Objective To systematically review the efficacy of Nordic walking (NW) on exercise capacity and quality of life in patients with heart disease.
Methods PubMed, The Cochrane Library, Web of Science, EMbase, CINHAL, MEDLINE, CNKI, WanFang Data, VIP and SinoMed databases were electronically searched for randomized controlled trials (RCTs) on effect of NW in patients with heart disease from inception to March, 2022. Strict quality evaluation and data extraction were carried out for the included literature, RevMan 5.3 was used to perform a Meta analysis.
Results A total of 8 RCTs were included, with 459 subjects in total. The results of Meta-analysis showed that NW could increase 6 min walking distance (6MWD)MD=26.43, 95%CI, 7.81 to 45.04, P < 0.01 and metabolic equivalent (MET)MD=0.60, 95%CI, 0.19 to 1.01, P < 0.01 compared with conventional cardiovascular rehabilitation. However, there were no significant differences in quality of life score (physical and psychological scores in SF-36 Scale), peak oxygen uptake, anxiety score and depression score compared with traditional cardiac rehabilitation (P>0.05).
Conclusion Cardiac rehabilitation measures based on NW can increase the exercise intensity and improve the exercise ability of patients with heart disease compared to conventional cardiovascular rehabilitation. Due to limited quality and quantity of the included studies, higher quality studies are required to verify above conclusion.
