RESUMOO estudo analisou o desempenho motor em relação à idade cronológica e ao sexo em amostra representativa de escolares de Montes Claros, Minas Gerais, Brasil. A amostra foi constituída por 2849 sujeitos (1457 raparigas e 1392 rapazes), com idades entre 6 e 18 anos, selecionada aleatoriamente. Os componentes de desempenho motor foram determinados a partir da bateria de teste envolvendo cinco itens: a) sit-and-reach, b) curl-ups, c) trunk-lift, d) push-ups e e) PACER. Os resultados encontrados mostram que, em quase todos os testes motores administrados foram constatadas diferenças intersexos desde os 6 anos que aumentaram drasticamente a partir dos 12-13 anos. Em relação à idade cronológica, os rapazes na maioria dos testes motores administrados apresentaram gradualmente melhores resultados desde os 6 até os 18 anos, enquanto entre as raparigas os resultados mais elevados ocorreram por volta dos 11-12 anos com posterior declínio ou constância de seus escores.

The sample consisted of 2849 subjects (1457 girls and 1392 boys), ranging in age from 6 to 18 years, selected randomly. The motor performance components were determined using a test battery consisting of five items: a) sit-and-reach, b) curl-ups, c) trunk-lift, d) push-ups, and e) PACER. The results show that, in almost all motor tests occurred differences intersexes from 6 years and up which increased abruptly after 12-13 years. In relation to chronological age, boys presented gradually better results from 6 to 18 years in the majority of the motor tests. Girls' best performance occurred around 11-12 years of age followed by a steady performance or a tendency to decline.

“…This finding is also validated by other studies where the total exercise durations were significantly shorter in the obese group compared to the non-obese, in spite of the fact that different authors used different exercise protocols in their respective studies. [13][14][15][16][17][18][19][20][21] Our study also assessed the subjective response to the intensity of the exercise effort through the reported significantly higher perceived exertion among the obese subjects than controls. 14,16,17 This can be due to the fact that obese subjects incur a greater aerobic cost because of their decreased aerobic efficiency which in turn leads to an increased awareness of fatigue that poses a limitation to the exercise effort.…”

There is a general paucity of studies on exercise testing and performance among the various age groups of the Indian population with regard to obesity and cardiovascular fitness. Also such study is sorely lacking among the college students, who belong to the 'young ABSTRACT Background: Cardiovascular fitness has been found to be significantly compromised by obesity, whose prevalence is increasing rapidly. The present study aimed to assess the aerobic exercise performance in terms of maximum aerobic power (VO 2 max) of the male students of North Bengal medical college in the age range of 18-22 years. Methods: The subjects were divided into two groups viz. control (N=52) and study (N=43) on the basis of Body Mass Index (BMI) and Waist Circumference (WC), according to the current Indian guidelines for obesity. The VO 2 max was compared among the two groups. It was evaluated using the Bruce protocol, and also expressed in terms of 'Metabolic equivalents' (MET). Results: VO 2 max exhibited significant negative correlation with BMI (r=0.75, P <0.000) and WC (r=0.72, P <0.000). VO 2 max was higher for the normal group compared to the study group, and the mean difference was significantly different [P <0.05(0.000)]. Conclusion:The study thus showed that cardiovascular capacity is compromised by excess adiposity.
