Time-of-Day Variation in Knee Extensor Strength and Fatigue Is Associated With Circadian Phenotype in Healthy Young Adults

Time-of-day variation in neuromuscular performance is well established, but the contribution of circadian phenotype remains unclear. This study examined whether maximal knee-extensor strength and fatigue resistance differ between morning and evening and whether chronotype and act...

Time-of-day variation in endurance and strength performance, and physiological state across the waking day

= 0.114) were unaffected. Short-duration cycling performance and handgrip strength are enhanced during the late afternoon and early evening and occur alongside coordinated temporal variation in physiological and perceptual state. These findings highlight time-of-day as a meaningf...
