The Different Therapeutic Effects of Traditional Chinese Medicine Shensong Yangxin Capsule and Salubrinal in High-intensity Exercise-induced Heart Failure in Rats with Acute Myocardial Infarction.

Currently, endoplasmic reticulum stress is studied utilizing a dephosphorylation inhibitor (Sal). The traditional Chinese patent medicine and simple formulation Shensong Yangxin Capsule is a commonly used medication for the treatment of arrhythmia. However, the efficacy and underlying mechanism of the capsule in treating post-ischemic heart failure in myocardial tissue have not yet been investigated. The therapeutic effects and the underlying mechanism of the Shensong Yangxin Capsule (SSYX) and the dephosphorylation inhibitor Salubrinal (Sal) on heart failure (HF) induced by high-intensity exercise in rats with acute myocardial infarction (AMI) were investigated. Male infants of 8 weeks Spragge-Dawley (SD) rats were randomly assigned to one of four groups: sham surgery group, AMI+placebo group, AMI+Shensong Yangxin Capsule group (AMI+SSYX), and AMI+Sal administration group. Rats' myocardial infarction was induced by left coronary artery ligation. Rats were subjected to a 3-week high-intensity exercise program to simulate heart failure after 7 days of postoperative rest. After the fourth postoperative week, echocardiography was applied to determine the left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), and left ventricular systolic volume (LVESV) in each group. HE and TUNEL labeling were employed to examine the morphology of cardiac cells and measure the percentage of apoptosis in each group; Western blotting was applied to detect the cardiomyocyte apoptosis-related proteins p-JNK, p-P38, and NOX2, while ELISA was used to detect glutathione(GSH), malondialdehyde (MDA), and superoxide dismutase (SOD) in serum. Following a 4-week drug intervention:(1)LVFS and LVEF in the AMI+placebo group were statistically significantly reduced, while LVESV were significantly higher, compared to those in the sham surgery group (P<0.05); The AMI+SSYX group performed statistically significantly better than the AMI+placebo group(P<0.05). (2) The myocardial cells in the AMI+placebo group exhibited significant swelling and inflammatory cell infiltration; the myocardial cells in the AMI+SSYX group and AMI+Sal group displayed mild swelling and minimal inflammatory cell infiltration; the AMI+SSYX group's myocardial cell morphology was superior to that of the AMI+Sal group; (3) The apoptosis rate of the AMI+placebo group was around 95%, greater than that of the sham surgery group (2.55%). The apoptosis rate of the AMI+SSYX group is approximately 21%, while the apoptosis rate of the AMI+Sal group is about 43%. (4) In the AMI+placebo group, p-JNK, p-P38, and NOX2 protein expression dramatically increased compared to the sham surgery group. The expression of p-P38, NOX2, and p-JNK/t-JNK was considerably reduced in the AMI+Shensong group and AMI+Sal group, compared to the AMI+placebo group. (P<0.01)The AMI+SSYX group's result is superior to that of the AMI+Sal group. (5) Compared to the sham surgery group, the serum levels of SOD and GSH were significantly lower, and MDA was significantly higher in the AMI+placebo group. Compared to the AMI+placebo group, the serum levels of SOD and GSH were significantly higher, and MDA was significantly lower in the AMI+SSYX group and the AMI+Sal group. (P<0.05) Conclusion: In rats with acute myocardial infarction in high-intensity exercise-induced heart failure, Shensong Yangxin Capsule dramatically reduces myocardial cell death and cardiac dysfunction. SSYX has a shorter course of treatment and a better therapeutic effect than Sal.

Effectiveness of Virtual Reality-based Rehabilitation and High-intensity Exercise Program for Total Knee Arthroplasty Patients: A Randomised Controlled Trial

Effectiveness of Virtual Reality-based Rehabilitation and High-intensity Exercise Program for Total Knee Arthroplasty Patients: A Randomised Controlled Trial

Multimodal prehabilitation (Fit4Surgery) in high-impact surgery to enhance surgical outcomes: Study protocol of F4S PREHAB, a single center stepped wedge trial.

