Table 4. Relative changes in thickness of PM (pectoralis major), cross-sectional area of TB (triceps brachii, LoH: long head) and TB (LaH: lateral head) and Sum of all three muscles in the ECC and CON groups of women during the Control period (week -1 and 0) and during training Pre-Mid (week 0 and 5), Mid-Post (week 5 and 10), Pre-Post (Week 0 and 10) and during Detraining (Week 10 and 15). Data are Means ± SD.
