Acute neuromuscular fatigue in circuit strength training: effects of varying work-to-rest durations
A significant reduction in MPV was observed following all protocols, indicating the presence of acute neuromuscular fatigue regardless of interval duration. Although no statistically significant differences in fatigue magnitude were detected between protocols, work-to-rest interval duration influenced repetition output and execution characteristics, with the 30:30 protocol allowing greater repetition volume compared with the 10:10 and 20:20 protocols.
