THE USABILITY OF ANABOLIC-CATABOLIC INDEX IN ASSESSMENT OF ICE HOCKEY PLAYERS' PERFORMANCE
Journal Title: Medycyna Sportowa - Year 2010, Vol 26, Issue 1
Abstract
[b]Background.[/b] The aim of the study was to assess the usability of testosterone-to-cortisol (T/C) ratio in modifying individual training programs[b]Materiał and methods.[/b] The research involved 16 ice hockey players during the direct training in the preparation and competition period. Two series of tests were performed: the refusal test and after 21 days the 6-minute critical power test (the power determined during threshold test), the subjects had the-ir blood sampled before and after each test. Serum cortisol and testosterone concentrations were determined using radioimmunoassay (RIA) method.[b]Results.[/b] The average total work performed by ice hockey players in the refusal test was 3228.2 ±500.2 J/kg and in the 6-minute critical power test was 1419.6±163.3 J/kg. The average hormone concentrations in the first series before the exercise were: corrected cortisol - 395.0±148.8 nmol/l, testosterone- 21.5±8.6 nmol/l and after the exercise: 489.5±160.4 nmol/l and 18.0+5.7 nmol/l, respectively The average percentage change in T/C ratio was 17.03. The training program was modified based on the in-dMdual results of 10 players. In the second series, corrected cortisol concentration before the exercise was 390.5±206.4 nmol/l and testosterone concentration was 13.73+4.55 nmol/l. After the exercise test these values were 502.1+157.3 nmol/l and 19.2+5.5 nmol/l, respectively The average percentage change in T/C ratio was 17.19.[b]Conclusions.[/b] Acceptance threshold of anabolic-catabolic index as 30% change to individual training program modification in ice hockey players isjustified.
