Influences of Exercise Experience and Exercise Settings on Heart Rate Responses During Self-selected Intensity Exercises

Introduction

This study is based on the article Influences of Exercise Experience and Exercise Settings on Heart Rate Responses during Self-Selected Intensity Exercises by Chen-Yi Chu, Shu-Yun Lu and Kuei-Fu Lin. The researcher has focused on the above mention article to make his study more reliable and authenticate. According to this article, one of most applied health promotion strategy is called self selected intensity and this strategy corresponds to a American College of Sports Medicine's recommendation. The main aim of this article was to find the response of heart rate with respect to different exercise of about at least 20 min. It was observed by the experiment that participants had high heart rate in actual field as compared to treadmill activity.

According to many health experts, intensity activities like cycling, dancing, walking, prescribed home exercise and gardening can have important long-term health benefits, such as lowering blood pressure and cholesterol levels and reducing the risk of heart attack, heart disease, stroke and diabetes. The design of an exercise session involves an initial five to ten minute of warm up exercise, that is, stretching and range of motion activities that enable musculoskeletal and circulatory readiness for exercise. A 20 to 40 min endurance component initially involves walk run sequences or exercise on a stationary bicycle or treadmill, for these activities, skill is minimal component of the intensity of work demand. To reap the benefits of physical fitness, experts advise that you do at least 30 minutes of moderate-intensity activities every day (ACSM 2006). In numerous researches, the health benefits of physical exercise are quite evident. Improved fitness results from adaptation and improvement of cardiovascular, respiratory, and metabolic function as well as local responses in the muscle groups engaged (WHO 2003). An important principle to be assimilated at the outset is that intensity is interpreted by the person engaged in the exercise. Beneficial effects of exercise accrue when individuals engage in activity with appropriate frequency, duration and intensity. The interplay of all three dimensions is important, but the determination of appropriate intensity requires earlier consideration because of the impact of numerous variables. One approach to determining intensity is to base judgments on physiological information (ACSM 2006). The usual method is to recommend intensity levels relative to actual or predicted maximal capacity based on measures of heart rate response, oxygen utilization, ventilation and blood lactate.

Self-selected Intensity could be employed as a beneficial health strategy. There has been earlier research to show the efficacies of self selected intensity applications both for medical subjects and the general population, including the sportsmen. The heart rate (HR) response to self intensities in exercise has been found to reflect appropriate levels of exercise, both in outdoor settings such as jogging or running on track and in indoor exercise settings such as the treadmill. Having a close estimate or better still an actual maximal heart rate will greatly increase the ...