High-impact surgery imposes a significant physiological and functional burden and is associated with substantial postoperative morbidity. Multimodal prehabilitation has demonstrated a reduction in postoperative complications and enhanced functional recovery, mainly in abdominal cancer surgery. Common preoperative risk factors shared among patients undergoing high-impact surgery, extending beyond abdominal cancer surgery procedures, suggest the relevance of multimodal prehabilitation to a broader patient population. This stepped wedge trial primarily aims to examine the hospital-wide effect of multimodal prehabilitation, compared to standard preoperative care, on the occurrence and severity of postoperative complications. Secondary and tertiary endpoints include length of hospital stay, physical fitness, nutritional status, mental health, intoxications, and cost-effectiveness of the intervention. The Fit4Surgery (F4S) PREHAB trial is a monocenter stepped wedge trial in an academic hospital. Adult patients, divided into 20 health clusters based on specific diagnoses, will be assessed for eligibility and receive usual preoperative care or multimodal prehabilitation. Patient enrollment commenced in March 2021 and continues up to and including April 2024. The intervention consists of a high-intensity exercise program, a nutritional intervention, psychological support, and smoking and alcohol cessation. The primary outcome will be measured by the Clavien-Dindo classification (grade II or higher) and the Comprehensive Complication Index (CCI). Multimodal prehabilitation potentially reduces postoperative complications and enhances functional recovery. This is the first study to determine the hospital-wide effect and cost-effectiveness of multimodal prehabilitation in patients across various surgical specialties.

Mechanisms of adaptation to high intensity exercise in hypertrophic cardiomyopathy

Abstract Background Many individuals with hypertrophic cardiomyopathy (HCM) demonstrate exercise limitation. For a proportion this may be related to their overall cardiorespiratory fitness influenced by physical activity habits, body mechanics, or habitus. In others there is evidence of central and/or peripheral pathophysiology. However, some individuals with HCM demonstrate favourable adaptation to exercise. In the SAFE-HCM study, participants who underwent 12 weeks of high intensity exercise showed significant improvement in exercise indices including peak VO2, VO2/kg at anaerobic threshold (AT), time to AT, and overall exercise time compared to a usual care group. Purpose There have been no studies investigating the mechanistic adaptation(s) to exercise in HCM. This sub-study aimed to identify whether the observed improvements in exercise indices were attributable to central or peripheral adaptation. Methods Eighty patients with HCM (45.7±8.6 years) underwent baseline clinical, quality of life and psychological assessment. Individuals were randomised to a 12-week high intensity exercise programme (n=40) or usual care (n=40). Baseline evaluation was repeated at 12 weeks. The Fick equation (oxygen uptake (VO2) = cardiac output (CO) X (arterial-venous oxygen content (a-vO2 difference)) was used to assess whether central and/or peripheral adaptation was responsible for observed improvements. 2D speckle tracking imaging was utilised to calculate left ventricular longitudinal strain from the apical 2-, 3- and 4 chamber views (EchoPAC, V202, GE Healthcare). Results 12-weeks of high intensity exercise training produced a statistically significant increase in CO (1.1±0.4 L/min, CI (0.2,2.0), p=0.016) compared with the usual care group. There was no difference in the change in a-vO2 difference between groups (p=0.682) suggesting central adaptation to high intensity exercise. This was driven by an increase in stroke volume (SV) (6.1±3.0ml, CI (0.1,12.2), p=0.047) rather than an increase in heart rate (0.6±3.6 bpm, CI (-6.6,7.7), p=0.874). However, there was no change in resting myocardial deformation to account for the observed improvement in CO. Analysis of strain data demonstrated no difference in resting regional 4Ch (-0.7±0.6, CI (-1.9, 0.5), p=0.270) 3Ch (-1.1±0.9, CI (-2.8, 0.6), p=0.201), 2Ch (-1.3±0.9, CI (-3.1, 0.5), p=0.162) or average global longitudinal strain (0.9±0.6, CI (-2.2,0.3), p=0.144) between groups at 12 weeks. Conclusion Favourable central adaptations, predominantly driven by an increase in SV, enable improvements in exercise capacity following a high intensity exercise programme. Further studies are required to understand the physiological processes underlying this adaptation including assessment of myocardial deformation at peak exercise

