现在轮滑已经成为了一项在儿童群体中十分普及的运动,很受孩子们的喜欢。练习轮滑除了一般的体育健身功效外,还能锻炼孩子的胆量,平衡能力,身体协调能力等。孩子学习轮滑不仅可以强身健体,同时也是让孩子变得活泼开朗的一项运动。

工具

进行轮滑运动应穿戴护具,穿戴装备时,一次穿戴头盔,护肘、护膝、轮滑鞋、护掌。脱掉是次序相反。

轮滑护具六件套

轮滑运动全套护具应包含:头盔、护肘、护膝与护掌。优质的护具强调包覆性、透气性、吸震效果及坚固等要求。

如何戴轮滑护具

一般来说小孩轮滑护具佩带的顺序是没太多要求的,但是护掌肯定是最后才带的。带时切忌不宜拉的很紧,当然也不能很松,适当即可。

各种护具其功能:

头盔

戴上头盔更好保护自己的头部。

护肘

这个部位很容易不小心而擦伤,尤其在练习一些高级动作。

护膝

不论是初学者或是很有经验的轮滑高手,膝盖是摔倒时着地机率最高且冲击最大的部位,如果不穿戴护具,就会很容易受伤。

轮滑鞋

穿鞋时先将脚穿入鞋内,确认脚掌全部落实后,扣好轮滑鞋上面的芭扣,轮滑鞋上是魔术贴的将魔术贴打开后在粘贴好,使其充分包裹脚部,如果轮滑鞋上面是鞋带的由前端开始拉紧鞋带,并系成活结,如并然后拉紧固定带到适宜状态即可,

护掌

初学者常会因滑倒时不当的支撑动作而造成手腕扭伤或手掌擦伤;轮滑高手偶尔也可能擦伤,戴上护掌就可避免这些不必要的伤害。

注意事项

1、轮滑鞋及护具需穿戴整齐且牢固。脱掉时将鞋子护具叠放整齐,粘好各固定带,养成物品收放整齐的好习惯。

2、鞋带不宜系得过紧,否则可能影响脚踝部件各关节的正常活动,同时也可能造成脚、踝等部位挤压受伤。

3、鞋带不宜留的过长,以免在滑行时碾压坏鞋带,同时避免影响正常滑行,造成危险,现在的大多数的轮滑鞋都改成魔术贴。

选购轮滑鞋常见的问题

1、孩子几岁开始玩轮滑比较合适?

答:通常是孩子三周岁就可以开始学习轮滑,主要还得看孩子的脚力是否足够,有些孩子虽然已满3周岁,但脚力不够,胆小和脚软,反而让还自由学习轮滑的恐惧心理,这个情况下可以让孩子再稍微大点再学。

2、如何挑选合适的轮滑鞋?

答:首先,建议尽可能选择有多年线下影响的专业轮滑鞋,尽量避免选择低端的玩具鞋及纯网络品牌的鞋子。在专业鞋的基础上,可以结合自己的目的选择。

(1)如果就自己简单滑行、刷街、代步这种简单滑行,不做动作的,选择休闲鞋就够用。

(2)如果是要送孩子去参加轮滑培训班,要一级一级跟班练上去的,一般在初级班,休闲鞋也够用

3、如何区分专业轮滑鞋与玩具鞋?

答:区分玩具鞋与专业鞋可以从以下几点进行区分:

(1)鞋壳

大多数专业轮滑鞋都以硬壳鞋为主,鞋壳使用新料,用料厚实,颜色鲜艳;玩具鞋大多数是软面鞋。如图下

(2)刀架

专业轮滑鞋的支架大部分以钢,塑钢或铝合金为主,多使用一体式刀架,更加稳定坚硬,在轮滑时不容易造成变形,使用时更安全,使用寿命更长;玩具鞋多以塑料刀架或铝合金两片式刀架为主,会偏仞,长期穿着容易让孩子变O型或X型腿。如图下

