Key result
Short-term spinning exercise improves vascular function in young women, reducing PWV by ~8%.
Why the study?
Regular aerobic exercise prevents cardiovascular disease, but whether short-term exercise (< 6 weeks) can also improve vascular function remains unclear.
Does short-term spinning exercise improve vascular function and body composition in young women?
Does short-term spinning exercise improve vascular function and body composition in young women?
Short-term spinning exercise (10 sessions) significantly improves vascular function and reduces body fat in young women.
Spinning exercise was associated with better vascular function in young women; hypothesis-generating and needs randomized confirmation before practice change.
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±3.3kg/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 [T 3 ]).Results: Short-term spinning exercise reduced c-f PWV (T 1 : 6.2±0.7 m/sec, T 3 : 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 (T 1 : 29.3%±6.0%,T 3 : 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.

Kim et al. (2022) studied Healthy (n=12). Short-term spinning exercise vs. Baseline (1-week time control period) was evaluated on Carotid to femoral pulse wave velocity (c-f PWV) (p=0.012). Short-term spinning exercise significantly improved vascular function in young women, reducing carotid-femoral pulse wave velocity from 6.2 to 5.7 m/sec and increasing flow-mediated dilation from 8.0% to 11.8%.
