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.

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.

The Impact

Essential hypertension is a frequent diagnosis in power sports athletes, heavy weight categories. The aim of the study: To evaluate the impact of high-intensity aerobic work on blood pressure and oxidative abilities of hypertensive athletes of power sports, heavy weight categories. Rеsеarсh mеthods: Examination and physical rehabilitation were conducted in 55 hypertensive representatives of power sports, heavy weight categories comparable in age, sex and main clinical manifestations. Athletes were randomized into two groups: the main group (n=35) and the control group (n=20). Athletes of the main group were trained for 180 days (3 times a week) on an ergometer using a high-intensity interval protocol, while the control group participants were trained for 180 days (3 times a week) using their traditional power protocol. The tasks were performed using the following methods: examination, polling, gasometric analysis, triple blood pressure measurement, muscle tissue oxygenation level measurement and mathematical statistics methods. Rеsults: After 180 days of physical rehabilitation, the participants in the main group had a 148% reduction in oxygen oxygenation, an increase in capacity and working time at maximum oxygen consumption, and a reliable decrease in blood pressure: systolic blood pressure by 8.0%, diastolic blood pressure by 10.8%. Сonсlusion: Our protocol for physical rehabilitation of power sports athletes allows us to effectively and safely influence the oxidative capacity of working muscles and blood pressure.

Abstract Background Interventricular interactions in increased RV afterload such as hypoxia stress, which affects both synchrony and function in an in-series effect as well as a parallel effect arising from leftward septal shift. Improved myocardial contractility is a critical circulatory adaptation to exercise training, however, the types of exercise that can improve interventricular synchrony under hypoxic environment have not yet been established. Purpose This study investigates how high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) influence on the interventricular synchrony in response to normobaric hypoxia in sedentary men. Methods Fifty-four sedentary males were randomized to perform HIIT (3-minute intervals at 40% and 80% VO2peak, n=18), MICT (sustained 60% VO2peak, n=18) for 30 minutes/day, 5 days/week for 6 weeks and the control group (CTL, n=18). Synchrony measurements at apical 4-chamber view including (1) intra-delay, the difference in time to peak strain (TS) between segmental septal-to-lateral ventricular or atrial walls, and (2) inter-delay, the difference in TS between RV or RA free wall and LV or LA lateral wall. The data were acquired by 2-dimensional speckle tracking echocardiography at rest under hypoxic condition (12% FIO2, simulated an altitude of 4,500 m) before and after the interventions. Results HIIT had significantly elevated radial and longitudinal strains in both LA and LV (p<0.05). As the results showed, HIIT was superior than MICT in improvement of longitudinal intra-delay of LV; furthermore, only HIIT simultaneously ameliorated both radial and longitudinal synchrony at apex. Although the HIIT enhanced intraventricular synchrony in both motions, whereas the interventricular synchrony deteriorated at radial motion. In atrium synchrony, although both groups augmented the intra-LA synchrony, however, only HIIT reduced the inter-delay between LA and RA at the roof motion. LV end-systolic volume (ESV) significantly correlated with the longitudinal inter-delay of ventricle (r=−0.53, p<0.05), whereas the LV end-diastolic volume (EDV) correlated with the inter-delay of atrium in roof motion (r=0.40, p<0.05). Conclusion We found differences between HIIT and MICT in segmental intra- and inter- synchrony. HIIT enhanced both ventricular or atrial synchrony, and further increased the EDV coupled with decreased ESV. These findings give new insight into cardiac adaptation to difference endurance training and the long-term impact of such changes warrants future study in cardiac diseases.

The ability to process goal-related visual information while ignoring goal-irrelevant information is essential for the human attention system. The study aimed to investigate how perceptual–cognitive performance was affected during high-intensity interval training (HIIT) using a 3D-multiple object tracking (3D-MOT) task called Neurotracker (NT). In an experimental design, 42 healthy adults (age M = 23.3 SD = 2.94, VO2max 52.8 ± 5.66 mL·kg−1·min−1) were randomly assigned to an intervention (HIIT + NT, NT, HIIT) or control group. NT performance (20 trials per session) was measured pre-and post-test (at 5, 15, and 25 min while running on the treadmill). The participants trained twice a week for a 4-week intervention period. There was a significant interaction effect between pre/post-test and groups regarding perceptual-cognitive performance, indicating similar enhancements in the HIIT + NT and the NT group during exercise. HIIT influences physical fitness but did not show any impact on perceptual–cognitive performance. Due to the specific NT task characteristics, improved physical abilities may not directly impact sport-specific perceptual-cognitive performance. Our findings suggest that training resulted in substantial task-specific gains. Therefore, combination training may be proposed as a training program to improve perceptual–cognitive, and physical performance in a time-efficient way.

