Purpose: Regular aerobic exercise has been recommended as an effective lifestyle strategy for the prevention andtreatment of cardiovascular disease. However, it is unclear whether short-term exercise (£¼6 weeks) can also improvevascular function. Thus, we sought to evaluate the efficacy of short-term spinning exercise to improve vascularfunction and body composition in young women.
Methods: Twelve young women (age, 22¡¾2 years; body mass index, 22.2¡¾3.3 kg/m2) participated in 10 spinningexercise sessions (50 minutes per session including 5 minutes for warm up and cool down) at 60% to 85% agepredicted 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]), andbody composition. All measurements were obtained at baseline before (test 1 [T1] and test 2 [T2]) and again aftercompletion of the last spinning exercise session (test 3 [T3]).
Results: Short-term spinning exercise reduced c-f PWV (T1: 6.2¡¾0.7 m/sec, T3: 5.7¡¾0.6 m/sec, p=0.012), AIx@75(T1: 2.4%¡¾8.8%, T3: ?5.9%¡¾9.3%, p£¼0.001) and increased brachial artery FMD (T1: 8.0%¡¾4.0%, T3: 11.8%¡¾5.4%,p=0.002). Percent body fat also decreased after short-term spinning exercise (T1: 29.3%¡¾6.0%, T3: 28.4%¡¾6.1%,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 improvevascular function and body composition in young women.
