Background: Childhood obesity has negative impact on heart-rate variability (HRV) and, thereby, on the cardiovascular health of children and adolescents. Thus, physical-exercise interventions were proposed to increase HRV. The present systematic review aims to provide an up-to-date analysis of research on the effect of physical-exercise interventions on HRV in obese children and adolescents. Methods: An electronic search of the literature was performed, and 10 articles were included. PRISMA guideline methodology was employed. Results: Physical-exercise interventions predominantly involved aerobic training; however, alternative training programs, including judo or recreational soccer, were found. The duration of intervention ranged from 6 to 24 weeks, with a training frequency of between 2 and 7 times per week. The duration of sessions typically ranged from 40 to 60 min. Conclusions: Results of the included articles indicated that physical-exercise intervention increased the HRV and thereby the autonomic modulation of obese children and adolescents. This is significant, as HRV is associated with cardiovascular health. Such physical-exercise interventions are crucial to reduce weight and improve cardiovascular health in children and adolescents, thereby achieving a sustainable future.

Introduction: Heart rate variability (HRV), the beat-to-beat variation of adjacent heartbeats, is an indicator of the function of the autonomic nervous system (ANS). Increased HRV reflects well-functioning of autonomic control mechanism and cardiovascular health. The aim of this systematic review is to provide a systematic overview of the effects of different physical training modalities on resting HRV and cardiovascular health and risk factors (i.e., baroreflex sensitivity, body fat, body mass, body mass index, blood pressure, heart rate recovery, VO2 max, and VO2 peak) in young and middle-aged (mean age of the studies samples up to 44 years), healthy adults.Methods: A systematic review in accordance with the PRISMA guidelines was performed. Studies investigating the effects of different physical interventions (endurance, resistance, high-intensity, coordinative, or multimodal training) on HRV were included. Trials were considered eligible if the intervention lasted for at least 4 weeks and participants were regarded as general healthy. Five electronic databases were searched from 2005 to September 8th, 2020. The methodological quality of eligible studies was assessed by two study quality and reporting assessment scales (TESTEX and STARDHRV). PROSPERO registration number: CRD42020206606.Results: Of 3,991 retrieved records, 26 were considered eligible and analyzed. Twelve studies used an endurance training (of which three included high-intensity sessions), six studies resistance training, four studies coordinative training, two studies high-intensity training, and two studies used a multimodal intervention. Overall, the results showed for all types of intervention an improvement in linear and non-linear HRV parameters and cardiovascular health and risk factors. However, quality assessment revealed some methodological and reporting deficits.Conclusion: This systematic review highlights the benefits of different types of physical training interventions on autonomic function and health parameters in young and middle-aged, healthy adults. In conclusion, higher training intensities and frequencies are more likely to improve HRV. For future studies, we recommend adhering to the criteria of methodological standards of exercise interventions and HRV measurements and encourage the use of non-linear HRV parameters.

ObjectivesDetermine both the effects and hierarchy of effectiveness for exercise interventions (aerobic, strength training or both) on selected measures of adiposity (body mass index (BMI) in kg/m2, fat mass and per cent body fat) in overweight and obese children and adolescents.DesignNetwork meta-analysis of randomised exercise intervention trials.SettingAny setting where a randomised trial could be conducted.ParticipantsOverweight and obese male and/or female children and adolescents 2–18 years of age.InterventionsRandomised exercise intervention trials>4 weeks, published between 1 January 1973 and 22 August 2018, and which included direct and/or indirect evidence for aerobic, strength training or combined aerobic and strength training.Primary outcomesChanges in BMI in kg/m2, fat mass and per cent body fat.ResultsFifty-seven studies representing 127 groups (73 exercise, 54 control) and 2792 participants (1667 exercise, 1125 control) met the criteria for inclusion. Length of training (X- ± SD) averaged 14.1±6.2 weeks, frequency, 3.3±1.1 days per week and duration 42.0±21.0 min per session. Significant and clinically important reductions in BMI, fat mass and per cent body fat were observed in aerobic versus control comparisons (BMI, mean, 95% CI -1.0, 1.4 to −0.6; fat mass -2.1, –3.3 to −1.0 kg; per cent fat -1.5, –2.2 to −0.9%) and combined aerobic and strength versus control comparisons (BMI -0.7, –1.4 to −0.1; fat mass -2.5, –4.1 to −1.0 kg; per cent fat, -2.2, –3.2 to −1.2%). A significant reduction in per cent fat was also found for strength vs control comparisons (-1.3,–2.5 to −0.1%). Combined aerobic and strength training was ranked first for improving both fat mass (kg) and per cent body fat while aerobic exercise was ranked first for improving BMI.ConclusionsAerobic and combined aerobic and strength training are associated with improvements in adiposity outcomes in overweight and obese children and adolescents.PROSPERO registration numberCRD42017073103.

