Comparison of the effects of three different resistance training methods on muscle fatigue in healthy untrained men

The muscle strength of the hamstrings decreased in PS (<i>p</i> = 0.039) and SS (<i>p</i> = 0.001) but did not change in TS (<i>p</i> = 0.434). Muscle strength of the quadriceps decreased in all interventions (<i>p</i> < 0.05). In all interventions, the training volume of the hamstrings decreased in Set 2 (<i>p</i> < 0.05), and that of the quadriceps decreased in Set 3 (<i>p</i> < 0.05). The total training volume in PS was higher than TS (<i>p</i> < 0.01) and SS (<i>p</i> = 0.03). Time efficiency in SS was higher than TS (<i>p</i> < 0.01) and PS (<i>p</i> < 0.01). These results indicated that PS could be useful for individuals with sufficient time for resistance training because of greater training volume, while SS could be useful for those with limited time due to better time efficiency.
