Heart rate, activity, duration, and affect in added-purpose versus single-purpose jumping activities.

چکیده
This research replicates and extends an occupational therapy research project reported by Kircher in 1984. Thirty women aged 18 to 31 years jumped with a rope on one day and jumped in place on another day in a counterbalanced design. Each subject stopped jumping when she reached what she perceived as the very hard level on the Borg Scale of Perceived Exertion (Borg, 1970). Differences from Kircher's design included an imposed target zone formula for safe maximum exertion, use of a portable, more easily read heart rate monitor (Exersentry, Model 3), use of the Osgood Semantic Differential to measure affective meanings, and asking the subjects to identify the type of jumping they preferred. Data analysis supported Kircher's finding that at the given rate of perceived exertion, heart rate increase after jumping rope was significantly higher (p = .01) than after jumping without a rope. The difference in duration of jumping approached significance (p = .06), but in the direction opposite to what Kircher found. There were no significant differences in affective meanings or preference. Results are discussed in terms of the need for a growing body of occupational therapy literature in regard to the purposefulness of activities.

A comparison of performance measures of an added-purpose task versus a single-purpose task for upper extremities.
Occupational therapists often employ multidimensional tasks. These tasks, referred to as added-purpose tasks, provide a person with necessary exercise, yet direct the focus of attention toward another objective or outcome. The assumption is that the additional purpose will result in improved task performance, provided it is sufficiently distracting or meaningful to the person. The present study...

Introduction: Adhesion molecules play an important role in the pathogenesis of atherosclerosis and the type of training may affect the response to these indicators. Therefore, the purpose of the present study was to investigate the effect of a continuous versus interval aerobic training session on plasma levels of intercellular adhesion molecules 1 (ICAM-1) and vascular cell adhesion molecules ...
متن کاملStress and Atherogenesis: Smooth Muscle Cell Mitogenic Activity and other Biochemical Changes Associated with Sera of \"Stressed\" Subjects
The proliferation of smooth muscle cells in the arterial wall (VSMC) is considered to play a key role in the development of atherosclerosis. To investigate the possible contribution of "stress" (experimentally-induced) to this process, blood from healthy volunteers, ages 21 to 65, screened to exclude major risk factors for coronary heart disease, was assayed for mitogenic activity after the sub...
