DESCRIPTION (provided by applicant): Skeletal muscle atrophy and weakness affects nearly all of the nation's elderly and often leads to frailty, immobility, falls, fractures, and institutionalization. Numerous studies have shown that weight training involving Shortening Contraction Training (SCT) protocols can slow or even reverse this decline. Unfortunately, traditional SCT protocols commonly have low trainee compliance and can be too strenuous for many older individuals. On the positive side, recent studies show that even greater strength increases can be safely realized via Lengthening Contraction Training (LCT) which incurs a lower acute metabolic cost and results in lower rates of perceived exertion than SCT. Consequently, LCT is a particularly attractive intervention for the elderly, energetically impaired, and less athletically-motivated populations. Despite these advantages, no commercially available system exists for LCT. Therefore, during Phase I of this research project, Bio Logic Engineering, Inc. will develop an innovative computer controlled and motorized prototype to enable safe and effective weight training with advanced SCT and LCT protocols on a leg press machine. The system will be modular and adaptable to other types of stacked weight machines. Assessment of preliminary system performance will be conducted over a four week training period with two young healthy adults. The potential market for the proposed system is large considering its potential for training and assessment use in physical therapy clinics, assisted-living communities, hospitals, health clubs, recreational centers, academic institutions, and corporate wellness centers. System refinement and extensive human testing and hypothesis-based research will be conducted in Phase II.

描述（由申请人提供）：骨骼肌萎缩和无力影响几乎所有的国家的老年人，往往导致虚弱，不动，福尔斯，骨折，和机构。许多研究表明，涉及缩短收缩训练（SCT）方案的重量训练可以减缓甚至扭转这种下降。不幸的是，传统的SCT方案通常具有低的受训者依从性，并且对于许多老年人来说可能过于费力。从积极的方面来看，最近的研究表明，通过长时间收缩训练（LCT）可以安全地实现更大的力量增加，这比SCT带来更低的急性代谢成本，并导致更低的感知运动率。因此，LCT是一个特别有吸引力的干预老年人，精力受损，运动动机少的人群。尽管有这些优点，但没有用于LCT的市售系统。因此，在本研究项目的第一阶段，生物逻辑工程公司。将开发一种创新的计算机控制和电动原型，以实现安全和有效的重量训练与先进的SCT和LCT协议的压腿机。该系统将是模块化的，并适用于其他类型的堆叠重量机器。将在为期四周的培训期间对两名年轻健康成人进行初步系统性能评估。考虑到其在物理治疗诊所、辅助生活社区、医院、健康俱乐部、娱乐中心、学术机构和企业健康中心的培训和评估用途的潜力，拟议系统的潜在市场很大。第二阶段将进行系统改进和广泛的人体测试以及基于假设的研究。
