SummaryStudy aim: To determine the level and internal structure of profiles of coordination motor abilities in elite judokas and badminton players compared to a group of non-athletes.Material and methods: The material for the study was the results collected from 12 competitors of the Polish national badminton team (age: 22.7 ± 4.5), 10 members of the national judo team who represented mean weight categories (age: 23.0 ± 3.3) and 25 non-athletes, who were male university students of the Faculty of Physical Education and Sport (age: 23.0 ± 0.8). The scope of the study included basic somatic features and selected coordination motor abilities measured by means of computer tests.Results: Statistically significant differences between badminton players and judokas were obtained for reaction times (visual, auditory and selective) as well as spatial orientation. In all cases, a higher level was found for badminton players. Furthermore, analysis of differences between badminton players and non-athletes revealed statistically significant differences only for the selective reaction time. A substantial differentiation of the internal structure of the models of coordination motor abilities was obtained. This pattern was particularly noticeable in the group of judokas and badminton players, where the difference between characteristics was ca. 0.76 SD. Substantially smaller differences (0.21 SD) between particular variables included in the coordination profile were found for non-athlete university students.Conclusion: The lower results of the elite judokas show the need for developing the coordination motor abilities during training. The largest reserves are to be found in raising the level of reaction times and spatial orientation.

“…It should be emphasised that various testing methods can produce different results. In family studies based on the EUROFIT method ("flamingo balance"), which compared balance parameters between parents and their children, there was no significant correlation when the results of fathers and mothers were compared to the results of their sons and daughters (Jaworski et al, 2010). However, the paper did not detail how the measurements were made.…”

Background: The literature data suggest that balance control is genetically determined, however the data are inconsistent with respect to correlations in balance parameters among adult relatives.Therefore, the aim of the present study was to identify correlations between fathers and their adult sons in chosen balance parameters. Moreover, we tested how the relationships in balance between fathers and their adult sons change following fatigue.Methods: The balance parameters were measured twice: before and immediately after the fatigue procedure (treadmill running to exhaustion) with the pedographic platform in two groups of relatives and correlated for 30 pairs father-adult son.Results: The positive significant correlations were found for parameters describing deflection in the sagittal plane: the average deflection of center of pressure progression (COPP) and average value of COPP velocity in sagittal plane as well as the average value of velocity of COPP, the length of COPP trajectory and the surface area of the trajectory covered by COPP, both before and after the fatigue procedure. There were no significant correlations between lifestyle of participants and balance parameters.Conclusions: In summary, our study found numerous correlations in balance parameters related to deflection in the sagittal plane between fathers and their adult sons. These correlations were not abolished by fatigue. Our results suggest that the ability to maintain balance is influenced by genetics. This conclusion can be useful in many sports in which the ability to maintain balance influence on sports score. BackgroundBalance and human body orientation are dependent on multiple sources of afferent and efferent information about ongoing and intended patterns of movement and posture. Exposure to unusual forces and patterns of sensory feedback alters the normal relationship between patterns of alpha and gamma activation of antigravity muscles, muscle spindle activity, and movements of the body, which may evoke illusory feelings of motion and balance disorders (Lackner and Graybiel, 1984; Young, 2003). Maintaining balance is a process that involves multiple receptors; namely, the vestibular

Numerous motor abilities depend on the activity of proprioceptors, which has been suggested to be genetically determined. To test this hypothesis, the control of torque generated by knee extensors and knee position was studied in 30 father-son pairs both before and immediately after running. After stabilisation of the participant in a sitting position, the knee joint of his dominant leg was flexed to 90°, and the maximal voluntary torque (MVT) of the dominant knee extensors under static conditions was measured. The participant then tried five times to produce 50% of the MVT. Next, the participant extended the knee to 45° five times without visual control. Significant correlations between the reproducibility of successive trials for groups of fathers and their sons were found. The correlation coefficients for the repeatability of the knee extension torque were 0.69 (confidence interval [CI] = 0.45-0.84; P < 0.01) and 0.75 (CI = 0.54-0.87; P < 0.01) before and after the fatiguing exercise, respectively, whereas the coefficient for the reproducibility of positioning the knee was 0.49 (CI = 0.16-0.72; P < 0.01) after the fatiguing exercise. Our results indicate a significant influence of hereditary factors on the control of limb torque and position.
