Effect of Exercise Intensity on Skeletal Muscle AMPK ...

The effect of exercise intensity on skeletal muscle AMP-activated protein kinase (AMPK) signaling and substrate metabolism was examined in eight men cycling for 20 min at each of three sequential intensities: low (40 ± 2% V o2 peak), medium (59 ± 1% V o2 peak), and high (79 ± 1% V o2 peak). Muscle free AMP/ATP ratio only increased at the two higher exercise intensities ( P < 0.05).

Abstract. Phosphorus (P) uptake by plant roots depends on P intensity (I) and P quantity (Q) in the soil.The relative importance of Q and I on P uptake is unknown for soils with large P sorption capacities because of difficulties in determining trace levels of P in the soil solution. We applied a new isotope based method to detect low P concentrations (<20 µg P l −1).
