Onset, offset, duration and frequency of meals (breakfast, lunch and dinner) and sleep periods (night sleep and daytime naps) for morning exercise, evening exercise and control weeks. Onset, offset and duration are expressed as hours and minutes and frequency as a percentage (Mean ± SEM). Different letters indicate significant differences between experimental situations in each variable.
