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.

Interventions

Theraband Strengthening Exercise Program

Resisted knee flexion in prone position and resisted knee extension in seated position (for dominant leg) and bilateral squats were practiced in 3 sets of 12 repetitions. Participants rested for 30 seconds between sets. The program, which lasted approximately 30 minutes in total, continued for a total of 6 weeks, the first 3 weeks with the red theraband and the last 3 weeks with the black theraband. 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).
