hot environment are at risk of heat stress. Circulating blood to the skin and through sweating is the key to get rid of extra heat to balance a stable internal temperature. When the body is not able to cool itself, the body’s core temperature and heart rate increase and several heat-related illnesses could occur [1]. Appropriate clothing is encouraged to wear during working in extreme heat environment. However, protective clothing or equipment could severely impede heat exchange by sweating. In…

AN ATHLETE 'S HEART Everyone knows normal daily exercise is beneficial to the heart. It helps reduce the risk of heart disease, reduces weight, lowers blood pressure, and improves cholesterol. A difference in the appearance of the heart can be seen between normal exercise and those of highly trained athletes. Athletic hearts undergo cardiac remodeling of chambers and physiological changes because the heart is working harder to pump blood to the rest of the body during extreme physical activity…

average reclining heart rate is 69.1 beats per minute, and the average standing heart rate is 82.9 beats per minute. The standard deviation for reclining heart rate is 9.8, and the standard deviation for standing heart rate is 17.8. The average…

You may have witnessed someone struggle with it--a squeeze in the chest, the faster beat of the heart, a shortness of breath that may be accompanied by a wave of dizziness, nausea, or sweating.

This rapid, abnormal heart-related condition is called Atrial Fibrillation, or more commonly known as AFib or AF. It can be caused by a variety of things, including some…

You are a fitness coach and are instructing a personal fitness training session for an athlete in a gym. The session involves cardiovascular and resistance training. Questions: 1. You noticed that heart rate increased immediately before exercise (above resting levels). Why is this the case? Heart rate may increase before the start of any exercise; this is due to an involuntary…

Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…