School-based high-intensity interval exercise program in children with overweight induce a greater improvements in body composition and physical fitness than moderate-intensity continuous exercise

BackgroundHigh-intensity interval running exercise (HIIE) is emerging as a time-efficient exercise modality for improving body composition and fitness in comparison with moderate-intensity continuous aerobic exercise (MICE); however, existing evidence is still unclear in children with overweight and thus we compared the effects of HIIE and MICE on body composition, muscular, and cardiorespiratory fitness in children with overweight.MethodsIn this randomized study, 40 male children with overweight aged 7–10 years were divided into an 8-week exercise regime: (1) HIIE group [n = 20; 2 sets of 15 × 20s at 85–95% maximal aerobic speed (MAS) separated by 15 × 20s recovery at 50% MAS, 3 days per week] and (2) MICE group [n = 20; 30 min at 60–70% MAS, 3 days per week]. Body composition, muscular and cardiorespiratory fitness were assessed before and after the 8-week intervention at similar times and conditions of the day.ResultsFollowing the 8-week HIIE protocol, weight, BMI, and fat mass decreased significantly (weight: − 1.4% vs. 0.2%, p < 0.05; BMI: − 3.1% vs. − 0.7%, p < 0.05; fat mass: − 7.7% vs. − 1.6%, p < 0.01) as compared with MICE; while the VO2peak and MAS increased significantly in both groups, the increase in HIIE group was significantly greater than that of MICE group (VO2peak: 10.3% vs. 3.5%, p < 0.01; MAS:7.7% vs. 4.5%, p < 0.05). Although significant improvements in muscular fitness were observed in HIIE and MICE groups [counter movement jump (CMJ): 7.8% vs. 5.4%; sprinting ability: − 3.7% vs. − 1.7%], no significant differences were seen between them (p > 0.05).ConclusionOur findings suggested that school-based HIIE intervention was highly in improving body composition and cardiorespiratory fitness of children with overweight than the MICE regime; however, MICE still provided improvements over time that were just not to the same magnitude of HIIE.

Evaluating a Telemedicine Video Game-Linked High-Intensity Interval Training Exercise Programme in Paediatric Heart Transplant Recipients.

Paediatric heart transplant recipients (HTRs) have reduced exercise capacity, physical activity (PA), health-related quality of life (HRQoL), and self-efficacy towards PA. Exercise interventions have demonstrated improvements in exercise capacity and functional status in adult HTRs, with a specific emerging interest in the role of high-intensity interval training (HIIT). Studies of exercise interventions in paediatric HTRs have been limited and nonrandomized to date. HIIT has not yet been evaluated in paediatric HTRs. We thus seek to evaluate the safety and feasibility of a randomized crossover trial of a 12-week, home-based, video game-linked HIIT intervention using a cycle ergometer with telemedicine and remote physiological monitoring capabilities (MedBIKE) in paediatric HTRs. The secondary objective is to evaluate the impact of the intervention on (1) exercise capacity, (2) PA, (3) HRQoL and self-efficacy towards PA, and (4) sustained changes in secondary outcomes at 6 and 12 months after intervention. After a baseline assessment of the secondary outcomes, participants will be randomized to receive the MedBIKE intervention (12 weeks, 36 sessions) or usual care. After the intervention and a repeated assessment, all participants will cross over. Follow-up assessments will be administered at 6 and 12 months after the MedBIKE intervention. We anticipate that the MedBIKE intervention will be feasible and safely yield sustained improvements in exercise capacity, PA, HRQoL, and self-efficacy towards PA in paediatric HTRs. This study will serve as the foundation for a larger, multicentre randomized crossover trial and will help inform exercise rehabilitation programmes for paediatric HTRs.

