Abstract (300 words maximum)
High intensity functional training (HIFT) workouts often challenge trainees to complete workloads as fast as possible. Although some studies have identified absolute pacing as a metric of HIFT intensity, none have viewed it as a relative measure, nor have comparisons been made between it and more traditional forms of describing intensity. Our purpose was to relate relative pace employed for each exercise and round of low- (LV) and high-volume (HV) versions of the same HIFT circuit with relative strength and muscle endurance. Nineteen experienced men and women (26.7±7.6 years; 173±8cm; 79.3±11.2kg) completed one baseline and two randomized experimental visits. Baseline assessments included one-repetition maximum (1-RM) power clean and RM toes-to-bar (TTB) and wall ball shots (WB). Experimental visits had participants complete five repetitions of PC (men=52.2kg; women=34.0kg), TTB and WB as fast as possible, as well as one round (RD) of either a LV (5xPC, 10xTTB, 15xWB) or HV (10xPC, 15xTTB, 20xWB) workout to determine maximal pace in each. Participants then completed five rounds of LV or HV for time. Pearson correlation coefficients were used to determine relationships between traditional measures of intensity and intensity based on pace for LV and HV. Positive relationships (p<0.001) were observed with TTB performance (between %RM and % max pace) during both workouts (r =0.76–0.77). The % max RD pace was related to both %RM of TTB (r =0.68, p <0.001) and WB (r =0.65, p =0.002) during LV, but only to WB (r =0.55, p =0.016) during HV. Average relative TTB pace was related to the number of repetitions prescribed to TTB and WB, relative to the individual’s endurance in each for both LV and HV. WB endurance was also related to RD pace in both workout volumes, whereas TTB endurance was only related to RD pace during LV.
