Flow's Influence On Fatigue During Exercise In Accordance With The Central Governor Model: A review

Posted on March 13, 2016 at 9:10 PM Comments comments (0)

The frontier of human athletic potential resides in understanding the mechanisms which restrain athletes from achieving absolute athleticism. Although there are numerous elements responsible for athletic progress, the most substantial mechanism impeding athletes from reaching ever-higher levels of athletic ability is fatigue. Regardless of the fitness component being stressed (muscular and cardiovascular endurance, strength, or power), fatigue is always the limiting factor. Athlete’...

Athletic development is essential for success in any sport. Regardless of the objective of the sport or the fine motor skills involved, all sports involve some degree of athletic development of their gross motor skills. In the last few years there has been a growing interest in methods used to increase athletic development. Quite recently, considerable attention has been paid to neuromuscular training such as plyometrics, proprioception, and sprint abi...

Cardiorespiratory Fitness: HIIT vs. traditional moderate intensity training. A review

Posted on April 7, 2015 at 9:50 PM Comments comments (0)


Cardiorespiratory fitness is a component of fitness concerned with aerobic capacity, VO2max, and aerobic efficiency. Cardiorespiratory fitness improves with training of the cardiovascular system and respiratory system. The cardiovascular system involves the transport of blood, nutrients, hormones, oxygen, and carbon dioxide throughout the body. The cardiovascular system is governed by the cardiac output of the heart and utilizes arteries, veins, and c...

Exercise physiology is the study of acute and chronic adaptions of the body to exercise. Traditionally exercise physiology has examined the affects of exercise in clinical settings affecting rehabilitation patients but recently more resources have been spent on exercise's effects on athletes. The American Society of Exercise Physiologist best describes exercise physiology as:

“the identification of physiological mechanisms underlying p...

Cardiorespiratory Physiology: Everything from mortality to clearance ability and work capacity. A review

Posted on January 30, 2015 at 3:05 PM Comments comments (0)

Cardiorespiratory physiology encompasses the functions of the cardiovascular system and respiratory system as a synergistic mechanism. The cardiovascular system involves the transport of blood, nutrients, hormones, oxygen, and carbon dioxide throughout the body. The cardiovascular system is governed by the cardiac output of the heart and utilizes arteries, veins, and capillaries for transport of nutrients and removal of waste products throughout the body (Baechle & Earle, 2000, p. 119)....

Endocrinology: Hormonal responses to exercise prescription, nutritional intervention, age, and gender. A review

Posted on January 20, 2015 at 4:25 PM Comments comments (0)

Endocrinology is the study of the endocrine system, which is a collection of secretion glands responsible for transporting hormones to distant organs that influence functions and behaviors. As a sub-discipline of biology, endocrinology is concerned with functions of living organisms ranging from sleep and stress to movement and respiration (Nelson, 2005).

The endocrine system is composed of several glands that secrete hormones directly into the blood rather than into a du...
