Document Summary
Energy producion (see h&f chap 4 on bcourses) o. Improved cellular metabolism: ^ capillary/iber raio, larger/more mitochondria, spared cho, beter use of fat and lactate: three energy systems immediate, non-oxidaive, oxidaive, fuel uilizaion based on ex intensity (fig 4. 7) and duraion (fig 4. 8) Slow-twitch vs fast-twich: in normal humans, about 50/50 raio. 1: improved pulmonary venilaion; fr(breaths/min) x vt (l/min) = ve (l/min) fr = breaths/min (average: 12) Vt = tidal volume: how many liters of air per breath. Ve: minute venilaion: how many liters per minute. Venilatory threshold: air intake suddenly increases exponenially during exercise. This indicates lactate threshold (switch to nonoxidaive) (fig 4. 13: lactate threshold vs obla (fig 4. 12, improved cardio-respiratory funcioning. Endurance training has no efect on max heart rate!!: max hr ~ 220 age o. Key concept: at the same exerion, trained will have a lower hr as untrained. Untrained vs. trained: untrained has higher hr, lower sv o.
