Resumos

O objetivo desse estudo foi verificar a influência da adiposidade corporal sobre as respostas fisiológicas e afetivas durante caminhada em ritmo autosselecionado. Foram investigadas 45 mulheres adultas, sedentárias, que foram divididas de acordo com o seu percentual de gordura corporal em baixo tercil (BT, n=15), médio tercil (MT, n=15) e alto tercil (AT, n=15). Todos os participantes foram submetidos a duas sessões experimentais, as quais foram compostas de (I) uma pré-avaliação inicial, avaliação antropométrica e teste incremental máximo em esteira, e (II) um teste de 20-minutos de caminhada em ritmo autosselecionado. As respostas fisiológicas (O2 e FC) foram mensuradas, continuamente, durante toda a realização do teste de 20-minutos de caminhada em ritmo autosselecionado, enquanto a resposta afetiva foi determinada somente a cada intervalo de 5 minutos do teste. Para a análise estatística, empregaram-se análises de variância de um fator (adiposidade corporal), adotando P<0,05. Nenhuma diferença significativa foi verificada, na velocidade de caminhada autosselecionada, entre os grupos experimentais (1,63, 1,60, e 1,47 m.seg-1 para BT, MT e AT, respectivamente), enquanto o %O2max foi significativamente maior em AT (61,8%), comparado à MT (55,8%) e BT (52,8%) (P<0,05). Por outro lado, a resposta afetiva (2,36, 1,80, e 1,85 para BT, MT, e AT, respectivamente) foi similar entre os grupos experimentais. Com base nos resultados expostos acima, sugere-se que a adiposidade corporal pode influenciar as respostas fisiológicas, porém não a resposta afetiva, durante caminhada em ritmo autosselecionado.

The aim of this study was to investigate the influence of adiposity on physiological and affective responses during walking at a self-selected pace. Forty-five sedentary women were divided into three groups according to their percentage of body fat (low tertile, LT, n=15; medium tertile, MT, n=15; and high tertile, HT, n=15). Each participant completed a maximal exercise test and a 20-min bout of treadmill walking at a self-selected pace. The preferred walking speed did not differ between the groups (1.63, 1.60, and 1.47 m.sec-1 for LT, MT and HT, respectively), whereas %O2max was higher in HT (61.8%) compared to MT (55.8%) and LT (52.8%) (P<.05). Nevertheless, affective (2.36, 1.80, and 1.85 for LT, MT and HT, respectively) response were similar between the groups. These findings suggest that adiposity did influence physiological, but not affective responses, during treadmill walking at a self-selected pace in sedentary women.
