dc.description.abstract | The aim of this study was to assess the daily fluctuations in strength and
endurance performance and to examine chronic adaptations to time-of-dayspecific
same-session combined strength (S) and endurance (E) training over the
24-week training period in previously untrained men. Participants were
assigned to the morning (m) or evening (e) E+S or S+E group (mE+S n=9; mS+E
n= 9; eE+S n=12, eS+E n=12) and trained 2-3 d·wk-1 in the respective time-ofday
and training order. In the total group of participants, isometric strength and
maximal cycling performance were, respectively, 4.5% and 1.5% higher in the
evening compared to the morning. Based on the time-of-day of peak isometric
strength performance, high morning performance (n=8), high evening
performance (n=19) and neutral types (n=45) were identified. This grouping
was valid also for endurance performance. Strength and endurance
performance increased in the morning and evening in all training groups over
the 24-week training period. Isometric force and EMG activity increased more
in S+E compared to E+S, when measured in the evening. Maximal cycling
performance increased more in E+S compared to S+E. Muscle hypertrophy was
similar between the groups after the first 12 weeks, but evening training led to a
larger increase over the weeks 13-24. Serum cortisol and testosterone showed a
typical diurnal variation and no changes were observed after 24 weeks of timeof-
day-specific training. Motivation to participate to the present training
program showed a tendency to decrease after prolonged training in the
morning hours. Evening training, however, led to worsened perception of time
management. These results suggest that strength as well as endurance
performance fluctuates over the day, however, the time for peak performance
varies between individuals. In adaptations to combined training, the E+S order
may potentially inhibit neural adaptations and thereby hinder adaptations in
isometric strength performance, whereas in the S+E order the fatigue from the
strength session may inhibit adaptations in endurance performance. Therefore,
if combined training is performed over prolonged periods of time, training time
and order should be selected based on the personal training goals.
