Abstract
ABSTRACT It has been shown that combined physical exercise is an efficient non-pharmacological approach in the context of public health, since it has demonstrated satisfactory results in the prevention, treatment and control of various morbidities. Therefore, it is essential to systematize current knowledge to enable professionals involved in the prescription of physical exercise to do so based on evidence. Thus, the objective of this study was to perform a systematic review of randomized clinical trials to verify changes in cardiometabolic risk factors induced by high-intensity interval training (HIIT) and resistance training (RT) in adolescents. The systematic search was performed in the following databases: Pubmed, ScienceDirect, Cochrane, LILACS and Scielo. Initially 933 studies were identified, then two researchers eliminated duplications and manuscripts that did not meet the eligibility criteria. Thus, two articles were included that met these criteria: a randomized clinical trial conducted with adolescents (10 to 19 years) of both sexes, an intervention lasting for at least four weeks, which prescribed HIIT and RT in the same session or not, and evaluation of at least one cardiometabolic risk factor. The results demonstrated that eight to 12 weeks of HIIT and RT without nutritional intervention were effective in significantly reducing waist circumference and body fat percentage. However, data pertinent to the efficacy of this combination on risk of developing type 2 diabetes mellitus and arterial hypertension are controversial. In view of the above, it is ascertained from the included studies that the combination of HIIT and RT has the potential to reduce cardiometabolic risk factors in adolescents; therefore, further studies should be conducted to determine the effectiveness of this prescription of physical exercise. Level of Evidence II; Systematic review of Level II or Level I Studies with discrepant results.
Highlights
The increasing prevalence of overweight and obesity has become one of the most serious health problems in the 21st century.[1]
- They were randomized into five groups (HIIT + treinamento resistido (TR), high-intensity interval training (HIIT) + TR, HIIT + TR, HIIT + TR, and HIIT + TR)
Considering the results demonstrated by the articles included in this review, the combination of HIIT and resistance training (RT) has the potential to reduce cardiometabolic risk factors in adolescents
Summary
The increasing prevalence of overweight and obesity has become one of the most serious health problems in the 21st century.[1]. Evidence shows that physical exercise is a non-pharmacological intervention that is effective for reducing the risk of cardiometabolic risk factors.[3,4] Traditionally, continuous aerobic exercise has been the most commonly prescribed owing to its already demonstrated benefits for cardiovascular health and weight control.[4] Considering that lack of time is one of the main barriers to exercise among adolescents,[5] in recent decades, researchers have demonstrated that high-intensity interval training (HIIT) is an efficient method for the development of performance and cardiometabolic health indicators in different populations,[6,7] besides its lower exercise volume and session duration. The literature suggests that HIIT presents similar results[8] or has an even greater effect[9] on these indicators in relation to continuous training
