Abstract

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.
