Blood parameters as a measure for controlling physical performance of young Algerian cyclists (U23 category)

Abstract

Background and Study Aim. The use of blood parameters in monitoring athletes is an essential but an unstandardized component of managing athletic preparation. This study aims to describe and evaluate typical measurements and responses observed while monitoring elite cyclist during a training camp. The reported observations might contribute in constituting a scientific support for other practitioners to employ.
 Material and Methods. 35 elite cyclists from the Algerian National team aged 16 – 23 years participated in this study. Peripheral fasting blood samples were collected in resting after 24 hrs of physical inactivity and outside competitions. Complete blood count (CBC) and hormonal index values (Cortisol, Testosterone, Probnp and TnT) were tested twice before and after the training camp. The statistical data were analysed by the SPSS software version 22.0.
 Results. The observed rates of change were significant (p<0,01, p<0,05) for most erythrocyte variables, except for leukocyte and platelet distribution levels. Hormonal values recorded for Troponin (↓92,78%, p=0,000) and Cortisol (↓11,85%, p=0,000) remained significantly as an anticipatory response to competition. The responses of the ProBnp and testosterone were not statistically significant and experienced a different response with regards to their kinetics.
 Conclusion. This study is further support suggesting a viable approach to monitoring physical performance index in elite athletes. The results imply that reducing volume while increasing intensity of training just before competition can enhance performance during short preparation periods.
