In Warm Weather, Children Are In The Hot Seat

Monday, July 12th, 2010

Speed exercises in the summer means high temperatures and your youngsters or teens will be playing and practicing outdoors. Thus, young athletes do not adapt to hot weather like adults. Don’t underestimate the significance of the warning signs for heat illnesses and preventing them. These illnesses consist of any of the following, heat exhaustion, heat stroke and heat cramps. Whether your child or your team is doing strength training workouts as a coach, or parent,  you want to be aware of the seriousness of heat-related illnesses. In actuality, heat illness can be more dangerous to youngsters.  Heat stroke has an incredibly high death rate for children, 17-70%. The factors associated are the child’s age and the severity of the illness.

Children suffer heat-related illnesses when their bodies can not compensate for the heat and cool itself.  Youngsters are more vulnerable to heat related illnesses because they don’t adapt as fast or as well to heat changes as do adults and they also create additional warmth with activeness. Children are more at risk to heat illness since they can’t adapt as quickly or as well to changes in temperatures. In addition, they produce extra heat with activity. Young athletes perspire less than adults and they do so at a higher body temperature..  Those kids, whom are heavy, have continuing illnesses and take a number of medications are even more susceptible to high heat conditions during practice.

INDICATORS
Heat Cramps – agonizing, involuntary muscle contractions, generally in the gastrocnemius or hamstring tissues (the muscles at the back of the calves and thighs)

Dehydration – fatigue, thirst,  lightheadedness, less-frequent urination,  sloppiness, heightened heart rate and respiration, dry skin,  dry mouth and mucous membranes

Heat Exhaustion – clammy, pale skin, sweating,  tiredness (fatigue), pounding head and or vertigo

Heat Stroke – Loss of consciousness, confusion or hallucinations, headache, agitation, high body temperature, absence of sweaty, deep or shallow breathing, weak pulse rate, seizures|

PREVENTATIVE MEASURES
Be conscious that temperatures over 80 degrees produce conditions favorable to heat sickness.  It also important to know that excessive humidity reduces your body’s ability to release excess heat by perspiring. In order to prevent this illness acclimate the child to the heat, increase intensity over 10-14 days, no heavy work for the first week Have them work out in cooler parts of the day, as morning or early evening. Ensure youngsters take rest periods. Have youngsters drink fluids before working out. Make sure plenty of water is available during work outs. Whether or not they are thirsty, young athletes should hydrate every 20 min. when practicing. Liquids to keep away from are caffeine and everything carbonated. As far as clothing is concerned, children should wear lightweight and ventilated clothing.

If your teenager or your team is doing speed and agility training as a trainer or parent, you need to be aware of the gravity of heat-related sickness.  Respect the hot temperatures or there could be fatal consequences.

Training For Speed, Agility, And Strength

Sunday, May 9th, 2010

This posting will have a look at what role strength plays in your Speed and Agility Training course. Let’s look into a couple of words.

Absolute strength – the maximum amount of power that you are able to produce, your individual rep ceiling is your absolute strength

Starting Strength – a function of how many muscle fibers you are able to instantaneously tighten

Think of it in this way, if you snatch a heavy weight from the floor you may injure your back. However if you pick it up slowly this wouldn’t occur. Starting strength (in the example shown), merely measures the maximum load that you are capable of snatching off the ground without injury.

Relative strength – your strength for every lb of body weight

Reactive Strength or Plyometric Strength – details your capability to take in and use force while going from an eccentric contraction to a concentric contraction.

What exactly is the application of these definitions to your exercise plan?
The more your absolute strength, the higher your starting strength. The higher your starting strength, the quicker your acceleration, the quicker your acceleration, the higher your explosiveness or your capability to arrive at your maximum speed faster. Ask yourself, “Is my speed and agility training helping my absolute strength for those muscles that matter most in my sport?”

Relative strength is important because the more your relative strength, the greater the strength you can generate. This benefits you in a couple of ways; your nervous system is better conditioned and may also cross over into your quickness, and you’ve got less stuff to drag around. This also crosses over into speed.

A reasonable question to ask is whether your Speed and Agility Training improves your relative strength. Bear in mind while training for speed and agility your relative strength is more significant than your absolute strength. Note: you should not be worried excessively concerning bulking up because a 10% growth in LEAN body mass translates into a 30% boost in power.

Lastly, we come to reactive strength. This sort of strength plays a critical part in agility, it enables you to suddenly adjust direction and overwhelm your opponent with surprising moves. It also helps you to jump higher when running (but not a great deal from a standstill posture). It also plays a function in running speed although there’s better ways to work out for it if running speed is what you are after.

What is the take away home from this article? In order to appropriately train for speed and agility you have to incorporate strength training workouts in your regime. You should also tailor it for the sport you are involved with. There can be no shortcuts however there are efficient ways of arriving at your objectives (whatever they might be).

If this has bewildered you some you should….

Here’s a food for thought question for you.  Why do sprinters (50, 100 meter dash, basketball players, quarterbacks etc) have ripped abs without explicitly working out for them? Naturally you must understand that starting strength is different for separate muscles groups and can be trained individually. Knowing what muscles play a part in the movements most crucial in your athletic endeavour makes it possible for you to focus on them and generate fast and effective results
