The Acute Effects of Manual Resistance on Ballistic Bench Press Performance

Matthew Paul Gonzalez, University of Texas at El Paso


Heavy conditioning activities (CA) during warm-ups has been found to improve subsequent movements. However, a problem with heavy CAs is the need for specialized equipment. Manual Resistance (MR) is accommodating resistance in which traditional exercises are replicated using resistance from a partner. This modality has led to improved muscular strength and endurance; however, the acute effects of MR have not been examined. Purpose: The purpose of this study was to determine if MR can lead to improvements in ballistic bench press (BBP) performance. Methods: Two subjects (age = 22.50 ± 0.71 years, weight = 97.88 ± 43.95 kg, BMI = 28.43 ± 10.05) attended nine sessions. One maximal strength session in which a one repetition maximum bench press was conducted, followed by four familiarization sessions, and four testing sessions. These consisted of performing three repetitions of BBP following a general warm up (baseline) and three repetitions of BBP after either a rest period (Baseline), a CA of manual resistance (MRC), and a CA of bench press (HBP) (post-CA measurements). During each BBP repetition, peak force, rate of force development, power, and electromyography (EMG) activation of the pectoralis major and triceps brachii were measured. Results: There was no statistically significant difference between the pre and post CA measurements, nor between the baseline, MRC, and HBP conditions. Conclusion: MR was not able to improve BBP performance, further research is needed with a larger sample size to determine if MR can lead to acute improvements in BBP performance.
