Notes
- Abstract:
- The dose of exercise required for successful weight loss is greater than the minimum amount of exercise recommended to improve health. Time constraints and risk of musculoskeletal injuries are two factors that make adherence to exercise difficult for the overweight and unfit person. One possible strategy for increasing the rate of caloric expenditure while walking without increasing the duration or intensity of exercise is to include upper-body exercise. We have found that using resistive arm exercise (waist belt with pull cords) raises energy expenditure by approximately 30% while walking. Purpose: The purpose of this study was to determine whether adding arm exercise while walking during an 8-week walking program would result in greater reductions in BMI and percent body fat (%BF) and an increase in O V 2max of overweight adults when compared to walking without arm exercise. Methods: Twenty-four participants (age: 39 ± 10 yr; mean ± SD) were randomly assigned to an experimental group (arm exercise + walking) and a control group (walking only). Training sessions were 30-50 min, 3-5 d/wk, progressing in duration and frequency over 8 wks. Walking intensity was set slightly below lactate threshold. Results: Arm exercise was performed on average 61 % of the time during the training sessions. While training improved O V 2max (30.5 ± 5.8 to 33.5 ± 7.0 vs 29.0 ± 5.8 to 32.1 ± 5.3 ml.kg-1.min-1) and reduced BMI (28.2 ± 2.1 to 27.9 ± 2.5 vs 29.9 ± 2.9 to 29.7 ± 3.1 kg.m-2) and %BF (30.7 ± 6.2 to 28.9 ± 6.5 vs 30.9 ± 6.9 to 30.2 ± 7.2) similarly in experimental and control groups (p < 0.05), respectively, there were no differences in group responses. CONCLUSION: The addition of resistive arm exercise to walking did not result in significant improvements in O V 2max, BMI or %BF despite the increased rate of energy expenditure during training.
