THERE ARE NO NON-RESPONDERS TO RESISTANCE EXERCISE IN OLDER MEN & WOMEN – 2015


DESIGN/SETTING/PARTICIPANTS
– 12 (n=110) and 24 (n=85) wks of resistance-type exercise training in older (>65 yrs) men and women
RESULTS
(1) Lean body mass increased from 0 to 12 wks of training
(2) From 0 to 24 wks, lean body mass increased
(3) Type I and II muscle fiber size increased
(3) From 0 to 24 wks, type I and II size increased
(4) The 1-RM strength on leg press and leg extension increased
(5) From 0 to 24 wks, leg press and leg extension 1-RM increased
(6) Chair-rise time decreased by 1.3 ± 0.4 seconds
(7) Nonresponsiveness was not apparent in any subject, as a positive adaptive response on at least one training outcome was apparent in every subject
CONCLUSIONS
(1) A large heterogeneity was apparent in the adaptive response to prolonged resistance-type exercise training when changes in lean body mass, muscle fiber size, strength, and physical function were assessed in older men and women
(2) The level of responsiveness was strongly affected by duration of exercise intervention, with more +ve responses following more prolonged exercise training
(3) There are no non-responders to the benefits of resistance-type exercise training on lean body mass, fiber size, strength, or function in the older population
