Description
The critical velocity (CV) model identifies an athlete’s CV, analogous to their maximal aerobic steady state, and their anaerobic work capacity (D’). The CV concept is a technique for establishing the velocity-time (V-t) relationship of the severe exercise domain, where the D’ represents the finite capacity for work >CV. The 3-min all-out exercise test (3 MT) has emerged as a technique for estimating CV and D’. In soccer, there is a need for both an aerobic base (i.e., CV) along with an ability to sprint repetitively (i.e., D’). We have recently devised a 3 MT that readily identifies CV and D’ with GPS and can be used to prescribe interval training. We sought to adapt this test for indoor running using digitized video on 20 female, collegiate soccer players. We divided the team into two groups identified to improve deficiencies in either CV or D’, respectively. Each group completed seven interval training sessions over a four week period at identical percentages of depletions of D’ but at different V-t limit durations. For example, the group working to improve their D’ ran shorter intervals at higher velocities. Telemetry heart rate (HR) was recorded and downloaded from all athletes, and for each workout. The HR data from each workout achieved progressively higher values after each interval completed, a characteristic of individuals exercising above CV. Post assessment of the all-out test will be evaluated to determine the efficacy of the program.
