Abstract:
Purpose:Regular aerobic exercise has been recommended as an effective lifestyle strategy for the prevention and treatment of cardiovascular disease. However, it is unclear whether short-term exercise (＜ 6 weeks) can also improve vascular function. Thus, we sought to evaluate the efficacy of short-term spinning exercise to improve vascular function and body composition in young women.
Methods:Twelve young women (age, 22±2 years; body mass index, 22.2±3.3 kg/m 2 ) participated in 10 spinning exercise sessions (50 minutes per session including 5 minutes for warm up and cool down) at 60% to 85% age predicted maximal heart rate. Assessments were hemodynamics (heart rate [HR], rate-pressure product [RPP], brachial and central blood pressure) and vascular function (carotid to femoral pulse wave velocity [c-f PWV], augmentation index normalized to a HR of 75 beats [AIx@75], brachial artery flow-mediated dilation [FMD]), and body composition. All measurements were obtained at baseline before (test 1 [T1] and test 2 [T2]) and again after completion of the last spinning exercise session (test 3 [T3]).
Results:Short-term spinning exercise reduced c-f PWV (T1 : 6.2±0.7 m/sec, T3 : 5.7±0.6 m/sec, p=0.012), AIx@75 (T1: 2.4%±8.8%, T3: −5.9%±9.3%, p＜ 0.001) and increased brachial artery FMD (T1: 8.0%±4.0%, T3: 11.8%±5.4%, p=0.002). Percent body fat also decreased after short-term spinning exercise (T1 : 29.3%±6.0%, T3 : 28.4%±6.1%, p=0.011). In addition, all participants achieved 100% adherence.
Conclusion:These findings provide preliminary evidence for the effects of short-term spinning exercise to improve vascular function and body composition in young women.
