Effects of strength training and combined physical training in women with coronary artery disease: a systematic review and meta-analysis
摘要
To perform a systematic review of the literature investigating the effects of strength training (ST) and combined training (CT—strength and aerobic) on physical performance and cardiorespiratory responses in women with CAD.
MethodsSearches were conducted in the PubMed, Cochrane, Web of Science, Scopus, SportDiscus, Embase, and ProQuest databases. The inclusion criteria were randomized and non-randomized clinical trials that applied ST or CT and provided data on strength outcomes in women with CAD. Data analysis was performed descriptively, quantitatively, and through meta-analyses. The results were presented in tables and figures with the aid of the Stata 16.1 software.
ResultsNine studies met the inclusion criteria (five hundred twenty-five participants). For cardiorespiratory fitness, the pooled analysis indicated no significant improvement in VO2peak (MD: − 0.75 ml/kg/min; 95% CI − 2.18 to 0.68; I2 = 0%, p = 0.30) compared to control groups. However, the analysis of physical performance outcomes revealed gains in upper limb strength (bench press—MD: 8.99; 95% CI 1.85–16.14; I2 = 88.4%, p = 0.01; shoulder press with free weights—MD: 5.73; 95% CI 2.78–8.68; I2 = 0%, p < 0.001). Positive effects were also found in lower limb performance (knee extension—MD: 2.56; 95% CI − 0.87 to 5.98); I2 = 0%, p = 0.14).
ConclusionImprovements in strength were found following ST and CT protocols, with beneficial effects on the health of women with coronary artery disease. Although the point estimate with regards to cardiorespiratory variables favored the control group, the evidence remains insufficient to confirm a significant difference.
