Document Summary
In greco-roman cant to anything below the waist. 2 3 min rounds- 6 minutes of total work- huge aerobic component to wrestling. 2-3 hours is moderate duration (relative to marathons) Longer the duration of particular performance, the longer the output fatigue: Up to 60 sec max. effort of exercise. Black line: force direction over 60 sec. First few seconds is atp, then pcr conc. available, maintain atp, around 15 seconds, start to utilize anaerobic glycolysis, power output decreases, once you"re at 45-60 seconds, using aerobic system. Tremendous drop in power out put in the first few seconds to 60 seconds. Maintaining atp availability to muscle by breaking down pcr to replace energy concentration, but depleting pcr almost completely by 30 seconds. See linear increase in lactate and h+ over 60 seconds. Lactate and h+ are directly related to glycolytic energy system. When looking at someones peak lactate, it represents the energy they"re getting from anaerobic glycolysis.
