Power (strength × velocity) is a crucial component for maintaining independence during aging. Therefore, investigating interventions aimed at improving this physical capacity is essential for this population. The aim of this study is to examine the effects of power training (PT) performed at low to moderate intensity (PTLM; 40-60% of 1-repetition maximum \[1RM\]) and moderate to high intensity (PTMH; 65-80% of 1RM) on muscle power, kinematic gait parameters, strength, muscle thickness, and functional performance in older adults. Participants will be randomly assigned to perform PTLM and PTMH. Data collection will occur before and after familiarization, as well as at weeks 8 and 16 of the training programs. Participants will undergo a series of tests in the following sequence: 1) muscle thickness and 1RM test; 2) muscle power, maximum voluntary contraction, and rate of force development; 3) functional performance. The primary analyses will be conducted on an intention-to-treat basis, comparing the effects of the interventions and groups over time. Generalized Estimating Equations (GEE) will be used, considering the factors of group (2 levels) and time (3 levels). Paired comparisons will be assessed using the Bonferroni post-hoc test to identify significant differences between groups and time points. All tests will be performed using JASP software (version 0.16.4.0), with statistical significance set at p \< 0.05 for all analyses.
