Exam 1 Flashcards
Who are the 3 who won the Nobel Prize for work related to muscle and exercise?
A.V Hill
Otto Meyerhof
August Krogh
What was the relevance of Harvard Fatigue Laboratory (1927-1947)?
D.B. Dill was the director for exercise, clinical and environmental physiology
No other lab has had more of an impact on the field of exercise physiology
Who coined the term maximal oxygen uptake?
Elsworth Buskirk (increasing resistance until body can no longer exercise)
What were active research areas in HFL?
metabolism, environmental and clinical physiology, aging, blood and physical fitness
What is body temperature at rest?
normal (98.6 F, 37 C)
fever (104 F, 40 C)
How does body maintain body temperature at rest?
Claude Bernard (>100 yrs ago) discovered that the internal environment of the body remains remarkably constant despite external enviornment
What is homeostasis?
(normal)
maintenance of a constant or unchanging internal environment
normal resting/unstressed conditions
What is a steady state?
(unchanging)
steady physiological environment
balance between demands placed on body and the physiological response to those demands
*doesn’t necessarily mean that the environment is normal, like your core temp steadying when you exercise and temp inc to new ‘normal’
What is the goal for the control systems of the body?
to regulate some physiological variable at or near constant value
Ex. pulmonary and circulatory systems of the lung and heart
What are the biological control systems?
series of interconnected components that serve to maintain a physical or chemical paramter at or near constant
