Athletes of power sports, often appear to us as a model of a beautiful and healthy body, but the health of the cardiovascular system ofthese athletes has long falls under the gaze of cardiologists and sport physicians. Purpose of the study. A comparative analysis of the influence of a uniform and high-intensity aerobic exercise on blood pressure lowering power sports athletes with hypertension. Research Methods. The study involved 83 representatives of power sports (bodybuilding) with arterial hypertension. The average age of male athletes was 31.2 ± 4.5 years, and the body mass index was 32.4 ± 2.8 kg/m 2. To achieve this goal, the following methods were used: examination, interrogation, triple measurement of blood pressure, ergospirometry and methods of mathematical statistics. Athletes were randomized into three groups: interval training group (n = 33), uniform training (n = 30) and control group (n = 20). For 120 days (3 times a week), the athletes of the main groups performed various aerobic work programs, and the control group athletes trained according to their traditional strength protocol. Results. After 120 days of physical rehabilitation, a similar, significant decrease in systolic and diastolic blood pressure occurred in themain intervention groups. A decrease in blood pressure in the control group was not statistically significant. Conclusions. Despite the similar benefits in cardio-rehabilitation interval work required 38% less time, which can significantly affect adherence to a non-specific for this sport activity and screening of participant’s lengthy rehabilitation.

Objective: The aim of this study was to assess the benefit of using high-intensity interval training for cardiovascular patients undergoing outpatient rehabilitation in a standard short-term (three-week) program in Germany. Design: This is a randomized controlled trial (RCT). Setting: This study was conducted at Cardiowell (Wuppertal, Germany), an outpatient rehabilitation center. Intervention: Patients underwent the typical three-week German outpatient rehabilitation program using either moderate continuous training (i.e. the standard training program) or high-intensity interval training. Main measures: A total of 50 patients of an outpatient rehabilitation center were randomized into two groups. The control group underwent the standard rehabilitation protocol that applied moderate continuous training, and the intervention group trained according to a high-intensity interval protocol. Patients trained on a bicycle ergometer. Peak power output, oxygen uptake parameters, heart frequencies, and blood pressure were compared at the beginning and at the end of the rehabilitation program. Results: After three weeks, the intervention group had improved to a significantly greater extent in maximal performance parameters than the control group: the peak power output (20.9 (±14.1) W; control 8.8 (±10.4) W), maximum oxygen uptake (0.33 (±0.33) L/min; control 0.05 (±0.29) L/min)), relative maximum oxygen uptake (3.4 (±4.2) mL/kg/min; control 0.9 (±3.1) mL/kg/min), and O2 pulse (1.8 (±2.2) mL/heart beat; control 0.35 (±1.7) mL/heart beat). Conclusion: The implementation of high-intensity interval training during a typical three-week German cardiac rehabilitation has the power to increase the outcome for the patients.

IntroductionCOVID-19 is associated with a marked systemic inflammatory response with concomitant cardiac injury and remodelling, but it is currently unknown whether the latter is reversible. Given that high-intensity interval training (HIIT) is a powerful stimulus to improve cardiorespiratory fitness while also eliciting marked anti-inflammatory effects, it may be an important countermeasure of reducing cardiopulmonary morbidity following COVID-19.Methods and analysis40 COVID-19 survivors who have been discharged from hospital will be included in this investigator-blinded randomised study with a 12-week HIIT intervention. Patients will be 1:1 block-randomised by sex to either a supervised HIIT exercise group or standard care (control group). The main hypothesis is that a 12-week HIIT scheme is a safe way to improve loss of cardiac mass and associated cardiorespiratory fitness, despite hypothesised limited HIIT-induced changes in conventional lung function indices per se. Ultimately, we hypothesise that the HIIT scheme will reduce post-COVID-19 symptoms and improve quality of life.Ethics and disseminationThis study is approved by the Scientific Ethical Committee at the Capital Region of Denmark (H-20033733, including amendments 75068 and 75799) and registered at ClinicalTrials.gov (NCT04647734, pre-results). The findings will be published in a peer-reviewed journal, including cases of positive, negative and inconclusive results.Trial registration numberNCT04549337.

