PURPOSE: To compare the effectiveness of high-intensity aerobic interval training
(AIT) with active recovery and continuous moderate-intensity exercise (CME) on
exercise capacity and metabolic risk factors in adults with cardiometabolic
disorders through a systematic review and meta-analysis. METHODS: Studies were
selected from 5 electronic databases (PubMed, MEDLINE, CINAHL, Physiotherapy
Evidence Database [PEDro] and Cochrane Library Register of Controlled Trials).
Randomized controlled trials (RCTs), published in English, that compared the
effects of AIT with CME on exercise capacity and metabolic risk factors in adults
with cardiometabolic disorders were included.
Aerobic interval training was
defined as high-intensity training separated by active recovery periods; CME
incurred identical energy expenditure as AIT. Each trial was evaluated using the
PEDro scale. Weighted mean difference (WMD) and 95% CIs were used to determine
the effect size for each outcome. RESULTS: Six RCTs with 153 participants (40
overweight/obesity, 19 with metabolic syndrome, and 94 with heart disease) were
included. The mean value on the PEDro scale for these studies was 5.0. Aerobic
interval training significantly increased peak oxygen consumption (WMD, 3.6
mL.kg.min; 95% CI, 2.3-4.9) with a trend of decreasing fasting glucose (WMD, -0.4
mmol/L; 95% CI, -0.9 to 0.2, P = .18) compared with CME.
The effects on other
metabolic risk factors were similar between AIT and CME. CONCLUSION: Analysis of
a limited number of studies with small sample sizes indicates that AIT is superior to CME in terms of improving exercise capacity. Further high quality
studies with larger sample size are required to confirm this finding in adults
with cardiometabolic disorders.
