Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the study was to determine the effect of isokinetic exercise on heart rate and blood pressure at three different speeds of movement and to determine if an isokinetic interval program had a cumulative effect on heart rate and blood pressure. In addition, the quadriceps and hamstring muscle groups were tested isometrically on the Cybex II isokinetic apparatus. The effects of isometric exercise on heart rate and blood pressure were observed and compared with the results found in previous studies. The data was analyzed using a one-way, two-way, and three-way analysis of variance on repeated measures, and Tukey and Scheffe Tests. Within the confines of the study, the null hypothesis was rejected at the .001 level of confidence for isokinetic exercise at all three speeds used - thirty degrees per second, ninety degrees per second, and 150 degrees per second. The data showed that heart rate increased with both isometric and isokinetic exercise and the increase was larger for isokinetic exercise. Systolic and diastolic blood pressure rose with isometric exercise while systolic blood pressure rose and diastolic blood pressure fell with isokinetic exercise. The increase in systolic blood pressure was greater with isokinetic exercise than with isometric exercise. Modified tension time index, and pulse pressure were higher during isokinetic exercise than during isometric exercise. Mean blood pressure was higher during isometric exercise.

Available in PDF, EPUB and Kindle. Book excerpt: Although the cardiovascular changes associated with dynamic exercise have been investigated, there still remain many unanswered questions with respect to blood pressure following exercise. This study examined the effect of temperature on systolic (SBP), diastolic blood pressure (DBP), heart rate (HR), oxygen consumption $\rm(VO\sb2),$ and skin temperature (Tsk) in 10 healthy, young males (23-28 years of age), during a 60-minute supine post-exercise recovery period. On separate occasions, 20 minutes of treadmill exercise at heart rate of 140 beats per minute, preceded a 60-minute recovery period in a supine position conducted at either $\rm18\sp\circ C,\ 27\sp\circ C,\ or\ 40\sp\circ C.$ Results indicated that mean SBP was significantly more above baseline values at $\rm18\sp\circ C$ than at either $\rm27\sp\circ C\ or\ 40\sp\circ C.$ However, no significant difference in SBP was observed between recovery at $\rm27\sp\circ C\ and\ 40\sp\circ C.$ Also, no significant differences were observed among the three conditions for mean DBP. HR decreased progressively during recovery but remained above baseline values, except at $\rm18\sp\circ C$. No significant differences among recovery conditions were observed for $\rm VO\sb2.$ Mean skin temperatures were significantly different among the three recovery conditions except immediately upon entering the chamber. It was concluded that recovery at $\rm18\sp\circ C$ maintained post-exercise SBP above baseline values while $\rm27\sp\circ C\ and\ 40\sp\circ$C caused a decrease in post-exercise SBP with respect to baseline values. DBP and $\rm VO\sb2$ during recovery were not influenced by temperature. HR decreased gradually post-exercise with the lowest HR observed during cold exposure. Therefore, for the conditions of this experiment temperature had a significant effect on SBP, HR and skin temperature all of which effectively appeared to be associated with peripheral vasodilation/constriction mechanisms.

Download or read book Effects of Different Intensity Bouts of Resistance Exercise But Equal Work on Excess Post exercise Oxygen Consumption written by Milos Galecic and published by . This book was released on 2008 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess post-exercise oxygen consumption (EPOC) is defined as an increase in oxygen consumption (VO2) following the completion of exercise. Previous research has primarily focused on the influence of endurance-type exercise on EPOC. Therefore, the purpose of this study was to compare the effect of a light versus heavy resistance exercise protocol of equal work on EPOC. Ten male subjects performed two days of one-repetition maximum (1-RM) testing and two experimental trials (Light: 3 sets of 15 repetitions at 40% 1-RM; Heavy: 4 sets of 4 to 8 repetitions at 80 to 87.5% 1-RM). VO2, caloric expenditure, blood lactate concentration, heart rate, and blood pressure were measured at baseline, 5, 15, 30, 60, 90 and 120 minutes post-exercise, and 24 hours post-exercise. For both exercise protocols, VO2 and caloric expenditure were significantly greater at 5 min post-exercise compared to baseline. In addition, at 5 min post-exercise, VO2 and caloric expenditure were greater during the light protocol compared to the heavy protocol. During the 120 minutes post exercise, there was no significant difference in EPOC (44.0 ± 43 and 39.1 ± 44.3 mL kg−1; P=0.786) or total caloric expenditure (15.1 ± 13.8 and 12.9 ± 16.9 kcal; P=0.742) between the light and heavy protocols. The data suggests that for resistance exercise protocols with an equal work volume, there is no difference in the magnitude and duration of EPOC.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.
