The Power of Sleep for Athletes
It’s not uncommon for an athlete to put 100%
focus into their weight and nutritional regimens while
training for their chosen sport. A workout log book
and weekly nutritional log sheet are essential items
when striving for goals of lean muscle mass and decreased
body fat. However, when the gains suddenly screetch
to a halt, or energy and strength levels begin to decrease
drastically in the weight room, its time to examine
an often overlooked variable- sleep.
As an athlete, it is just as important to keep track
of sleeping hours and quality of sleep as it is about
weights being lifted and food being consumed. Getting
the most out of your sleep definitely has its advantages:
• Increased mood
• Improved reaction time
• Improved alertness
• Weight control
• Increased growth hormone
With proper sleep, the above advantages all add up
to a greater performance both on and off the field.
Without it, athletes often find themselves adding more
time and volume to their training which has an increasingly
detrimental effect on body repair and performance.
Sleep is divided into Non Rapid Eye Movement (NREM)
with accounts for approximately 70% of total sleep
time, and Rapid Eye Movement (REM) with accounts for
the remaining 30%. During NREM sleep patterns, the
body undergoes many relaxing phases, and passes through
4 of the following stages:
Stage 1: Drowsiness; low rolling
eye movements; mental relaxation; 5% of the total sleep
time.
Stage 2: Light Sleep; can be easily
aroused or awoken from sleep; 90 minute cycle and occupies
approximately 45-60% of sleep.
Stage 3 and 4: Deep Sleep; very relaxed
state; slow regular heartbeat and respiratory rate;
relaxed muscles; 7% of total sleep time in stage 3
and around 11% in stage 4. It is during the 3rd and
4th stages that growth hormone is secreted by the pituitary
gland to help the body and muscles recover from intense
workouts
REM sleep represents stage 5, which is characterized
by a rapid, flickering movement of the eyes. Temporary
paralysis of body is also natural in this stage, allowing
the sleeper to explore the vividness of dreams. REM
sleep accounts for approximately 20-25 % of a normal
nights sleep and takes approximately 90 to occur. This
stage is represented by “periods”, in which
the sleeper goes in and out of REM in shorter periods,
back to stage 2, followed by cycles of reentry to REM.
In next month’s continuation, we shall examine
ways to improve sleep, as well as a powerful, yet natural
supplement that every athlete should use for sleep
and recovery purposes.