(3)轮子

专业轮滑鞋大部分采用高弹PU轮,PU厚实,弹性好,抓地性好,滑行舒畅;而玩具鞋会采用塑料轮,或者低弹轮,质地差,抓地性差,滑行不顺畅。

(4)内鞋/内胆

专业轮滑鞋内胆大多选用优质网棉/超细网棉,用料细腻厚实,包裹性好,能保护脚踝(见图15);玩具鞋大多采用劣质黑心棉,肉眼可见的粗格网布,用料粗糙单薄,包裹性差,穿着不透气,容易造成孩子脚部不适。

(5)轴承

专业轮滑鞋轴承顺畅,滑行起来声音很小,轮滑鞋落地的声音敦实而低沉;而玩具鞋轴承很涩,滑行起来声音则是噼里啪啦的。

(6)CUFF

专业轮滑鞋的CUFF设计合理,能调节松紧,穿戴方便,(如下图);玩具鞋的CUFF多使用简易魔术贴,固定不紧,滑行感较差。

专业鞋CUFF设计

4、常见的专业鞋品牌有哪些?

答:常见的专业鞋品牌有:micro、乐秀、米高、飞鹰、Rollerblade、费斯、宝狮莱、动感等。其中米高、乐秀、费斯在线下影响力较大,长期开展线下活动。在很多地区有经销商。

5、小孩子选哪种鞋子更合适呢?

对于孩子而言,如果孩子只是买来自己随便玩玩的话,力量较小,穿脱轮滑鞋时比较费力,小编建议买软壳鞋面的轮滑鞋,这样的鞋子包裹性比硬壳鞋要好,穿起来比较舒适;如果孩子只是为了休闲玩轮滑,那么建议选择透气性更好的半软壳鞋;如果小孩是在俱乐部训练或者练习环境比较复杂,还是选硬壳轮滑鞋,因为训练强度大或者滑行路面条件不是很好的话,硬壳的溜冰鞋可以更好的保护孩子的脚踝不受伤。

6、轮滑鞋尺码如何选择?

答:选购轮滑鞋与我们选购日常穿的鞋子一样,需要考虑尺码问题,建议如下。

一般儿童轮滑鞋多数都设计有尺码可调节的功能,常见的有:

S码(28-31)一般3-7岁;

M码(32-35)一般5-9岁;

L码(36-39)一般在10岁及以上。

常见的码段是这样(见下图1),部分品牌鞋子码段设计可能会有差异。

调节尺码时,只要一只手按住鞋子上的调节按钮,另一只手抓住鞋头往外拉,拉到相应的码位就可以(见下图2)。

如果正好处在一双鞋子码段的尾数,一般建议选择下一个偏大一点的码段,比如脚是31码时,可以考虑选择M码(32-35),买回来让孩子穿着试试,正常是穿上后脚后跟位置留一个手指左右的空间就算合适。如果孩子穿着稍微显大,可以垫一双鞋垫,就能解决这个问题。但不建议选择太大码数,合脚最重要。

练习方法

建议家长不要过早地让小孩学习轮滑,小朋友最佳年龄应该在三岁到八岁之间。

滑行前准备

心理准备

在学习前不要让孩子认为学习轮滑是一件多么难,多么危险的事情,要告诉孩子轮滑每个小孩子都可以学的,多给予鼓励。

提高兴趣

对着孩子问喜不喜欢,让孩子了解这项运动并且对它产生浓厚的兴趣,兴趣就是最后的老师。

注意事项

滑行中

学习站立

让孩子站在地毯上,要求脚后跟靠紧,脚尖张开,成45~60°张角;小腿向前弯曲与地面成75°夹角;双膝弯曲,大腿与小退约成150°,弯腰,大腿与上身成135°夹角。双手放膝盖上。抬头,眼睛目视前方。然后要求孩子上身放松,脚用力向下采。鞋子是垂直才在地面上,踝关节要紧张起来,不要向两侧倒,双膝分开10~15cm(只要把孩子的身体定在以上姿势,就可以立刻站稳的)。

