Week 2
The Assignment:
-Exercise heart rate, times by 6
-walking time 6.9
Scientific method: observation, ask question, form hypothesis, conduct experiment, accept or
reject.
Reject: form hypotheses, conduct experiment - accept or reject - repeat
Conjecture, hypothesis, theory, law
Six Rules of Evidential Reasoning
“We are taught what to think, not how to think!”
1.Falsifiability
-undeclared claim
-multiple outs
2. Logic
3.Comprehensiveness (all evidence) - checking all the possibilities and being honest about it
4. Reproducible
5. Sufficiency
6. Honesty
Overload Principle: You have to stress your systems for improvement
Specificity Principles: It’s specific. If you want to be good at running, run. Swimming, swim
Individual Differences Principle: Do what’s good for YOU
Principle of Reversibility: Use it or lose it
The “FITT”ness Formula
Frequency: how many days/week - 3, 3-4, 5+
Intensity:% of Max HR - 50-80%, 60-85%, 70-90%
Time: Duration: 20, 20-45, 30-60
Type: Any rhythmic activity that uses large muscle groups: walking, cycling, stair machine,
jogging, swimming, etc
Assessing Exercise Intensity
-Percentage of Maximal Heart Rate
-Heart Rate Reserve: 50-85% of heart rate reserve (resting heart rate
-198-60=138
-Perceived Exertion
-Talk-Test Method: If you can speak while running, you’re okay. If you can’t, you’re too intense
for long distance. Be a little breathless, but have a conversation
-Intensity Training Zones (critical power)
