  Gender Differences in O2 Pulse During Single Set vs. Multiple-set Resistance Exercise                                 Nocera,VG., Meske, S., Mookerjee, S. Bloomsburg University, Bloomsburg, PA  Purpose: To compare O2 pulse in males and females during single and multiple set upper body resistance training. Methods: A total of 24 subjects (12 ♂, 12 ♀) mean age (±SD) 21.4 (±1.3) years, performed both a 1 and 3-set, 5-exercise, 10-repetition, upper body protocol (bench press, lat pulldown military press, biceps curl, triceps pushdown). Loads were set at 70% of their 1-repetition maximum using a lifting cadence of 15 reps· min-1. A minimum of 48 hours elapsed between testing sessions. Breath-by-breath data were recorded via a portable, telemetry metabolic measurement system. Results: Two-way repeated measures ANOVA was used to analyze differences between sets and genders. Data (mean ±SD) are presented in the table below:  Set # Bench Press  ♂       ♀ Lat Pulls  ♂       ♀ Military Press ♂       ♀ Tricep Press  ♂       ♀ Bicep Curl  ♂        ♀ 1- set Mn 6.41 4.96 8.78 4.83 8.71* 4.17 7.04* 3.72 6.95* 3.99 SD 3.53 2.84 4.94 2.60 4.98 2.25 3.26 2.07 3.85 2.04 3- set Mn 7.00 5.65 8.12 5.13 5.60 3.90 5.88 3.69 5.74# 3.89 SD 3.94 3.03 4.32 2.56 3.07 2.35 2.78 1.85 2.94 1.99 Sign. Diffs. (p<0.05) * between genders, # between sets  There were significant differences in O2 pulse between genders in the smaller muscle group exercises. Between single and 3 set differences were only seen in the males for the bicep curl exercise. Variations in O2 pulse during exercise represent changes in stroke volume and arterial-mixed venous O2 difference. Conclusion: The significantly higher O2 pulse recorded during the smaller muscle exercises were possibly due to increased sympathetic drive.
