Physical Education: Effect of Phototherapy

Introduction

The overall impact of increased intensity has a major impact on a number of factors, such as heart rate, temperature, skin color, sweating, breathing rate, and recovery. The most evident element, which is in a tight correlation with the stress level, is heart rate. The observational analysis indicates that beats per minute measurements start from a base level of 114 and increase up to 180. The body temperature was measured pre-exercise and post-exercise, and it stayed the same at 36.6C. Skin color also underwent significant changes beginning with normal coloration and undergoing light pink and pink colorations as the intensity progressed.

Main body

It is important to note that sweating never reached high levels, but a moderate degree could be observed during the stress level of 18. The breathing rate also went in accordance with intensity, where a low value was assigned for normal rate, and high deeper breathing was seen at level 18. Therefore, it is evident that the given bodily changes were normal reactions to increased physical exercise intensity. Heart rate elevates in order to pump more blood to muscles, which are being deprived of vital elements, such as oxygen and glucose. It is stated that the heart rate and its variability is primarily impacted by physical exercise intensity values (Michael et al., 2017). Although the temperature was measured only pre-exercise and post-exercise, it is clear that there was an unmeasured increase during the exercise.

However, its effect is severely minimized by sweating, which plays an essential role in ensuring that the body loses the accumulated heat through sweat. The given process is assisted by blood vessel vasodilation, which manifests itself in a pinker color of the skin. In addition, it greatly helps in the heat loss process, where dilated vessels increase the overall surface area from which heat can be transferred to out layers of skin and leave the body through sweat. The breathing rate also increases significantly because intensity deprives the most critical element, which is oxygen. Muscles can function in both aerobic and anaerobic ways, where the former is more efficient than the latter, which is why the body counteracts oxygen depletion through increased breathing.

The recovery time is also an important measurement that can indicate the overall condition of the body. One should be aware that activities that are done by the subject prior to testing can heavily impact his or her recovery period (Leal-Junior et al., 2015). These might include sleep deprivation, nutrition, or other exercises. In addition, it is also essential to factor-in one’s training status because individuals who are well-trained might possess better recovery periods compared to untrained people. In the given case, the subject had minimal training of 4 weeks and had a pre-existing injury. However, these factors did not substantially diminish the recovery process because the person is actively involved in soccer and plays the game in a regular manner. Soccer itself is an activity that is comprised of short irregular sprints and light running, and thus, it explains why the subject recovered quicker than expected.

Conclusion

Therefore, it is evident that the intensity of an exercise directly influences one’s heart rate, breathing rate, skin coloration, sweating, and recovery. Although these are considered to be normal bodily reactions to physical activity, it is important to note that they play important regulatory roles. Sweating and skin color change are related to temperature regulation, whereas the heart and breathing rate are in charge of delivering vital elements to active muscle tissues.