The effect of intense exercise on muscle power and functional abilities of obese people

BACKGROUND: Obesity, expressed as a high body mass index (BMI), is associated with a risk of decrease in functional capacity and muscle strength, in particular in weight-bearing joints, but so far, no study has been able to show a sufficiently strong relationship between these factors. two options in conclusion.AIM: This study was conducted to quantify the effect of intense exercise on the functional capacity and muscle power of obese individuals and the risk of knee osteoarthritis.MATERIALS AND METHODS: The present research project is characterized as a clinical trial, cross-sectional, and uncontrolled research. All participants had a body mass index from 30.6 kg/m² to 34.9 kg/m² and reported not working out in the last 3 months prior to this experiment. Before their involvement, all participants were informed during an initial interview about the experimental procedure, the nature of the research, and the test protocols. They gave their written and signed informed consent to voluntarily participate in this research and completed two questionnaires. Participants in our study were recruited from sports centers, social clubs, and word of mouth. A total of 78 participants responded to the call articipated in our training protocol which was composed of two main parts. The first one is the «Anthropometric measurements tests» and the second one is the «Functional capacity tests» that were done in a gym. The participants were divided randomly into two experimental. After the end of every phase of the experiment, some members of each group were moved randomly to the other group.RESULTS: The final results of the intra-class correlation coefficient measurements for a set of tests showed strong reliability among members of each examined group. For the handgrip strength tests of the right and left hands, the results were 0.850 and 0.892, respectively. For the squat jump and countermovement jump tests, the results were 0.966 and 0.932, respectively. The results were 0.896 and 0.945 for walking 6 meters with or without double tasks. Finally, for the TUG and TUP-DT tests, the results were 0.520 and 0.663, respectively. After analyzing and interpreting the data for the functional capacity tests, the following results were obtained: For the 5 sit-stand test, the result was (F (3.87)=4.22; p=0.008, ηp2=0.127). For the Time up and go test, the result was (F (3.87)=4.56; p=0.019, ηp2=0.136), and for the 6 m walk, the result was (F (3.87)=3.81; p=0.013, ηp2=0.116). Finally, the 5X sit-to-stand test at 48 hours was lower than the base value (p=0.024), while the TUG immediately after the post was lower than the base value.CONCLUSION: In conclusion, the results of this study demonstrate the positive impact of intense exercise on muscle power and functional capacity in obese individuals. These findings suggest that high-intensity physical activity may be an effective means of improving the health and quality of life of obese individuals. Therefore, it is recommended that obese individuals include high-intensity exercise in their regular exercise program to reap these health benefits. However, it is important to emphasize the importance of consulting a healthcare professional before starting a high-intensity exercise program to avoid the risk of injury or health complications.

The Effect of High Intensity Interval Training in Reducing the Risk of Cardiovascular Diseases in Obese Type-I Individuals

Background This study aimed to investigate the potential of High-Intensity Interval Training (HIIT) as a non-pharmacological intervention to reduce the risk of cardiovascular disease in a specific population. Methods A quasi-experimental design was employed; involving 20 young adults aged 25-30 recruited from a fitness centre. The participants underwent an 8 weeks high-intensity exercise program consisting of 3 weekly sessions. Baseline measurements of body mass, height, BMI, cholesterol, triglycerides, LDL, and HDL levels were taken before the intervention. Post-intervention measurements were obtained at the end of the 8 weeks. Results The results demonstrated significant improvements in various parameters following the 8 weeks workout program. BMI decreased from 32.2±1.42 to 31.67±1.45, while cholesterol levels decreased from 221.37±9.3 to 201±9.64, indicating a reduction in total cholesterol. Triglyceride levels decreased from 181.5±10.98 to 170.1±11.93. LDL values decreased from 144.5±8.9 to 134.2±8.13, indicating a decrease in low-density lipoprotein. Additionally, HDL levels increased from 36.53±4.53 to 46±5.44, reflecting an increase in high-density lipoprotein levels. All these changes were statistically significant (p≤0.005). Conclusion The findings suggest that HIIT is an efficient and effective exercise for sedentary and inactive young males. The study supports using HIIT as a non-pharmacological approach to improve physical well-being, enhance fitness, and reduce the risk of cardiovascular diseases. HIIT provides a time- and cost-efficient alternative for individuals with limited exercise time who still desire optimal health and fitness outcomes.

