BACKGROUND: This pilot study observed the effects of short duration interval training on anthropometric, body composition and resting metabolic rate (RMR) measurement changes in sedentary, overweight, middle-aged women over a 12-week period.
METHODS: Subjects (N.=9) were female volunteers (51.3±5.5 yr; 77.20±6.12 kg body wt; BMI=28.9±2.1 kg/m2; mean±SD) who exercised five out of seven days for 12 weeks. The exercise program (15.0±3.0 min) consisted of five different exercise routines which included total body, lower extremity, yoga, cardio and abdominal segments. Relative body fat (%BF) was measured via air displacement plethysmography (ADP), along with five anthropometric measurements and RMR (Vmax metabolic system) prior to and after 12 weeks. Dependent t-tests probed for significant differences at the P<0.05 level. Values are expressed as mean±standard deviation.
RESULTS: Four of the five pre-post anthropometric measurements were significantly reduced for abdomen, hips, waist and thigh (97.79+5.11 vs. 91.95+5.64; 104.90 +5.33 vs.100.84+5.33; 84.25+7.57 vs. 80.26+7.36; 62.99+5.08 vs.59.18+4.82 cm, respectively). Pre-post relative fat mass (FM) and fat-free mass (FFM) were not significantly different (42.0±3.7 vs. 40.6±4.6 %fat; 44.72+4.49 vs. 45.27+4.04 kg). Pre-post differences in body volume (BV) and body density (BD) were not significant (76.75+7.2 vs. 75.78+6.9 L and 1.0060+.0077 vs.1.0090 +.0096 kg/L), and body mass (BM) and (RMR) were also not significantly different (77.16±6.08 vs. 76.43.±6.17 kg; 1412.6±103.5 vs. 1363.6±121.1 kcal).
CONCLUSIONS: This work is supportive that short duration interval training contributes to significant anthropometric reductions, specific to the abdomen, hips, waist and thighs over a 12-week period, which is important to decrease chronic disease development. Keywords: sedentary women, short duration interval training, anthropometric and body composition measures and resting metabolic rate measurement changes.
