Purpose: The purpose of this study was to evaluate the limited efficacy of a high-intensity interval training (HIIT)-based fitness education unit in middle school physical education (PE). Method: The study took place in six PE classes at one middle school located in the southern United States. The authors conveniently assigned the classes to treatment (n = 3 classes; 113 students) or control (n = 3 classes; 119 students) groups. Two trained PE specialists implemented the HIIT lessons two to three times per week for 8 weeks. The authors collected mixed methods data at the student, class, and teacher levels for the evaluation. Results: The focus group teacher interview with the teachers, field observations, and accelerometer-determined in-class physical activity data revealed sound implementation fidelity. The HIIT-based fitness education condition also showed greater improvement in physical activity and fitness knowledge and attenuated decline in curl-up scores compared with the control. Conclusion: The findings support the limited efficacy of implementing HIIT for fitness education in middle school PE programs.

Purpose: This review aimed to evaluate the utility of high-intensity interval training (HIIT) programs integrated into physical education classes. Method: Searches of electronic databases from January 2008 to March 2020. Inclusion criteria: Applied to adolescents aged 10–19 years; applied in school settings; reported results on physical fitness, physical activity (PA), and motivation; at least for 4 weeks; and randomized controlled trials. Studies with adolescents with physical or intellectual limitations were excluded, as well as other interventions parallel to HIIT. Results: Fourteen studies were included. All works present significant improvements in physical fitness and PA. Improvements in body composition recorded, at most, a moderate effect size. HIIT is presented as a powerful stimulus on cardiorespiratory fitness. Improvements in PA registered, a least, a moderate effect size. Conclusions: HIIT in the school context has great potential in improving physical fitness and PA in adolescents. HIIT efficiency (about 10 min) reflects the wide applicability that these protocols can have in physical education classes and great adaptation to the facilities.

Abstract Background: Little is known about children’s experience with high-intensity interval training (HIIT) during elementary school. Perceptions of enjoyment, perceived competence, and motivation are likely to drive long-term adherence and are, therefore, critical to understanding how HIIT might be implemented in this setting. The purpose of this study was to describe children’s physical activity levels, enjoyment, and perceived competency of HIIT activities within a Self-Determination Theory (SDT) framework (autonomy) in elementary school physical education (PE) classes. Methods: Participants were 402 children from a single, diverse elementary school (49.4% female, 59.6% Non-Hispanic white). Student enjoyment and perceived competency were collected following teacher- (non-autonomous) and student- led (autonomous) conditions. A sub-set of 201 children wore accelerometers to measure percent of time in moderate-to-vigorous physical activity (MVPA). This mixed factorial design was assessed through a series of repeated measures ANOVAs. Results: While children reported generally positive enjoyment and perceived competence in both condition (rating over 4.0 on a 5-point scale), children significantly enjoyed (d = 0.44) and felt more competent (d = 0.12) during the autonomous HIIT condition compared to the nonautonomous HIIT condition. In contrast, the percent of time in MPVA (d=1.09) was significantly lower in the autonomous condition. Conclusions: These data illustrate a challenging trade-off with the design of HIIT trials. Increasing autonomy through the inclusion of student choice increased enjoyment and perceived competence of HIIT, which are likely to improve adherence, but lowered physical activity intensity, which is likely to reduce impact.

