Effects of simultaneous training for strength and endurance on upper and lower body strength and running performance.

摘要: This study examined simultaneous training for strength and endurance during a 13-week, 3-day week program of hydraulic resistive circuit running. Eighteen college males (U.S. Army ROTC) were placed into low resistance (LR; n = 10) or high (HR; 8) groups, 10 controls did not train. There 20 exercise stations (7 upper lower body, 6 supplementary). LR HR performed 2 circuits with work/rest ratio to 40 s the min workout. trained at two resistances (approximately 100 cm.s-1), while higher 50 cm.s-1). Following workout, subjects ran miles. Pre post tests included strength, physical fitness, anthropometry. Strength was assessed (1) dynamometry 4 exercises speeds using computerized dynamometer (Hydra-Fitness, Belton, TX); (2) isokinetic isotonic upright squat supine bench press Ariel Exerciser (Trabuco Canyon, CA); (3) concentric eccentric arm flexion/extension 60 120 degrees.s-1 on Biodex (Shirley, NY), (4) 1-RM free weight flexion extension. The fitness 2-mile run, sit-ups, push-ups. Anthropometry 3 fatfolds, girths, leg volume. no significant changes in body composition interactions between test measures groups (p greater than 0.05). Improvements averaged 15% (run time), 30% (push-ups), 19% (sit-ups; p less Significant improvements also occurred 8 testing (overall change 8.8%), (9.4%), (6%), but (1.9%). overall 6.5% compared 16% prior that used without concomitant We conclude gains somewhat compromised by run training, performance independent intensity.
