Abstract
Introduction: Physiological and psychological recovery, i.e., the balance between fatigue/stress and recovery and evaluated through heart rate variability (HRV), is essential for the good performance of athletes in all their activities. Cold water immersion (CWI) has been shown to reduce the negative effects of fatigue/stress by inducing physiological and biochemical changes that promote faster recovery. This study aims to analyze the scientific literature on the effects of CWI on post-exercise recovery, as measured by HRV in athletes.
Methods: A systematic review of randomized clinical trials (RCTs) was conducted following PRISMA guidelines. Databases such as Scopus, Web of Science, and MEDLINE were included it. The risk of bias of each study selected was assessed using Cochrane's guidelines for RCT.
Results: Twelve articles were included. All studies reported parasympathetic reactivation with CWI after physical exertion. Six studies demonstrated statistically significant results (p < 0.05) compared to a passive recovery, while eight studies reported moderate to large effect sizes.
Conclusion: The results of this study indicate that CWI after exercise may have a positive acute effect on parasympathetic reactivation, as measured by HRV.
期刊介绍：
Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
