Relationship Between Appendicular Muscle Mass and Maximum Repetition in Physically Active Subjects

Abstract

The objective of this study was to determine the relationship between appendicular muscle mass and maximum repetition (RM) on squat with bar (SB), banch press (BP) and deadlift (DL) in subjects physically active practicing bodybuilding. This correlational study was developed with a quantitative approach and design of field, twenty trained healthy subjects (14 men and 6 women) in training with overloading voluntarily participated in this study. Statistical analysis consisted of applying the Shapiro-Wilk normality test and the Pearson correlation coefficient, was used the statistical package SPSS IBM V.22 with a 95% confidence level so that the employee p-value was 0,05. The men had a muscle mass in upper limbs (MMUL) of 6,49+1,37 kg and a muscle mass in the lower limbs (MMLL) of 11,98+1,43 kg. On the other hand, women showed a MMUL of 3,90+0,63 kg, and at MMLL of 8,43+1,05 kg. The men obtained an average in the 1RM in SB of 122,09+28, 54 kg, 1RM BP of 83,07+24,54 kg and 1RM DL of 94,58+16,49 kg, while women had 1RM SQ of 93,40+24,60 kg, 1RM PB of 28,13+13,38 kg and 1 RM DL of 71,81+8,75 kg, which men presented MMUL best results, position and 1 RM with regard to women, on the other hand was a normal distribution of data (p>0,05), Although was not evidence a significant relationship between the MMUL and MMLL with 1 RM of the evaluated exercises (p>0,05). Therefore, it is concluded that not significant relationship between appendicular mass muscle and maximum repetition in the exercises SQ, BP and DL practitioners of bodybuilding.
