- Description: Physical performance and electromyographic responses to an acute bout of paired set strength training versus traditional strength training. J Strength Cond Res 24(5): 1237-1245, 2010-The objective of this study was to investigate the acute effects of performing paired set (PS) vs. traditional set (TS) training over 3 consecutive sets on volume load (VL) and electromyographic (EMG) activity of the pectoralis major, anterior deltoid, latissimus dorsi, and trapezius muscles. Following a familiarization session 16 trained males performed 2 testing protocols using 4 repetition maximum loads: TS (3 sets of bench pull [Bpull] followed by 3 sets of bench press [Bpress] performed in approximately 20 minutes) or PS (3 sets of Bpull and 3 sets of Bpress performed in an alternating manner in approximately 10 minutes). Bpull and Bpress VL decreased significantly from set 1 to set 2 and from set 2 to set 3 under both conditions. There was no difference between VL per set, or over the sessions, between the 2 conditions. PS was determined to be more efficient (VL/time) as compared to TS. EMG activity of the 4 monitored muscles was not different for the 2 conditions or within each condition over the 3 sets. However, there was a significant within-set response in EMG activity in the Bpress exercise. The data suggest that a 4-minute rest interval between sets may not be adequate to maintain VL using either protocol. The data further suggest that PS training may be as effective as TS training in terms of VL maintenance and more effective in terms of efficiency. The comparison of EMG activity between the PS and TS protocols suggests that the level of neuromuscular fatigue does not differ under the 2 conditions. PS training would appear to be an effective method of exercise with respect to VL maintenance and efficiency.

- Description: The effect of a complex agonist and antagonist resistance training protocol on volume load and power output, electromyographic responses, and efficiency. J Strength Cond Res 24(7): 17821789, 2010-The objective of this study was to investigate the acute effects of performing traditional set (TS) vs. complex set (CS) agonist-antagonist training over 3 consecutive sets, on bench press throw (BPT) throw height (TH), peak velocity (PV), peak power (PP), bench pull volume load (VL), and electromyographic (EMG) activity. Eighteen trained men performed 2 testing protocols: TS comprising 3 sets of Bpull followed by 3 sets of BPT performed in approximately 20 minutes or CS comprising 3 sets of both Bpull and BPT performed in an alternating manner in approximately 10 minutes. Throw height, PV, PP, and EMG activity were not different within, or between, the 2 conditions. Bench pull VL decreased significantly from set 1 to sets 2 and 3, un! der both conditions. Decreases from set 1 to set 2 were 14.55 +/- 26.11 and 9.07 +/- 13.89% and from set 1 to set 3 were 16.87 +/- 29.90 and 14.17 +/- 18.37% under CS and TS, respectively. There was no difference in VL per set, or session, between the conditions. Although there was no augmentation of the power measures, CS was determined to have approximately twice the efficiency (ouput/time) as compared to TS. Efficiency calculations for VL, TH, PV, and PP are 103.47 kg.min(-1), 26.25 cm.min(-1), 1.98 m.s(-1).min(-1), 890.39 W.min(-1) under CS and 54.71 kg.min(-1), 13.02 cm.min(-1), 0.99 m.s(-1).min(-1), 459.28 W.min(-1) under TS. Comparison of EMG activity between the protocols suggests the level of neuromuscular fatigue did not differ under the 2 conditions. Complex set training would appear to be an effective method of exercise with respect to efficiency and the maintenance of TH, PV, PP, and VL.

- Description: The objective of this study was to examine the chronic effects on strength and power of performing complex versus traditional set training over eight weeks. Fifteen trained males were assessed for throw height, peak velocity, and peak power in the bench press throw and one-repetition maximum (1-RM) in the bench press and bench pull exercises, before and after the eight-week programme. The traditional set group performed the pulling before the pushing exercise sets, whereas the complex set group alternated pulling and pushing sets. The complex set training sessions were completed in approximately half the time. Electromyographic (EMG) activity was monitored during both test sessions in an attempt to determine if it was affected as a result of the training programme. Although there were no differences in the dependent variables between the two conditions, bench pull and bench press 1-RM increased significantly under the complex set condition and peak power increased significantly under the traditional set condition. Effect size statistics suggested that the complex set was more time-efficient than the traditional set condition with respect to development of 1-RM bench pull and bench press, peak velocity and peak power. The EMG activity was not affected. Complex set training would appear to be an effective method of exercise with respect to efficiency and strength development.
