Resumo
Objetivo: A presente dissertação de mestrado teve como objetivo principal estudar
as diferenças entre o High Intensity Power Training (HIPT) e o High Intensity Interval
Training (HIIT) a respeito da frequência cardíaca (FC), dispêndio energético (DE) e escala de
perceção de esforço (RPE). Método: Efetuou-se uma revisão sistemática de literatura (RSL)
com o objetivo de examinar o que a ciência apresenta sobre os dois protocolos. À posteriori
realizou-se um estudo observacional onde os participantes realizaram uma sessão de cada tipo
de protocolo de treino, com o objetivo de perceber se existiriam diferenças entre as variáveis:
FC, DE e RPE. A amostra foi constituída por 20 participantes saudáveis (H: 11; M: 9) com
experiência em treino de alta intensidade, com um Vo2máx médio de 40,1 ml kg-1 min-1.
Resultados: Os resultados do estudo observacional foram ao encontro da RSL na variável
FCméd, em que o HIPT apresentava valores superiores significativos ao HIIT, 89,4 ± 5,7% e
85,4 ± 5,9%, respetivamente. Mas ao nível do DE/min, 14,5 ± 3,1kcal/min versus 14,0 ±
4,6kcal/min, e da RPE, 8,8 ± 0,6 versus 8,6 ± 0,6, apesar dos valores de HIPT serem
superiores, não são valores estatisticamente significativos. De salientar que não foi
encontrado nenhum artigo da RSL que compara os dois métodos com a mesma população. No
método de HIPT os valores vão ao encontro da RSL em todas as variáveis e em HIIT
também. De acrescentar que em HIIT conseguiram resultados idênticos utilizando exercícios
com o peso de corpo e barra livre. Conclusões: Os dois métodos são uma alternativa para se
conseguir um elevado DE/min e valores elevados de FC, tanto média como máxima (HIPT:
97,4 HIIT: 96,9 ± 4,5%), em apenas 12 minutos de exercício (HIPT) e 20 minutos
intervalados (HIIT), com o mesmo tempo de exercício.
Objective: the present master dissertation has the main goal to study the differences between High Intensity Power Training (HIPT) and High Intensity Interval Training (HIIT) regarding the heart rate (HR), caloric expenditure (CE) and scale of perception of effort (RPE). Method: The purpose of the systematic review (SR) was to examine the science behind this two themes. Beforehand, there was an observational study were each participant entered a training session of each method in order to realize if there were differences between the variables: HR, CE and RPE. The samples were constituted by 20 healthy participants (H: 11; M: 9) with experience in high intensity training with average Vo2máx of 40,1 ml kg-1 min-1. Results: The results of the observational study go along with the RSL in regards to the average heart rate, where the HIPT presents significantly superior values in comparison to HIIT 89,4 ± 5,7% and 85,4 ± 5,9%, respectively. However, when it comes to CE/min, 14,5 ± 3,1kcal/min versus 14,0 ± 4,6kcal/min, and the RPE, 8,8 ± 0,6 versus 8,6 ± 0,6, and although he values are superior, they aren't significant statistical differences. It's important to emphasize that neither of the articles in the SR compare the both methods with the same population. In both methods HIPT and HIIT the values go along with the SR in all variables. In addition, the HIIT was able to achieve similar results when using the bodyweight and barbell. Conclusion: Both methods are an alternative to achieve an high CE/min and high values of HR, either the average and the maximum (HIPT: 97,4 HIIT: 96,9 ± 4,5%), in just 12 minutes of exercise (HIPT) and 20 minutes intervals (HIIT), with the same exercise time.
