The Effect of Circadian Rhythm on Physical Performance in Healthy Male

Status Not yet recruiting

Clinical Trial Summary

Little is known about optimizing the timing of exercise periods to maximize the health benefits of exercise. Furthermore, exercise is a potent modulator of skeletal muscle metabolism and it is clear that skeletal muscle has a robust circadian profile. Circadian rhythms can be observed in behavior, physiology, and metabolism. Various studies show that exercise changes the rhythm of the clock machines in skeletal muscle. Studies examining the relationship between exercise, especially strength training, and circadian rhythm are quite limited in the literature. Although some studies have shown that force peaks in the afternoon/evening hours, regardless of muscle group and contraction speed, there are no studies on how much this time interval varies from person to person and chronotype. The aim of this study is to investigate to what extent strength training given at appropriate times for morning, evening and intermediate chronotypes creates changes in performance in healthy adult male individuals.

Clinical Trial Description

After participants are informed about the research, evaluation and exercise protocol, their signed consent will be obtained. The Morningness-Eveningness Questionnaire will be applied until 30 participants with morning type and 30 evening type chronotypes are reached. (Estimated for 100 students) After determining 30 morning type and 30 evening type participants, isokinetic evaluations will be made and vertical jump heights will be measured (T0). Then, 15 morning type participants will be included in the morning exercise program (08:00) and 15 morning type participants will be included in the evening exercise program (18:00). 15 evening type participants will be included in the morning exercise program (08:00) and 15 evening type participants will be included in the evening exercise program (18:00). Thus, some of the participants from both morning and evening groups will be included in strength training for 6 weeks, at a time appropriate to their chronotypes, and some at a time incompatible with their chronotypes. Isokinetic evaluations and vertical jump height measurements will be repeated at the end of the strengthening exercise program, which will last 3 days a week for 6 weeks, a total of 18 sessions. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
