C Control, M medium intensity, H high intensity, Sint short interval, Lint long interval, CF condition factor, TGC thermal growth coefficient, week (W) 6: End of first six weeks of training under a short day light photoperiod. W 11: End of 10 weeks of training and one week of detraining. Means in the same row with different superscripts letters are significantly different based on one-way ANOVA (p < 0.05). Differences between the groups were assessed by the least-squares means procedure. Data are means ± SEM.
