9/16/2024 Develop a basic understanding of the adaptations that occur due to physical activity Begin to draw the connection between these adaptations and health outcomes 1 Physical Activity SKELETAL MUSCLE 2 3 1 9/16/2024 Physical activity of adequate volume imposes a stress that causes almost all physiological systems to respond. In response to frequent physical stress, Both physical, Neural and biochemical adaptations occur in an effort to make physical activity more efficient These ACUTE and CHRONIC adaptations IMPROVE the species ability to perform physical work “It just so happens” that these performance related adaptations also result in improved health! Removal of the physical stress results in reversal of these adaptations (deconditioning) 4 5 6 2 9/16/2024 ENERGY 7 ATP (Adenosine Tri-Phosphate) is the immediate energy source used for muscle contraction.

The main proteins that interact to facilitate muscle contraction are? The primary source of fuel for muscle contraction is? This source of fuel results from the breakdown of ? 10 11 CHRONIC INCREASED MYOGLOBIN INCREASED MITOCHONDRIA INCREASED CAPILLARY DENSITY INCREASED STORES OF GLYCOGEN INCREASED OXIDATIVE USE OF GLYCOGEN INCREASED STORES OF TRIGLYCERIDES INCREASED OXIDATION OF FATS 12 4 9/16/2024 Muscle Fiber Types 13 Exercise Intensity Aerobic Aerobic (Requires Anaerobic (No (requires O2) O2) O2) Oxidation of Fat Oxidation of Extreme LA Glucose produced Lactic Acid Glycolysis production ATP-PC 14 15 5 9/16/2024 16 Study Guide Questions Why does the human species adapt to physical activity? What is the primary source of fuel of muscle contraction? What is it developed from? Describe the different muscle fiber types. How do the functionally differ? 17 6
