Resumo
Patients with chronic kidney disease on hemodialysis treatment have significant decrease on
muscle mass and function. These reductions are associated with greater mortality risk. Strength
training is a viable strategy to attenuate or even revert muscle wasting and loss of strength on this
population. Objective: To evaluate the effect of two distinct intradialytic resistance training on
muscle mass and functional capacity in hemodialysis patients. Methods: This is a 12-week
randomized, three-parallel-group, clinical trial that enrolled fifty participants (age 54.6 ± 11.6)
divided into three groups: hypertrophy group (GH, n=14) that performed a high intensity
intradialytic resistance training routine; muscle endurance group (GRM, n=16) that performed a
moderate intensity intradialytic resistance training routine; and control group (GC, n=20) that
performed a stretching routine. The exercises were offered three times a week during the
hemodialysis session. Body composition measurements were assessed by dual X-ray
absorptiometry (DEXA), and functional capacity was assessed by the Short Physical Performance
Battery score (SPPB)at baseline and after 12 weeks. Results: Appendicular muscle mass (p=0.007)
and functional capacity (p=0.002) increased in GH and GRM groups, and decreased in GC.
Nevertheless, only GH increased lean mass in the lower limbs (p=0.03). Perceived exercise
exertion and exercise adhesion to the protocols were similar in both groups. Conclusion: High
intensity intradialytic resistance training is associated to greater hypertrophy in hemodialysis
patients. However, physical training was associated to functional capacity and appendicular muscle
mass, independently of intensity.
