This finding can be interpreted in light of the muscle mass data collected over time: both groups largely maintained muscle mass (non-significant paired t -tests), and the between-group comparison showed a trend favoring HIIT (Δ +0.63 kg; p = 0.06; d = 0.81), without translating into significant changes in mesomorphy.

Pre–post comparisons further indicated that HIIT was associated with a greater reduction in fat mass (−2.69 kg) compared with LISS (−1.69 kg), with a medium-to-large effect size (d = −0.58), although the between-group comparison did not reach statistical significance ( p = 0.13).

This result suggests that muscle mass trajectories differed between groups, with a favorable trend in the HIIT group, which showed a slight increase, compared with the LISS group, which exhibited a slight decrease.
