Long-term effects of a 6-week power-based resistance training and fast walking interval training program on physical function, muscle power, disability and frailty in pre-frail and frail older adults.
INTRODUCTION
Concurrent training has been shown to be a beneficial approach to improve overall health status in older adults. However, little is known about the adaptations of this type of training in the long term (i.e., after cessation of exercise), even less in older people affected by frailty syndrome.Therefore, this study aimed i) to assess the effects of a 6-week concurrent training program composed of power-oriented resistance training (RT) and fast walking interval training (FWIT) on physical function, muscle power, disability in activities of daily living and frailty in pre-frail and frail older people, and ii) to assess the effects of a 6-month detraining period on these outcomes.
METHODS
A total of 59 pre-frail and frail older adults (>75 years old; Frailty Phenotype >1) were allocated into intervention (INT; n=32; 81.8 years; 21 women) or control (CON; n=27; 82.5 years; 19 women) groups. Primary outcomes of this study were Short Physical Performance Battery (SPPB), relative sit-to-stand (STS) power, Barthel index, Lawton scale and Frailty Phenotype. Assessments were performed at baseline (PRE), after the concurrent training programme (POST) and after 6 months of follow-up (DET) in both groups. Mixed model repeated measures ANOVA with Bonferroni's post hoc tests was used.
RESULTS
Immediately after the intervention (∆= POST-PRE), INT improved SPPB (∆=3.0 points; p<0.001), relative STS power (∆=0.87 W·kg-1; p<0.001) and reduced their frailty levels (∆=-1.42 criteria; p<0.001), while no changes were observed in CON. After 6 months of detraining (∆= DET-PRE), INT showed higher SPPB (∆=2.2 points; p<0.001), higher relative STS power (∆=0.73 W·kg-1; p<0.001) and lower frailty (∆=-1.24 criteria; p<0.001) values than those reported at baseline, which were significantly different than those reported by CON. Both, Barthel index and Lawton scale values were not modified during the study in either group.
CONCLUSIONS
The 6-week concurrent training program improved physical function, muscle power and reduced frailty in pre-frail and frail older people and these improvements were maintained above baseline levels after 6 months of detraining. However, due to the individual variability found, future studies of long-term responders vs. non-responders in frail populations are required.
期刊介绍:
In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
