Easiest Way To Shave .1 Seconds Off Your 40 Time! Improve Speed In Any Sport: Get Enough Sleep.
August 13th, 2010
Many athletes would do anything to shave a tenth of a second off their personal best. The solution could be as simple as consistently getting enough sleep. Researchers are finding that getting more sleep can result in improvements in speed, concentration, alertness, and vigor. For example, in a research abstract published June 8th, 2010 it was reported that Stanford University football players shaved an average of .10 seconds off of their 20 yard shuttle and 40 yard dash sprint times after increasing their daily sleep quantity to 10 hours for a period of 7-8 weeks. In earlier studies using Stanford University intercollegiate athletes, lead researcher Cheri Mah reported similar improvements for tennis players, basketball players, and swimmers. These athletes increased their nightly sleep to 10 hours for 6-7 weeks. The sprint times and hitting accuracy of the tennis players improved, and swimmers swam faster and reacted quicker off the blocks. In addition to objective physical performance improvements, athletes in all Mah’s studies reported improved mood and energy levels. It can be a tough sell to young people that they need large quantities of sleep, but for some, it may be motivating to know that getting enough sleep could be the difference maker for that college scholarship or professional contract.
Natural Performance Enhancement Mechanisms During Deep Sleep
A number of normal processes that occur during sleep are enhanced by getting the optimal amount of sleep. Human growth hormone (HGH) is secreted during long, continuous sleep, and stimulates muscle repair and growth, fat burning, and bone growth. Want to raise HGH levels legally? Get enough sleep. Researchers have also found that the learning of new skills, both cognitive and motor, is cemented during deep sleep.
Why Sleep Deprivation is So Harmful to Performance
Sleep deprivation has been demonstrated in research studies to slow down the release of HGH. Sleep deprivation also results in decreased cognitive function, negative mood states, as well as impaired reaction time and concentration. Long term sleep deprivation only exasperates these deficiencies. Sleep deprivation is also associated with increased levels of the stress hormone cortisol. Chronically high levels of cortisol results in a cascade of negative health effects including but not limited to:
Lower immunity
Slowed wound healing
Blood sugar imbalances
Decreased bone density (can lead to stress fractures)
High blood pressure
Impaired cognition
Inhibited thyroid function*
*Inhibited thyroid function creates a host of issues including poor calcium absorption, fatigue, muscle weakness, depression, bodyweight issues (loss or gain), hair loss, memory problems, heart-rate disturbances, and other health issues.
Long term sleep deprivation only exasperates the negative health and performance consequences of insufficient sleep.
Most teenage and adult athletes are not getting enough sleep. In this fast-paced society people are constantly trying to squeeze a little more into their day, and sleep is often sacrificed. Unfortunately, the result is a drop in performance and compromised health. Make the decision today to do the easiest thing possible to improve your performance. Create time in your schedule to get the sleep your body needs and craves. If you are a coach, you can educate your athletes about the negative impact of sleep deprivation. It could be the single most important performance enhancement tip you impart.
