Study Notes
Physical Activity and Aerobic Exercise
- Physical activity is bodily movement from muscles and bones requiring energy. It includes chores, work, and recreation.
- Aerobic activity involves the heart and lungs working together to deliver oxygen and nutrients for exercise.
- Aerobic activities include walking, jogging, jumping rope, swimming, and cycling.
- Exercise is a subcategory of physical activity.
- Aerobic exercise, also known as cardiovascular exercise, is a rhythmic activity using large muscle groups for cardiovascular conditioning.
- During exercise, the lungs and heart provide oxygen to working muscles.
- Overexertion occurs when a person exerts too much pressure on themselves, possibly leading to discomfort or more serious damage.
- Exerting yourself too hard, too fast, or too rapidly can transition from the aerobic energy system to the anaerobic energy system if the muscles need more oxygen than available.
- Anaerobic refers to a state where no oxygen is available.
- Three main types of physical activity are aerobic, muscle strengthening, and bone strengthening.
Muscle and Bone Strengthening
- Muscle strengthening involves working or holding muscles against some force or weight.
- Muscle strengthening develops muscles to be stronger as they perform more labor.
- Muscular contraction occurs during muscle strengthening exercises.
- Muscle fibers rebuild and repair themselves during rest periods following an exercise.
- Muscle hypertrophy is the term for muscle growth after stimulation and healing.
- Muscular strength is the maximum force one muscle can generate. Measured by lifting heavier weights for fewer repetitions.
- Muscular endurance is the ability of a muscle to sustain repeated contractions against resistance for an extended period. Exercised by performing repetitions with moderate weights.
- Muscle strengthening improves general health and athletic performance.
- Muscle strength contributes to maintaining a healthy weight by burning calories.
- Muscle strength improves stability, balance, and flexibility, reducing injury risk.
- Stronger bones are a result of strength training.
Sports Injuries
- Sprains involve torn ligament fibers, muscles, or tendons.
- Bruises occur when small blood vessels break, releasing blood into the surrounding soft tissues.
- A concussion happens from a direct hit to the head.
- Dislocations occur when the ball of a joint is driven out of its socket.
- Fractures occur when bones break, crack, or shatter.
- Strains are tendon injuries involving stretching, partial ripping, or complete ripping of a tendon.
- Swelling and pain after an injury to an ankle, knee, or joint are common.
RICE Method
- Rest, Ice, Compression, and Elevation (RICE) is a therapeutic procedure to reduce swelling, relieve pain, and enhance healing and flexibility.
Other Causes of Injuries
- Dehydration occurs when the body loses more fluids than are replenished. Symptoms include a dry mouth, less urine (and dark colored urine), and fainting.
- Prevention by drinking enough water, eating watery fruits and vegetables, and avoiding hot areas is better than recovering from dehydration.
- Hypothermia is a condition in which the body's temperature drops rapidly.
- Hyperthermia is a condition in which the body temperature increases significantly above 37 degrees Celsius.
Types of Exercise
- Resistance training involves exercises using resistance, like weights or body weight, to work muscles. This increases muscle mass.
- Circuit training involves alternating between multiple workouts targeting various muscle groups.
- Flexibility exercises help stretch muscles and increase joint range of motion.
- Static stretching involves holding a stretch for 10 to 30 seconds, carefully relaxing into the stretch, and gradually releasing the stretch. It's effective after a warm-up or at the end of a session with muscles warmed up. Types of static stretching include active, passive, and dynamic.
