Résumé

CONTEXT: Strength/resistance training volume has historically been supported in the American College of Sports Medicine recommendations. However, for the back muscles, exercise prescription related to the number of sets, such as single vs. multiple, is not well established in the literature.

OBJECTIVE: The purpose of this study was to compare the effects of two training volumes on strength and endurance of back extensor muscles in untrained young participants, with regard to a repeated measures design.

DESIGN: Randomized controlled trial.

SETTING: Laboratory of functional evaluation and human motor performance.

PARTICIPANTS: Forty-four untrained young participants (mean age = 21 yrs) were randomized into three groups: single set (SSG, n = 14), multiple sets (MSG, n = 15), and untrained control (CG, n = 15).

INTERVENTION: The SSG and MSG underwent a 10-wk progressive resistance training program (2 days·week-1) using a 45° Roman chair.

MAIN OUTCOME MEASURES: Back maximal strength (dynamometer) and isometric and dynamic endurance (time-limit, trunk extension-flexion cycles, and electromyography muscle fatigue estimates).

RESULTS: The results showed differences between the MSG and control group for isometric endurance time (mean 19.8 seconds, 95% CI 44.1 to 4.8), but without time intervention significance. Significant improvement after training (P < 0.05) was found predominantly during dynamic endurance (number of repetitions) for both the MSG (+61%) and SSG (+26%) compared to pre-intervention, while the control group reported no benefit. There was no significant (P > 0.05) difference in either strength or electromyography estimates after training.

CONCLUSIONS: Both multiple and single volume training were efficient in promoting better back endurance during dynamic performance based on mechanical variables (time and number of repetitions).
