O exercício pode se tornar uma experiência prazerosa quando se pode optar pela escolha da intensidade. Logo, O objetivo deste estudo foi investigar o efeito de um programa de exercícios resistidos realizados em intensidade autosselecionada e imposta sobre as respostas perceptuais e afetivas, e carga levantada de 52 adolescentes não treinados (13-17 anos, sexo masculino), em 3 grupos (AS, IMP e CONT). Foram aferidas a Percepção Subjetiva do Esforço (PSE), Escala de Sensação (ES) e a carga levantada após cada série. A estatística utilizou ANOVA One Way para verificar diferenças na maturação, medidas repetidas (AS, IMP, CONT) 3 x 2 (pré e pós programa) para o estado nutricional, e medidas repetidas (AS, IMP, CONT) 3 x 7 (semanas alternadas) para PSE, Escala de Sensação e carga levantada. Não ocorreram diferenças entre os grupos no PVC e no estado nutricional pré e pós (p > 0,05). A intensidade AS proporcionou menores níveis de PSE na maioria das aferições nos 4 exercícios comparadas com IMP (p < 0,05). As ES foram significativamente positivas na intensidade AS em comparação com a intensidade IMP no supino reto, puxada alta e flexora de pernas na maioria das aferições (p < 0,05). Na extensora de pernas mais positivas na intensidade AS na 10ª e 12ª semana (p < 0,01). A carga levantada pela intensidade AS foi menor em comparação a IMP (p < 0,05), e a intensidade AS foi capaz de melhorar a força muscular durante o programa, e os %1RM autosselecionados atingiram os valores recomendados.
