Open-loop controlled 1. The main difference between the ideas of open-loop controlled movements and closed-loop controlled movements is in the consideration of the further steps. According to the theory of the open-loop controlled movements, the first movement is done consciously while all other ones are completed automatically, as the reaction to the first movement. These […]

Introduction Stress forms an integral part of our daily life despite negative notions people have developed against it. According to Wein (2000), stress ensures that the body functions optimally particularly when responding to adverse situations. He further explains that the flight or fight response guarantees individual’s safety since the body is able to react swiftly […]

Introduction In recent years, the concept of whole body maximal oxygen uptake (VO2max), which basically reflects the integrative capability of the lungs, heart and circulatory system to distribute oxygen (O2) to the tissues and eventually mitochondrial O2 utilization (Layec & Richardson 2012), has interested scholars and exercise physiologists for varied yet interrelated reasons (Moxnes & […]

Introduction When people lack real facts concerning some issues, they develop mythical theories which aim at accounting for them. These speculations are based on religion, culture, and misconceived understanding which aim at closing the gap that exists when those issues are not explained.

Introduction It is a well known fact that respiratory rates increase during moments of physical activity yet it must be noted that the subsequent increase in the amount of heartbeats per second differs from person to person (Drury, 2011). As explained by Santtila, Keijo, Laura & Heikki (2008), the average adult heart beats at roughly […]

Teratology is the study of physiological defects in organisms. The defects could be due to several factors like the environmental factors. These factors work together to impair the normal development of an embryo. The level of vulnerability to these defects depends on several factors like the stage of development of an embryo at the time […]

According to Fredrick Hatfield, the abdominal wall is made up of four muscles. These include internal oblique muscles, external oblique muscles, transverse abdominis and rectus abdominis (Hatfield, 2010).
