- ItemAquaJogging the brain: An early intervention in concussion management?(Current Research: Concussion, 2015)Mild traumatic brain injury has been shown to result in decreased cerebral blood flow. Water-based exercise has recently been shown to increase cerebral blood flow when compared to land-based exercise. It seems reasonable that the initial introduction of water-based exercise may improve the recovery and return to activity of patients who have sustained a concussion.
- ItemAn In-Depth Sports Medicine Profile of Women College Tennis Players(Journal of Sport Rehabilitation, 1995)Provides an in-depth sports medicine profile of women college tennis players and determines the relationship among an array of performance and clinical variables. Comprehensive battery of test on 38 non-restrained women.
- ItemAvulsion Fractures Involving the Cruciate Ligaments(American Academy of General Practice, 1988-08)The evaluation of a child with an acute knee injury is difficult. The injury may be an avulsion fracture involving either of the cruciate ligaments; a common cause is a cycling accident. The amount of fragment displacement dictates the management. Minimal displacement can be treated with immobilization in flexion. Larger displacement requires internal fixation, which can be accomplished arthroscopically. Rehabilitation must be early and aggressive.
- ItemEffect of Acid-Base Balance on the Growth Hormone Response to Acute High-Intensity Cycle Exercise(American Physiological Society, 1994-02)To investigate the effect of acid-base balance on serum human growth hormone (hGH) concentration after an acute high-intensity anaerobic exercise bout, 10 untrained but normally active men [age, 24.6 +/- 1.5 (SE) yr] participated in a randomized double-blind counterbalanced experiment. Each subject reported in a fasted state at the same time of day for two experimental sessions separated by 1 wk. For each session, subjects were administered a decaffeinated tea solution containing either 0.3 g NaHCO3/kg body wt [alkalosis (ALK)] or 0.04 g NaCl/kg body wt [control (CTRL)] over a 45-min ingestion period. Venous blood samples were obtained before [baseline (BL)] and 75 min after the ingestion period, as well as postexercise at 0, 5, 10, 15, 20, and 30 min. The exercise task immediately followed the preexercise blood draw and consisted of 90 s of maximal-effort cycle ergometry against an opposing force of 0.49 N (0.05 kg)/kg body wt. There were no differences between the ALK and CTRL conditions in mean or peak power output or total work during the exercise task. Whole blood pH was significantly (P < or = 0.05) elevated in ALK above CTRL at all time points except BL. Postexercise serum hGH concentration significantly increased above BL at 10, 15, 20, and 30 min in CTRL and at 20 and 30 min in ALK. The hGH concentration was significantly lower in ALK than in CTRL at 15, 20, and 30 min postexercise. These data indicate that an increase in blood hydrogen ion concentration may be partly responsible for the hGH response to acute high-intensity anaerobic exercise.
