Abstract
Velocity Based Training (VBT) such as Perch Technology (PT) has been utilized to increase performance in velocity and power through motor learning feedback concepts of Knowledge of Results (KR) and Knowledge of Performance (KP). It is unknown which type of feedback mechanism is ideal for optimal performance. In tactical athletes, disparities between male and female performance on velocity and power in the trap bar deadlift event (TBDL) of the Army Combat Fitness Test (ACFT) have been identified in career soldiers and ROTC cadets. PURPOSE: To determine and quantify what effect feedback type may elicit on TBDL velocity and power in female ROTC cadets. METHODS: Participants (n=13) were randomly assigned to 1 of 4 groups: control group (CG) receiving no feedback and 3 feedback groups (KR, KP, KR+KP). Following an initial ACFT, 85lb TBDL was conducted for 5reps/3sets/2d/wk. All participants were instructed to lift as fast as possible. Velocity and power were measured utilizing PT. Following 6 weeks a final 3rep max TBDL was assessed. RESULTS: KR and CG significantly increased participants’ velocity (KR 6.6%, CG 5.6%, p = 0.03) and power (KR 6.6%, CG 5.4%, p = 0.04) in TBDL after 6 weeks of VBT. CONCLUSION: VBT results in participants increasing TBDL velocity and power, while feedback overload may adversely impact performance results.
