The linear force–velocity (F–V) relationship is frequently used to evaluate the maximal capacities of active muscles to produce force ( F 0 ), velocity ( V 0 ), and power (P max ) during a variety of tasks (vertical jump, bench press throw [BPT], isokinetic exercises, etc). 1 – 4 The F–V slope (ie

drops from a set height and upon landing performs a vertical jump at maximal effort. The drop jump can be broken into 2 distinct temporal phases: the contact phase, which can be further subdivided into landing time (T Land ) and push-off time (T Push ), and the flight phase, that is, time spent in the

NCAA Division I women’s basketball season demonstrated that more playing time during games enhanced lower body strength and power despite decreases in energy, focus, and alertness. 23 Similarly, greater playing time has been linked with enhanced vertical jump performance and improved feelings of
