This study aimed to investigate the acute effect of high-intensity interval training (HIIT) and sprint interval training (SIT) on resistance training (RT) performance and their combined effect on lower-body neuromuscular capacities. The results showed that SIT had a greater impact on RT quality and F-0 capacity compared to long-interval HIIT.

Selective effect of different high-intensity running protocols on resistance training performance. J Strength Cond Res 37(6): e369-e375, 2023-This study aimed to explore the acute effect of 2 high-intensity running protocols (high-intensity interval training [HIIT] and sprint interval training [SIT]) on resistance training (RT) performance and their combined effect on the lower-body maximal neuromuscular capacities. Eighteen healthy subjects randomly completed 3 experimental protocols: only RT, HIIT + RT, and SIT + RT. Characteristics of the RT protocol include 3 back-squat sets of 10 repetitions or 20% velocity loss against 60% of 1 repetition maximum with 3 minutes of interset rest. Characteristics of the high-intensity running protocols include HIIT (4 intervals of 4 minutes at similar to 110% of functional threshold power with 3 minutes of interinterval rest) and SIT (6 all-out sprints of 30 seconds with 4 minutes and 24 seconds of interinterval rest). The force-velocity relationship (maximal values of force [F-0], velocity [v(0)], and power [P-max]) was evaluated at the beginning and at the end of each experimental protocol. The number of back-squat repetitions (p = 0.006; effect size [ES] = -0.96), fastest velocity (p = 0.003; ES = -0.63), and average velocity (p = 0.001; ES = -0.73) were lower for the SIT + RT protocol compared with the RT protocol, but no significant differences were observed between the RT and HIIT + RT (p >= T0.057; ES <=.-0.46, except -0.82 for the number of back-squat repetitions) and HIIT + RT and SIT + RT (p >= T0.091; ES .0-0.35) protocols. The 3 protocols induced comparable decreases in v(0) and P-max (F-(2,F-34) 2,0.96; p >= 0.393), but F-0 tended to decrease after the SIT + RT protocol and to increase after the RT and HIIT + RT protocols (F-(2,F-34) = 4.37; p = 0.035). Compared with RT alone, the data suggest that SIT deteriorates RT quality and F-0 capacity more than long-interval HIIT.
