Intense physical exercise can lead to micro-damage to tissues and activation ofinflammatory processes, the body's natural response to exercise-related metabolic stress.Monitoring inflammation and fatigue will enable the observation of athletes in terms ofpost-exercise regeneration and muscle adaptation to physical effort. The obtained resultswill allow for estimating the level of fatigue, minimizing the risk of injury, and willshow the rate of post-exercise regeneration or its absence.
The study will involve 40 members of the Polish Youth Rowing Team, both sexes, aged
19-23. The study will be held on three dates related to the specifics of the athletes'
training cycle, i.e. in the preparatory period (March), the competition period (June),
and the detraining period (November). The participants will perform an intensive exercise
test on a rowing ergometer (manufacturer: Concept II, USA), covering a distance of 2,000
meters in the shortest possible time. The study will involve 40 members of the Polish
Youth Rowing Team, both sexes, aged 19-23. Each time, before starting the exercise test,
a non-invasive anthropometric analysis will be performed using the TANITA MC-780MA body
composition analyzer (tanita Japan), to determine the body composition: percentage of
body fat, body fat mass, lean tissue mass, muscle mass, body water and body mass index
(BMI). On the three indicated dates, before and after the stress test, capillary blood
(ear lobe) from the cubital vein will be collected from the participants. Using
immunoenzymatic ELISA tests, the following will be determined: EPO (erythropoietin), VEGF
(vascular endothelial growth factor), CRP (C-reactive protein), glycogen, hypoxanthine
(Hx). Glucose level will be determined using an Accu-Chek Active glucometer (Roche,
Germany).
Other: Physical effort
The examined rowers will be subjected to an effort on a rowing ergometer, consisting of
covering a designated distance in the shortest possible time.
