Fitness can be as simple as adding steps in your day!! (10,000)
• Collegeville, Minn. —
•5:00 - 5:45 a.m.: Wake up, shower, random stumbling around apartment. Steps: 140
•5:46 - 6:20 a.m.: Drive to work, park, and walk to office. Steps: 504
•6:21 a.m. - 12 noon: In office, including frequent pacing and trips to the studio and copy machine. Steps: 1,473
•12:01 - 12:30 p.m.: Walk downstairs three flights to lunch (healthy, of course), and back. Steps: 717
•12:31 - 3:00 p.m.: Back in office. Mostly at desk, writing important things. Steps: 336

•5:51 - 6:20 p.m.: Brisk 30-minute walk through St. Cloud neighborhood. Steps: 4,189
•6:21 - 9:00 p.m.: Cook dinner, typical lazy evening at home. Steps: 745
• Total steps: 11,140. It can be done. (2,000 - 2,200 steps = 1 mile)
ANAEROBIC (sprint/strength training)
• “Without oxygen”
• Uses specific muscle groups
• Can be maintained for a few seconds to about 90 seconds
• Body is working so hard it can’t supply the muscles with as much oxygen as they are using (called oxygen debt).
• Increases strength of heart, but does not have as many benefits as aerobic exercise
AEROBIC ACTIVITY (Cardiovascular – your conditioning level)
• “With oxygen” or “In the presence of oxygen”
• Uses large amounts of muscle groups
• Can be maintained continuously for a long period of time (15-20 minutes or longer)
• Rhythmic in nature
• Think of this as: Long in duration yet low in intensity
• Most beneficial in prolonging your life & quality of life. (most health benefits)
ANAEROBIC vs. AEROBIC
ANAEROBIC
Burning dry wood
Burns fast (can’t last)
High intensity (flames)
Lots of waste
(ashes/lactic acid)
AEROBIC
Burning wet wood
Burns slow (long time)
Low intensity (flames)
Little waste (ashes/lactic acid)
TYPE DESCRIPTION DURATION EXAMPLES BENEFIT
AEROBICNonstop, repetitive
Exercise20 Minutes or
moreSwimming, biking,
Running
Improves cardiovascular,
respiratory, & muscular endurance
ANAEROBIC
Intense, explosive – muscles use up more oxygen than the body
can supply
A few seconds to a few Minutes
Weight lifting, soccer, basketball, wrestling
Improves muscular strength, speed, &
agility. Also improves strength and size of
heart.
ISOMETRIC
Muscles contract, butthere is almost no
movement within the joint.
-Wall sits, squeezing a
tennis ball
Develops muscle strength at a specific
angle.
ISOTONIC
Muscles contract and relax through a full
range of motion (movement).
- Lifting weightsDevelops muscle
strength throughout range of motion.
ISOKINETIC
Muscles move through range of motion against a
changing resistance
-Special machines
(cybex)
Low risk of injury & develops muscle
strength throughout range of motion.
Exercise Recovery Ratio
Rest : Work• Aerobic (endurance activities)
1:1• Anaerobic (explosive & powerful)
2:1• Anaerobic Endurance (many team sports)
1½:1For example, if you were to sprint for 15 seconds, how long should you rest before
you do your next sprint??
FAST VS. SLOW
FAST TWITCH
• Produce force at a higher rate
• Intense/explosive
• Used when there is a limited time to generate a lot of force/speed
• Example: shot put
SLOW TWITCH• Can fuel repeated
and extended muscle contractions
• Fire slowly, but can go for a long time before fatigue
• Example: marathon
MUSCLE FIBERS• Humans contain a genetically determined
mixture of slow and fast twitch muscle fibers.
• On average we have around 50% fast and around 50% slow fibers (and about 2% intermediate)
• Training can alter intermediate fibers to imitate either the fast or slow fibers (depending on how you train).
WHO DOES WHAT?
Fast Twitch Intermediate Slow Twitch
A 80% 3% 17%
B 15% 4% 81%
C 48% 2% 50%
Lance Armstrong? Chester Taylor? Joe Johnston?

Terms• Hypertrophy:
Gain/Increase muscle mass• Atrophy:
Loss/Decrease muscle mass• Body Composition:
What percentage of your body is lean/muscle tissue, fat tissue, & water
• Progressive Overload Principle:To gradually increase the workload
BMR-Basal Metabolic Rate
Girls:A) Weight x 18 =B) (Weight x .9 x 24) / 2.2 = C) Weight x 10 = D)Take your answer to letter ‘C’ and add your original weight to that new number (1300 + 130 = 1430)
Average = (add up answers to A,B,C,D and divide by 4) =
Boys:A) Weight x 20 = B) Weight x 11 = C) (Weight x 24) / 2.2 = D) Take your weight and put a
“0” at the end of it (ex. 130 = 1300)
Double your original weight (130 + 130 = 260) and add that new number to the previous one. (1300 + 260 = 1560)Average = (add up answers to A,B,C,D and divide by 4) =
Minimum amount of calories you need to sustain life
Resting Heart Rate (RHR)
• Best taken after a long rest (morning)
• Average: 60-80• The lower, the better – it’s common for an
endurance athlete to have a RHR of 40 bpm’s• Calculation: Take pulse for 60 seconds, this is
your heart rate.
Maximum Heart Rate (MHR)
• 220-Age
• Don’t want to go above this number.
• Consequences of going over may be fainting or if your older, a heart attack. A heart attack can also occur in someone younger if a heart defect is present, many times of which you are unaware of.
Target Heart Rate (THR)
• The heart rate you want while you are exercising.
• If you go below this, you aren’t working hard enough for it to have a sizable impact. If you are above this range, you are working too hard and the workout is no longer benefiting your cardiorespiratory system.
• 220-Age or MHR. Take that # and multiply it by .60 and by .80. This will give you the lower and upper limits…the range you want to be in.
Recovery Rate
Sometimes the best measure of your level of conditioning is how quickly your heart rate returns to normal after prolonged exercise. The quicker it recovers, the better shape you are in.
Warm-upPurpose: •To increase muscle and total body temperature•To prepare the body for increased stress•To reduce the risk of injury•To mentally prepare the body for competition
Steps to a Warm-up:
•A light exercise using large muscle groups, such as a short jog•Stretching, making sure to stretch all large muscle groups•Sport specific drills, such as lay-ups and free-throws•Activity of your choice in which your THR is reached / sustained
