INFLUÊNCIAS DO TREINAMENTO INTERVALADO DE ALTA INTENSIDADE SOBRE A HABILIDADE FÍSICA DO VOLEIBOL

ABSTRACT Introduction: Traditional physical training has a good effect on the improvement of strength and quality indicators of the athletes; however, recent pieces of evidence indicate that relating it to high-intensity interval training may reduce the physical problems of its practitioners, besides accelerating the physical skills required by volleyball. Objective: Study the application of high-intensity interval training on the physical ability of volleyball players. Methods: 40 volunteers were recruited, among freshmen and university students, practicing volleyball. They were divided equally into the control and experimental group. The control group used traditional physical training based on aerobic exercise, while the experimental group adopted a high-intensity interval training program. Each session lasted 1.5 hours, twice a week, for 9 weeks. Relevant physical and functional data were individually collected before and after the intervention, compared, and statistically analyzed. Results: There was an increase in the quality of the long-distance throw, horizontal pull force, 800 m run, 30 m run, cross jump, and repeated crossing experiment. Conclusion: The high-intensity interval training protocol raised the fitness level of volleyball players, allowing optimization of performance on the court.

Effects of a short-term of whole-body, high-intensity, intermittent training program on morphofunctional parameters

BackgroundFew studies have analyzed the application of high-intensity interval training (HIIT) using exercises with body weight among the morphofunctional parameters. AimTo analyze and compare the effects of six weeks of high-intensity intermittent calisthenic training (HIICT) and moderate intensity, continuous exercise (MICT) on body composition, hypertrophy, and strength. Materials and methodsTwenty-five active, healthy adults were randomized in either the HIIT group (n = 14) or the MICT group (n = 11). The HIIT group performed high-intensity intermittent calisthenic training based on full body exercise. The training session involved 5 min of warm-up followed by 20 sets of 30s all-out exercise and 30 s of passive recovery between sets. Jumping jack, mountain climber, burpee and squat jump were used. The MICT group performed continuous moderate running (5 min of warm-up followed by 20 min of running with intensity fixed at 80% of maximum heart rate). Training for both groups was performed three times weekly on nonconsecutive days. All subjects underwent anthropometric measurements and functional tests. Muscle thickness was also measured. ResultsThere were no significant changes observed in any anthropometric measurements in both groups. Regarding the functional tests, the analysis of the percentage changes revealed advantages of HIICT over MICT in push-ups only (p = 0.02). The muscular thickness of lower and upper limbs did not present significant differences in the pre- and post-times or between groups (p > 0.05). ConclusionWhen compared to MICT, HIIT improved push-up effects, without generating significant changes in body composition and muscle thickness.

Feasibility, Safety, Adherence and Efficacy of High-Intensity Interval Training Cardiac Rehabilitation Programs for Patients with Coronary Heart Disease

There are reservations regarding the clinical application of high-intensity interval training (HIIT) in real-world cardiac rehabilitation settings. This study investigated HIIT compared with moderate-intensity continuous training (MICT) within a standard hospital cardiac rehabilitation program. Two hundred and sixty adults with angiographically proven coronary artery disease undergoing a standard 4-week cardiac rehabilitation program were approached. Ninety-three patients were subsequently randomised to: 1) HIIT (n = 46): 4 x 4-minute high-intensity intervals at 15–18 rating of perceived exertion (RPE, range 6–20) interspersed with 3-minute active recovery periods; or 2) MICT (n = 47): usual-care exercise involving 40-minutes of aerobic exercise at 11–13 RPE. Participants completed two supervised sessions and one home-based session per week. Feasibility was assessed using staff and participant questionnaires. The incidence and seriousness of adverse events were recorded to evaluate safety. Adherence to the exercise protocol was assessed from exercise records and self-report logs. Average training RPE was significantly higher for HIIT (16 ± 1 vs 12 ± 1) and resulted in a significant improvement in peak oxygen uptake compared to MICT (+2.9 ± 3.5 vs +1.1 ± 0.0 mL/kg/minute, p = 0.012). There was no difference in the incidence of serious adverse events between HIIT (n = 2) and MICT (n = 2). Adherence to the exercise protocol was high in both groups (HIIT 80% vs MICT 87%). Feasibility scores were equal between groups (98%) regarding desire to continue their randomised training. Staff acceptance of the HIIT program was high. Compared to usual care (MICT), HIIT was safe, feasible, and more efficacious for improving fitness without loss of exercise adherence.

