Oct 29, 2024 Professor Karyn Esser, a leading expert in muscle strength and circadian rhythms at the University of Florida, sheds light on how our muscle strength varies throughout the day. Discover why late afternoons, particularly around 4 to 5 PM, are prime times for peak performance. Delving into the interplay of circadian rhythms and gene expression, she explains how timing can enhance muscle recovery and exercise efficiency. Karyn also discusses the impact of aging on these rhythms and suggests strategies for maintaining optimal muscle health.

Episode notes
Peak Muscle Strength
- Muscle strength peaks in the afternoon, around 4 or 5 p.m., for most people.
- This phenomenon is remarkably consistent across age and gender, suggesting a link to our internal body clock.
Age and Circadian Rhythms
- Circadian rhythms, including those affecting muscle strength, may weaken with age.
- This could explain reduced strength differences between different times of day in older adults.
Clock-Regulated Genes
- Genes in muscle cells are regulated by the body clock throughout the day.
- This means different genes are activated at different times, optimizing the muscle for various functions like energy production and repair.
