Anatomy Flashcards
exercise physiology
provides an understanding of how the body responds to the acute and chronic demands placed on it by the increased energy demands of exercise
physical activity
any bodily movement that comes about from the contraction of skeletal muscle and that increases energy expenditure
exercise
a more structured form of physical activity that has a specific purpose in mind
4 Major components of physical fitness + 1
Muscular fitness, cardiovascular/cardiorespiratory endurance(aerobic fitness), Flexibility, Body composition—- Mind/body vitality
cardiorespiratory endurance
the capacity of the heart and lungs to deliver blood and oxygen to the working muscles during exercise
carbohydrates and fatty acids are converted into what for muscular contraction
adenosine triphosphate (ATP)
3 basic processes that must interact to provide adequate blood and nutrients to the tissues-
1- get oxygen to blood through a function of pulmonary ventilation
2- delivering oxygen to the active tissues, a function of cardiac output
3- extracting oxygen from the blood to complete the metabolic production of ATP
oxygen-carrying capacity of blood is determined primarily by 2 variables- : the ability to adequately ventilate the ___ in the lungs and the ____ concentration of the blood
alveoli and hemoglobin(hb)
emphysema
degradation of the alveoli