Effect of Multimodal Prehabilitation on Reducing Postoperative Complications and Enhancing Functional Capacity Following Colorectal Cancer Surgery

Colorectal surgery is associated with substantial morbidity rates and a lowered functional capacity. Optimization of the patient's condition in the weeks prior to surgery may attenuate these unfavorable sequelae. To determine whether multimodal prehabilitation before colorectal cancer surgery can reduce postoperative complications and enhance functional recovery. The PREHAB randomized clinical trial was an international, multicenter trial conducted in teaching hospitals with implemented enhanced recovery after surgery programs. Adult patients with nonmetastasized colorectal cancer were assessed for eligibility and randomized to either prehabilitation or standard care. Both arms received standard perioperative care. Patients were enrolled from June 2017 to December 2020, and follow-up was completed in December 2021. However, this trial was prematurely stopped due to the COVID-19 pandemic. The 4-week in-hospital supervised multimodal prehabilitation program consisted of a high-intensity exercise program 3 times per week, a nutritional intervention, psychological support, and a smoking cessation program when needed. Comprehensive Complication Index (CCI) score, number of patients with CCI score more than 20, and improved walking capacity expressed as the 6-minute walking distance 4 weeks postoperatively. In the intention-to-treat population of 251 participants (median [IQR] age, 69 [60-76] years; 138 [55%] male), 206 (82%) had tumors located in the colon and 234 (93%) underwent laparoscopic- or robotic-assisted surgery. The number of severe complications (CCI score >20) was significantly lower favoring prehabilitation compared with standard care (21 of 123 [17.1%] vs 38 of 128 [29.7%]; odds ratio, 0.47 [95% CI, 0.26-0.87]; P = .02). Participants in prehabilitation encountered fewer medical complications (eg, respiratory) compared with participants receiving standard care (19 of 123 [15.4%] vs 35 of 128 [27.3%]; odds ratio, 0.48 [95% CI, 0.26-0.89]; P = .02). Four weeks after surgery, 6-minute walking distance did not differ significantly between groups when compared with baseline (mean difference prehabilitation vs standard care 15.6 m [95% CI, -1.4 to 32.6]; P = .07). Secondary parameters of functional capacity in the postoperative period generally favored prehabilitation compared with standard care. This PREHAB trial demonstrates the benefit of a multimodal prehabilitation program before colorectal cancer surgery as reflected by fewer severe and medical complications postoperatively and an optimized postoperative recovery compared with standard care. trialregister.nl Identifier: NTR5947.

High-intensity exercise prescription guided by heart rate variability in breast cancer patients: a study protocol for a randomized controlled trial

BackgroundBreast cancer is a chronic disease with a large growth in its treatments, prognosis, improvements, side effects and rehabilitation therapies research. These advances have also highlighted the need to use physical exercise as a countermeasure to reduce the cardiotoxicity of pharmacological treatments, increase patients' strength and quality of life and improve body composition, physical condition and mental health. However, new investigations show the need for a closed exercise individualisation to produce higher physiological, physical and psychological benefits in remote exercise programs. To this end, the present study will use, in a novel way in this population, heart rate variability (HRV) as a measure for prescribing high-intensity training. Thus, the primary objective of this randomised clinical trial is to analyse the effects of a high-intensity exercise program daily guided by HRV, a preplanned moderate to high-intensity exercise intervention and a usual care group, in breast cancer patients after chemotherapy and radiotherapy treatments.MethodsFor this purpose, a 16-week intervention will be carried out with 90 breast cancer patients distributed in 3 groups (a control group, a moderate to high-intensity preplanned exercise group and a high-intensity exercise group guided by HRV). Both physical exercise interventions will be developed remotely and supervised including strength and cardiovascular exercises. Physiological variables, such as cardiotoxicity, biomarkers, lipid profile, glucose, heart rate and blood pressure; physical measures like cardiorespiratory capacity, strength, flexibility, agility, balance and body composition; and psychosocial variables, as health-related quality of life, fatigue, functionality, self-esteem, movement fear, physical exercise level, anxiety and depression will be measure before, after the intervention and 3 and 6 months follow up.DiscussionPersonalized high-intensity exercise could be a promising exercise intervention in contrast to moderate-intensity or usual care in breast cancer patients to reach higher clinical, physical and mental effects. In addition, the novelty of controlling HRV measures daily may reflect exercise effects and patients' adaptation in the preplanned exercise group and a new opportunity to adjust intensity. Moreover, findings may support the effectiveness and security of physical exercise remotely supervised, although with high-intensity exercise, to reach cardiotoxicity improvements and increase physical and psychosocial variables after breast cancer treatments.Trial registration ClinicalTrials.gov nº NCT05040867 (https://clinicaltrials.gov/ct2/show/record/NCT05040867).

