Time of training doesn't matter for power production

Effects of 5 Weeks of Training at the Same Time of Day on the Diurnal Variations of Maximal Muscle Power Performance

The purpose of this study was to investigate whether maximal muscle power production in humans is influenced by the habitual time of training to provide recommendations for adapting training hours in the month preceding a competition. Sixteen participants performed maximal brief squat and countermovement jumps and short-term cycle sprints tests before and after 5 weeks of training. Subjects were randomly assigned to either a Morning-Trained Group (MTG, 7:00-9:00 hr) or an Evening-Trained Group (ETG, 17:00-19:00 hr). They trained and performed the evaluation tests in both the morning and evening in their naturally warm and moderately humid environment. The results indicated a significant increase in performance (approximately 5-6% for both tests) after training for both groups but failed to show any time-of-day effect on either performance or training benefit. These findings could be linked to the stabilization of performances throughout the day because of the passive warm-up effect of the environment. In summary, our data showed that anaerobic muscle power production could be performed at any time of day with the same benefit.

My purely anecdotal evidence on my own workouts is that my early morning (~7am) workouts are not as productive as a slightly later morning (~8'ish) or late afternoon workout, from both strength and met-cond perspective. Can't explain, perhaps it's an issue with how long after I've eaten, versus just the time of day.

There was an earlier study I posted concluding that training when you're most used to training is the best...or something like that.

Still doesn't correlate; I'm used to working out early in the morning; but on the occasions when I work out on saturday late morning or afternoon (after work), I always feel stronger/better for both strength and met-cond workouts.
