Study Notes
Exercise Physiology & Health
- Exercise physiology examines how the body responds to exercise.
- Physical activity involves any muscle movement that requires energy.
- Fitness is the ability to perform routine physical tasks without fatigue.
- Performance measures how well a physical task is completed.
- Health encompasses the overall state of the body and mind.
CPR and Emergency Procedures
- CPR (Cardiopulmonary resuscitation) involves lung resuscitation, requiring 100 compressions per minute.
- CPR for infants requires using two fingers to compress 1.5 inches deep, with mouth-to-mouth breaths covering the baby's mouth and nose.
- The Heimlich Maneuver involves 5 back blows with the heel of the hand, followed by 5 thrusts.
- Atherosclerosis is the buildup of plaque within the arterial walls of the heart.
- Emergency situations require checking the scene, calling for help, and providing care.
- Concussions occur about 4 million times per year.
Body Mass Index (BMI)
- BMI levels below 18.5 indicate underweight.
- BMI between 18.5 and 24.9 is considered normal.
- BMI from 25 to 29.9 indicates overweight.
- BMI of 30 percent and higher indicates obesity.
Cardiorespiratory and Muscular Fitness
- Cardiorespiratory Endurance is the heart and lungs' ability to supply oxygen during exercise.
- Muscular Strength represents the maximum force a muscle can exert.
- Muscular Endurance is the ability of muscles 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.
Types of Exercise
- Anaerobic Exercise is high-intensity and doesn't require oxygen, like sprinting.
- Aerobic Exercise has a low to moderate intensity and requires oxygen, like jogging.
- VO2 Max is the maximum amount of oxygen the body can use during exercise.
- Lactic Acid results as byproduct of anaerobic metabolism causing muscle fatigue.
Principles of Training
- Overload Principle states that to improve fitness, the body must be exposed to stress beyond normal levels over time.
- Specificity Principle dictates that training should be relevant to the desired activity or goal.
- Progression Principle emphasizes the need to gradually increase exercise intensity over time.
- FITT Principle includes 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) signifies 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.
Muscle Contractions
- Isometric Contraction is a muscle contraction without movement, like a plank.
- Isotonic Contraction is a muscle contraction with movement, like a bicep curl.
- Concentric Contraction occurs when a muscle shortens while contracting, like lifting a weight.
- Eccentric Contraction happens 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, like in sprinting.
- Slow-Twitch Muscle Fibers contract slowly and resist fatigue, as in endurance running.
