Muscle power
- An exercise-induced improvement in isolated skeletal muscle contractility does not affect the performance-enhancing benefit of 70 µmol l−1 caffeine treatment
Summary: The performance-enhancing effect of caffeine is not improved following exercise training as shown by assessing the effects of 70 µmol l−1 caffeine on muscle isolated from trained and untrained mice.
- Simulated work loops predict maximal human cycling power
Summary: Simulated maximized work loops closely predict experimental joint power during maximal voluntary cycling, demonstrating that, like birds and fish, humans are capable of maximizing muscle power.
- Bluegill sunfish use high power outputs from axial muscles to generate powerful suction-feeding strikes
Summary: Although the sternohyoideus muscle shortens to generate small amounts of power, bluegill sunfish require large regions of axial musculature – operating at or near maximum power output – to power suction feeding.
- Swim and fly: escape strategy in neustonic and planktonic copepods
Summary: New analysis supported by high-speed videos explains how some copepods can perform out-of-water escape jumps when aided by well-timed kicks when penetrating the surface.