Purpose:To examine the effect of low-volume sprint interval training (SIT) on the development (part 1) and subsequent maintenance (part 2) of aerobic fitness in soccer players.Methods:In part 1, 23 players from the same semiprofessional team participated in a 2-wk SIT intervention (SIT, n = 14, age 25 ± 4 y, weight 77 ± 8 kg; control, n = 9, age 27 ± 6 y, weight 72 ± 10 kg). The SIT group performed 6 training sessions of 4–6 maximal 30-s sprints, in replacement of regular aerobic training. The control group continued with their regular training. After this 2-wk intervention, the SIT group was allocated to either intervention (n = 7, 1 SIT session/wk as replacement of regular aerobic training) or control (n = 7, regular aerobic training with no SIT sessions) for a 5-wk period (part 2). Pre and post measures were the YoYo Intermittent Recovery Test Level 1 (YYIRL1) and maximal oxygen uptake (VO2max).Results:In part 1, the 2-week SIT intervention had a small beneficial effect on YYIRL1 (17%; 90% confidence limits ±11%), and VO2max (3.1%; ±5.0%) compared with control. In part 2, 1 SIT session/wk for 5 wk had a small beneficial effect on VO2max (4.2%; ±3.0%), with an unclear effect on YYIRL1 (8%; ±16%).Conclusion:Two weeks of SIT elicits small improvements in soccer players’ high-intensity intermittent-running performance and VO2max, therefore representing a worthwhile replacement of regular aerobic training. The effectiveness of SIT for maintaining SIT-induced improvements in high-intensity intermittent running requires further research.

Objectives: To use a quantitative approach to examine the effects of high-intensity interval training (HIIT) interventions on sleep for adults. Methods: PubMed, Ebsco, Web of Science, Cochrane Central Register of Controlled Trials, the China National Knowledge Infrastructure, and Wanfang Data were searched from their inception to December 2020. Intervention studies with a control group that examined the effects of HIIT interventions on sleep were included in this meta-analysis. The risk of bias was assessed using the tool provided by the Cochrane Handbook for Systematic Reviews of Interventions. Effect sizes (ESs), calculated as weighted mean difference (WMD) and standardized mean difference (SMD), were used to examine the effects of objective outcomes and subjective outcomes separately. Results: A large increase in sleep quality (SQ) reflected by the Pittsburgh Sleep Quality Index global scores [WMD = −0.90, 95%CI (−1.72, −0.07), p = 0.03, n = 8] and a small-to-medium favorable effect on sleep efficiency (SE) [SMD = 0.43, 95%CI (0.20, 0.65), p = 0.0002, n = 10] were found after HIIT intervention. In addition, sub-analyses results suggest that ESs were moderated by the type, duration and frequency, as well as the length of the HIIT intervention. Conclusions: HIIT may be a promising way to improve overall subjective SQ and objective SE. PROSPERO, protocol registration number: CRD42021241734.

Physical training is used in the control of arterial hypertension (AH), especially in patients with higher levels of blood pressure (BP). However, there are still few studies on the effects of physical training on AH in less advanced stages of the disease. The aim of the present study was to assess the immediate and late acute effects of continuous moderate physical training (CMT) and high intensity interval training (HIIT) in patients with mild AH, and to assess which training method induces a greater hypotensive effect. A female patient, 43 years old, sedentary, diagnosed with mild AH (stage 1), taking Losartana 50 mg twice a day was studied. She underwent one CMT and one HIIT session, one week apart. BP measurements were taken before and after each session, as well as 24 hours before and after the sessions. After the physical training sessions, we observed a drop in the patient's BP that lasted up to 60 minutes, and a reduction in blood pressure levels on the day after the training. We conclude that both training modalities were efficient in reducing the BP of the patient with mild acute immediate and delayed hypertension.
