American Council on Exercise determined that a typical Tabata workout can burn an average of 15 calories per minute, or 450 calories per half hour (workouts usually don’t last longer than 20 to 30 minutes).
Every muscle in your body, from the tips of your fingers to the ends of your toes, is working when you’re climbing a rock wall — whether you’re in a climbing gym or in the great outdoors. The large muscles of the back and legs are the primary movers, requiring energy in the form of calories to get you from the bottom to the top. A 155-pound person climbing for 30 minutes burns approximately 409 calories. Climbing at a good pace or on a really challenging route can increase your total burn.
Your whole body works while you’re swimming. Your legs kick, your arms stroke, your core contracts to keep you afloat. With that much muscle recruitment, it ranks as one of the top calorie-burning cardio exercises you can do. But your stroke choice can make a difference. A 155-pound person burns 372 calories in 30 minutes doing the breast stroke — an impressive number. But that same person doing the butterfly for 30 minutes will burn 409 calories. Where you swim makes a difference too. ¡°Swimming in the ocean where you’re going against the current — that would be a really, really intense workout,¡± says ACSM spokesperson Jim White.
Whether you’re biking or running, throw some resistance in the mix to significantly boost your calorie burn. ¡°Running up a steep hill recruits more muscle fibers,¡± says ACSM spokesperson Jim White. ¡°It’s going to be taxing, and it’s going to definitely burn more calories.¡± In fact, you’ll burn about 10 percent more calories for each degree of incline versus running on a flat surface. That means a 155-pound person running at a five-mph pace will burn 373 calories every half hour at a five-percent grade versus 298 calories at the same speed on a flat surface. Get those glutes firing even more and up your calorie burn at the same time by incorporating more hills into your workout.
You already know running is hard, which might be why you¡¯ve been avoiding it. But, barring any physical limitations like illness or injury, you should definitely make friends with running, because it¡¯s a top calorie burner. ¡°Because you’re moving your body over the ground, running typically has higher rate of caloric expenditure than a lot of other exercises,¡± says Andy Doyle, Ph.D., associate professor of exercise science at Georgia State University. Running at a steady pace of six miles per hour, a 155-pound person can burn 372 calories in 30 minutes. The faster you run, the more calories you’ll burn.
Although it may have seemed effortless as a kid, jumping rope is a highly taxing activity that most people can’t sustain for more than a few minutes at a time. It’s one of ACSM spokesperson Jim White’s top picks for big-time calorie burners. ¡°When you’re jumping like that, it’s almost like full sprinting,¡± he says. A 155-pound person can burn 372 calories in 30 minutes. But, because it’s hard to do for an extended period of time, White recommends doing it in intervals, where you jump rope vigorously for a few minutes and then recover by jogging in place for a minute or two.
¡°Rowing is one of the biggest calorie burners,¡± says ACSM spokesperson Jim White. ¡°You’re using your legs, which is a huge muscle; you’re using your shoulders, your back. It’s continuous; it’s one of the chart toppers.¡± In fact, rowing uses nine major muscle groups, including the hamstrings, quads, glutes, core, lats, shoulders, back, triceps and biceps. Of course, it all depends on the intensity at which you row and the conditions. Rowing inside on an ergometer, where conditions are controlled, may be less challenging than rowing on a lake on a windy day. A 155-pound person rowing on an ergometer at a vigorous pace can burn about 316 calories per 30 minutes.
Cross-country skiing is a winner on professor Andy Doyle’s list of top calorie-burning exercises. He explains that like running, you’re moving your body over the ground when you’re cross-country skiing, which automatically makes it intense. ¡°But now you’re using your arms — poling — as well as your legs with the skis. If you look at doing that going uphill versus on the flat, then that increases the rate of energy expenditure even further.¡± A person who weighs 155 pounds can burn 298 calories cross-country skiing for 30 minutes.
If you don’t know what burpees are, first, be thankful. But to clarify: A burpee is a full-body exercise that entails squatting down, kicking your feet out into a push-up position, doing a push-up, jumping your feet back to your hands, then jumping up into the air and reaching your hands over head. Just doing one or two is no big deal, but doing them continuously for a period of time gives you one serious calorie-burning workout. Although difficult to quantify in terms of calorie burn because of all the variables, burpees involve all the ingredients for major calorie burn: full-body muscle recruitment, resistance and intensity. A 155-pound person can burn 298 calories per half hour doing vigorous calisthenics, similar to burpees, for 30 minutes. Do them continuously, if you can, or break them up into intervals interspersed with another activity such as jogging or jumping rope.
¡°If you’re short on time, your best bang for the buck is to go at as hard an intensity as you can for whatever time period you have,¡± says professor Andy Doyle. Use a heart-rate monitor,fitness tracker or an app like Livestrong.com’s MyPlate to get a more accurate estimate of calories burned. Even if you’re limited to walking because of a medical condition or injury, walk as fast as you can or walk up hills, and you’re going to burn more calories than if you stroll at an easy pace. Push yourself to your limit, and you’ll reap the rewards of a fitter, leaner body.

How to Fix a Leak in a Basketball

Basketballs go through plenty of wear-and-tear during games and practices, not to mention just shooting hoops in the driveway. As such, it should come as no surprise when your ball begins to leak. If you enjoy fixing things yourself, can’t afford to replace the ball or if the ball has some special value, you may choose to repair rather than replace it. It doesn’t matter if ball itself springs a leak or if the valve is leaking — either way, you can fix it.
Submerge the basketball in a tub of water and rotate it, watching for exiting air bubbles to indicate the source of your leak.
Dry the area off and mark the leak with pencil or tape.
Heat the tip of an old, dull knife by holding it over an open flame, moving it back and forth.
Swipe the hot knife across the leak on the basketball until the vinyl begins to melt.
Allow the vinyl to cool and solidify for at least 5 minutes.
Push the inflator needle into the ball’s valve hole, then re-inflate the ball gently by using a hand pump. Fill the ball to its recommended pressure setting and do not over-inflate.
Insert a wet inflating needle into the valve hole several times to clean dirt from the valve.
Insert a toothpick into the valve hole if the leak persists.
Break off the end of the toothpick, leaving the valve plugged.
Purchase a ball repair sealant with a syringe.
Fill the syringe with the sealant according to the manufacturer’s directions.
Insert the syringe into the ball’s valve hole.
Depress the plunger on the syringe, then bounce ball vigorously.
