From a study measuring performance on cycling, jumping, and sprinting at different times of day:
The [maximal anaerobic power for cycling] and [jumping] were higher at 1400 and 1800 hours than at 0900 hours. The differences between the morning and the afternoon reached 3% (P < 0.05) for cycling and 5%±7% for jumping
P (< 0.01). The time-of-day effect was significant for [flight time during jumping] (
P < 0.05) but not for [ground contact time during jumping]. During the dash-run tests, the differences almost reached significance for [maximal anaerobic velocity] between 0900 and 1800 hours (
P=0.0544). No significant variations were observed between 1400 and 1800 hours for cycling, jumping and running tests. A time-of-day effect in the maximal anaerobic power of cycle and multi-jump tests existed.
From another study measuring aerobic and anaerobic performance during a cycling task Total work performed was 9.6% greater in the afternoon (mean +/- SE, 348.8 +/- 40.6 J.kg-1) compared to the morning (318.2 +/- 39.5 J.kg-1). The greater amount of work in the afternoon was associated with a 5.1% higher aerobic power and a 5.6% larger anaerobic contribution.
From another cycling task study: Time to exhaustion was 9% greater (p<0.01) in the PM (214±43 sec) than in the AM (196±38 sec). Peak VO2 was 7% higher (p<0.01) in the PM (3.34±1.00 1.min-1) in the AM (3.11±0.98 1.min-1). The aerobic system responded 6% faster (p=0.04) in the PM than in the AM: the time constant describing VO2 kinetics was 33.5±5.7 sec in the PM and 35.5±5.5 sec in the AM. However, there were no significant correlations (p≥0.20) between the AM-PM differences in time to exhaustion, time constant of the response, or peak VO2. The findings confirm previous reports of a time of day effect on time to exhaustion in high-intensity exercise. It was also concluded that there is a higher peak VO2 in the PM than in the AM. In addition, there is a time of day effect on VO2 kinetics, with the aerobic system responding faster in the PM than in the AM.
