Abstract
Control of static balance was studied in wrestlers (n = 31) in the normal state and against the background of physical fatigue, i.e., before and after a bicycle PWC 170 test, respectively. The static balance was evaluated using a Ritm force platform (Russia) during normal basic stance (BS) and static strain (half-squatting position (HS) with the eyes open). Before physical exercise, i.e., during BS, the differences in postural control of the center of pressure (CP) between athletes and control subjects (n = 40) were nonsignificant. In the HS position, both linear and angular sway velocities of CP (LSV and ASV, respectively) were significantly lower in wrestlers (p < 0.001), and these parameters were negatively correlated with the PWC 170 index (r = −0.454 and r = −455, p < 0.001 for LSV and ASV, respectively), which suggests that up to 20% of the sway velocity variance during static strain is dependent on the working capacity of the subjects. After the PWC 170 test, the sway velocities of CP increased in both groups during BS (p < 0.01) and HS (p < 0.001), which testifies to the important role of muscular fatigue in the decrease in postural stability in both groups. During BS, an increase in LSV and ASV was about the same in both groups; however, during HS, an increase in the sway velocities of CP after PWC 170 was lower in wrestlers (the intergroup differences at p = 0.037 and p = 0.008 for LSV and ASV, respectively); this parameter was negatively correlated with the recovery of the heart rate (HR) after the bicycle test (r = −0.378, p < 0.001 and r = −0.265, p < 0.05 for LSV and ASV, respectively), which suggests that rapid recovery contributes to a certain extent (about 6.5–14.2%) to the postural stability during static strain of wrestlers against the background of their physical fatigue.
