Abstract
Purpose
The purpose of this study was to examine the effects of an additional set of exhaustive exercise before traditional hypertrophic training on quadriceps muscle performance in young men.
Methods
Subjects performed maximal dynamic strength (1RM), local muscular endurance (LME), and magnetic resonance imaging (MRI) tests before and after an 8-week hypertrophic training program using a knee extensor machine. After baseline testing, the subjects were divided into 3 groups: untrained control, traditional training (TR), and prior exhaustive training (PE). Both the TR and PE groups trained using the same training protocol (2 days week−1; 3 sets of 8–12 repetitions at 75 % of 1RM); the only difference was that the PE group performed an additional set of exhaustive exercise at 20 % of 1RM before each training session.
Results
After 8 weeks, the PE group experienced a greater (P < 0.05) increase in 1RM, cross-sectional area, and LME than the TR group. Additionally, no changes (P > 0.05) in daily dietary intake were observed between groups.
Conclusion
These results suggest that the inclusion of a single set of exhaustive exercise at 20 % of 1RM before traditional hypertrophic training can be a suitable strategy for inducing additional beneficial effects on quadriceps strength, hypertrophy, and endurance in young men.
