300

What does Respiratory exchange ratio measure?

Measures the ratio of carbon dioxide produced compared to oxygen consumed during exercise.

300

Name 2 ways the fast replenishment stage uses oxygen during recovery.

  1. Re-saturation of myoglobin with oxygen 

  2. Resynthesis of Phosphocreatine

List 5 ways Physiology affects Vo2 max

 Increased maximum cardiac output

• Increased stroke volume/ejection fraction/cardiac hypertrophy

• Greater heart rate range

• Less oxygen being used for heart muscle so more available to muscles

• Increased levels of haemoglobin and red blood cell count

• Increased myoglobin content

• Increased capillarisation around the muscles

• Increased number and size of mitochondria

• Increased surface area of alveoli

• Increased lactate tolerance

400

In the aerobic system, where inside the muscle cell do the Krebs cycle and the Electron Transport Chain take place?

Mitochondria

400

What do results of the Vo2 max testing tell the athlete's coach?

  • Helps identify an athlete’s aerobic fitness level

  • Used to set training intensities and endurance training zones

  • Allows comparison with other athletes or previous tests

400

When does OBLA occur?

4 mmol per litre

400

Name the 3 phases of plyometric training 

1. Eccentric phase

2. Amortisation phase

3. Concentric phase

500

What is the average Vo2 max for teenage males and females

Males - 45-55 ml/kg/min

Female - 35-44 ml/kg/min

500

Draw out the Whole diagram of the Anaerobic System

Whatever Ms Burke says

500

What does the results of an RER closer to 0.7 indicate and closer to 1.0 indicate?

0.7 indicates the body is mainly using fat for energy

1.0 indicates the body is mainly using carbohydrates for energy

500
