Ice Slurry Ingestion Lowers Thermoregulatory Strain in Wheelchair Tennis Players During Repeated Sprint Intervals in the Heat.

PURPOSE: To examine the efficacy of per-cooling via ice slurry ingestion (ICE) in wheelchair tennis players exercising in the heat. METHOD: Eight wheelchair tennis players undertook sprints (4 sets of 10 × 5 s over 40 min) in a hot environment (∼32 °C), interspersed by 3 boluses of 2.67 g·kg (6.8 g·kg total) ICE or drinking temperate water (control condition). Athletes performed an on-court test of repeated sprint ability (20 × 20 m) in temperate conditions immediately before and 20 minutes after the heat exposure, and time to complete each sprint as well as intermediate times were recorded. Gastrointestinal and weighted mean skin and forehead temperatures were collected throughout the heat exposure, as were thermal sensation, heart rate, and blood lactate concentration. Sweat rate was calculated from body mass changes and fluid/ice intakes. RESULTS: Compared with the control condition, ICE resulted in a significantly lower gastrointestinal temperature (95% CI, 0.11-0.17 °C; P < .001), forehead temperature (0.58-1.06 °C; P < .001), thermal sensation (0.07-0.50 units; P = .017), and sweat rate (0.06-0.46 L·h-1; P = .017). Skin temperature, heart rate, and blood lactate concentration were not significantly different between conditions (P ≥ .598). There was no overall change preheating to postheating (P ≥ .114) or an effect of condition (P ≥ .251) on repeated sprint times. CONCLUSIONS: ICE is effective at lowering objective and subjective thermal strain when consumed between sets of repeated wheelchair sprints in the heat. However, ICE has no effect on on-court repeated 20-m sprint performance.

First year of practice visits for the Rural Depression Anxiety Research and Treatment General Practice program.

OBJECTIVE: To describe the first 12 months activities of a key component of a General Practice Psychiatry program - the GP practice visit. DESIGN: Questionnaire to evaluate effects on participating general practitioners practice. SETTING: Rural group general practices. SUBJECTS: Thirty-two general practitioners in the Loddon Campaspe Southern Mallee region in Victoria. INTERVENTIONS: Practice visits involved a combination of each of three key activities: primary consultation, secondary consultation and/or case discussion and formal teaching. RESULTS: General practitioners reported a variety of changes in their practice as a result of the visits. CONCLUSION: Practice visits appear to be a useful means of influencing GP's practice. Further work is required to determine whether such changes are accompanied by demonstrable benefits in patient outcome. WHAT IS ALREADY KNOWN: Several models to assist GPs effectively manage mental health problems have been described. These models require regular contact and so have had limited utility in rural settings. WHAT THIS STUDY ADDS: This study suggests that infrequent contact or input, based on well established models, can alter GP's clinical behaviour.

A Graduate Certificate and Master in General Practice Psychiatry by distance education--1998-2001.

BACKGROUND: The General Practice Psychiatry Program is a collaborative initiative between two universities and two professional colleges. Since 1998 it has offered general practitioners a one year part time Graduate Certificate, and a two year Master of General Practice Psychiatry. The learning is by distance education and multimode, including text packages sent out, tapes, teleconferences and two annual residential weekends with role plays and didactic teaching. OBJECTIVE: To describe the development of a Graduate Certificate and Master in General Practice Psychiatry. DISCUSSION: The program has been well supported with 141 general practitioners enrolling in the Graduate Certificate and 48 in the Masters during 1998-2001. General practitioners have been enrolling from around Australia, with rural, female and more experienced GPs predominating.
