A comparison of combined running and weight training with circuit weight training

Both programs of RUN-CWT and CWT were effective in improving measures of physical fitness and Statistically, one training program was not shown to be superior to the other.

Abstract

The purpose of this study was to compare the physiologic effects of a program of combined running and weight training (RUN-CWT) with a program of circuit weight training (CWT). Thirty-six females (X age = 35.7 yr) and 41 males (X age = 36.1 yr) were randomly assigned to RUN-CWT, CWT, and control groups. The training groups participated in 12-wk programs, 3 d . wk-1. Three circuits of 10 weight-training exercises were completed with 12-15 repetitions performed in 30 s at 40% of one-repetition maximum at each station. The 30-min RUN-CWT program included 30 s of running on an indoor track following each CWT station, whereas the 22.5 min CWT program included a 15-s rest period between stations. The RUN-CWT groups had a significant (+ 17%) increase in VO2max (females 30.5-35.7 ml . kg-1 . min-1 and males 39.7-46.3 ml . kg-1 . min-1) and strength (females + 24% and males +21%), and a significant decrease in body fat percentage (females -3.2% and males -4.1%). The CWT groups also increased significantly in VO2max (+12%) and strength (+17%) and decreased in body fat (-3.0%). The controls did not change significantly in any variable. Statistically, one training program was not shown to be superior to the other; thus, both programs of RUN-CWT and CWT were effective in improving measures of physical fitness.
