KIN 352 EXAM 1 (100% Correct)

Who were the main personalities involved with the Harvard Fatigue Laboratory (HFL) laboratory and its development? correct answers D.B. Bill, L.J Henderson, Sid Robinson, Steven Horvath, and Peter Karpovich Erik Howhu Christensen correct answers Studied under August Krogh, studied athletes and nutritional impact on performance collaborating with Erling Asussen and Marius Nielsen to make the Three musketeers. August Krogh correct answers Father of exercise physiology and worked in Bohr's lab during the late 1890s. Won the nobel peace prize in 1920 for capillary diffusion. Studied Diet and oxygen deficit and built intrumentation for physiological measurement. What is ACSM? correct answers American College of Sport Medicine founded in 1954. They discovered the muscle contraction sliding filament theory and discover people can run sub 4 min miles by Roger Bannister. Potential energy correct answers energy of position, in biological systems that are stored within chemical bonds Kinetic energy correct answers energy of motion, heat or movement ATP correct answers Our body's currency that is made up of adenine, ribose, and 3 phosphate groups 1st law of energy transfer correct answers Energy is neither created or destroyed, the body just transform it from one form into another 2nd law of thermodynamics correct answers the potential of energy in any spontaneous process always proceeds in a direction that decreases the capacity to do work How do the laws of energy transfer relate to exercise correct answers because the food we eat is metabolized into ATP for our muscles to use to contraction via skeletal muscle proteins and the rest of it the work done is lost as heat. 2 major types of chemical reactions correct answers Exergonic and endergonic Example of exergonic correct answers catabolic reactions release energy in glucose, glycerol, fatty and amino acid breakdown Example of endergonic correct answers anabolic reactions require energy for glycogen, triglyceride, and protein synthesis. efficiency of energy transfer correct answers 15-30% range of human efficiency the rest is lost as heat which is around 70-85%
