Changes in Body Composition with Six Weeks of Resistance Training Conference Paper uri icon


  • PurposeResistance exercise training has been shown to increase muscle mass. However, it is not as common to be recommended for fat loss. The purpose of this study was to examine the effects of 6week resistance exercise training on body composition.MethodEight untrained young men and women (Age=245, BMI=303) performed a 6week progressive whole body resistance training program, consisting of chest press, leg press, lat pulldown, leg curl, arm curl, leg extension and triceps extension. Dualenergy Xray absorptiometry (DEXA) was performed before and after training.ResultsAfter 6 weeks of resistance exercise training, lean mass significantly increased by 2.060.95% (54.553.03 to 55.83.39 kg, p=0.040), while body fat percentage significantly decreased by 5.051.33% (29.855.90 to 28.585.85 kg, p=0.013). There was no significant change in total body mass (87.666.64 to 87.636.64 kg, p=0.941).ConclusionSix weeks of resistance exercise training is sufficient to result in significant muscle gain and fat loss. While total body mass remained unchanged, body composition was improved. Therefore, resistance exercise may be recommended for the purpose of fat loss while improving muscle mass.