Potential involvement of circulating extracellular vesicles and particles on exercise effects in malignancies.

Physical activity and exercise have been widely related to prevention, treatment, and control for several non-communicable diseases. In this context, there are innumerous pre-clinical and clinical evidence indicating the potential role of exercise, beyond cancer prevention and survival, improved quality of life, including on psychological components, bone health and cachexia, from cancer survivors is described as well. This mini-review raises the potential role of circulating extracellular and particles vesicles (EVPs) cargo, as exerkines, conducting several positive effects on adjacent and/or distant tissues such as tumor, immune, bone and muscle cells. We highlighted new perspectives about microRNAs into EVPs changes induced by exercise and its benefits on malignancies, since microRNAs can be implicated with intricated physiopathological processes. Potential microRNAs into EVPs were pointed out here as players spreading beneficial effects of exercise, such as miR-150-5p, miR-124, miR-486, and miRNA-320a, which have previous findings on involvement with clinical outcomes and as well as tumor microenvironment, regulating intercellular communication and tumor growth. For example, high-intensity interval aerobic exercise program seems to increase miR-150 contents in circulating EVPs obtained from women with normal weight or overweight. In accordance circulating EVPs miR-150-5p content is correlated with prognosis colorectal cancer, and ectopic expression of miR-150 may reduce cell proliferation, invasion and metastasis. Beyond the involvement of bioactive miRNAs into circulating EVPs and their pathways related to clinical and preclinical findings, this mini review intends to support further studies on EVPs cargo and exercise effects in oncology.

Más allá de los límites: el ejercicio terapéutico como herramienta clave en la lesión medular. Protocolo de trabajo

Introduction: People with spinal cord injury (SCI) suffer from many comorbidities due to a sedentary lifestyle. Current scientific evidence suggests that increasing physical activity levels in these people would reduce morbidity and improve their quality of life and independence. However, current guidelines suggest exercise intensities that are considered inadequate compared to a population without pathology. Objectives: To develop a high-intensity exercise programme to improve functionality and reduce specific risk factors in people with spinal cord injury. Methods: An exercise programme for chronic SCI is presented that requires 2 groups (experimental and control). The experimental group will perform a programme of Strength, Aerobic and Trunk Stabilising Muscle Control, 3 times a week for 6 months, while the control group will receive educational talks on the importance of physical activity and healthy lifestyle habits.

Reassured on a background of vulnerability - people with microvascular angina 12 months after high-intensity physical exercise program

ABSTRACT Purpose Physical activity is recommended for patients with coronary microvascular dysfunction, however, avoided due to fear about the heart. The aim is to achieve an understanding of the meaning of physical activity one year after participating in a high-intensity exercise training program. Method Twelve people were interviewed using a phenomenological hermeneutic approach. Results Four themes were formulated and revealed that one year after participating in high-intensity exercise training participants had an awareness of the meaning of the project, their chest pain and daily life: Being reassured, Daily life’s impact on chest pain and continuing doing high-intensity exercise training, A strengthened body and mind, Being part of a group of people with similar problems. Comprehensive understanding was formulated as “Being reassured according being physically active in a background of vulnerability”. Conclusion This study indicates that by going through the high-intensity exercise training program the person regains more unity with the lived body and an unfolding life. A person-centred approach is suggested including an underlying dimension of vulnerability. A lifeworld led care means meeting the patient in their way of relating to the world bodily and existentially. Taking this understanding into consideration will advance the requirements for establishing person-centred care.

Intracellular Oxidative Stress Induced by Physical Exercise in Adults: Systematic Review and Meta-Analysis.

