Resting biochemical parameters throughout 12-day training period at mild altitude (2300 m)
Journal Title: Journal of Combat Sports and Martial Arts - Year 2010, Vol 1, Issue 1
Abstract
[b]Introduction.[/b] The study was carried out to investigate changes in selected morning biochemical blood parameters in female judo players during their 12-day training camp at mild altitude, 2300m above sea level.[b]Material and methods.[/b] Elite female judo players (n=12) were studied on the selected days of altitude training period, which lased 12 days. The athletes lived and exercised on 2300m above sea level. That training was undertaken after 1-month detraining period. Plasma kreatine kinase (CK) glucose (G) and urea (U), and hematocrit (Hct) were assessed in the morning of the selected day of the training period. At the beginning (the 2nd 3rd and 4th day) females realised trainings of less intensity than that usually performed during retraining at see levels.[b]Results. [/b]After first night sleep at altitude, the levels of G, CK and U, and values of Htc were lower compared to those recorded on the next days. Significant correlations was found between G and CK on the first day of the camp (r=0.641*, n=12) as well as during the whole period consisted of 7 monitored days (0.587*, n=84). Body mass was correlated with basal plasma CK (the first day, r=0.940*, n=12) and on the whole period (r=0.911*, n=84). The decrease of blood volume during successive days manifested itself as the rise of Hct. During the whole period, G and U were less fluctuating variables than CK. That suggests lower substantial variation of metabolism but higher changes of muscle soreness.[b]Conclusions. [/b]Altitude training resulted in progressive dropped plasma volume and moderate fluctuations of measured variables.
