Effects of high intensity intermittent training in adults with obesity

Abstract

Introduction.High-intensity interval training has become an important tool for weight loss in people who are overweight and obese, since it is based on the execution of exercises in short periods, which can range from seconds or even minutes, carried out at high intensity, followed by rest periods between each exercise series that prove to be very effective in reducing fat. Objective: To establish the effects of a high intensity intermittent training program in obese subjects. Materials and methods. Quantitative study of quasi-experimental design of pretest and posttest, in which 10 obese users participated, which were randomly divided into a control and experimental group. A high intensity intermittent training program was applied for 3 months with a total of 48 sessions and 120 minutes application time. Once the program was completed, the subjects were evaluated again. Results. Statistically significant differences (p<0,05) were found when comparing the average range of related samples in the variables weight (p=0,017) BMI (p=0,029) and VO 2 (p=0,038) of the experimental group. However, despite presenting positive changes in the same variables of the experimental group, these were not statistically significant. Conclussion. The results of the study showed a positive effect of Intermittent High Intensity Training on body weight, body mass index and maximum oxygen consumption. Likewise, it is concluded that this type of training is a good intervention strategy for people with obesity. RESUMENIntroducción. El entrenamiento intermitente de alta intensidad se ha convertido en una herramienta importante en el tratamiento de personas con sobrepeso y obesidad. Esta técnica, que se basa en la realización de ejercicios en períodos cortos (desde segundos hasta minutos) a alta intensidad seguidos de periodos de descanso entre cada serie de ejercicio, resulta ser muy eficaz en la reducción de grasa. Objetivo. Establecer los efectos de un programa de entrenamiento intermitente de alta intensidad en sujetos con obesidad. Materiales y métodos. Estudio cuantitativo de diseño cuasi experimental pretest y postest en el que se incluyeron 10 pacientes con obesidad. Los participantes se dividieron de forma aleatoria en un grupo control y uno experimental. A este último se le aplicó un programa de entrenamiento intermitente de alta intensidad durante 3 meses con un total de 48 sesiones y tiempo de aplicación de 120 minutos. Una vez culminado el programa, los sujetos fueron evaluados de nuevo. 76Rev Col Med Fis Rehab Montealegre-Suárez DP, Romaña-Cabrera LF Resultados.

Effects of high intensity intermittent training on lipid profile and blood glucose overweight/obese university students

“…Authors such as Louzada and Cols 10 reveal that exercise plays an essential role in fat management. Therefore, High-Intensity Interval Training (HIIT) involves developing exercises in short periods with high intensity, followed by periods of rest between the series of exercises performed [11][12] and is considered an important tool to combat obesity, as it increases the benefits of aerobic work in less time 13 . Therefore, the present work aimed to identify the effects of high-intensity intermittent training on lipid and glucose profiles in overweight and obese college students.…”
