- W4294798561 abstract "INTRODUCTION: The use of thermography in sports might help prevent muscle and joint or tendon injuries. In overuse or overtraining the local temperature of the affected areas may change, denoting Inflammatory (hyperthermia) or degenerative (hypothermia) problems and, it is necessary to evaluate the cause of the thermal alteration before an injury occurs. PURPOSE: To associate comparatively the thermography pattern with medical and self-perception of fatigue and other clinical-anthropometric co-variables generated by training of Olympic long-distance runners. METHODS: The descriptive observational study involved 6 athletes(3 Kenyans, 2 South Koreans and 1 Brazilian), 22-33 yrs old males, BMI = 19.6 + -1.4 kg/m2, REE = 1509 + -54 kcal/d, long-distance runners. The 40 min(8x2km, 40 sec. walking rest) training was conducted in a 400 m olympic track (in Kenya), at 7:00 am, 16 °C temperature and 23% humidity in altitude of 2400 m. Measurements of body weight, Borg’s perceived exertion scale (PES), medical evaluation of injury (MEI) graded as 0(absence) to 3(severe) and image thermography-IRT(FLIR - termo system camera (model T420cx with thermic resolution of 320 X240(76800PIXELS and range temperature -20 to 650°c/-4 to 1202°f). All measurements were made at baseline and end of the training. Statistical analysis was performed for p = 0.05. RESULTS: The 40 min/16 km training resulted in 0.85 + - 0.42 kg body-weight loss and 1.48 (0.01-2.37)% dehydration. MEI varied from 0(2 athletes), 1(2 athl.), 2(1 athl.) and 3(1 athl.) and were in agreement with PES that varied from 2 to 5 and IRT 9 to 15. IRT correlated with PES(r = 0.83, p = 0.03) and % dehydration (r = 0.72, p = 0.04), but not with BMI (r = 0.19, p = 0.71). CONCLUSIONS:IRT is a fast and safe tool for injury prevention in long-distance runners, comparable to other classical approaches and, modified by the dehydration grade irrespective of BMI of the athletes.Acknowledgements: ABDA, Brazilian CNPq and CAPES" @default.
