“…The present study extends these findings by being appropriately powered and with a longer follow-up period. Furthermore, our results are in line with a 12-month unsupervised HIIT intervention, where participants were able to choose from several HIIT protocols, which also failed to demonstrate beneficial effects onVO 2max (Roy et al, 2018). Effectiveness of an exercise program to induce changes inVO 2peak is dependent upon the intensity, duration, and frequency of exercise (Wenger and Bell, 1986).…”

“…Compared to moderate-intensity exercise, exercise with higher intensity requires less time to achieve the same or even superior health benefits (Helgerud et al, 2007;Nes et al, 2012). However, compliance is necessary and successful long-term interventions outside controlled environments are lacking, likely due to low adherence (Williams et al, 2007;Gray et al, 2016;Roy et al, 2018). Thus, alternatives to traditional exercise that promote independent exercise behavior are warranted.…”

Rationale: Exergaming may be a viable alternative to more traditional exercise. As highintensity exercise can provide substantial health benefits, the purpose of this study was to investigate the long-term effectiveness of providing inactive adults with access to a high-intensity exergaming platform. Methods: In this study, 52 inactive adults (<150 min of exercise per week), aged 18 years or older, were randomized (1:1) into an exergaming (N = 27) or a control group (N = 25). Exergaming participants were given access to the Playpulse exergaming platform for 6 months, where they decided how frequently they wanted to use the platform. The primary outcome measure, analyzed with a mixed model, was peak oxygen uptake (VO 2peak). Secondary outcomes included body composition, blood pressure, and blood markers of cardiometabolic health. Results: MeanVO 2peak at 6 months was 42.3 (SD 7.0) mL•kg −1 •min −1 and 41.9 (SD 7.4) mL•kg −1 •min −1 for the exergaming and control group, respectively with no significant between-group differences (-0.7, 95% CI-2.7 to 1.3, P = 0.49). Apart from increased moderate-intensity physical activity in the exergaming group at 3 months (21.9 min•day −1 , 95% CI: 2.2 to 41.5, P = 0.03) compared to the control group, there were no significant between-group differences for any outcome at either 3 or 6 months. On average, participants in the exergaming group performed 12 (SD 13) exergaming sessions with an average heart rate of 74.5 (SD 7.5)% of maximum heart rate, throughout the intervention. Conclusion: Due to low exergaming frequency over the 6-month intervention, exergaming participants showed no significant health benefits compared to control. Our study indicates that although the Playpulse exergaming platform is found enjoyable, this is not enough to motivate inactive adults to regularly engage in exercise and thereby improve health.

“…High-intensity interval training (HIIT), defined as alternating short bursts of high-intensity exercise and light exercise or passive recovery periods, has been considered a good alternative, more time-efficient strategy to MICT. Existing systematic reviews and meta-analyses have revealed that HIIT has more significant effects on abdominal and visceral fat reduction and cardiorespiratory fitness improvement in overweight and obese adults than MICT (Maillard et al, 2018;Roy et al, 2018). Moreover, HIIT can reduce metabolic risk factors in type 2 diabetes more effectively than MICT (Costigan et al, 2015;Hannan et al, 2018).…”

The main objective of this meta-analysis was to compare the effectiveness of high-intensity interval training (HIIT) and of moderate-intensity continuous training (MICT) on cardiometabolic health in childhood obesity and determine whether HIIT is a superior form of training in managing obese children's metabolic health. Methods: Relevant studies published in PubMed, Web of Science, Embase, the Cochrane Library, EBSCO, and CNKI were searched, restricted to those published from inception to 1 October 2019. Only randomized controlled trials (RCTs) depicting the effect of HIIT on childhood obesity were included. Results: Nine RCTs involving 309 participants were included in the meta-analysis. Among the 309 participants, 158 subjects were randomized for HIIT, while the others were randomized for MICT. Significant differences were observed in the body weight (mean difference [MD] = −5.45 kg, p = 0.001), body mass index (BMI; MD = −1.661 kg/m 2 , p = 0.0001), systolic blood pressure (SBP; MD = −3.994 mmHg, p = 0.003), and diastolic blood pressure (DBP; MD = −3.087 mmHg, p = 0.0001) in the HIIT group relative to the baseline values. Similar effects were found in the MICT group, as depicted by the significantly decreased values for body weight (MD = −4.604 kg, p = 0.0001), BMI (MD = −2.366 kg/m 2 , p = 0.0001), SBP (MD = −3.089 mmHg, p = 0.019), and DBP (MD = −3.087 mmHg, p = 0.0001). However, no significant differences were observed in the changes in body weight, BMI, SBP, or DBP between the HIIT and MICT groups. Furthermore, our studies showed that both HIIT and MICT could significantly improve VO 2peak (HIIT, MD = 4.17 ml/kg/min, 95% CI: 3.191 to 5.163, p = 0.0001; MICT, MD = 1.704 ml/kg/min, 95% CI: 0.279 to 3.130, p = 0.019). HIIT also showed more positive effects on VO 2peak (SMD = 0.468, 95% CI: 0.040 to 0.897, p = 0.006) than MICT. Conclusion: HIIT positively affects the cardiometabolic risk factors in childhood obesity. Similar positive effects on body composition and blood pressure were established. Moreover, HIIT can improve cardiorespiratory fitness more significantly than MICT. These findings indicate that HIIT may be an alternative and effective training method for managing childhood obesity.

“…After completing the baseline survey and physical fitness test, the computer random list generated by SPSS 16.0 software was used for randomization. Eligible patients were randomly divided into the experimental group and the control group, with a ratio of 1:1 [23]. The group numbers were enclosed in a carbon-free envelope.…”

Background: The purpose of this study is to verify the improvement of remote qigong intervention on the quality of life and physical fitness of breast cancer patients after surgery by means of a randomized controlled trial, and to compare it with the conventional exercise combination of aerobic exercise and resistance training. Methods/design: The research approach applied in this study is a randomized controlled trial. After completing the baseline questionnaire and physical fitness test, participants were randomly assigned to either the qigong group or the combined exercise rehabilitation group. Patients in the qigong group performed Qigong-Baduanjin twice a week for 30 minutes each time under remote guidance and practiced Baduanjin by themselves at other times. Patients in the combined exercise rehabilitation group were given resistance training twice a week for 30 minutes under remote guidance, and walking the rest of the time. At the end of the 12-week intervention, outcomes testing and data collection were carried out. The primary outcomes are quality of life, measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the Functional Assessment of Cancer Therapy-Breast (FATC-B). The secondary outcomes include cardiopulmonary endurance, upper limb strength, lower limb strength and skinfold thickness.Discussion: The importance of postoperative exercise rehabilitation for breast cancer has been gradually accepted by more and more doctors and patients, but further research and development of simple and practical means of exercise rehabilitation are necessary. Remote qigong intervention for breast cancer patients via the Internet will be a great alternative.
