):15-9.Thermoregulation in marathon competition at low ambient temperature..AbstractThe 1982 Aberdeen marathon race was held on a cool (12 degrees C) day on a flat, fast course. Fifty-nine of the 750 runners volunteered to take part in this study: rectal temperature of these competitors was measured within 5 min of completing the race. Venous blood samples were obtained before and immedi body weight of these subjects was also recorded before and after the race. During the race, 200 ml of fluid, either water or a glucose/electrolyte drink, was consumed at each of the seven feeding stations. The mean finishing time of the subjects was 221 +/- 37 min (mean +/- SD, range = 144-307 min). Post-race rectal temperature was 38.3 +/- 0.9 degrees C with a range of values from 35.6 degrees to 39.8 degrees C. The net weight loss was 2.02 +/- 0.72 kg equivalent to 2.9% +/- 0.8% of body weight. The correlation between post-race rectal temperature and finishing time (r = -0.234) was not stati post-race rectal temperature was significantly correlated with the time taken to complete the second half of the race (r = -0.348, P less than 0.01). No cases of heat illness were seen among the competitors. The results suggest that hypothermia rather than hyperthermia may be a problem for marathon runners competing under these conditions.PMID: 3988410

Penguin Engineering Ltd (Pel), P.O. Box 33-093, Petone, New Zealand Abstract Amplitude-dependent internal friction of polycrystalline commercial lead has been studied in wide frequency and strain amplitude ranges. The strain amplitude dependence shows two stages characterized by different recovery times. These stages are attributed to different mechanisms : dislocation - point obstacle interaction at moderate amplitudes and interaction between dislocations along with their multiplication at the high ones. Pronounced and nonmonotonous dependence of the amplitude-dependent internal friction and elastic limit on prestrain is revealed. This peculiarity is attributed to transition from relatively homogeneous dislocation distribution to the inhomogeneous one due to formation of the cellular structure.&&EDP Sciences&1996