A physical exercise program is one of the commonly used methods for improving an individual’s antioxidative capacity. However, an inappropriate physical exercise program would induce extra oxidative stress (OS), and the relationship between the details of a physical exercise protocol and the severity of intracellular OS is still unclear. A systematic review and meta-analysis of randomized controlled trials were conducted by searching PubMed, Medline, and Web of Science with the eligibility criteria: (1) participants over 18 years old; (2) physical exercise interventions; (3) 8-hydroxydeoxyguanosine, F2-isoprostanes, and protein carbonyls (PCs) as outcome measures; (4) published in English and peer-reviewed. 12 studies were included, and the data of 8 in them were pooled together. The agreement between authors reached a kappa value of 0.73. The results of the meta-analysis showed that: (1) the level of OS did not depend on the absolute intensity of physical exercise but on both the intensity and the volume of exercise; (2) high-intensity aerobic exercise (HIAE) and a combined protocol of HIAE and resistance training had the highest potential to induce large OS in unhealthy people; (3) the OS induced by moderate-to-high intensity aerobic exercise was significantly larger than that induced by ordinary life activities in healthy adults; (4) high-intensity interval training and moderate-intensity aerobic exercise had the lowest and sub-lowest probabilities to induce high intracellular OS for unhealthy adults. activities induce OS in various tissues in the human body, and the severity of OS depends on many factors of physical exercises as well as the health condition of an individual. A high-intensity and high-volume physical exercise program has the largest possibility of inducing severe OS, while a moderate-intensity aerobic exercise program and a high-intensity interval training program with a relatively low volume might be beneficial to the redox balance for unhealthy individuals. In conclusion, continuous aerobic exercise under moderate-intensity or high-intensity interval training could be recommended to enhance the body’s capacity for maintaining redox balance, especially for unhealthy individuals.

High-Intensity Functional Training For Children With Autism Improves Social Skills, ASD Symptoms And Physical Performance

PURPOSE: This study assessed the feasibility and effectiveness of a 10-wk high intensity exercise program offered after-school for children with autism spectrum disorder (ASD) without intellectual disability. METHODS: Children with ASD (n = 11, M age: 9.53 ± 2.1 yr) engaged in a 1 hr after-school high intensity functional training exercise session, 2 d/wk for 10 wks that targeted social skills, ASD symptoms, and physical performance. Each group exercise session included an instruction period, warm-up, high intensity workout, related game, and cool-down. Social skill and symptom outcome measures included the Adapted Skillstreaming Checklist (ASC) and Social Responsiveness Scale 2nd Edition, School Age Form (SRS-2). Physical performance data (i.e., strength, flexibility, PACER aerobic fitness, power) were also collected. Paired t-tests were used to assess pre to post program performance differences. Participant and parent/guardian satisfaction surveys (7-point Likert scale) were administered following completion of the program. RESULTS: Feasibility and safety were supported in high levels of fidelity (96%), participant and parental satisfaction (4.66, 6.53 out of 7, respectively), and attendance (90% of all sessions), and there were no adverse events or injuries. Pre-post comparisons indicated significant improvements and large effects in social skills (ASC = 87.5 to 118.73; d = 1.95) and ASD symptoms (SRS-2 = 83.6 to 71.36; d = .98) and medium-to-large effects on tests of physical performance (PACER [6.9 to 9.9 laps; d = .86], 60 sec max sit-ups [13.3 to 23.5 reps, d = .58], 60 sec max body weight squats [19.5 to 29.6; d = .61]). CONCLUSION: This after-school high intensity exercise program for children with ASD without intellectual disability was feasible (high fidelity, satisfaction) and improved social functioning, ASD symptoms and physical performance.

Soldiers' Heart: A Prospective Study of Cardiac Remodeling in Soldiers Undergoing Progressive Intensity Exercise Training.

