Abstract

The effects of 2 different weight training programs incorporating bench press (BP) and pullover (PO) exercises on swimming performance, power, enzyme activity, and fiber type distribution were studied on 16 men (age = 23 ± 4 years). A 30-second group (n = 6) performed up to 20 repetitions of BP and PO in 30 seconds. The 2-minute group (n = 6) performed a maximum of 80 repetitions of BP and PO in 2 minutes. As participants reached the prescribed 20 or 80 repetitions, the weight was increased 4.5 kg. A third group (n = 4) served as nontraining controls. Exercise groups trained 3 times per week for 6 weeks. Maximal effort swims of 50 and 200 yd were performed before and after training. Training resulted in increases in work on both exercises in both groups pre-to post-Training (BP 30 seconds, 722 ± 236- 895 ± 250 kg; PO 30 seconds, 586 ± 252-1,090 ± 677 kg; and BP 2 minutes, 1,530 ± 414-1,940 ± 296; PO 2 minutes, 1,212 ± 406-2,348 ± 194, p ≤ 0.05). Swim performances of the 30-second group improved for both the 50-yd (32.0 ± 6.9 seconds, 30.0 ± 5.9 seconds, p ≤ 0.05) and 200-yd swims 200.0 ± 54 seconds, 182 ± 45.1 seconds (p ≤ 0.05), whereas 2-minute training improved only the 200-yd swim (198.3 ± 32.3 seconds, 186.2 ± 32.2 seconds). No changes in swim performance were observed for the control group. Triceps muscle succinate dehydrogenase activities increased (pre 3.48 ± 1.1 mmol g-1 wet weight per minute, post 6.25 ± 1.5 mmoles g-1 wet weight per minute, p ≤ 0.05) in only the 30-second training group, whereas phosphofructokinase activities and fiber type distribution did not change in either training group. This study has demonstrated that a 30-second 20-repetition weight training program, specific to the swimming musculature without concurrent swim training, improves swimming performances at both 50-and 200-yd distances.
