How To Optimize Sleep For MMA & Combat Sports

December 10, 2021

Everyone evolved with sports training (mainly coaches and athletes) recognize the importance of training and nutrition as essential in a high-performance sports environment. However, one factor is constantly underestimated: the recovery process.

A triad composed of three factors: training, nutrition, and adequate recovery is essential for sporting success. It is time to be aware of the importance of sleep in the recovery process for the fighters.

An Overview Of Sleep For Fighters

Among the possibilities of recovery strategies, sleep can be a crucial factor in restoring the body from the central and peripheral fatigue inherent in physical training.

Sleep is defined as a reversible behavioral state in which the individual has relative immobility and an increased threshold of response to external stimuli [1].

Sleep has two primary physiological parameters: REM sleep rapid eye and NREM sleep non-rapid eye movement. NREM sleep is divided into three stages:

Sleep For MMA
  • Stage N1 - The transition between wakefulness and sleep.
  • Stage N2  - ± 20 minutes, being advanced by shorter periods of rhythmic and fast brain wave activity (at this stage, the body temperature starts to decrease).
  • Stage N3 - The transition between "light sleep" to " deep sleep. There is a decrease in sympathetic activity, heart rate, and blood pressure. On the other hand, there is an increase of neuroendocrine activity (peaks in the secretion of some hormones such as Growth Hormone (GH).
  • REM Sleep - Occurs an increase in breathing rate, brain activity, and other body systems being more active, while the muscles are more relaxed/paralyzed. At this stage occurs the dreams and mainly cognitive restoration.

A sleep cycle typically is about 90-120 minutes, with 4-6 cycles per night.

Impact Of Poor Sleep Habits On Fight Performance

Lack of sleep can expose combat athletes to detrimental effects regarding physical performance and immune function, cognitive capacity, and psychomotor performance.

Thus, it is observed that sleep restriction can expose athletes to detrimental effects on combat sports performance. Souissi et al. [2] investigated that partial sleep deprivation at the beginning or end of the night can influence the peak performance of judokas before and after the competition.

Regarding sleep variables in professional Mixed Martial Arts (MMA) athletes, Peacock et al. [3] showed that high sleep latency was associated with lower values of physical measures (cardiorespiratory fitness, recovery of heart rate, the height of vertical jump)

In contrast, athletes who showed consistency in their sleep routine obtained better performance test results during the fight camp period.

Endocrine aspects are also changed when there is nocturnal sleep debt. In a study published by Leproult & Van Cauter [4] (2011), 5 hours of sleep per night for a week decreased testosterone levels in men by 10% to 15%, with this decrease associated with a low sense of well-being, mood, and physical vigor.

Sleep restriction also influences the immune system, as shown by Cohen et al. [5], where participants who had a total sleep time of fewer than 7 hours were 2.94 times more likely to develop a cold when compared to participants who slept 8 hours or more a night.

What Causes Sleep Restriction In Fighters

  • Change in the sleep pattern after exposure to light irradiated by electronic devices  [6] due to the suppression of melatonin (a hormone that modulates the sleep-wake cycle). When using these devices hours before bedtime, the human biological system is signaled that it is still "day," increasing the alertness, which can delay sleep onset [7].
  • Pain tends to limit the depth of sleep. The correlation between sleep quality and pain in athletes is more evident when there are more significant areas of pain in the body [8].

Combat sports athletes still have some specific demands that change factors for a good sleep routine:

  • Unorthodox preparation schedule (fights are marked and unmarked frequently, making this athlete have to be “always” ready to fight).
  • Frequent transmeridional flights.
  • Weight cutting can influence the athlete's sleep pattern and, consequently, the fighter's performance.

Strategies For Sleep Optimization in Combat Sports athletes

Napping can benefit combat athletes, especially those who wake up early to start their training routine [9]. Another good strategy is creating sleep habits like going to bed at the same time each night and getting up at the same time each morning (including on the weekends).

Keeping the bedroom like a "cave" (quiet, dark, relaxing, and at a comfortable temperature); and removing electronic devices before sleep and avoiding large meals, caffeine, and alcohol before bedtime.

You can use other strategies to improve sleep patterns in combat athletes. For example, bright ­light therapy appears to have helped delay or advance the sleep/wake cycles in athletes [10]. The modulation of sleep/wake cycles improved the athletes' reaction times, a crucial attribute for elite ­level fighters.

The use of artificial light­ emitting might be a valuable procedure for athletes who are competing in different time zones or at unusual times and need to adjust their sleep/wake cycles to conform to the competition timetables.

Because circadian rhythms have a direct influence on the body and affect such variables as muscle strength, flexibility, sensorimotor coupling, and perceptual and cognitive functions.

For instance, I recommend the Re-Timer light therapy glasses because they are portable light therapy that regulates the body clock. The light suppresses the body's melatonin production, enabling us to change the time we feel tired and therefore change our sleep. This leads to increased energy levels and better sleep habits and quality by regulating the production of the hormone melatonin and optimizing the circadian rhythm.

Considering these factors, modifying the sleep/wake cycle (phase delay or advance) by using bright light therapy and manipulating when the exposure time occurs can optimize athletes' performance. This happens through modulating core temperature and the secretion of melatonin, which promotes higher levels of alertness in the athletes. Especially if the competition happens when physiologically it is time to sleep [10].

For example, to minimize the effects of the jet lag when Rodrigo Nascimento fought at UFC Fight Night in Abu-Dhabi, we had to synchronize his biological clock (from Florida to Las Vegas - USA) to a new time zone. 

In addition, the fight happened at a local time (Abu-Dhabi) when the athlete would be physiologically sleeping. So, the acclimatization starts two weeks before the flight. The athlete is exposed to specific wavelengths of light for a prescribed period (30 to 50 minutes) at a specific time of day.

So, despite the importance of sleep for athletes, the analysis and monitoring (I recommend the Instruments Condor) should be done with a device. Actimetry is a non-invasive method that analyzes the sleep/wake rhythm for long periods, from days to months.

However, this data about sleep in fighters have still been neglected. Thus, sharing this information about the need to establish a consistent sleep routine and specific interventions can ensure that athletes have optimized physical and cognitive functions throughout the training/competition process, which is essential for sports success.
