Physical activity, self‐efficacy, and perceived exertion among adolescents

Abstract

The relationship of self-efficacy, a sense of confidence in personal physical activity (PA) skills, to perceived exertion during activity was explored among 168 African American and European American boys and girls between 9 and 17 years of age. Participants walked/ran on a treadmill at a speed equivalent to 60% of their peak VO2 for 20 minutes and provided ratings of exertion every 4 minutes. Pre-activity self-efficacy predicted perceived exertion for boys only. Girls were lower than boys in pre-activity self-efficacy and subsequently reported greater perceived exertion. For both genders, lower perceived exertion during PA resulted in higher post-activity self-efficacy. Uncomfortable perceptions of exertion during initial efforts to increase PA are likely to discourage future activity. Interventions that can lower perceptions of exertion may enhance self-efficacy and promote a sense of competence in PA skills.

Exploring response shift in the quality of life of healthy adolescents over 1 year

“…The lack of a reprioritisation was unexpected given the large body of adolescent development literature that reports considerable changes in many areas related to QoL, such as family and peer relationships [41], physical self-perceptions [22,42] and life goals [9]. However, the findings are consistent with prior research, not directly assessing RS, but which has reported similar stability in the relative importance of domains.…”

Predicted and Actual Exercise Discomfort in Middle School Children

“…The female children's lower level of aerobic fitness may have resulted in higher perceptions of exertion at any given time point during the shuttle run. In a study of 9-to 17-yr-old children performing incremental treadmill exercise, Robbins et al (21) noted that females tended to report greater exertion than males during each of the study periods. They attributed this response to lower fitness levels in the females (21).…”

They attributed this response to lower fitness levels in the females (21). Interestingly, Robertson also noted that when adult males and females performed at the same submaximal exercise intensity, RPE-O was higher for the individuals who had the lower aerobic fitness level (23).…”

Prática esportiva e participação nas aulas de educação física: fatores associados em estudantes de Londrina, Paraná, Brasil

“…A falta de movimentação nas aulas de educação física é um fator comumente relatado por alunos como sendo uma das causas da não participação 40 . Um fato que poderia justificar a realização de au-las com menor movimentação é que a aula com muita movimentação resultaria em aumento da intensidade da atividade, gerando percepções de desconforto durante a realização, o que ocasionaria a desistência da tarefa realizada, como já descrito em jovens 41 . Isso não foi confirmado pelos achados do presente estudo, haja vista que não foram encontradas associações entre se sentir cansado após as aulas de educação física e participação nas mesmas.…”
