28-year-old woman training fencing with isolated rupture of radial collateral ligament of the metacarpophalangeal joint of the index finger

Isolated rupture of radial collateral ligament of the metacrpophalangeal joint of the index finger is a rare reported disorder, which causes radial instability of the joint. The joint stability can not be restored without surgical techniques. This report presents a case of a 28-year-old woman training fencing (foilist), representing the national team, with this kind of lesion. The patient presented with pain and instability of the MCP joint of the index finger after collision with opponent on the fencing board. The clinical and the imaging findings suggested a lesion of the radial collateral ligament. Therefore there was performed a surgery of reconstruction of damaged ligament. There was applied rehabilitation. We describe a mechanism of this kind of injuries in foilists and method of preventing renewed injury.     

In a complex sequential movement, what component of the motor program is improved with intensive practice, sequence timing or ensemble motor learning?

We investigated whether the higher maximum speed of complex athletic movements attained by experts compared with novices might solely be ascribed to the acquisition of a more efficient timing of the initiation of the simple movements that comprise complex sporting gestures. Six novices in fencing and five experts in fencing performed three experimental series: 7 trials of touche, 7 trials of lunge (control series) and 50 trials of lunge + touche (test series), where the touche and lunge were initiated with different chronological sequences imposed by the experimenter. The lunge and the touche can be assimilated to a fast forward step and to a pointing task, respectively. We compared the maximum speed of touche between the two groups, recorded by an accelerometer fixed to the hand guard of the foil, and the speed of the centre of mass obtained from a force plate. The speed of the centre of mass was not statistically different between the two groups in the control and in the test series. The maximum speed of touche was not statistically different between the two groups in the control series. In contrast, in the test series, the maximum speed of touche was higher in the fencers' than in novices' groups, while the timing of initiation of the lunge and the touche was similar. The results of the test series show that the higher maximum speed of touche of fencers compared with novices cannot solely be ascribed to the acquisition of a more efficient initiation timing in motor programming. In a complex fencing gesture, the higher maximum speed of touche following intensive practice is discussed with regard to the inhibition of negative effects linked to the "refractory period" associated with the initiation of two closely spaced motor programs.     

Nutritional status of students practicing fencing atttending sports schools

Aim

The aim of this research was to assess the influence of various factors on nutritional status in children and adolescents practicing fencing and to carry out a detailed analysis of nutritional status in the studied population, taking into account the most significant variable.

Current knowledge

One of the most important issues of human nutrition is the assessment of nutritional status of children and adolescents, especially those who practice sport. There are still a lot of gaps in the knowledge on nutritional status of young athletes. The reason for this is a variety of sports disciplines and forms of training which requires detailed research and screening of young athletes’ growth and development.

Prospects

In the studied population of children and adolescents practicing fencing typical gender differences in body stature and body composition occurring with age were observed, as well as favourable changes in blood lipid profile, glucose level and haematological indices.

Do centrally programmed anticipatory postural adjustments in fast stepping affect performance of an associated ”touche” movement?

Ensuring maximum speed in executing a sequence of two voluntary movements requires the second movement to be triggered only after some delay. This is due to the existence of a ”relative refractory period.” If the second movement is initiated during the refractory period, its speed decreases (movement time increases). In the present study we tested the existence of a refractory period during the execution of a sequence of movements involving both the upper and the lower limbs. More precisely, we examined whether the maximal speed of the touche fencing movement is affected by the anticipatory postural adjustments (APA) preceding a voluntary lunge. The touche and the lunge are similar to a pointing task and a stepping forward movement, respectively. touche consists of hitting a target with a foil at maximal velocity. The results show that (a) when the touche was initiated prior to the onset of the APA of the lunge, the maximal foil velocity remains similar to that of an isolated touche, and (b) when the touche is initiated during the development of the APA of the lunge, the maximal foil velocity is lower than in the isolated touche. Furthermore, the maximal foil velocity decreases with the temporal progression of the APA and reaches its minimal value when initiated at the time of voluntary lunge execution (’foot off’). The discussion suggests that the centrally programmed APA that are elicited in the stepping forward movement induces a refractory period which affects performance of the pointing task.

身体运动功能训练对患髌腱末端病的职业击剑运动员运动功能和平衡能力的影响

目的观察身体运动功能训练对患髌腱末端病的职业击剑运动员膝关节疼痛分级、功能动作评分和平衡能力的影响。 方法随机数字表法将24例有髌腱末端病的职业击剑运动员（患者）分为实验组和对照组,每组患者12例。对照组运动员接受常规物理治疗,实验组运动员则在常规物理治疗基础上增加身体运动功能训练。于干预前和干预8周后（干预后）对2组患者进行疼痛分级、功能动作筛查和平衡能力评定。 结果干预后,实验组膝关节NRS和FMS评分分别为（2.08±1.24）分和（16.25±0.97）分,显著优于组内干预前和对照组干预后,差异均有统计学意义（P<0.05）。干预后,实验组睁眼和闭眼单脚状态下,压力重心在X轴的摆幅、线形图总长度、最大摆幅和线形图面积与组内干预前和对照组干预后比较,差异均有统计学意义（P<0.05）。 结论身体运动功能训练能显著促进患髌腱末端病患者身体运动功能和平衡能力的恢复。
