Exercise Physiology Optimal Physical Fitness Optimum fitness is the development of an optimum level of cardiovascular endurance, muscle strength, flexibility, diet, and an ideal body weight. Fitness Testing Fitness testing are often performed in a controlled laboratory or in field testing. Controlled Laboratory Environment - When fitness tests are done in a controlled laboratory environment, precision instruments are often used like gas analyzers to measure true oxygen consumption, hydrostatic tanks with helium or nitrogen washout apparatus to measure body composition, isokinetic machines to measure strength. Field tests give the personal trainer opportunities to test without using expensive equipment. Field Testing - In field testing, personal trainers use prediction equations. Some field test examples are the skin fold caliper, tape circumference measuring, the 1.5 mile walk / run used for testing aerobic capacity. Physiology Of The Cardiopulmonary / Cardiorespiratory / Cardiovascular System Energy Systems – Energy Production In The Cells Cardiopulmonary / Cardiovascular System Response To Exercise Changes In Oxygen Delivery Changes In Cardiac Output Changes In Oxygen Extraction Guidelines For Cardiovascular Fitness Type Of Exercise Intensity Of Exercise Duration Of Exercise Frequency Of Exercise Warm Up And Cool Down Benefits Of Regular Aerobic Exercise Environmental Concerns
Basic Skeletal Muscle Anatomy And Physiology Adaptations To Strength Training Muscle Fiber Adaptation - The muscles hypertrophy, increasing in number of size of myofibrils inside muscle fibers, therefore stronger. Connective Tissue Adaptation - Change in connective tissue, the cartilage, ligaments, tendons which become stronger in response to exercise Increased Nervous System Activity - Increased stimulation of motor units that were previously unstimulated and inactive, therefore helping to increases muscular strength. Decreased Nervous Inhibition - Psychological confidence increases and physiological adaptation increases with the Golgi tendon organ adapting to allow the muscle for maximum contraction, therefore more muscle power and strength. Strength Training Guidelines Strength Type Overloads Isometric Contraction - Isometric literally means same length, when a muscle is contracted without movement, usually against a wall, etc. Isotonic Contraction - Isotonic means same tone or same tension, which refers to exercises with a certain amount of external resistance through entire range of motion. The muscle tension is not constant, for example, dumbbell curls have the same weight or a constant force. Dynamic constant external resistance refers to strength exercises with a fixed amount of external resistance. Dynamic variable external resistance refers to cam based machines Isokinetic Contraction - Isokinetic means same speed, type of resistance exercise with constant speed or velocity. Muscle Fatigue - Muscle fatigue is a function of exercise intensity and duration. The more intense the exercise, the muscles fatigue quicker. The longer a muscle is exercised, fatigue sets in. other fatigue factors include dehydration, increased body temperature, by products other than lactic acid, boredom with activities. Muscle Soreness - There are two types of muscle soreness which are immediately after the exercise performed and the delayed onset of muscle soreness. Flexibility Training Flexibility, the range of motion about a joint, is increased when the range of motion around a specific joint increases. Flexibility is limited by four factors: the ligaments and tendons elastic limits, the muscle elasticity, the bone and joint structure, and the skin. Muscle spindles protect the muscles from being stretched too far, just as Golgi tendon organs protect against too much contraction or contractile force.
