Can Resistance Training at Slow Versus Traditional Repetition Speeds Induce Comparable Hypertrophic and Strength Gains?

The relationship between force and velocity during resistance training can dictate subsequent gains in strength and hypertrophy. Repetition duration (time elapsed during concentric, eccentric, and rest phases) can be manipulated to maximize force or velocity. Based on this current literature review, variation in repetition duration seems to induce similar changes in strength and/or hypertrophy in both novice and experienced lifters. However, relatively faster repetition durations can produce marginal increases in measures of strength and power, and may be more effective for experienced lifters. Although minimally impactful for untrained populations, manipulating repetition duration may be important for athletes training to maximize transfer to sport.
