Study Notes
Exercise Physiology & Health
- Exercise physiology involves understanding the body's responses to exercise.
- Physical activity refers to any muscle movement requiring energy.
- Fitness is the ability to perform routine physical tasks without fatigue.
- Performance describes how well a physical task can be completed.
- Health represents the overall state of both body and mind.
- Cardiopulmonary resuscitation (CPR) involves lung compressions, typically 100 per minute.
- Infant CPR requires two-finger compressions, 1.5 inches deep, with mouth-to-mouth resuscitation covering the baby's mouth and nose.
- The Heimlich Maneuver consists of 5 back blows using the heel of the hand, followed by 5 thrusts.
- Atherosclerosis is the buildup of plaque within the arterial walls of the heart.
- In an emergency situation, the three C's are: check, call, and care.
- There are roughly 4 million concussions per year.
- BMI levels: Below 18.5 is underweight, 18.5 to 24.9 is normal, 25 to 29.9 is overweight, and 30 and up is obese.
- Cardiorespiratory endurance is the heart and lungs' capacity to supply oxygen during exercise.
- Muscular strength is the maximum force a muscle can exert.
- Muscular endurance is the muscles' capacity to sustain repeated contractions.
- Flexibility is the range of motion around a joint.
- Body composition is the ratio of fat to lean mass in the body.
- Anaerobic exercise is high-intensity exercise that doesn't require oxygen, such as sprinting.
- Aerobic exercise is low to moderate-intensity exercise that requires oxygen, such as jogging.
- VO2 Max is the maximum amount of oxygen the body can use during exercise.
- Lactic acid is a byproduct of anaerobic metabolism that can cause muscle fatigue.
- The overload principle states that to improve fitness, the body must be exposed to stress beyond normal levels over time.
- The specificity principle states that training should be relevant to the desired activity or goal.
- The progression principle emphasizes the need to gradually increase exercise intensity over time.
- The FITT principle stands for Frequency, Intensity, Time, and Type of exercise.
- Hypertrophy is an increase in muscle size due to exercise.
- Atrophy is a decrease in muscle size due to inactivity.
- EPOC (Excess Post-Exercise Oxygen Consumption) is the body’s need for oxygen after exercise, to restore homeostasis.
- Basal Metabolic Rate (BMR) is the number of calories the body needs at rest to maintain basic functions.
- Isometric contraction is muscle contraction without movement, like in a plank.
- Isotonic contraction is muscle contraction with movement, like in a bicep curl.
- Concentric contraction is when a muscle shortens while contracting, like lifting a weight.
- Eccentric contraction is when a muscle lengthens while contracting, like lowering a weight.
- ATP (Adenosine Triphosphate) is the primary energy source for muscle contractions.
- Fast-twitch muscle fibers generate power quickly but fatigue fast, such as during sprinting.
- Slow-twitch muscle fibers contract slowly and resist fatigue, such as during endurance running.
- An agonist (prime mover) is the muscle that contracts and directly causes movement; the bicep during a bicep curl is an example.
- An antagonist is the muscle that opposes the agonist; the tricep is the antagonist during a bicep curl.
