Morning vs Evening Workout: Which Is Better for Sports Training?

Short answer
Strength and power tend to peak in the late afternoon and early evening, when core body temperature is highest. Mornings suit skill work, technical practice and consistency, because fewer things can displace them. The best training time is the one you can repeat, but if competition is in the morning, train some sessions then.
What changes across the day
Body temperature, reaction time and peak force output all rise through the day and generally top out in the late afternoon. That makes evening a reasonable default for heavy strength and power work.
Mornings have a different advantage: nothing has happened yet. No work, no school, no fatigue accumulated, and far fewer reasons for the session to be cancelled.
The rule that overrides all of this
Train when your event is. If you compete at 9am, some of your training must happen at 9am, because the body adapts to the time it is asked to perform.
Beyond that, the timing difference is small compared with the difference between training four times a week and training twice.
Frequently asked
Is it bad to train in the morning?
No. You may need a longer warm-up because body temperature is lower, but morning training is effective and often more consistent.
Should I train at my competition time?
Yes, at least some sessions. Performance is partly time-of-day conditioned, so rehearsing at the competition hour is a genuine advantage.
