Physiological Adaptations During A One Week Junior Elite Weightlifting Training Camp

The physiological effects of a one wk training camp were assessed using elite US junior weightlifters <n=14; age= 18.5± 1.4 yrs, Ht= 169± 8 cm, body mass= 72± 10 kg,¼ fat= 6t 2, LBM= 6?± 9 kg). T~e vari~bles used to assess training status included Triglycerides <TG>, Total Cholesterol <T-chol), HDL-C, T-chollHDL-C, Minerals, Glucose <GLU), Testosterone (Tl, Estradiol <E~>, Cortisol (Cl, Growth Hormone (GH), TIC, TIE~ and Ammonia (NH~>- Dietary factors were assessed by dietary recall over 3 alternate days. Blood Lipids, Glucose and Ammonia were measured by centrifugation and spectrophotometric methods. Hormones were measured by RIA. Blood was drawn after a 12 hr fast on day 1 and on day 8. One wk of camp produced significant changes (p < 0.05) in several variables. No other variables were significantly different. Several individual TIC ratios decreased by 25 ¼ or greater. These data are indicative of the early stages of overtraining.
