Quantificação e elaboração de modelo de predição do gasto energético de homens e mulheres jovens fisicamente ativos nos exercícios resistidos supino reto e leg press /

Magosso, Rodrigo Ferro January 2019 (has links)
Orientador: Vilmar Baldissera / Resumo: Apesar de diversos avanços científicos, mesmo após mais de 200 anos de aplicação da primeira calorimetria com humanos e todas as possibilidades criadas pelas tecnologias desenvolvidas, em especial os aparatos portáteis, o gasto energético (GE) dos exercícios resistidos ainda permanece, de certa forma, elusivo. Desta forma, o presente estudo foi conduzido com o objetivo geral de Quantificar e criar um modelo matemático para a predição do gasto energético de homens e mulheres jovens fisicamente ativos nos exercícios supino reto (SR) e leg press (LP). 11 homens (grupo masculino – GM), com idade (média ± desvio padrão) de 28,7 ± 5,5 anos, altura de 1,77 ± 0,07m, massa corporal de 81,40 ± 8,17kg e percentual de gordura de 16,36 ± 6,79% e 11 mulheres (grupo feminino – GF), com idade de 27,6 ± 4,6 anos, altura de 1,67 ± 0,06m, massa corporal de 60,05 ± 5,76kg e percentual de gordura de 20,20 ± 2,73% se voluntariaram para o estudo. Cada voluntário se apresentou ao Laboratório de Fisiologia do Exercício da UFSCar em oito ocasiões: na primeira visita, os voluntários foram informados sobre os objetivos e procedimentos do estudo, assinaram o termo de consentimento livre e esclarecido, os dados antropométricos mensurados e realizado o ajuste da biomecânica dos exercícios e teste de 1 repetição máxima (1RM) nos exercícios SR e LP. Após 48 a 72 horas, na segunda visita, os voluntários foram submetidos ao reteste de 1RM. Nas seis visitas seguintes, os voluntários foram submetidos ao protocol...

In this sense, the present study was conducted to quantify and create a model to predict EE of young physically active men and women on the bench press (BP) and leg press (LP) exercises. 11 men (male group – GM) with age (mean ± standard deviation) 27.8 ± 5.5 years, height 1.77 ± 0.07m, body mass 81.40 ± 8.17kg and body fat percentage of 16.36 ± 6.79% and 11 women (female group – GF) with age 27.6 ± 4.6 years, height 1.67 ± 0.06m, body mass 60.05 ± 5.76kg and body fat percentage of 20.20 ± 2.73% volunteered for the study. Volunteers came to the Exercise Physiology Laboratory of UFSCar on eight visits: in the first visit, volunteers were informed of the aims and proceedings of the study, signed an informed consent and had their anthropometric data analyzed, biomechanical adjustments made and perform 1 repetition maximum (1RM) test on both exercises. After 48 to 72 hours, volunteers came to the second visit to perform 1RM re-test. In the six following visits, volunteers were submitted to the EE protocol at 40, 60 or 80% of their 1RM on the BP and LP exercises. Interval for evaluations of the same exercise were 48 to 72 hours. GM had a significant difference in total energy expenditure between exercises, but such effect was not observed when EE was quantified as calor...
