The majority of the research on sleep is focused on sleep deprivation and how it affects performance and health. But more and more studies are being done on sleep extension and its possible effects on athletic performance. The importance of sleep in recuperation and performance is generally acknowledged.

Despite this, it’s thought that more than a third of Americans sleep too little.

The American Academy Of Sleep Medicine advises people in the age range of 18 to 60 to get at least seven hours of sleep every day.

Reasons Why Sleep Is Vital

Failure to comply with this criteria has been linked to a number of chronic diseases and performance- and health-damaging effects, including diabetes, high blood pressure, heart disease, and stroke.

One study that examined how sleep deprivation affected resistance training performance discovered a significant decline in bench press, deadlift, and leg press strength. The researchers also noticed2 higher scores for subjective sensations of difficulty and drowsiness. Strength losses persisted until the fourth straight night of sleep deprivation. Even Nevertheless, after just one night of nocturnal sleep restriction, levels of mood, exhaustion, and other subjective sleep deprivation rose.

Limiting Sleep Has Negative Effects

According to a study that examined how endurance-trained athletes’ circulatory, respiratory, and metabolic systems responded to sleep deprivation:

“When compared to the data from the baseline night, there were statistically significant increases in heart rate (P less than 0.05) and ventilation (P less than 0.05) with submaximal exercise following partial sleep deprivation. Even though the maximal sustained exercise intensity was the same, both measures were also significantly improved at maximum activity, while the peak oxygen consumption (VO2) decreased (P less than 0.05).”


According to a 2009 article by Edwards et al., sleep restriction lowers alertness, coordination, and other psychomotor features. Participants in the sleep-restricted group also performed worse when throwing darts.

Research has repeatedly shown that sleep restriction impairs attentional systems like reaction time and coordination. Sleep is recognized to have a significant role in cognitive restitution.

It has also been demonstrated that sleep restriction, in varied degrees, can lengthen the time it takes for performance to return to normal.

chronic lack of sleep need more time than acute limitation to reach baseline after refractory phase.

According to a study that examined how sleep deprivation affected sprint performance and muscle glycogen levels:

“Male team-sport athletes’ performance during intermittent sprint training was negatively impacted by lack of sleep, along with the resulting declines in muscle glycogen and perceptual stress.”

Numerous other research have shown a clear correlation between poor sleep and weakened muscle function.

Additionally, there are significant inter-individual variations in resilience to sleep loss, with some people exhibiting a bigger performance decline than others under comparable circumstances.

Composition of the Body and Performance

The relationship between body composition and performance is also important but perhaps less visible.

This is perhaps more applicable to sports where weight divisions exist and power-to-weight ratios are important performance factors.


Lack of sleep has been demonstrated to have major negative effects on body composition, with one study revealing:

“Sleep deprivation enhanced the loss of fat-free body mass by 60% (1.5 vs. 2.4 kg; P = 0.002) and decreased the proportion of weight lost as fat by 55 percent (1.4 vs. 0.6 kg with 8.5 vs. 5.5 hours of sleep opportunity, respectively). Along with it, there were indicators of improved neuroendocrine tolerance to calorie restriction, elevated appetite, and a change in the relative substrate utilization toward reduced fat oxidation.”

Therefore, getting too little sleep can negatively affect your body’s composition.

Effects of Sleep Extension on Athletic Performance

After going over a few possible effects of sleep deprivation, let’s switch gears and talk about the opposite.

A 2011 study looked into how sleep extension affected several athletic performance metrics and other cognitive measurements. The scientists discovered:

“Total objective nightly sleep time increased by 110.9 79.7 min (P 0.001) after sleep extension compared to baseline. Following sleep extension, subjects ran a faster timed sprint (16.2 0.61 sec at baseline vs. 15.5 0.54 sec at conclusion of sleep extension, P 0.001). With a 9 percent increase in free throw efficiency and a 9.2 percent increase in 3-point field goal efficiency, shooting accuracy improved (P 0.001). Following sleep extension, the mean PVT reaction time and Epworth Sleepiness Scale scores reduced (P 0.01). Increased vigor and decreased weariness subscales resulted in higher POMS scores (P 0.001). During training and games, subjects also reported higher overall assessments of their physical and mental health.”

As you can see, performance has improved from the starting point.


In the beginning, subjects slept between 6 and 9 hours per night, but after the intervention, they were told to record at least 10 hours in bed each night.

It’s crucial to understand that sleeping for 10 hours does not equal sleeping for 10 hours.

The study’s aim was to quantify time in bed, a good proxy for total sleep due to evident limits. Adopting a 10-hour nocturnal sleeping schedule would not always be possible, though.

A bi-phasic (2 phases) or polyphasic (3+ phases) approach to sleep is characterized by a fragmented sleep pattern. Benefits from this strategy have been seen in patients with sleep problems.

It has also been demonstrated that napping significantly enhances cognitive function.

Utilizing naps can be a useful method to increase total sleep, boost recovery, and improve athletic performance if prolonging nighttime sleep is not a viable option. Total cumulative sleep and using trembolona enantato throughout the day is a reasonable indicator for recovery and athletic performance.

A 10-minute snooze can dramatically increase alertness and cognitive performance, according to one study. Taking naps for more than 30 minutes has also been proven to offer many advantages.

Longer naps, however, could result in a condition called sleep inertia. In essence, this is a time of diminished cognitive function that follows a prolonged slumber (+30 minutes).

Although sleep inertia does not last throughout the entire day, it may be advantageous to schedule longer naps away from mentally taxing activities like work or exercise.

Practical Instructions

An additional tool to improve the quality of your sleep is suggested by the national institute of health.

  • Establish a routine by going to bed and waking up at the same times every day.
  • Workout for 20 to 30 minutes every day, but not more than a couple hours before bed.
  • Avoid consuming alcohol before night and using nicotine and caffeine in the late afternoon.
  • Take a warm bath, read a book, or engage in another calming activity before bed.
  • Make your bedroom a sleeping space by blocking off bright lights and loud noises, maintaining a pleasant temperature, and refraining from using a computer or TV there.
  • Avoid lying awake in bed. Do something else—like reading or listening to music—until you feel sleepy if you’re unable to fall asleep.
    If you have trouble falling asleep or feel worn out during the day, consult a doctor.

Up to 10 hours a night of extra sleep seems to improve performance, according to strong evidence.

However, because recuperation requirements are individualized, the advantage it bestows may differ.

Good fortune!
