Abstract: The distribution of whole-body O2 supply during severe hypoxia and recovery and its relation to the regional distribution of O2 deficit and repayment was studied. Mongrel dogs were anesthetized, paralyzed, and ventilated to maintain an end-tidal PCO2 between 35 and 40 Torr. In one group, the alpha- and beta-adrenergic receptors were blocked to eliminate neural and humoral adrenergic influences. In a second group, alpha-adrenergic receptors were stimulated to decrease O2 delivery by excessive vasoconstriction. In a third group, beta-adrenergic receptors were stimulated to increase O2 delivery. Whole-body and hindlimb muscle O2 uptake and vascular responses were measured during normoxic control, 15 or 30 min of severe hypoxia (9% O2 in N2), and 20 or 30 min of normoxic recovery, respectively. The whole-body O2 deficit and excess O2 uptake in recovery were partitioned into muscle and nonmuscle areas. The data showed that neural or humoral influences had little effect on the regional distribution of the total O2 deficit and O2 excess in recovery. The O2 deficit could be decreased somewhat by increasing delivery, but the amount of excess O2 used in recovery was unaffected. This suggested that the excess O2 use in recovery was more a function of an energy deficit during hypoxia and not an O2 deficit.

Abstract: Because of their roles in motility regulation and energy transport, calcium and creatine phosphate were examined for their effects on sperm motility and velocity in specimens of normal donors. Semen or migrated sperm fractions were incubated with of 1 mmol of calcium, 5 mmol magnesium, and 10 mmol of creatine phosphate (n = 28) or in the presence of 4 mumol of Verapamil, calcium, and creatine phosphate (n = 10). The samples were subjected to multiple exposure photography (four picture frames of two different drops) at 0, 1, 4, or 5 and at 10 hours and sperm motility and velocity were analyzed. In both calcium and calcium-creatine phosphate conditions, sperm motility and velocity were significantly increased, compared with control values (P = between less than 0.001 and 0.05). Sperm motility declined following Verapamil exposure, but the motility values remained at the level of the control in the presence of additional calcium or creatine phosphate. The effects of calcium and creatine phosphate take place rapidly; within 1 minute all improvements in sperm velocity and motility are fully achieved. There is no loading effect of calcium, and when the sperm is transferred into media without the additional calcium, the velocity decreased to that of the initial control value. Magnesium alone had no effect on motility or velocity. These experiments indicate that calcium or creatine phosphate can support sperm motility and velocity at a significantly increased level. Thus the addition of calcium or creatine phosphate to the insemination media may enhance the fertilizing capacity of sperm during in vitro fertilization or gamete intrafallopian transfer procedures.

Abstract: Stabilization of the ankle joint is used as a deterrent to injury, however, insufficient or excessive ankle control can cause negative effects. This study determined the effects of systematic changes in ankle and subtalar joint stabilization on performance through an obstacle course. Data were collected on six subjects as they completed two test procedures. Ankle range of motion in the sagittal and frontal planes was determined using a modified Inman apparatus. Completion time through an obstacle course, set up on a basketball court, was used as a measure of performance. High-top basketball shoes were constructed with pockets which allowed strips of plastic (stiffeners) to be positioned just anterior and posterior to the medial and lateral malleoli. Four shoe conditions were used including the shoe with no stiffeners. Significant differences (P less than 0.05) in eversion, flexion, and inversion were found between the shoe conditions. A general trend of decreased range of motion with increased restriction was observed. Significant differences (P less than 0.05) in performance were found between the shoe conditions, with a general trend of increased times with increased restriction. These results indicate that systematic changes in the range of motion of the ankle and subtalar joints can measurably affect performance.
