Resistance training (RT) is a powerful systemic stimulus known to improve a multitude of physiological variables. These include but are not limited to musculoskeletal strength, power, muscle mass, bone mass, and connective tissue. The sport of track and field is composed of many different events that focus on strength, power, and muscular endurance. Thus, resistance training is typically a vital part of athletic preparation for track and field athletes. PURPOSE: The purpose of this study was to investigate specific manipulations of the acute program variables within the context of an off-season resistance training program. METHODS: 34 male NCAA Division I track and field student-athletes (age: 20.3 ± 1.9 y; body mass: 83.9 ± 11.1 kg) participated in 12 weeks of a non-linear periodized training program between the months of September and December. Groups were separated by athletic event and thus, performance goals (Group 1: n=12, age: 20.1±1.10, body mass: 87.8±13.3 kg; Group 2: n=12, age: 21.1±1.10, body mass: 82.9±10.4 kg; Group 3: n=10, age: 18.9±0.8, body mass: 80.4±8.1 kg). The training groups prioritized training for power, local muscular endurance, and general strength, respectively. Performance variables were assessed at the beginning and end of this training program and consisted of counter movement vertical jump with arm swing (CMVJ), 1-repetition-maximum (1RM) in the barbell bench press, and barbell back squat. RESULTS: The primary findings of this investigation are Group 1 saw significant (p≤0.05) statistical increases in vertical jump (4.4±.1 cm), and back squat maximum (13.1±3.6 kg). Group 2 saw significant (p≤0.05) statistical increases in bench press maximum (14.2±0.5 kg), and back squat maximum (15.0±0.6 kg). Group 3 saw significant (p≤0.05) statistical increases in vertical jump (4.7±0.7 cm) and maximum back squat (20.0±5.0 kg). Our data indicate that the prioritization of strength within a 12 week off-season training program had the best overall effect on the performance variables.
