As
coaches we often tell our athletes to 'wake up out there!' This call
to alertness might be more than a figure of speech. Sleep deprivation
among youth is a growing national concern. And, we are learning more
about the fascinating linkages between sleep deprivation and athletic
performance. We can help our athletes win and remain safe and healthy
by promoting proper sleep.
1. Four out of five American youth are sleep deprived
According
to the National Sleep Foundation, four out of five Americans age 11-17
are sleep deprived. Experts recommend that school-age children and
teens should get nine hours of sleep a day. Most get one to two hours
fewer than that, and many get even less sleep. This is no big deal on
any given day, but when this happens on a regular basis, chronic sleep
deprivation sets in. It is also worth noting that the large majority
of parents are unaware that their children are sleep deprived.
2. Sleep deprivation is harmful to youth development
In
any given situation, sleep deprivation can hinder awareness, thought
processing, decision making, and reaction time. Over time, chronic
sleep deprivation can alter metabolic processes essential for good
physical and mental health. Studies show that sleep deprived youth are
more susceptible to academic trouble, depression, lack of energy, and
various other physical problems. Most recently, more attention is
being given to the connections between sleep deprivation and childhood obesity, and sleep deprivation and drowsy driving among teens.
3. Sleep deprivation impairs athletic performance
It is no surprise that sleep deprivation impairs athletic performance as well. Here's how:
- In
competition, prolonged sleep deprivation can muddle an athlete's
awareness, decision making, and reaction time. Athletic performance
cannot help but suffer as a result.
- In
training, sleep deprivation can hinder an athlete's energy balance and
muscle & tissue recovery. Sleep deprivation can affect normal
metabolic function, including the production of glucose and cortisal.
Glucose is a primary source of energy for athletes. Cortisol is
essential for tissue repair and growth. Over time, abnormal levels of
glucose and cortisol caused by sleep deprivation can sap an athlete's
energy and diminish the athlete's ability to recover from heavy
training.
- Lack of sleep can also limit an athlete's ability to deeply learn new skills. The
human brain continues to learn subconsciously while we sleep. That's
one reason athletes struggle to learn something new on one day, but be
much more proficient on the following day. Overnight, the new skill
has had a chance to 'sink in' a little deeper. When athletes are routinely deprived of adequate sleep, this learning advantage is compromised..
4. Promoting Proper Sleep
As
funny as it sounds, sleep wins. We can help our athletes stay
healthier and performance better by proactively promoting the value of
adequate sleep.
- Teach
your athletes that sleep wins. Encourage your athletes to view
adequate sleep as a winning practice essential for both recovery from
training and peak competitive performance. Talk about sleep alongside
good nutrition and proper hydration as essential core heath activities
of serious athletes.
- Think
carefully about the impact of the athletic schedule on the 'sleep
banks' of your athletes. Weigh the value of early morning practices
against the overall recovery needs of your athletes. If you have to
hold early morning practices, be aware that they are likely to
underperform for reasons beyond their complete control. Also work with
your athletes to help them maintain a reasonable sleep schedule around
morning practices. Also encourage parents (rather than athletes) to
drive to early morning practices so that athletes can avoid drowsy
driving risks.
- Educate
parents about the importance of sleep for their athletes. Studies show
the vast majority are unaware of their children's chronic sleep
deprivation
Coaching Points
1. Most American youth are chronically sleep deprived, with only 20 percent getting enough sleep on a regular basis.
2.
Sleep deprivation is harmful to youth development, affecting physical
health, mental health, academic performance, and driving ability.
3. Sleep deprivation can also impair athletic performance, training, and learning.
4. Teach your athletes that sleep wins - not just the night before a competition, but every day.
5.
Think carefully about the impact of the athletic schedule - especially
early morning practices - on the 'sleep banks' of your athletes.
6. Educate parents about the importance of sleep for their athletes. Most are probably unaware of the problem.
