Few of us consider the importance of sleep when considering what makes sportsmen great. However a lot of the top athletes in the world claim that getting enough sleep is crucial to their training and to performing effectively.
For instance, Serena Williams aims to sleep for eight hours every night. LeBron James of the NBA tries for eight to ten hours each night, while Tom Brady of the NFL claims he gets at least nine hours of sleep each night by going to bed early.
It makes sense given that sleep is essential for metabolism, tissue growth and repair, as well as the proper functioning of memory, reaction time, and decision-making. Sports performance is impacted by each of these processes.
But getting enough sleep has benefits for everyone, not just athletes. By obtaining enough rest each night, even casual gym attendees can maximise the advantages of exercise for their fitness and health.
The following are only a few benefits of sleep for fitness: aerobic exercise
Enhancing aerobic fitness is a key benefit of exercise. It boosts both effectiveness (allowing you to run or bike faster while carrying a higher weight) and aerobic capacity (meaning your body requires less oxygen to run or cycle at the same pace).
The mitochondrial activity of the organism is a factor in better aerobic fitness. Muscle cells contain tiny structures called mitochondria, which are in charge of generating the energy the muscle needs to work.
Muscle growth
Muscle protein synthesis, a process that results in the addition of new proteins to the muscle structure, is what causes muscles to expand. Exercise and food consumption, particularly protein, accelerate this process, which can remain for as least 24 hours after a workout.
Anabolic hormones
Hormones work as chemical messengers that support a variety of bodily processes, including tissue growth and development. Anabolic hormones are those that are involved in these building activities.
Two anabolic hormones, testosterone and growth hormone, which are released while you sleep, may also be crucial for your body’s ability to adapt to exercise and recover from it. These hormones function in the body in a variety of ways and are associated with better body composition (lower body fat and higher muscle mass). For exercise and health, having more muscle mass and less body fat can be advantageous.
Refuelling after exercise
Glucose, or sugar, is a common fuel source during exercise. To meet the demands of activity, muscles store glucose from the foods we eat as glycogen. After exercise, replenishing glycogen stores is an important step in the healing process. When the right nutrients are consumed, it can take up to 24 hours for stores to be completely replenished. In order for muscles to absorb glucose and produce glycogen, the hormone insulin may be required.
How to sleep well
Here are some strategies to make sure you get enough sleep each night because it is obvious how crucial sleep is for your fitness: Create a regular nighttime routine by doing activities that help you unwind and relax before going to sleep, such reading a book or listening to calming music. A hot bath or shower before bed might also be helpful because the subsequent drop in body temperature can help you nod off more quickly.
