-muscular strength and endurance -flexibility |
|
sub-components of fitness
|
-power
-agility -body composition |
|
what happens when you are physically fit
|
-you can do all the things during the day and still have energy left over
|
|
why cardiovascular endurance important?
|
-isolating muscle important to keeping us alive
-efficient in getting fit in broad spectrum |
|
two kinds of cardiovascular exercise
|
-aerobic
-anerobic |
|
aerobic exercise
|
-with oxygen
-low to medium intensity -long duration -burns body fat |
|
anaerobic exercise
|
-high intensity
-short duration -not effective incurs oxygen debt -burns calories from carbohydrates not fat |
|
what is the best indicator of what kind of exercise one is performing?
|
-breathing
|
|
how fat burn
|
-fat metabolize and burn up with the constant presence of oxygen
|
|
what is target heart rate zone?
|
-zone of exercising aerobically
-based on resting heart rate and age -uses Karvonen formula |
|
Karvonen formula
|
220-28 (age) = 192 (max hr
- 72 RHR ---------------- 120 *60 ______________ 144-168 |
|
Benefits of regular aerobic activity
|
-lose fat
-more energy -sleeping better -metabolism is increasing (greatest benefit to exercise) -mental acuity -reduce resting heart rate |
|
what is metabolism
|
-rate at which burn calories
|
|
what increases metabolism other than exercise
|
-genetics
-eating 6 to 7 meals per day -caffeine |
|
what are the benefits of reduced resting heart rate?
|
-reduced risk of CVD
-bone mass increase can be gained until 35 years old |
|
muscular strength
|
-recruiting fibers; get muscles get used to work
|
|
how to gain muscular strength
|
-high weight 8-10 reps 2-3 sets
|
|
hypertrophy
|
-gain in muscle mass
|
|
atrophy
|
-loss in muscle mass
|
|
muscular endurance
|
-getting fibers to "fire" longer
-lower weights 15-30 reps 2-3 sets |
|
what does flexibility do?
|
-reduce risk of injury
|
