Nowadays, the use of insoles in sport practice have been recognized to decrease the foot and lower limb injury patterns. The aim of this study was to analyse the effect of four types of hardness insoles (HI) in the activity patterns of the hip and thigh muscles (HTM) in motoriders during motorcycling sport. The study was a crossover trial. Subjects were elite motoriders. The mean age was 33 ± 5.14 years. Electromyography (EMG) of hip and thigh muscles (HTM) data was registered via surface while subjects were riding on an elite motorcycle simulator. Subjects had to complete different tests with randomly hardest insoles (HI: 1: only polypropylene (58° D Shore); 2: Polypropylene (58° D Shore) with selective aluminium in hallux and metatarsal heads (60 HB Brinell hardness); 3: Ethylene vinyl acetate (EVA) (52° A Shore); and finally, 4: Ordinary EVA (25° A Shore) as the control. EMG patterns of the HTM, riding on an elite motorcycle simulator, showed the lowest peak amplitude with the insoles with polypropylene and selective aluminium. Using the hardest insoles in our study (selective aluminium) the EMG amplitude peaks decreased in all HTM.
如今，在运动实践中使用鞋垫已被证明可以减少足部和下肢受伤的模式。本研究的目的是分析在摩托车运动中，四种硬度鞋垫（HI）对骑乘者髋关节和大腿肌肉（HTM）活动模式的影响。该研究采用交叉试验设计，研究对象为精英摩托车骑手，平均年龄为 33 ± 5.14 岁。当受试者在精英摩托车模拟器上骑行时，通过表面肌电图（EMG）记录髋关节和大腿肌肉（HTM）的数据。受试者必须使用随机最硬的鞋垫完成不同的测试（HI：1：仅聚丙烯（58° D 肖氏硬度）；2：在拇趾和跖骨头部具有选择性铝的聚丙烯（58° D 肖氏硬度）（60 HB 布氏硬度）；3：乙烯-醋酸乙烯酯（EVA）（52° A 肖氏硬度）；最后，4：普通 EVA（25° A 肖氏硬度）作为对照。在精英摩托车模拟器上骑行时，HTM 的肌电图模式显示出使用具有选择性铝的聚丙烯鞋垫时的最低峰值幅度。在我们的研究中使用最硬的鞋垫（选择性铝）时，所有 HTM 的肌电图幅度峰值都降低了。
