What is Fitness? Flashcards
What is fitness?
Fitness is work capacity across broad time and modal domains.
What are the four pillars that CrossFit uses to evaluate fitness?
- The 10 general physical skills
- The hopper
- The metabolic pathways
- Sickness-Wellness-Fitness continuum
What is the CrossFit theoretical hierarchy (pyramid) of the development?
- Nutrition
- Metabolic conditioning
- Gymnastics
- Weightlifting and throwing
- Sport
What are the 10 general physical skills?
Organic (develop by training)
- Cardiorespiratory endurance
- Stamina
- Strength
- Flexibility
Neurological (develop by practice)
- Coordination
- Accuracy
- Agility
- Balance
Both
- Power
- Speed
What is the hopper model?
It is a balance of skills and drills to be ready for anything that could come.
The fittest person will perform statistically best across all the activities, and a fitness program should better prepare an individual for any conceivable event.
What are the three metabolic pathways?
The fittest person will have the best balance of capacity across all pathways, and a fitness program should develop your capacity in each.
- Phosphagen
- Glycolytic
- Oxidative
What are the characteristics (% max power, and duration) of the glycolytic pathway?
- Also called the lactate pathway
- Can produce approximately 70% of maximum power
- Lasts about 2 minutes, peaking at approximately 60 seconds — e.g., 400-meter sprint
What are the characteristics (% max power, and duration) of the phosphagen pathway?
What are the characteristics (% max power, and duration) of the oxidative pathway?
- Also called the aerobic pathway
- Can produce approximately 40% of maximum power
- Sustainable until the anaerobic threshold is crossed — e.g., a 10,000-meter run
To develop the best overall capacity in all three energy systems, a training program should rely primarily on which pathway?
The glycolytic pathway, using shorter, higher-intensity work.
What is the Sickness-Wellness-Fitness continuum?
The fittest will have “fit” values for any measurable marker, and a fitness program should push every marker in that direction.
Fitness is and should be “super-wellness.”
Fitness act against sickness
What the characteristics of sickness?
Body fat percentage
Blood pressure
Resting heart rate
- Body fat percentage: 30%
- Blood pressure: 200/115
- Resting heart rate: 100 beats per minute
What the characteristics of wellness?
Body fat percentage
Blood pressure
Resting heart rate
- Body fat percentage: 20%
- Blood pressure: 120/70
- Resting heart rate: 70 beats per minute
What the characteristics of fitness?
Body fat percentage
Blood pressure
Resting heart rate
- Body fat percentage: 10%
- Blood pressure: 110/60
- Resting heart rate: 50 beats per minute
How do we measure fitness?
Work capacity across broad time and modal domain
The work capacity is the area under the curve: power (work capacity) in the function of the workout duration. This curve is the best fit for an athlete’s workouts. The bigger the area is, the bigger the work capacity is.
