Abstract
The objective of this pilot study was to compare the effects of a high-intensity interval training (HIIT) and a moderate intensity continuous training (MICT) performed within a fitness center, on various health indices of 49 sedentary and moderately obese women (age 37 ± 7 years; BMI 32 ± 4 kg/m2) randomly assigned to supervised exercise on a cycle ergometer, 3 times/week, during 12 weeks, at 60% (MICT, n=24) or 85% (HIIT, n=25) of their heart rate reserve for weeks 5-12. Anthropometry, body composition, cardiorespiratory fitness, CRF (2 km-walking test estimated V;˙O2max), quality of life, QoL (SF-36 Questionnaire), eating behaviors (Three Factor Eating Questionnaire, TFEQ) and perceived health (Short Health Perceived Questionnaire, SHPQ) were obtained before and after training from 10 HIIT vs. 13 MICT participants who completed the program. At baseline, both groups showed similar characteristics, except for a better sleep quality (SHPQ) in MICT than in HIIT participants (p<0.005). Increases in CRF (+3 to +5%) and decreases in body weight (-2%) and thus BMI (-2.5 to -4.5%), waist girth (-4%) and fat mass (-6 to - 8%) were comparable (0.0001Keywords