Most studies reporting cardiac changes with exercise have been cross sectional. The few available longitudinal studies have lacked standardization for environmental confounders. We prospectively assessed the relationship between increasing exercise intensity and cardiac remodeling in a highly standardized cohort of healthy young army soldiers. Sixty-three male army recruits (22 ± 3 yr) underwent a 12-wk moderate-intensity mixed strength and endurance exercise program, followed by a further 15-wk high-intensity exercise program, with highly controlled exercise, diet, and sleep patterns. Fitness (multistage fitness test), anthropometry, and 2D echocardiography were assessed. Moderate-intensity exercise was associated with increased fitness and decreased body fat % (both P < 0.01). There was no significant incremental change in these parameters after high-intensity exercise. By contrast, both moderate- and high-intensity exercises were associated with dose-dependent increases in left atrial and left ventricular (LV) volumes, LV mass, and right ventricular (RV) size (all P < 0.01). At the end of high-intensity training, 51% had a dilated LV and 59% had a dilated RV compared with published normal ranges. Almost all had normal LV systolic function and strain before and after exercise training. A small number of soldiers had mildly decreased RV systolic function at baseline and after moderate-intensity exercise (3% and 6%, respectively). We describe "soldiers' heart," which is characterized by balanced chamber dilatation, normal LV mass, and largely normal systolic function and myocardial strain. This prospective and highly controlled longitudinal study also found that increasing intensity exercise was associated with increasing chamber dimensions, which paralleled an increase in fitness after moderate-intensity exercise. After high-intensity exercise, however, cardiac chamber size continued to increase, but fitness did not increase further.

Remotely Supervised Exercise Programmes to Improve Balance, Mobility, and Activity Among People with Moderate to Severe Traumatic Brain Injury: Description and Feasibility.

Further investigation into the feasibility of using videoconferencing and activity tracking devices to provide high-intensity home-based exercise programmes for people with a moderate or severe traumatic brain injury (TBI) is needed to inform clinical implementation and patient adoption. This study aimed to (1) determine if home-based telerehabilitation exercise programmes were feasible for people with a moderate or severe TBI and (2) better understand the lived experience of people with a TBI and their family partners with this programme. A mixed-methods approach consisting of measures of feasibility and semi-structured interviews was used. Five participants with moderate to severe TBI and their family partners completed two high-intensity home-based exercise programmes delivered remotely by a physiotherapist (i.e., daily and weekly). Telerehabilitation services in home-based settings were feasible for this population. Adherence and engagement were high. Dyads were satisfied with the use of technology to deliver physiotherapy sessions. Telerehabilitation provides a delivery option that allows people with TBI to spend energy on therapy rather than on travelling. A pre-programme training on key components, such as the use of technology, safety precautions, and communication methods, likely improved the overall feasibility. Further research is needed to better understand the effectiveness of such a programme on balance, mobility, and physical activity levels.

Supervised Intensive Exercise for Strengthening Exercise Health Beliefs in Patients With Axial Spondyloarthritis: A Multicenter Randomized Controlled Trial.

To evaluate the effect of a 3-month supervised high-intensity exercise program on exercise health beliefs in patients with axial spondyloarthritis. This was secondary analysis of a randomized controlled trial. Participants (ages 23-69 years) were randomized to an exercise group (n = 50) or a control group (n = 50). The intervention was an individually guided cardiorespiratory and strength exercise program performed 2 times per week, plus an additional individual exercise session of personal choice. The control group received standard care and instructions to maintain their physical activity level. Exercise health beliefs using the Exercise Health Beliefs questionnaire (range 20-100, 100 = best), i.e., barriers, benefits, self-efficacy and exercise impact on arthritis, and physical activity, were assessed with self-reported questionnaires at baseline, 3 months, and 12 months after inclusion. The majority of the participants in the exercise group (76%) followed ≥80% of the prescribed exercise protocol. There was a significant effect of the intervention on exercise health beliefs at 3 months (estimated mean group differences 4.0 [95% confidence interval (95% CI) 1.4, 6.6]; P = 0.003) and the effect persisted at 12 months follow-up (estimated mean group differences 3.8 [95% CI 1.0, 6.6]; P = 0.008). Participants with higher exercise health beliefs had a higher odds ratio (1.1 [95% CI 1.0, 1.20]; P = 0.003) for being physically active at 12 months follow-up. A supervised high-intensity exercise program had beneficial short- and long-term effects on participants' exercise health beliefs. Stronger exercise health beliefs were positively associated with a higher chance to be physically active on a health-enhancing level at 12 months follow-up.
