Method: 36 participants (28.19 ±5.30 yr; 168.50±8.93 cm; 66.33 ± 14.17 kg) were randomly assigned to three groups: machine circuit training group (MCT, n=12), dumbbell circuit training group (DCT, n=12), and control group (n=12). MCT and DCT participated in 8-weeks circuit training, three times per week, 25-30min. Body composition, strength, muscular endurance, flexibility, and cardiopulmonary endurance were examined pre and post intervention for all subjects. One-way ANCOVA and least significant difference (LSD) were used for the analysis. Significant level was set at α=.05. Results: There were no significant difference in body mass, body mass index, and fat free mass (p=.12; p=.17; p=.21) before and after 8-wk intervention in any group. Changes in skeletal muscle mass (MCT: +3.44%; DCT: +4.67%), percent body fat (MCT: -6.54%; DCT: -6.70%), and fat tissue mass (MCT: -8.75%; DCT: -7.85%) did not show any difference between MCT and DCT. Both training groups demonstrated significant difference with control group (p<.05). All fitness variables in MCT and DCT were improved significantly compared to control group (p<.05), chest press (MCT: +23.30%; DCT: +22.88%), leg press (MCT: +18.15%; DCT: +15.50%), 1-min push-ups (MCT: +18.86%; DCT: +16.29%), 1-min sit-ups (MCT: +9.43%; DCT: +11.30%) and predicted maximum oxygen uptake (MCT: +13.79%; DCT: +16.03%). No Differences were founded between MCT and DCT. Conclusion: The findings of present study confirmed the effectiveness of 8-wk circuit resistance training on body composition and fitness for sedentary healthy adults. Training effects was equivalent using machine or dumbbell as equipment.
