Perceived exertion in different strength exercise loads in sedentary, active, and trained adults.

The aim was to analyze the relationship between the perceived exertion (PE) and different loads in strength exercises (SEs), in sedentary, active, and trained adult subjects. Thirty young men (18-34 years) were divided into 3 groups (experimental group [EG]): sedentary EG (SEG), physically active group (PAG), and the strength trained group (STG). Maximum strength was established using the 1 repetition maximum test (1RM). Using series of 12 repetitions, different loads were applied until the 4 ratings of PE (RPEs) (11, 13, 15, and 17) from 15 category Borg Perceived Exertion Scale (RPE 6-20). The pace of the repetitions and the intervals between the sets were controlled, the loads were blind, the order of the RPE randomized, whereas the PE was localized and determined after completion of the series. Strength correlations between the RPE and the %1RM, according to the EGs and SEs (0.826-0.922, p < 0.001), were observed. Similar behavior was seen in the SEs. Higher loads are related to higher RPEs and are differentiated between the EGs. The STG used higher %1RM when compared to the SEG, whereas the PAG, displayed an intermediary behavior in relation to the other groups. The use of PE represents a reliable instrument for the measurement of intensity in strength training.

Comparação da força, flexibilidade e resistência de mulheres praticantes de treinamento de força e praticantes de Pole Dance / Strength, flexibility and resistance comparison between woman strength training practitioners and Pole Dance practitioners

Praticar atividade física promove melhora na qualidade de vida e na aptidão física. Neste sentido, o treinamento de força e o pole dance são modalidades que muitas mulheres buscam para melhorar a força, flexibilidade e a resistência abdominal. A partir disso, o objetivo do presente estudo foi comparar a força, a flexibilidade e resistência entre mulheres que praticam treinamento de força e que praticam pole dance. Foram selecionadas 22 mulheres praticantes de treinamento de força (n=11) e de pole dance (n=11). As mesmas foram submetidas ao teste de 1RM de extensão de joelhos, teste de preensão manual com dinamômetro, teste de flexibilidade no banco de Wells e teste de resistência abdominal em 1 minuto. Não foram observadas diferenças significativas para a idade, massa corporal, estatura, IMC e % de gordura entre os grupos avaliados (p>0,05). As praticantes de treinamento de força apresentaram melhores níveis de força de membros inferiores (p=0,026) enquanto as praticantes pole dance melhor flexibilidade (p=0,003). Para preensão manual e resistência abdominal não foram observadas diferenças significativas entre os grupos (p>0,05). Pode-se concluir que o treinamento de força tende a proporcionar maior força de membros inferiores enquanto o pole dance favorece a flexibilidade...(AU)

Physical activity practice promotes improvement of life quality and physical performance. Thus, the strength training and pole dance are exercise forms that many women seek when it comes to strength, flexibility and resistance. The aim of this study was to compare the strength, flexibility and abdominal resistance between women strength training practitioners and pole dance practitioners. Were selected 11 women practitioners of strength training and 11 women practitioners of pole dance. Subjects were submitted to the one maximal repetition test of knee extension, handgrip dynamometer test, flexibility test using bank Wells and abdominal resistance test in one minute. No significant difference was observed for age, body weight, height, body mass index and fat percentage between groups (p> 0.05). The strength training practitioners had higher levels of lower limbs strength (p = 0.026) while pole dance practitioners showed better flexibility (p = 0.003). For handgrip and abdominal resistance no significant differences were observed between groups (p> 0.05). We concluded that the practice of strength training tends to provide greater lower limbs strength while the pole dance favors flexibility...(AU)
