Summary The aim of this study was to compare the effect of a cycling training programme performed at intensity corresponding to the lowest value of the respiratory quotient ( RQ ) versus at intensity corresponding to the ventilatory threshold ( VT ), on body composition and health‐related parameters in overweight women. Thirty‐two sedentary obese women (27–42 years old) were studied in a randomized trial of either RQ ( n = 17) or VT ( n = 15). RQ and VT training sessions were equalized by time (60 min) and performed in a cycloergometer. Anthropometry, body composition, lipid profile, glucose, basal metabolic rate (BMR) and fitness (maximal oxygen uptake) were evaluated before and after 12 weeks of intervention. Body weight, body mass index, fatness and fitness were improved in both groups ( P <0·001). Triglycerides (TG) levels decreased only in response to RQ ( P <0·001) and fat‐free mass (FFM) to VT ( P = 0·002). No differences were observed between groups. Both exercise intensities seem to be effective for improving health in overweight women. However, low‐intensity compared with the high‐intensity exercise training appears to have additional benefits on TG levels and to maintenance of FFM.