如果孩子比较胆小,辅助者可以蹲下,双手抓住孩子的脚背,不让轮子滑动,提醒孩子把脚跟靠紧,另一个人站在孩子的背后,防止孩子不弯腰时向后摔倒。如快要向后摔倒,蹲下的辅助者,用力下下压住孩子的脚背也能起到调整的作用。

当孩子站得比较稳后,辅助者慢慢的松开孩子的脚背,让孩子自己站立。

V字站立

家长的双手抓住孩子的小脚脚成小V字(立正姿势),让孩子端坐好,双手扶住膝盖,然后身体前倾用力站起来。(对于胆子较小的孩子,要分散他的注意力,不要总是看着自己的小脚。胆子较大的孩子,要让他盯住自己的小脚,以免开小差摔倒),这个时候,要让孩子紧扶膝盖不放,家长试着慢慢松开手,让孩子独自弯腰屈膝站立。

站不稳的原因有:

1、小脚分得太开

2、小脚靠太近

3、两脚不是小八字

4、没有弯腰屈膝

5、注意力不集中,两脚用力不均匀,这个阶段站立大概1分钟(可以和孩子从1数到20)坐下休息一次,反复3-5次。

原地踏步

如果孩子能稳稳的站立30秒,我们就在原地站立的基础上,双脚脚尖朝外,双腿微微弯曲,做好准备动作后,双脚交替抬起,可逐渐加大幅度。

抬脚时重心不稳,左右晃动。

左右的晃动主要是因为学生的脚踝、腿部力量不足,以及孩子的平衡能力欠缺,而导致重心左右不稳。

解决办法:辅助者从练习者的身后扶住他腰、髋部,帮助其稳定重心,也应发展其腿部例如蛙跳或深蹲及脚踝的力量例如提踵立,从而增强脚踝,腿部的肌肉控制力。

抬脚时重心不稳,身体容易上下弹动。

当抬脚时孩子会将膝盖伸直,因此导致的重心上下变化。

平衡练习

横向跨步移动,两脚平行,双手扶在大腿上,右腿向右侧横跨一步,左腿提膝带小腿,收回靠拢。注意有个重心转移的过程,一迈腿,二重心转移,三收腿。

稳固站立

同样的方法让孩子站起来,待孩子独自站稳后,家长在孩子前方面对面引导孩子慢慢双手离开膝盖站立起来(随时准备接住,这个动作可能几次才能成功)。接下来让孩子跟家长一起做并大声数出来;

1、双手平举

2、弯腰双手扶膝盖

3、恢复站立姿势,此动作节奏由慢到快,持续5-8次并灌输给孩子一个意识(在以后的滑行中,如果感觉重向左转一点,然后右脚跟进)。记住提醒孩子,“左脚转多少,右脚就转多少”(确保始终是小八字)幅度不要太大,不然容易摔跤。转身过来后接着向前走。一般3-5分钟休息一次。

待孩子在地毯或草地上练习得比较自如后,就可以转到光滑的地面上练习(地面上不能有油、沙、水)。在地面上从第三步开始练习。等孩子自如地熟悉滑行的速度后他自己就会自然直立滑行。但在感觉要摔倒时一定要手扶膝盖或膝盖以下,保证不摔或向前摔倒(向前摔倒有护具保护)。

滑行

在滑行过程中孩子的小脚抬得越快、越高速度就越快,快速滑行时,腰弯低一些会更省力更安全。如果需要刹车,最好转弯,转弯是最好的刹车。

滑行动作的要领是左脚在前成弓步,右脚向侧蹬出,上身向前微倾斜,两臂平伸与肩同高,重心放在左脚上。然后右脚收回到左脚内侧,右脚向前滑出,左脚向后外侧蹬出,同时重心由左脚移动到右脚,收脚到右脚内侧。此外,就像我们考驾照一样,弯道滑行也很重要。转弯的时候,注意重心下降,并落在一只脚上。

注意事项:

