Description
技术领域: Technical field:
本发明涉及机械领域，尤其涉及体育训练和测试器械，特别涉及针对足部跖趾关节的力量训练和测试的技术，具体的是一种足部跖趾关节力量测试仪。 The invention relates to the field of machinery, in particular to physical training and testing equipment, in particular to the strength training and testing technology for the metatarsophalangeal joint of the foot, in particular to a strength tester for the metatarsophalangeal joint of the foot.
背景技术: Background technique:
跖趾关节隶属于足关节的前部，由跖骨头和近节趾骨底构成，属于椭圆关节，能绕额状轴做屈曲（勾足趾）和伸展（伸足趾）运动，也能绕矢状轴做轻微的外展（五趾骨展开）和内收（五趾骨并拢）运动。另外，跖趾关节屈曲、伸展使得跖骨向下、上移动，可增加或减少足前弓的弧度，使得足前部凹陷或塌陷，改变足弓形态。而且，跖趾关节的伸展范围大于屈曲(Creighten & Oleson.足底筋膜炎跑步者跖趾关节活动范围的评估. 矫形与运动疗法杂志, 1987, 8(7): 357-361 )：主动伸展的范围是50°-60°，主动屈曲的范围是30°-40°，被动伸展在迈步最后阶段（蹬离地面）及其重要，角度可达甚至超过90°。 The metatarsophalangeal joint belongs to the front part of the foot joint and is composed of the metatarsal head and the base of the proximal phalanx. Slight abduction (expansion of the five phalanges) and adduction (approaching of the five phalanges) of the phalanx. In addition, the flexion and extension of the metatarsophalangeal joints make the metatarsals move downward and upward, which can increase or decrease the arc of the arch of the foot, make the front of the foot concave or collapse, and change the shape of the arch of the foot. Moreover, the extension of the metatarsophalangeal joint is greater than the range of flexion (Creighten & Oleson. Assessment of the range of motion of the metatarsophalangeal joint in runners with plantar fasciitis. Journal of Orthopedics and Sports Therapy, 1987, 8(7): 357-361 ): Active extension The range of active flexion is 50°-60°, the range of active flexion is 30°-40°, passive extension is extremely important in the final stage of stride (kicking off the ground), and the angle can reach or even exceed 90°.
在研究下肢运动时，现有技术经常关注的都是下肢三大关节：髋、膝、踝；即使涉及到足部，也仅仅是距上关节和距下关节的运动，大多还是足屈曲运动。而对于走、跑、跳的足屈曲运动，动作最终的发生必定是在跖趾关节，因此对于跖趾关节的研究不可或缺（Stefanyshyn & Fuscoc.通过增加鞋屈曲刚度提高短跑表现[J]. 运动生物力学杂志, 2004, 3(1): 55-66. ）。而近年来，在一些较高竞技水平的国家，不少跑、跳项目（具有蹬离动作）的教练员强调跖趾关节屈伸的活动度及其趾屈肌力量的训练，用以协助足部蹬离地面的同时增加包括相邻关节在内的力量输出，从而获得较大的支撑反作用力，提高运动表现（Goldmann, Sannom, Willwacher, et al.跖趾关节屈曲肌力能够增强运动表现的潜在可能[J].体育科学杂志, 2013, 31(4): 424-433.） When studying the movement of the lower limbs, the prior art often pays attention to the three major joints of the lower limbs: hip, knee, and ankle; even if the foot is involved, it is only the movement of the supratalar joint and the subtalar joint, and most of them are foot flexion movements. For the foot flexion movement of walking, running, and jumping, the final movement must be at the metatarsophalangeal joint, so the research on the metatarsophalangeal joint is indispensable (Stefanyshyn & Fuscoc. Improving sprint performance by increasing shoe flexion stiffness[J]. Journal of Sports Biomechanics, 2004, 3(1): 55-66. ). In recent years, in some countries with a higher level of competition, many coaches of running and jumping events (with push-off action) have emphasized the flexion and extension of the metatarsophalangeal joints and the training of toe flexor strength to assist the foot Increase the power output including adjacent joints while kicking off the ground, so as to obtain greater support reaction force and improve sports performance (Goldmann, Sannom, Willwacher, et al. The flexion muscle strength of the metatarsophalangeal joint can enhance the potential of sports performance Possibly [J]. Journal of Sports Science, 2013, 31(4): 424-433.)
