Purpose: To determine the impact of inclusion of a Band or Chain Compensatory Acceleration Training 5-week training phase on maximal upper body strength during an off-season strength and conditioning program for collegiate male athletes.Patients and methods: Twenty-four NCAA collegiate baseball players who were familiar with the current strength and conditioning program and had a minimum of 1 year of formal collegiate strength and conditioning experience volunteered to participate in this study. None of the men had participated in compensatory acceleration training (CAT) before this study. Subjects were matched following a maximal effort (1-RM) bench press test then were randomly assigned into a band-based CAT group or a chain-based CAT group, and participated in a 5-week training phase... that including bench pressing twice per week. Upper body strength was measured by 1-RM bench press again at week 6. A 2 x 2 mixed factorial (method x time) analysis of variance was calculated to compare differences across groups. The alpha level was set at p < 0.05.Results: No difference (F1,22 = 0.04, p = 0.84) existed between Band CAT and Chain CAT groups. A significant difference was observed between pre- and post- tests of 1-RM bench (F1,22 = 88.46, p = 0.001).Conclusion: A 5-week Band CAT or Chain CAT training program used in conjunction with an off-season strength and conditioning program can increase maximal upper body strength in collegiate baseball athletes. Using Band CAT and/or Chain CAT as a training modality in the off-season will vary the training stimulus and help to maintain the athlete’s interest.