滑行时收脚干净利落,蹬出时短促有力、爆发力强。在孩子基本掌握滑行之后,可以参加一些集体游戏以提高学习轮滑的兴趣,如蹲取物品,在孩子的身旁身后或者远处放上一些玩具,请孩子找到玩具,然后蹲下把玩具捡起来,并滑行送到前方的篮子里。还有开火车、老鹰捉小鸡等游戏也很有意思。

侧蹬滑行

由静蹲姿势开始,侧蹬腿由曲到直,向正侧方蹬出,重心放在支撑腿上,鼻子、膝盖、脚尖,三点一线。滑出收腿时候,大腿提膝带小腿,收回靠拢。两腿交换蹬出收回。

停止

在滑行中,有时需要及时停止滑行,所以在孩子初步掌握滑行基本动作的同时,就要学会停止滑行的方法。

停止的方法分:正中切法、A字停刀、T字停刀、转弯急停。

注意事项:

小朋友可以用正中切法,这是很容易掌握的一种方法,就是双脚平行,把有刹车器的那一脚向前推出,脚尖微向上,让刹车器磨到地面就可以,将刹车器愈用力的压向地面,就可以愈快停下来。记住重心一定要放低,保持在两脚中间,不可以太前或太后。转弯急停需要较好的轮滑平衡能力,不建议小孩子学。

安全跌倒

安全跌倒的训练是透过护具及全身来分散跌倒时的冲击力,跌倒时保持让身体向前扑倒,避免向后跌坐或让身体某一部分完全承受撞击,如臀部、下巴、手腕、手肘、膝盖等,以减少单一部位受伤的程度。

教练建议:身体前倾,膝盖跪下,身体趴下,以护掌触地向前滑出,并让身体同时伸展出去,然后完全扑倒在地,经过这一连串的动作后,跌倒时的撞击力会被完全分散出去,不致于使单一部位承受太多、太重的伤害。

注意事项

由于玩轮滑时腰部、膝关节、脚踝需要用力支撑身体,时间过长,容易导致局部负担过重,发生劳损,甚至会影响骨骼的正常发育。所以,正处在生长发育期的小孩子,玩轮滑时间不宜过长。儿童每天进行轮滑的时间最好在50分钟以内;

1、在选择轮滑鞋是一定要选择适合自己孩子的,轮滑的质量是关键和运动类型也很重要,刚开始买轮滑鞋建议买三百到五百左右的,买之前一定要确认所选的轮滑鞋是否过关,这也是保证小朋友安全的前提。

2、必要的安全保护措施。做任何事情,安全都是第一位的,因此,对于初学孩子,安全护具是必不可少的,主要包括:护腕、护肘和护膝,其他护具象手套、护踝、护腿、护身在参加不同的项目可以有选择的加以使用。

3、小朋友在玩轮滑时一定要选择比较平稳的场地,避免在:在树叶、碎石、水滩的这些危险的地方滑行。

4、如果遇到无法避免的低地,则试着将重心放在脚跟,保持直行滑过。

课外辅导

基础动作熟练掌握滑行是没问题的,如果还想学习一些技巧花式动作,最好是找专业的教练指导,避免练习方法错误导致孩子受伤。

专业滑轮培训

1、减少试错成本,减少孩子受伤几率,提高学成效率。

2、全面系统学习,动作标准,学会自我保护,激发更多潜能。

3、能认识更多小伙伴,培养孩子社交能力。

学习轮滑都会学习到哪些课程?以自由式轮滑教学课程为例:

一般轮滑基础班到高级班的课程都是帮助孩子正确的学习轮滑的站立姿势、滑行姿势、如何避免受伤、如何停止、如何倒滑、一些平衡和基础性的技巧教学,整套学习下来孩子能够达到无障碍的独自滑行。

花式教学课程主要是帮助想更深层次的学习轮滑的学员,花式教学的课程有一定的难度和技巧性,想学习这类课程一定要有一定的基础后再进行花式轮滑的学习。
