VO2 Max Test: Run on treadmill at predetermined set speed with increase in gradient 1% every minute until exhaustion. No lactate samples measured. Data you will leave with: maximum oxygen uptake, maximum heart rate, heart rate at 'lactate threshold' based on non-blood parameters.
Submax Test or Lactate Threshold Test: Run on treadmill at progressively higher speeds every three minutes with finger prick sample of blood for lactate measurement. Must be able to hop off and straddle moving treadmill and hop back with each stage. Test does not have to go to exhaustion. Speed and Heart Rate at lactate levels of 2 and 4 mmol are determined with pattern of heart rate and lactate as speed increases.
