Document Summary
Too much not enough rest never recover enough performance trend/ capacity decreases. Dynamic warm-up: high kicks, etc, better than static stretching. Decreased resistance in vascular bed, allow haemoglobin & myoglobin to dissociate more o2 at working tissue: increased psychological preparedness. Sufficient intensity and duration to increase muscle temp and allow re-synthesis of high energy phosphates. 5-10 minutes in duration at 40-60% vo2max: 80-90% vo2max decreases performance, can increase performance with a proper warm-up. Intermediate (10s 5 min) and long-term (>5mins) performance. Need to elevate vo2 but not cause fatigue. Cant be too intense 60-70% vo2 max. Need short rest period prior to competition. Talk test= below vo2 max if they can talk, if they cant talk they are well beyond vo2max. Easy as 1,2: analyze the physiological/ physical challenges of the sport, design exercises to prepare each system for those demands.
