Resumen
To compare the effects of high-load, low-repetition maximum (LRM) and low-load, high-repetition
maximum (HRM) resistance training regimens on muscular fitness in untrained adolescents.
Forty-five untrained adolescents of both sexes (13.7±0.8 years; 161.3±7.5 cm,
56.8±13.4 kg) were randomly assigned into one of three groups: 1) LRM (n = 17): volunteers
performed three sets of 4-6-repetition ma ...

To compare the effects of high-load, low-repetition maximum (LRM) and low-load, high-repetition
maximum (HRM) resistance training regimens on muscular fitness in untrained adolescents.
Forty-five untrained adolescents of both sexes (13.7±0.8 years; 161.3±7.5 cm,
56.8±13.4 kg) were randomly assigned into one of three groups: 1) LRM (n = 17): volunteers
performed three sets of 4-6-repetition maximum (RM); 2) HRM (n = 16): volunteers performed
three sets of 12–15 RM; and 3) control (CON, n = 12). Training was performed two
times a week for 9 weeks. After training, there were significant increases in 1 RM chest
press (LRM = 14.8%and HRM = 14.2%, p<0.05) and squat (LRM = 26.4%and HRM =
25.7%, p<0.05), with no differences between the LRM and HRM groups (p>0.05). Additionally,
muscular endurance increased significantly for the chest press (LRM = 14.5% and
HRM = 21.8%, p<0.05) and squat test (LRM = 31.4% and HRM = 32.4%, p<0.05) following
resistance training, with no difference between the LRM and HRM groups (p>0.05). These
results suggest that both high-load, low-repetition and moderate-load, high-repetition resistance
training can be prescribed to improve muscular fitness in untrained adolescents. [--]
