Abstract

Purpose

This study aimed to evaluate feasibility and early effects of moderate intensity bed-cycling eccentric training on healthy individuals, and establish whether this training modality could be implemented into bedridden patients' routine care.

Methods

Longitudinal study with prepost exercise intervention measurements. The development of a bed-adapted eccentric ergometer allowed to conduct five training sessions during 3 weeks at increasing intensity on 11 healthy individuals. Force-speed relationship, maximal voluntary knee extension force and neural activation of subjects were evaluated before and after the programme.

Results

Five training sessions were sufficient to decrease the rate of perceived exertion whereas eccentric power output increased (+40%). After training, maximal voluntary isometric contraction force measured during knee extension had significantly improved in all subjects, with a mean increase of 17%. Maximal cycling power was also significantly higher (+7%) after the training programme.

Conclusion

Taken together, these results show that moderate load eccentric bed cycling (i) was feasible and efficient, (ii) did not generate excessive individual perception of effort during exercise nor develop major muscular or joint pain after training and (iii) allowed early force and power gains in healthy subjects.

床上循环偏心训练的可行性和早期效果:潜在的临床应用

目的探讨中强度卧床偏心训练对健康个体的可行性及早期效果，探讨该训练模式是否可应用于卧床病人的日常护理。方法采用运动前干预措施进行纵向研究。一种适用于床的偏心测力器的开发允许在3周内对11名健康个体进行5次训练，强度不断增加。对训练前后的力-速度关系、膝关节最大自主伸直力和神经激活度进行评价。结果5次训练足以降低感知用力率，而偏心功率输出增加(+40%)。训练后，所有受试者在膝关节伸展时测量的最大自主等距收缩力均有显著改善，平均增加17%。训练计划后，最大循环功率也显著提高(+7%)。综上所述，这些结果表明，适度负荷的偏心床骑行(i)是可行和有效的，(ii)在运动过程中不会产生过度的个人努力感，也不会在训练后产生主要的肌肉或关节疼痛，(iii)允许健康受试者早期获得力量和力量。

期刊介绍： Clinical Physiology and Functional Imaging publishes reports on clinical and experimental research pertinent to human physiology in health and disease. The scope of the Journal is very broad, covering all aspects of the regulatory system in the cardiovascular, renal and pulmonary systems with special emphasis on methodological aspects. The focus for the journal is, however, work that has potential clinical relevance. The Journal also features review articles on recent front-line research within these fields of interest. Covered by the major abstracting services including Current Contents and Science Citation Index, Clinical Physiology and Functional Imaging plays an important role in providing effective and productive communication among clinical physiologists world-wide.
