The aim of this study was to investigate the relationship between physical fitness and the indicators of quality of life in individuals with intermittent claudication (IC). Forty-two subjects (65.2 ± 8.3 years) with IC of both genders participated in the study. Exercise treadmill test, to assess claudication distance (CD) and total walking distance (TWD), and one repetition maximum knee extension test were used to evaluate physical fitness. The quality of life indicators were obtained from the Medical Outcome Study Questionnaire Short Form, which is composed of eight domains: physical functioning (PF), physical aspects (PA), pain, general health, vitality (VI), social functioning (SF), emotional aspects (EA) and mental health. For statistical analysis Pearson correlation coefficient was used, with p < 0.05. There was a significant correlation between PF and CD and TWD (r = 0.60, p < 0.01 and r = 0.49; p < 0.01, respectively), between RP and TWD (r = 0.46, p < 0.01), between VI and SF and CD (r = 0.34, p = 0.03 e r = 0.33, p = 0.04; respectively), and between EA and CD and TWD (r = 0.43, p = 0.01 and r = 0.44, p = 0.01; respectively). In conclusion, the results of this study suggest that indicators of quality of life, both related to physical health and emotional health, are correlated with the walking capacity in patients with IC.
Abstract:Objective: to analyze the post exercise cardiovascular effects of different resistance exercise protocols for trunk and upper limbs. Methods: Fifteen males (22.3 ± 0.9 years) underwent three experimental sessions randomly: control session (C), resistance exercise session at 50% of one repetition maximum (1-RM) (E50%), and resistance exercise session at 70% of 1-RM (E70%). Three sets of 12, 9 and 6 repetitions were performed for each exercise. Blood pressure (BP), heart rate (HR) and rate pressure product (RPP) were measured before and during 90 minutes after each session. Results: Systolic BP decreased (P<.05) and diastolic BP increased (P<.05) similarly after C, E50% and E70%. However, HR and RPP decreased after C (P<.01), maintained after E50%, and increased after E70% (P<.01). Conclusions: The resistance exercise intensity did not influence post-exercise BP responses, however, cardiac overload was greater after E70%. Key Words: Resistance Training. Blood Pressure. Cardiovascular System.
Efeito de diferentes protocolos de exercício de força para o tronco e membros superiores nas respostas cardiovasculares pós-exercícioResumo: Objetivo: Analisar o efeito de diferentes protocolos de exercício de força para o tronco e membros superiores nas respostas cardiovasculares pós-exercício. Métodos: Quinze homens (22.3 ± 0.9 anos) realizaram três sessões de exercício de força para tronco e membros superiores aleatoriamente: sessão controle (C), sessão de exercício de força a 50% de 1-repetição máxima (1-RM) (E50%) e sessão de exercício de força a 70% de 1-RM (E70%). Foram realizadas três séries de 12, 9 e 6 repetições, respectivamente, para cada exercício. A pressão arterial (PA), a frequência cardíaca (FC) e o duplo produto (DP) foram medidos antes e durante 90 minutos após cada sessão. Resultados: a PA sistólica diminuiu (P<.05) e a PA diastólica aumentou (P<.05) de forma semelhante após C, E50% e E70%. Entretanto, a FC e o DP diminuíram após C (P<.01), mantiveram-se após E50% e aumentaram após E70% (P<.01). Conclusão: A intensidade do exercício de força não influenciou a resposta da PA pós-exercício, contudo, a sobrecarga cardiovascular foi maior após E70%. Palavras-chave: Treinamento de resistência.
