• Financial resources • only so much money, misdirected funds, what is your

• Mental resources • cognitive load and devotion of mind to tasks/goals
• Time resources • Just in time life, scheduling efficacy, lap time analysis
• Resource Hierarchy, Resource Shortfall

Morbid Obesity
• 1993 to 2006
– 1.8 to 6.1 per thousand participants was found (increase >200%).
– Morbid obesity prevalence higher in women.
• 4% increase in prevalence per year in women
• 12% per year in men

What do we need to see?
• Mandatory: A change in the right direction for each group over semester.
• Nice: A difference between groups after semester.
• Ideal: A long term change – 3 years.
– physical activity
• climate dependent,
• stimulus to drive CVF and body composition changes
– cardiovascular fitness – most important as related to disease
– body composition – why we are doing it in the
