Absolute values of and changes in muscle adenosine triphosphate (ATP), creatine phosphate (CP) and lactate (in mmol (kg dry weight)−1), water content (%) and pH before and after 20 and 90 s of low intensity dynamic exercise with (OCC) and without occlusion (CON-LI) as well as high-intensity (CON-HI) exercise preceded by low intensity exercise. Means ±s.e.m. are given (n = 6, except for ATP where n = 5).