Background: Sedentary lifestyles are increasingly common amongst children, and insufficient physical activity is a global epidemic estimated to contribute to future incapacities and potential deaths. Objective: We aimed to increase the amount of evidence concerning the effect of chronic exposure to exercise on heart rate variability in children and adolescents affected by obesity. Methods: A systematic review commenced following the PRISMA guidelines developed by Web of Science, Virtual Health Library, PubMed, Cochrane Library, Embase, Ovid, Medline Complete, and Scopus using keywords obtained from the Descriptors in Health Sciences and Medical Subject Headlines (MeSH) terms. We considered (1) Population: Pediatric individuals affected by obesity; (2) Intervention: Exercise; (3) Control: Pre-intervention and sedentary; (4) Outcomes: Clearly presented primary parameters; and (5) Studies: Clinical trials, case controls, case reports, and case series. Results: 11 articles were involved and predominantly included procedures observed during approximately 12 weeks with a distribution of three sessions per week, each session being 30–60 min of aerobic exercise; additionally, the exercise grades were typically completed at a percentage of subjects’ maximum heart rates. The meta-analyses displayed a significant effect on the domains of time (R-R interval, SDNN, rMSSD), frequency (HF ms2, HF (n.u.), LF/HF), and the non-linear index (SD1). Conclusion: Chronic exposure to exercise influences heart rate variability in children and adolescents affected by obesity by elevating the variability and parasympathetic activity and improving the sympathetic-vagal balance. Exercises should be recommended for the improvement of cardiac autonomic modulation to prevent the likelihood of further chronic diseases.

Cardiotoxicity as a result of cancer treatment contributes to autonomic dysfunction and decreased cardiorespiratory fitness among cancer survivors. These deleterious cardiovascular outcomes reduce the survival prognosis for cancer patients and contribute to poor quality of life among survivors. Exercise interventions have been shown as effective in mitigating treatment-related side effects. However, previously published interventions have not explored the potential for improvement in autonomic dysfunction (heart rate variability, HRV). This study examined cardiovascular adaptations in cancer survivors (n = 76) who participated in a 26-week intervention consisting of combined aerobic and resistance training (CART). The most noteworthy improvements occurred during the first 13 weeks of training and were maintained throughout the end of the 26-week period. HRrest improved from baseline (PRE) to the midpoint (MID) ( P = .036) and from PRE to POST timepoints ( P = .029). HRV and VO2max did not initially appear to change in response to CART. However, after stratification on time since treatment, participants who were 5 or more years from their last treatment experienced improvements (ie increase) in the HRV characteristic of HF power ( P = .050) and also in VO2max ( P =.043), when compared to those experiencing less than 5 years of time since their last treatment. These findings highlight a need for more attention to address the cardiorespiratory deficits experienced by those who have recently completed cancer treatment. In conclusion, the CART intervention is effective in improving cardiorespiratory fitness and autonomic dysfunction. The structure of the intervention is feasible for cancer survivors to continue with at home, using minimal resources, and without supervision. This at-home model may be even more acceptable to recent survivors that may be homebound immediately following treatment.

Introduction: Heart rate variability (HRV) is negatively associated with mortality. Decrease in HRV is common in cancer patients. The association between HRV and general survival in cancer patients has made HRV a valuable biomarker for evaluation of the disease prognosis. Exercise is considered an interventional strategy to improve various outcomes in cancer patients. The present paper provides a descriptive review of the literature regarding the effect of exercise interventions on HRV in cancer patients. Methods: A systematic search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines in PubMed and Google Scholar, from inception since 1950 till October 15, 2018. The terms exercise, training, cancer, neoplasms, heart rate variability, and HRV were used in the search. Eligible studies were those trials using structured exercise intervention and having untrained adult cancer patients. Only English-language papers were included in the review. Results: Eight studies were included in the review. Of the various HRV parameters, 2 in the time domain (SDNN and RMSSD) and 3 in the frequency domain (LF, HF, and LF/HF) were commonly reported in the studies. Exercise intervention increased SDNN, RMSSD, and HF in all the studies, although the difference did not reach statistical significance in some cases. The results regarding LF and LF/HF were not consistent. Conclusion: In general, exercise intervention can improve HRV in cancer patients. It is suggested that SDNN, RMSSD, and HF parameters be used in the evaluation of exercise effects on HRV because these parameters a) have prognostic value and b) more suitably reflect the effects of exercise training in these patients.
