Purpose: We examined the impact that cycle ergometry exercise had on percent body fat (%BF) estimates when assessed using either leg-to-leg or segmental bioelectrical impedance analysis (LBIA; SBIA) and whether the intensity of the exercise bout impacts the %BF magnitude of change. Method: Seventy-four college-aged adults participated in this study. Participants visited the laboratory on three separate occasions. Testing included two 30-min exercise sessions (70% HR[subscript max] and 85% HR[subscript max]) and a 30-min no-exercise session, which served as the control. Results: Following exercise, significant ("p" less than 0.05) reductions in mean %BF were observed when using LBIA (70% HR[subscript max] = 0.3%; 85% HR[subscript max] = 0.5%) and SBIA (70% HR[subscript max] = 0.8%; 85% HR[subscript max] = 1.4%). The mean %BF reductions were significantly ("p" less than 0.04) greater following exercise at the higher intensity for both analyzers. Conclusions: Our findings indicate that cycle exercise performed before LBIA and SBIA body composition assessment reduces mean %BF estimates. In addition, the %BF reductions were found to be larger at the higher end of the American College of Sports Medicine/American Heart Association recommended intensity range (85% HR[subscript max]) and when the SBIA analyzer was used to conduct the assessment.
