New research emphasizes the crucial role of timing in maximizing exercise performance and minimizing injury risks. Historical instances, such as Usain Bolt’s record-breaking 100-meter sprint at the 2009 World Championships in Berlin, highlight how time of day impacts athletic achievement. Many world records, particularly in strength and endurance events, are often set during the late afternoon or evening, likely due to the body’s peak physiological conditions at these times.
For everyday fitness enthusiasts, understanding the ideal time for workouts is essential. “When considering any aspect of sport, from sports medicine to exercise response, the time of day is a significant factor,” states an expert from the University of Manchester. Research indicates that body temperature peaks in the later afternoon or evening, facilitating faster metabolic processes and efficient nerve signaling in comparison to early morning workouts. Additionally, connective tissues exhibit greater flexibility later in the day, and glycogen stores—vital for energy during intense exercise—are typically at optimal levels.
