Innovation in training equipment is important for increasing training effectiveness, performance and changes in body composition, especially in wheelchair users with paraplegia. The main objective of a workout session is to induce an adaptation stimulus, which requires overload of involved muscles by voluntary effort, yet this overload may be highly influenced by the size of the spinal cord lesion. Krancykl construction is designed to allow exercise on any wheelchair and with adjustable height or width of crank handles, where even the grip handle may be altered. The aim of this study was to determine the differences in body composition, performance and the rate of perceived exertion (RPE) in paraplegics with a different level of paralyses after a 12 week training programme of a unilateral regime on Krankcycle equipment (a crank machine). The study sample included four men and one women at a different spine lesion level. The 12 weeks programme was successfully completed by four participants, while one subject got injured during the intervention process. Three participants were paraplegics and one was quadriplegic with innervation of the biceps humeri, triceps humeri and deltoideus. The Krankcycle 30 min programme was followed by four other exercises, which were performed after themselves rather than in a circuit training manner as the latter would result in much longer rest periods between exercises, because paraplegics have to be fixed by straps during exercise on hydraulic machines. The RPE after the workout decreased following the twelve week adaptation period.
训练设备的创新对于提高训练效果、运动表现以及身体成分变化至关重要，尤其是对于截瘫轮椅使用者。锻炼课程的主要目标是诱发适应性刺激，这需要通过自主努力使相关肌肉过载，但这种过载可能会受到脊髓损伤程度的高度影响。Krankcycle健身器的设计允许在任何轮椅上进行锻炼，并且曲柄把手的高度或宽度可调，甚至握把也可以改变。本研究的目的是确定在Krankcycle设备（一种曲柄健身器）上进行为期12周的单侧训练计划后，不同瘫痪程度的截瘫患者在身体成分、运动表现和主观用力程度（RPE）方面的差异。研究样本包括四名男性和一名女性，他们的脊柱损伤程度不同。四名参与者成功完成了为期12周的计划，而一名受试者在干预过程中受伤。三名参与者为截瘫患者，一名为四肢瘫痪患者，其肱二头肌、肱三头肌和三角肌有神经支配。在Krankcycle健身器上进行30分钟的训练后，接着进行另外四项练习，这些练习是依次进行的，而不是采用循环训练方式，因为后者会导致练习之间的休息时间长得多，因为截瘫患者在液压器械上锻炼时必须用绑带固定。经过12周的适应期后，锻炼后的主观用力程度降低。