Physical activity has the potential to reduce cardiometabolic risk factors but evaluation of different intensities of physical activity and the mechanisms behind their health effects still need to be fully established. This study examined the effects of sedentary behaviour, light-intensity training, and high-intensity interval training on biometric indices, glucose and lipid metabolism, inflammatory and oxidative stress markers, and vascular and cardiac function in adult rats. Rats (12 weeks old) were randomly assigned to 1 of 4 groups: control (CTL; no exercise), sedentary (SED; no exercise and housed in small cages to reduce activity), light-intensity trained (LIT; four 30-min exercise bouts/day at 8 m/min separated by 2-h rest period, 5 days/week), and high-intensity interval trained (HIIT, four 2.5-min work bouts/day at 50 m/min separated by 3-min rest periods, 5 days/week). After 12 weeks of intervention, SED had greater visceral fat accumulation (p < 0.01) and slower cardiac conduction (p = 0.04) compared with the CTL group. LIT and HIIT demonstrated beneficial changes in body weight, visceral and epididymal fat weight, glucose regulation, low-density lipoprotein cholesterol, total cholesterol, and mesenteric vessel contractile response compared with the CTL group (p < 0.05). LIT had significant improvements in insulin sensitivity and cardiac conduction compared with the CTL and SED groups whilst HIIT had significant improvements in systolic blood pressure and endothelium-independent vasodilation to aorta and mesenteric artery compared with the CTL group (p < 0.05). LIT and HIIT induce health benefits by improving traditional cardiometabolic risk factors. LIT improves cardiac health while HIIT promotes improvements in vascular health.

Аннотация. В статье рассматривается вопрос улучшения показателей уровня физической подготовленности студентов высших учебных заведений не физкультурных специальностей в возрасте 17–18 лет. Разработано и представлено содержание методики интенсивно-интервального тренинга для оптимизации процесса физического воспитания студентов на занятиях физической культурой, а также комплекс упражнений по системе интенсивно-интервальной тренировки. На основе результатов педагогического эксперимента доказана гипотеза о том, что применение средств интенсивно-интервального тренинга на занятиях физической культурой со студентами высших учебных заведений нефизкультурных специальностей способно значительно повысить уровень их физической подготовленности и степень развития базовых физических способностей. Доказательство эффективности применения средств интенсивно-интервального тренинга для повышения уровня физической подготовленности этих студентов определяет новизну проведенного авторами исследования, обогащение теории физической подготовленности студентов, в том числе развития таких физических качеств, как выносливость, сила и координация движений. Выявляется также его теоретическая значимость, а возможность практического использования педагогами в процессе организации и проведения занятий по физической культуре свидетельствует о практической ценности. The article focuses on the issue of improving physical fitness and stamina of 17–18-year-old non-athletic students of higher education institutions. The author of the article has developed and presents a high-intensity interval training program aimed at enhancing students’ physical fitness through HIIT workouts during physical education classes in higher education institutions. The results of pedagogical experiment prove the hypothesis that HIIT workouts during physical education classes in higher education institutions help enhance non-athletic students’ physical fitness and improve their physical abilities. The fact that high-intensity interval training workouts help enhance students’ physical fitness, stamina, motor coordination and muscular strength accounts for the novelty and theoretical significance of the research. The practical significance of the research is accounted for by the fact that its results can be used by classroom teachers to plan physical education lessons in higher education institutions.

Physical education classes often fail to include sufficient exercise intensity to induce changes in body tissue composition and physical fitness. Short-term high-intensity interval training protocols incorporated into physical education lessons are one possible solution to this problem. Existing studies have not examined how individuals differing in body mass index (e.g., normal-weight, underweight) respond to high-intensity interval training exercises. Therefore, this study aimed to evaluate the effects of a Tabata protocol on body composition measurements, aerobic capacity, and motor performance in underweight and overweight adolescents (the experimental groups) vs normal-weight adolescents (here regarded as the control group). The sample included 58 adolescents (28 boys, mean age = 16.2 years; 30 girls, mean age = 16.2 years) who completed the high-intensity interval training and the following set of measurements pre- and post- intervention: height, weight, body fat percentage and waist-to-hip ratio, physical efficiency index (based on the Harvard Step Test), agility (in 4 × 10 shuttle run test), and lower-limb muscle power in vertical jump. The results showed that high-intensity interval training was effective in reducing body weight, waist-to-hip ratio, and body fat percentage only in overweight individuals. Improvement in aerobic capacity was found only in underweight and overweight boys. Further research should focus on the development of customized exercise protocols and their adaptation to girls and assess the sustainability of the changes induced.
