It has been suggested that a prior bout of high-intensity exercise has the potential to enhance performance during subsequent high-intensity exercise by accelerating the O(2) uptake (Vo(2)) on-response. However, the optimal combination of prior exercise intensity and subsequent recovery duration required to elicit this effect is presently unclear. Eight male participants, aged 18-24 yr, complet...
results there were significant differences between the groups in subjective labor pain scores (except vas 4) (p < 0.001). the duration of the phase one (3 cm dilatation to full dilatation) and phase two (full dilatation to birth) in the acupressure group was shorter than the control group (phase one, 225 min and 320 min, respectively; phase two, 15 min and 20 min, respectively; both p < 0.001)....
