Key result
Three weeks of moderate aerobic training improves lipids, body fat, and VO2 max in moderate-risk adults.
Why the study?
Cardiovascular diseases are a leading cause of death in India, with a high burden in young and middle-aged adults, necessitating evaluation of interventions to improve cardiovascular risk profiles in moderate risk asymptomatic individuals.
Does short-term (3 weeks) moderate intensity aerobic training improve cardiovascular risk profiles in asymptomatic adults with moderate risk factors?
RCT (n=34)
randomized
Does short-term (3 weeks) moderate intensity aerobic training improve cardiovascular risk profiles in asymptomatic adults with moderate risk factors?
A 3-week moderate intensity aerobic exercise program improves lipid profiles and aerobic capacity in asymptomatic adults with moderate cardiovascular risk.
Supports brief aerobic programs for risk reduction in moderate-risk adults; extends RCT evidence to 3-week interventions.
Background: According to World Health Report 2002, cardiovascular diseases (CVDs) will be the largest cause of death and disability by 2020 in India. In 2020, 2.6 million Indians are predicted to die due to coronary heart disease, which constitutes 54.1% of all CVD deaths. Nearly half of these deaths are likely to occur in young and middle-aged individuals (30-69 years). We undertook this study with objectives to evaluate the cardiovascular risk profile in asymptomatic individuals with moderate risk factors and to understand the effect of the short-term (3 weeks) exercise over cardiovascular risk factors. Materials and Methods: A randomized controlled trial was conducted with a total of 34 subjects comprising of 17 subjects in each group. Subjects underwent biochemical tests like fasting lipid (total cholesterol [TC], triglyceride, high-density lipoproteins [HDLs], low-density lipoproteins [LDLs]) and fasting blood glucose. Other outcome measures were VO 2 max, body mass index and body fat % (BF%). Results: This study suggested that 3 weeks of moderate intensity aerobic training has a beneficial effect in lowering the cardiovascular risk profiles in adults with moderate risk factors. This training reduced TC, improves HDL, reduced LDL and improved aerobic capacity by improving VO 2 max and reducing BF%.

Singh et al. (2015) conducted an RCT in Moderate cardiovascular risk (n=34). Moderate intensity aerobic training vs. Control was evaluated on Cardiovascular risk profile (fasting lipids, fasting blood glucose, VO2 max, BMI, and body fat %). A 3-week moderate intensity aerobic training program reduced total cholesterol, LDL, and body fat percentage, and improved HDL and VO2 max in adults with moderate cardiovascular risk factors.
