Concurrent Validity and Reliability of Different Technologies for Sprint-Derived Horizontal Force-Velocity-Power Profiling

Abstract: Cormier, P, Tsai, M-C, Meylan, C, Agar-Newman, D, Epp-Stobbe, A, Kalthoff, Z, and Klimstra, M. Concurrent validity and reliability of different technologies for sprint-derived horizontal force-velocity-power profiling. J Strength Cond Res 37(6): 1298–1305, 2023—This study evaluated the validity and reliability of common systems to assess sprint-derived horizontal force-velocity-power (FVPH) profile metrics. Two double constellation athlete monitoring systems (STATSports Apex, Catapult Vector S7) and one timing… Show more

“…Nagahara et al (46) identified that lower sampling rates (<10 Hz) resulted in poor agreement, with some profiling metrics with sampling rates ≥10 Hz providing superior agreement and reliability. More recent studies have since shown improvements in agreement outcomes (CVs <5%) across metrics with improved intrasystem and intersystem reliability using 10 Hz GNSSs (11,14,22). Although measures of speed are achieving good agreement with higher sampling rates, present results suggest that GNSS is still suboptimal for quantifying acceleration metrics (21,58).…”

“…As acceleration is the rate of change in velocity, limitations in adequate sample rate will have implications for calculation of accurate acceleration. This can be observed in technology such as timing gates where low temporal resolution during the initial portion of the sprint will tend to overestimate F 0 in sprint modeling studies (14). As shown in Figure 3, both intertrial and intrasystem values for all metrics improve with increased sampling rates.…”
