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.
OBJECTIVE: To analyze the acute effect of rest interval length on cardiovascular response after resistance exercise. METHODS: Twenty young eutrophic men (23.9 ± 0.7 years;23.8 ± 0.5 kg/m²) performed two experimental sessions in a random order: resistance exercise with a 30-second (I30) and with a 90-second (I90) rest interval between sets. Both sessions included five exercises with 50% of the one-repetition maximum. Before and 24 hours after the experimental sessions, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and rate-pressure product (RPP) were obtained. RESULTS: The SBP, DBP and RPP responses were similar between the I30 and I90 sessions (p>0.05), while the HR after I30 was significantly higher than after I90 (p<0.01) for the first hour after exercise. The cardiovascular responses during the first 24 hours were similar between both sessions (p>0.05). CONCLUSION: Different recovery intervals did not promote post-exercise hypotension, however, a short rest interval increases heart rate for 1 hour after exercise. In addition, within 24 hours of the responses were similar between groups.
AGRADECIMENTOS À Deus, pela saúde, por tantas bênçãos e por me manter firme ao longo dessa jornada. À minha querida esposa, Manuele, por me aconselhar e estar presente em todos os momentos, nos mais fáceis e, principalmente nos mais difíceis, me apoiando e incentivando. Certamente, não seria possível desenvolver esse trabalho sem sua companhia. Obrigado por aguentar meu mau humor e estresse durante esses 4 anos de doutorado. Então, essa tese também é sua! Te amo demais! Aos meus amados pais, Ricardo e Ione, e meu irmão, Cadinho, por todo incentivo e apoio incondicional, não só durante o doutorado, mas também ao longo de toda minha jornada acadêmica. Essa tese só existe por conta de todo carinho, amor e orações investidos por vocês! Obrigado porque apesar de toda saudade e distância, vocês foram meu porto seguro durante todos esses anos. Amo vocês. À minha segunda mãe e sogra, Marluce, e ao meu cunhado, Pedro, por todo amor, incentivo e hospitalidade, além dos incríveis almoços baianos. Tenho vocês guardados no meu coração, obrigado por todos os conselhos! À minha orientadora, profa. Cláudia Forjaz, pela oportunidade de poder fazer parte do LAHAM e acreditar nesse projeto desafiador. Além de todo o suporte técnico e científico, sendo sem dúvidas um exemplo de orientadora e acima de tudo, um exemplo de profissional dedicada. Ao prof. Raphael Ritti Dias, por ter me aceitado como aluno ainda na iniciação científica, o que modificou e abriu completamente minha mente para a ciência. Além disso, agradeço por sua parceria e conselhos que contribuíram para o meu crescimento acadêmico e chegada até o doutorado. Aos amigos do grupo da claudicação, principalmente Natan, Marcel e Beto Burns, que contribuíram bastante para o desenvolvimento desse trabalho, durante as coletas e análise de dados. Certamente, finalizar esse trabalho sem a ajuda de ambos não seria possível.
