The capacity to rapidly generate and apply a great amount of force seems play key role in sprint running. However, it has recently been shown that, for sprinters, the technical ability effectively orient onto ground is more important than its total amount. force-vector theory proposed guide coaches selecting most adequate exercises comprehensively develop neuromechanical qualities related distinct phases sprinting. This study aimed compare relationships between vertically-directed (loaded unloaded vertical jumps, half-squat) horizontally-directed (hip-thrust) performance top-level track field athletes. Sixteen sprinters jumpers (including three Olympic athletes) executed loaded jump squats hip-thrusts, sprinting speed tests at 10-, 20-, 40-, 60-, 100-, 150-m. Results indicated that hip-thrust associated with maximum acceleration phase (i.e., from zero 10-m; r = 0.93), whereas jumps seem be top-speed distances superior 40-m; varying 0.88 0.96). These findings reinforce mechanical concepts supporting theory, provide sport scientists valuable information about potential use benefits using vertically- or horizontally-based training exercises.
