Abstract: | Force-velocity data at different temperatures (range, 10-35 degrees C) from intact fibre bundles are analysed to determine the temperature dependence of the maximal mechanical power output of fast and slow rat muscles. At 35 degrees C, the maximal mechanical power was approximately 250 kW m(-3) (=250 microW mm(-3)) in fast (probably an underestimate) and approximately 100 kW m(-3) in slow muscle. Within the more physiological temperature range (25-35 degrees C), the temperature coefficient (Q10) of maximum power was 2-2.5. In both muscles, the maximal power at 10 degrees C was only about 3-5% of that at 35 degrees C, the decrease being particularly pronounced at temperatures below 20 degrees C (Q10 of 5-7). |