Background: Apoptosis is the physiological cell death that in natural conditions leads to the elimination of old, damaged, waste, and harmful cells. The aim of this study was the effect of eight weeks of high-intensity interval training (HIIT) with and without caloric restriction on gene expression of myocardial Bax and Bcl2 in mice. Methods: Present study was an experimental multi-group design with a control group conducted on 30 two-month old male mice. Subjects were divided into five homogenous groups including base control, control, caloric restriction, interval exercise training, and caloric restriction + interval exercise training. Training groups participated in interval exercise training five sessions per week for 8 weeks. The level of gene expression of myocardial Bax and Bcl2 was evaluated by real-time PCR. Data were analyzed using the one-way ANOVA at the level of (P<0.05). Results: The results showed that the training group had a significant increase in gene expression of myocardial Bcl2 in comparison with caloric restriction + exercise training (P<0.05) and a significant decrease in gene expression of myocardial Bax compared to the caloric restriction group (P<0.05). Also, exercise training and exercise training + caloric restriction significantly increased the gene expression of myocardial Bcl2 and significantly decreased Bax/Bcl2 ratio compared to caloric restriction, base control, and control (P< 0.05). Conclusion: It seems that high-intensity interval training without caloric restriction would provide a suitable environment for increasing the integrity of the mitochondrial membrane of myocardial cells and possibly apoptosis.

The paper discusses the effects of high intensity interval aerobic training on blood pressure, body composition, oxidative ability and muscle strength in strength-power athletes of different weight classes. Subjects of examination and physical rehabilitation were 55 hypertensive heavy-weight athletes of comparable age and clinical findings who were randomized into the main (n = 35) and control (n = 20) groups. The main group trained 120 days (3 sessions per a week) on a bicycle ergometer following a high intensity interval; the control group trained in parallel but following the traditional strength developing protocol. Before and on completion of the physical rehabilitation, the sportsmen were interviewed and underwent medical examination including a triple blood pressure measurement, bioimpedometry, ergospirometry, body index calculation, and the test for maximal voluntary strength of m. quadriceps femoris. The rehabilitation improved bioimpedometry parameters, reduced blood pressure noticeably (systolic BP by 4.7 % and diastolic BP by 5.6 %), increased oxygen consumption and quadriceps femoris strength. Investigations showed that the high intensity interval training has a medioprophylactic effect on the cardiovascular system. The authors developed an aerobic training protocol for safe and successful hypertension prophylaxis and therapy in athletes.

Evidence suggests that moderate physical activity (PA) positively relates to creativity and emotional intelligence (EI) in adolescents. However, it is unknown whether cooperative PA (physical exercises in pairs or small groups to enhance motivation, self-efficacy, and pro-social behaviours), performed over less time but at higher intensity, could have similar effects within a school setting. The aim was to analyse the effect of cooperative high-intensity interval training (C-HIIT) on creativity and EI in adolescents aged 12–16 years, and whether improvement effects are different according to weekly PA level. A randomised controlled trial was conducted with a control group (CG, n = 94), which did static stretching, and an experimental group (EG, n = 90), which performed C-HIIT. Both groups performed the activity during 16 minutes at the beginning of physical education (PE) classes. Creativity was assessed with one factor, and EI through four factors (well-being, self-control, emotionality, and sociability). Age and body mass index (BMI) were used as confounders. Both were measured twice (baseline and after 12 weeks). The EG increased well-being and sociability factors after the C-HIIT programme (both p < 0.001). More specifically, inactive adolescents in the EG showed significant improvements in comparison to the CG in creativity, well-being, and sociability ( p = 0.028, p < 0.001, and p < 0.003, respectively). However, we did not find changes among active adolescents. A programme of C-HIIT in PE is a novel strategy to improve creativity and EI, especially in physically inactive adolescents. Starting PE classes with 16 minutes of C-HIIT could be recommended, independently of other activities planned for the session.

