Introduction:

Research on the incidence of appendicular muscle mass in muscle strength in healthy and clinical populations is scarce, making it difficult to practice and prescribe exercise for health professionals.

Objective:

Determine the relationship between lower limb muscle mass and maximum repetition in half squat in subjects trained in strength training with overloads.

Methods:

Descriptive-correlational study with a sample of ten men's convenience (age 17,40 ± 2,32 years, a size of 172,10 ± 5,76 cm and a body mass of 79,13 ± 19,54 kg), the maximum strength was evaluated through a maximum repetition test in the half squat exercise, and the muscle mass of lower limbs was estimated through a predictive equation. The PSPP statistical package (95 % confidence level and a p-value of 0,05) was used for statistical analysis using the normality tests (Shapiro-Wilk) and Pearson correlational coefficient.

Results:

The muscle mass of lower limbs and the maximum repetition in half squat was presented a normal distribution (p > 0,05), while the relationship between the muscle mass of lower limbs and the maximum repetition in the half squat was negative and not significant (r = -0,45; p > 0,05).

Conclusion:

The muscle mass of lower limbs is negatively and not significantly related to the maximum repetition in half squat in subjects trained in strength training with overloads.
