Cucato, Gabriel Grizzo;Ritti-Dias, Raphael Mendes;Wolosker, Nelson;Santarem, José Maria;Jacob Filho, Wilson;Forjaz, Claudia Lúcia de Moraes;
Clinics , 2011, DOI: 10.1590/S1807-59322011000200007
Abstract: objective: to verify the acute effects of resistance exercise on post-exercise blood pressure in patients with intermittent claudication. methods: eight patients randomly underwent two experimental sessions: a session of resistance exercise (r: 6 exercises, 3 sets of 12, 10 and 8 reps with a perceived exertion of 11 to 13 on the 15-grade borg scale) and a control session (c: resting on exercise machines). results: before and for 60 min following an intervention, auscultatory blood pressure was measured while subjects rested in a sitting position. after the c session, systolic, diastolic and mean blood pressures did not change from the pre-intervention values, while these values decreased significantly after the r session throughout the entire recovery period (greatest decreases = -14 ± 5, -6±5, and -9 ± 4 mmhg, respectively, p < 0.05). conclusion: after a single bout of resistance exercise patients with intermittent claudication exhibited reduced systolic, diastolic and mean blood pressures, suggesting that acute resistance exercise may decrease cardiovascular load in these patients.

Abstract: background: isokinetic dynamometry is becoming increasingly important for the assessment of muscle function in individuals with intermittent claudication. however, there is still little information available about the cardiovascular responses of these patients during this type of assessment. objective: to assess and compare the cardiovascular responses recorded during the assessment of muscle strength and endurance for two exercises commonly used in patients with ic (plantar flexion/dorsiflexion and knee flexion/extension). methods: the sample consisted of 17 claudicant patients with stable disease for at least 6 months. during the isokinetic dynamometer testing, non-invasive measurements of heart rate, blood pressure and double product at rest and at peak exertion were obtained according to specific protocols established for muscle strength and endurance assessment. results: except for diastolic blood pressure, heart rate, systolic blood pressure and double product values rose during the exercise compared to the resting stage (p < 0.05). elevations in heart rate and double product values were higher during knee extension/flexion than during plantar flexion/dorsiflexion (p < 0.05). increases in heart rate were also higher during the endurance assessment protocol than during muscle strength assessment. conclusion: isokinetic strength and endurance testing in patients with ic results in elevation of heart rate, systolic blood pressure and double product values during the exercises. these increases are higher during the muscle endurance exercises and in those involving greater muscle mass, suggesting that strength testing of small muscle groups causes less cardiovascular overload in these patients.

Abstract: the objective of this study was to review the brazilian literature on physical activity/exercise and bone mineral density (bmd)/ osteoporosis. a bibliographic search was performed at lilacs and sibradid databases. the terms "osteoporosis" and "bone density" were combined with "physical activity" and "exercise". original studies that related bmd or osteoporosis with physical activity or exercise in humans, in portuguese and available online were included. seven studies met these criteria and were included in the review. out of three studies that analyzed the association between physical activity practice in childhood and the bmd/osteoporosis, only one found significant association. four out of six studies that analyzed the relationship between actual physical activity/exercise with bmd showed significant relation. the results of this systematic review demonstrated that few studies investigate the relation between physical activity/ exercise and bmd/ osteoporosis in the brazilian literature. although the results present some controversies, they suggest a positive impact on physical activity/exercise to increase bmd and decrease the prevalence of osteoporosis.
