Document Summary
Comparative effectiveness of exercise and drug interventions on mortality outcomes. Monitoring high intensity endurance exercise with hr and thresholds. Vo2max as a predictor of endurance exercise: thresholds are critical as well, the higher the vo2max, the higher threshold and therefore can use o2 maximally as a predictor of performance. There is a specific sub max level of work above which prolonged work is decreased. Ventilatory (vt) and anaerobic/lactate (at) thresholds (4mmol) Since prolonged exercise is aerobic, at is best lab method to evaluate endurance capacity. Rise in blood la reflects the inclusion of energy from anaerobic glycolysis (h+ effects causing fatigue) Thresholds have been used to determine training intensities. Perception of effort (rpe: opportunity to gage individual intensity of wr, disadvantage: everyone will have a different idea of what hard is. Hr, easy access to hr monitors (many cardio machines) Co2 production- increase in wr, increase co2 above threshold, increases ventilation at threshold- non- linear increase.
