Factors influencing movement and performance Flashcards
(14 cards)
ATP-PCr System
Energy source: phophocreatine
Duration of peak energy production: 5-10 seconds
Percentage contribution at rest: less than 5%
Percantage contribution at max intensity: 55%
Recovery time until repeat effort: phosphocreatine replenishment: 3-5 min with 50% in 1st 30 seconds
Intensity + duration of activity where the system is dominant ATP provider: maximal intensity (>95% and duration of 1-10 secounds)
Example: elite 100-m sprint
Glycolytic
Energy source for ATP production: carbohydrate (glycogen)
Duration of peak energy production: 60-90 seconds
Percentage contribution at rest: 15%
Percentage contribution at max intensity: 40%
Recovery: 15 min to 2 hours
Cause of fatigue: accumulation of lactic acid
Waste products: lactic acid, hydrogen ions
Intensity: high (85-95%)
Example: 200m run
Aerobic
Energy source: carb, fat, protein
Duration: as it’s low intensity (no limit)
Waste products: water + c02
Recovery time: Time to replace fuel stores (up to 48hrs
Cause of fatigue: Loss of muscle and liver glycogen and fat store
Contribution at rest: 80%
contribution at max intensity: 5%
How to calculate max HR
max HR = 220-age
Training methods
- Continuous
- Anaerobic interval
- HIIT – high intensity interval training
- SIT – sprint interval training
- Fartlek
FIIT PRINCIPLE
Frequency: How often, how many times per day or week.
Intensity: How hard are you training, how hard are you working between 0-100% max effort, R.P.E or Heart rate (V02 max)
Type: What kind of training, many types 4 main: aerobic, anaerobic, strength and flexibility within these training types there are many different training methods.
Time: How long are you training, seconds (in a rep), minutes hours
Immediate physiological responses to training: heart rate
Meanings: Beats per minute
Measured: pulse, HR monitor, or ECG
IR2E: Increases sharply, then stabilizes (fit) or keeps rising (unfit)
Cause of change: Increased intensity, oxygen demand, fitness level, nervous system
Ventilation rate
Meaning: Ventilation Rate: Breaths per minute; measures air movement in and out of lungs
IR2E: increases
Cause of change: Higher intensity increases oxygen demand
Stroke volume
Meaning: Blood pumped per beat (mL/beat)
IR2E: Increases until it plateaus
Causes: More intensity = greater need for oxygenated blood
Cardiac output (CO)
Meaning: HR × SV = blood pumped per minute
IR2E: increases
Causes: More intensity = more oxygen needed by muscles
Lactate levels
Meaning: Acidic byproduct of anaerobic exercise; measured in blood
IR2E: Acidic byproduct of anaerobic exercise; measured in blood
Causes: Intensity rises = lactate builds faster than it can be removed
