The absolute values of strength were corrected by the Fat-free mass (Kg) of the arm (handgrip strength) and leg (MVIS). Kg, kilogram; Kgf, kilogram force.

PLHA, people living with HIV/AIDS group; CG, control group (people without HIV/AIDS); MVIS, maximal voluntary isometric strength.

Interaction = group vs. time interaction two-way repeated measures ANOVA

aSignificant difference compared to the Pre-TR, HIV group (training effect, p < 0.05).

bSignificant difference compared to the Post-TR, HIV group (detraining effect, p < 0.05).