Abstract IntroductionCognitive deficit is a common syndrome of methamphetamine (MA) dependence, it relates to decision-making, control ability, and social functioning. High-Intensity Interval Training (HIIT) is a training technique that requests people to work out at full intensity during a short period. A number of studies have already shown the potential effects of HIIT on cognitive roles. A number of studies have already shown the potential effects of HIIT on cognitive function. The purpose of this trial is to evaluate the cognitive effects of HIIT on the individuals of MA dependent. Methods and analysis240 individuals of MA dependent are randomly assigned to High-intensity Interval Training group (HIIT), Moderate-intensity Continuous Training group (MICT) and Control group (CON) respectively. HIIT consists of a 24-minute exercise of high-intensity interval training on a treadmill. MICT consists of a 1-hour body-mind exercise. CON remains their traditional intervention. The experimental period will be 12 months, with 3 interventions weekly for the first 6 months and follow-up for the next 6 months. All subjects will be given both physical and cognitive tests at baseline, after intervention and follow-up. The cognitive performances will be compared by a mixed-model analysis for repeated-measures.DiscussionHIIT training may reduce illicit drug cravings among individuals of MA dependent, it indicates that HIIT has better effect on cognitive functions such as memory and executive function for individuals of MA dependent.Trial RegistrationChiCTR, ChiCTR2000032492, Registered on Aril 30, 2020, Prospective registration, http://www.chictr.org.cn/edit.aspx?pid=52127&htm=4.

Background and Objectives: Appetite is an essential factor in obesity. The present study aimed to evaluate the effect of High-Intensity Interval Training (HIIT) on GLP-1, appetite, and weight of obese mice while maintaining a high caloric diet. Subjects and Methods A total of 24 C57BL/6 mice with a Mean±SD weight of 20.7±1 g were selected. After implementing a high caloric dieting and making them fat (Mean±SD weight: 30.95±3.23 g), they were divided into two groups of training and control. A high caloric diet was maintained for both groups (training and control) until the end of the experiment, while the training group performed HIIT for 8 weeks. Every session of HIIT included 30 minutes of exercise with a progressive intensity of 50% to 60% in low-intensity intervals and 80% to 90% in high-intensity intervals. The independent t test and analysis of variance with repeated measures were used for data analysis. Results Findings of the study indicated that GLP-1 increased significantly in the HIIT training group compared to the control group (P<0.05). In the HIIT group, body weight was significantly higher (P<0.001), and food intake was significantly lower (P<0.001) than those in the control group. Conclusion When consuming high-calorie food, HIIT training can probably cause weight loss through reducing appetite mediated by increasing GLP-1

High-intensity interval training (HIIT) is promoted as a time-efficient strategy to improve body composition but concomitant beer intake, which is common among physically active individuals, may interfere with these effects. The primary aim of this study is to determine the effects of a 10-week (2 days/week) HIIT program on anthropometric and body composition measurements, and to assess whether those effects are influenced by the moderate consumption of beer (at least 5 days/week), or its alcohol equivalent. Young (24 ± 6 years old) healthy adults (n = 72, 35 females) volunteered for a non-training group (Non-Training group) or for HIIT training. Those going for training choose whether they preferred to receive alcohol or not. Those choosing alcohol were randomly allocated for receiving beer (5.4%; T-Beer group) or the equivalent amount of alcohol (vodka; T-Ethanol group) in sparkling water. Those choosing no-alcohol were randomly allocated for receiving alcohol-free beer (0.0%; T-0.0Beer group) or sparkling water (T-Water group). From Monday through Friday, men ingested 330 mL of the beverage with lunch and 330 mL with dinner; women ingested 330 mL with dinner. Before and after the intervention, anthropometry and body composition, through dual-emission X-ray absorptiometry, were measured. No changes in body mass, waist circumference, waist/hip ratio, visceral adipose tissue or bone mineral density occurred in any of the groups. By contrast, in all the training groups, significant decreases in fat mass together with increases in lean mass (all p < 0.05) occurred. These positive effects were not influenced by the regular intake of beer or alcohol. In conclusion, a moderate beer intake does not blunt the positive effect of 10-week HIIT on body composition in young healthy adults.