Revisión del efecto del entrenamiento de alta intensidad sobre el rendimiento físico en futbolistas

<p>En los últimos años ha surgido un especial interés en la aplicación de High-Intensity Interval Training (HIT) en las distintas modalidades deportivas. El objeto de este estudio fue revisar sistemáticamente estudios sobre el entrenamiento interválico de alta intensidad y su efecto sobre el rendimiento físico en el futbolista de alto nivel. Para ello, se realizó una revisión sistemática a través de comandos de búsqueda en 4 bases de datos: PUBMED, SCOPUS, SPORTDISCUS y DIALNET. Se estipularon 5 criterios de inclusión: temática acotada del trabajo, actualización, indexación, idioma, grado de profesionalización del contexto deportivo. Un total de 17 estudios de los 243 iniciales resultaron de la revisión. Los datos obtenidos indicaron que la aplicación del entrenamiento interválico de alta intensidad produce efectos positivos en el rendimiento físico de los futbolistas de alto nivel en 14 de las 17 investigaciones. El VO2máx. es el indicador de rendimiento seleccionado en la mayoría de trabajos. HIT, SIT y juegos reducidos son los medios de entrenamiento más utilizados. La duración de los entrenamientos osciló entre los 10 días y 12 semanas. Tras la revisión, se puede concluir que el entrenamiento interválico de alta intensidad se postula como un medio de preparación pertinente para las demandas fisiológicas del futbolista.</p>

Potential Universal Application of High-intensity Interval Training from Athletes and Sports Lovers to Patients.

Recently, high-intensity interval training (HIIT) has received much attention as a promising exercise option not only to improve aerobic fitness, but also to prevent and improve lifestyle-related diseases. Epidemiological studies have shown that the exercise volume, as determined by the product of exercise intensity, duration, and frequency, has been shown to be important for improvements in muscle mitochondrial activity and subsequent improvements in aerobic fitness, insulin sensitivity, and metabolic variables. Therefore, continuous moderate-intensity training has been widely recommended. On the other hand, the main contributor of HIIT to improvements in aerobic fitness and metabolic variables is its high-intensity nature, and many recent studies have shown results favoring HIIT when compared with conventional continuous training, despite its shorter exercise duration and smaller exercise volume. In this review, we aim to show the possible universal application of HIIT in a hospital setting, where athletes, sports lovers, and patients have sought medical advice and have the opportunity to undergo detailed evaluations, including an exercise stress test. For athletes, HIIT is mandatory to achieve further improvements in aerobic fitness. For patients, though higher levels of motivation and careful evaluation are required, the time constraints of HIIT are smaller and both aerobic and resistance training can be expected to yield favorable results because of the high-intensity nature of HIIT.

Physiological adaptations to low‐volume, high‐intensity interval training in health and disease

Exercise training is a clinically proven, cost-effective, primary intervention that delays and in many cases prevents the health burdens associated with many chronic diseases. However, the precise type and dose of exercise needed to accrue health benefits is a contentious issue with no clear consensus recommendations for the prevention of inactivity-related disorders and chronic diseases. A growing body of evidence demonstrates that high-intensity interval training (HIT) can serve as an effective alternate to traditional endurance-based training, inducing similar or even superior physiological adaptations in healthy individuals and diseased populations, at least when compared on a matched-work basis. While less well studied, low-volume HIT can also stimulate physiological remodelling comparable to moderate-intensity continuous training despite a substantially lower time commitment and reduced total exercise volume. Such findings are important given that 'lack of time' remains the most commonly cited barrier to regular exercise participation. Here we review some of the mechanisms responsible for improved skeletal muscle metabolic control and changes in cardiovascular function in response to low-volume HIT. We also consider the limited evidence regarding the potential application of HIT to people with, or at risk for, cardiometabolic disorders including type 2 diabetes. Finally, we provide insight on the utility of low-volume HIT for improving performance in athletes and highlight suggestions for future research.