虽然近年来，体育研究者们开始重视跖趾关节的肌肉力量，但是没有一个具体的方案来测试并量化这些肌肉的力量；根据国家专利局检索中心专利查询也没有发现相关测试仪或实施例，所以本发明的提出就是为了解决上述问题：测试并量化跖趾关节的屈曲力量，为教练员和运动员提供可靠数据以明确训练目标。 Although in recent years, sports researchers have begun to pay attention to the muscle strength of the metatarsophalangeal joint, there is no specific plan to test and quantify the strength of these muscles; according to the patent query of the National Patent Office Search Center, no relevant tester or embodiment has been found. Therefore, the present invention is proposed to solve the above problems: test and quantify the flexion strength of the metatarsophalangeal joints, and provide reliable data for coaches and athletes to clarify training goals.

本发明的工作原理是： The working principle of the present invention is:
座椅、固定架、悬挂架和踏板通过底盘连成一体。座椅的高度可根据受试者的小腿长度调节：要求受试者在测量足部跖趾关节力量时，身体保持正直、面朝正前方，双手放于座椅两侧扶手上，大腿与身体成90°，小腿与大腿成90°，踝关节角度为90°。腿部固定架在大腿近膝关节处固定小腿，使小腿不能上下移动，排除踝关节运动的可能。通过固定带将受试者的足固定于底板上的脚跟限位板上，脚跟限位板可根据受试者脚长的不同来调节，以保证足部（中部和后部）不能上下、左右和前后移动。 The seat, fixed frame, suspension frame and pedals are integrated through the chassis. The height of the seat can be adjusted according to the length of the calf of the subject: when measuring the strength of the metatarsophalangeal joints, the subject is required to keep his body upright, face straight ahead, put his hands on the armrests on both sides of the seat, and keep his thighs in contact with his body. At 90°, the calf and thigh are at 90°, and the ankle joint angle is 90°. The leg fixing frame fixes the calf near the knee joint of the thigh so that the calf cannot move up and down and excludes the possibility of ankle joint movement. The subject's feet are fixed on the heel limit plate on the bottom plate through the fixing belt. The heel limit plate can be adjusted according to the length of the subject's feet to ensure that the feet (middle and rear) cannot be up and down, left and right and move back and forth.
拉力传感器悬挂在悬挂架上，下连踏板。踏板可上下活动以测量足部跖趾关节的屈曲力量；也可左右活动以根据受试者跖趾关节斜角的不同来调整踏板的倾斜角度(±30°)，使得受试者的足部跖趾关节处于最佳发力角度；还可前后移动以根据受试者足趾的长度来调节踏板的前后位置，并记录跖趾关节到拉力传感器垂直线的距离(L)。测试时，要求受试者听到开始口令后，尽全力用跖趾下压踏板并持续3-5秒，此时计算机通过数据线采集并保存拉力传感器测得的足部跖趾关节的屈曲力(F)。 The tension sensor is suspended on the suspension frame and connected with the pedals. The pedal can be moved up and down to measure the flexion force of the metatarsophalangeal joint of the foot; it can also be moved left and right to adjust the inclination angle of the pedal (±30°) according to the inclination angle of the subject's metatarsophalangeal joint, so that the subject's foot The metatarsophalangeal joints are at the optimal force angle; they can also move forward and backward to adjust the front and rear positions of the pedals according to the length of the subject's toes, and record the distance (L) from the metatarsophalangeal joints to the vertical line of the tension sensor. During the test, after hearing the start password, the subject is required to press down on the pedal with the metatarsophalangeal with all his strength and last for 3-5 seconds. At this time, the computer collects and saves the flexion force of the metatarsophalangeal joint of the foot measured by the tension sensor through the data line. (F).
采集到以上数据之后，可通过如下公式来计算人体跖趾关节的屈曲力矩(M)，以反映跖趾关节的屈曲力量特征。 After collecting the above data, the flexion moment (M) of the human metatarsophalangeal joint can be calculated by the following formula to reflect the flexion force characteristics of the metatarsophalangeal joint.
M = L × F M = L × F
