What is physical fitness
A SET OF PHYSICAL ATTributes that allows the body to respond or adapt to the demands and stress of physical effort.
5 health related components of physical fitness and defenitions.
Muscular strength(1 rep max). Muscular endurance(rep max). Body composition(% of fat bone muscle in body). Cardio respiratory endurance( ability to perform large muscle whole body exercise for extended periods). Flexibility
What is exercise.
A subset of physical activity that is volitional, planned, structured, repetitive, and aimed at improvement or maintenance of physical fitness or health.
Physical benefits of exercise
Reduces risk of heart disease, high blood pressure, diabetes, and some types of cancer. Metabolism more efficient. Improves body composition and weight management. Increases bone mass and decreases osteoporosis risk. Moderate exercise may increase immune function. Inc muscle tone strength. Helps slow some changes assoc w aging process. Results in longer life span
Psychosocial benefits of exercise
Reduces fatigue, stress, and boosts mood. Decreases anxiety and depression. Feeling of self control, self esteem, and self confidence. Improves and maintains cognitive function. Social interaction and inc participation in active pursuits.
FITT
Frenquency. Intensity. Time. Type
ACSM rec
Mod intese cardio 30 min day 5 day week
Vigorous radio 20 min day 3 day week
At least 2 strength training a week at least one set 8-10 exercises for main muscle groups
2-3 flexibility workouts for major muscles.
VO2 max
Maximal rate of 02 uptake during aerobic. exercise
Anaerobic exercise
Short bursts high intensity exercises
Aerobic exercise
Activities that involve continuous rhythmic movements of large muscle groups
Benefits of cardiovascular training
Reduced risk of cv disease, diabetes. Decre resting heart rate. Dec blood pressure. Hearts mass and volume inc. inc vo2 max and oxygen extraction. Inc metabolism and body composition.
Measuring cardio intensity.
Target heart rate zone 60-80% of age predicted max hr(220-Alex.60)
Rep estimate how hard workout feels
Talk test you should be breathing g hard but still able to carry conversation.
How to determine Age predicted max heart rate
220- age x .60
Warm up w 5-10 mins of low intes aerobic importance
Raises temp of working muscles, spreads synovial fluid in joints and prepares cv system.
Stretch after warm up or after workout
Cool down w 5-10 mins of low intensity aerobic importance
Brings body back to normal. Finish workout with stretching
Muscular strength
The max amount of force a muscle can produce with a single effort
Muscular endurance
The ability to perform muscular effort repeatedly over time
Hypertrophy
Increase in volume of organ or tissue due to enlargement of component cells
Atrophy
Decrease in size of a body part cell organ or other tissue
Strength gains due to neural adaptation and hypertrophy
Early strength gains within first 2 months of training
Type 1 muscle fibers
Slow twitch less power more endurance
Type 2 muscle fibers
Fast twitch more power less endurance
