It has been shown that lack of adequate sleep can decrease the reduce tolerance to training, alter mood, increase perception of fatigue and negatively affect the physiological mechanisms responsible for adaptation from the stresses of training. Hormonal secretion during sleep is one of the most important factors influencing recovery; after all, the purpose of sleep is to induce a state of recovery in the body. Anabolic (muscle-building) hormone concentrations and activity increase during sleep while catabolic (muscle-wasting) hormone concentrations and activity decrease. Disrupted or shortened sleep will negatively influence the effects of these anabolic hormones.
Our Advice: Try to develop a regular sleeping routine where you go to bed at a similar time each night of the week. Remove distractions such as, light, smart phones and television watching. If possible, try for 8 hours per night and/or fit in an afternoon power nap for 30 minutes to rejuvenate the body.
