IJERPH, Vol. 18, Pages 10897: Effects of Regular Long-Term Circuit Training (Once per Week) on Cardiorespiratory Fitness in Previously Sedentary Adults International Journal of Environmental Research and Public Health doi: 10.3390/ijerph182010897 Authors: Verena Menz Hannes Gatterer Sachin B. Amin Reinhard Huber Martin Burtscher The purpose of the study was (1) to investigate the effects of regular long-term circuit training (once per week) on cardiorespiratory fitness (CRF) in sedentary adults and (2) to compare training progress with the effects of continued exercise participation by regularly active age-matched individuals. Ten sedentary, middle-aged (51 ± 6 years) individuals (sedentary group, SG) of both sexes performed 32 weeks (1 training session/week) of supervised circuit training and 10 weeks of self-managed training. Effects were compared to an age-matched group (51 ± 8 years; n = 10) of regularly active individuals (active group, AG). CRF (expressed as peak oxygen uptake: VO2peak; peak power output: PPO) and systemic blood pressure (BP) during the incremental test were measured at the start and after the training intervention. CRF decreased significantly within the AG (VO2peak: 43.1 ± 7.3 vs. 40.3 ± 6.5 mL/min/kg, p < 0.05; PPO: 3.3 ± 0.6 vs. 3.1 ± 0.6; p < 0.05) but was maintained in the SG. In addition, significant improvements in restoration of the oxygen level in leg muscles after exercise and reduced systolic BP (18...
