Sleep of Athletes - Problems and possible Solutions
Transcript of Sleep of Athletes - Problems and possible Solutions
Jael Sleep in Athletes Human Performances and Sleep
Sleep Deprivation Effects
Effects of Exercise on Sleep
Good Sleep and Bad Sleep
Research Methods Used Introduction Schematic representation of the relationship between sleep and exercise Performance Peaks > Afternoon or Early Evening
Circadian Rhythm of Vigilance??
What would "Vigilance" be in Athletes??
What happens when they do not have suficiant SLEEP??
Naps are there to save the day!! Circadian Rhythm of Athletic Performances (Arrow 1) Environmental light > Principle time givers
Other time givers > Social Rhythms, Meals timing, Sleep – Wake Cycle, Regular Physical Activity
What effect would physical activity have on humans??
What is the difference between sedentary people and Athletes?? Effect of exercise on circadian rhythms (Arrow 2) Two main electrical states of sleep:
Slow wave sleep
REM (rapid eye movement) sleep Sleep for the athlete (arrow 3) Neuronal activity becomes synchronised
Produces electroencephalographic waves
Without it growth hormone cannot be released from the pituitary gland
Pituitary gland? Slow wave sleep The brain is very active
Produces EEG waves
After REM sleep loss, procedural memory and motor skills can be affected
The brain is partly disconnected from the body REM sleep A general decline in performance
Mood, psychomotor and cognitive functions are affected
Athletes’ sleep could be reduced by anxiety, the new environment, jet lag..
Sleep deprivation slow glucose metabolism by as much as 30-40% Sleep deprivation Improved quality of sleep for those individuals who exercise
Increase in total sleep time
Sleep has an effect on the circadian rhythm of vigilance
Exercise changes the equilibrium between waking and sleeping
Assumptions that late exercise disturb sleep Effects of exercise on sleep and on the waking state (arrow 4) Sleep and exercise are interdependent, influenced by the body clock that drives the sleep-wake cycle
Athletic performances are dependent on both quality and quantity of sleep
Factors to improve performance:
- respect greater amount of sleep required
- sleep to be taken in optimal environment
- prevent anxiety
- take additional napps Conclusion
