The brain electrophysiological component P3, associated with good cognitive abilities, deteriorates during healthy aging. Both cognitive functions and P3 component amplitude respond positively to exercise, but the effects of resistance training on P3 are much less studied. Short-term resistance training interventions in older adults indicate modulation towards larger P3 amplitude, but this association has not been studied with a longitudinal study design. We investigated magnetoencephalographically recorded P3 (P3m) in a unique study design of nine aged men (mean age 77.7 y) with quasi-supervised resistance training background over a 10-year period and eight controls of similar age (mean age 77.5 y) with no training background. We elicited P3m utilizing lower limb electrical stimulation, as the resistance training program was mostly directed to lower limbs. Somatosensory oddball paradigm was performed with the right foot's fourth toe as standard (90%) and hallux as deviant (10%). Participants were asked to respond to deviants with a button press using their left index finger. Topographic maps showed bilateral temporoparietal activation for P3m in both groups. No amplitude differences were found in active P3m regions between groups. However, the groups differed in hemispheric activity of P3m. The exercise group showed stronger activation in the right frontotemporal and parietal sensor-groups compared to the left sensor-groups, and the control group showed stronger activation in right frontotemporal sensor-group compared to left. The control group showed shorter P3m latency in the right temporal sensor-group than the exercise group, but the latencies in other sensor-groups were similar. In aging, the brain utilizes compensatory areas to perform cognitive tasks. Our results suggest modulation in topographic distribution of P3m activity in aging men with long-term resistance training background compared to their controls. This might arise from a difference in age-related compensatory mechanisms in P3m generation. ...

Evidence of resistance training-induced neural adaptation in older adults Walker, Simon (Elsevier, 2021)The deleterious effects of aging on force production are observable from the age of 40 upwards, depending on the measure. Neural mechanisms contributing to maximum force production and rate of force development have been ...
Motivational characteristics and resistance training in older adults : A randomized controlled trial and 1-year follow-up Kekäläinen, Tiia; Kokko, Katja; Tammelin, Tuija; Sipilä, Sarianna; Walker, Simon (Wiley-Blackwell Publishing Ltd., 2018)The aim of this study was to investigate the effects of a 9‐month supervised resistance training intervention on motivational and volitional characteristics related to exercise, and whether the absolute level and/or ...
Regular strength and sprint training counteracts bone aging : a 10‐year follow‐up in male masters athletes Suominen, Tuuli H.; Alén, Markku; Törmäkangas, Timo; Degens, Hans; Rittweger, Jörn; Heinonen, Ari; Suominen, Harri; Korhonen, Marko T. (Wiley-Blackwell, 2021)Cross‐sectional and interventional studies suggest that high‐intensity strength and impact‐type training provide a powerful osteogenic stimulus even in old age. However, longitudinal evidence on the ability of high‐intensity ...
Corticospinal adaptations to strength training and its associations to rate of force development Enroth, Miro (2022)Introduction. Neuromuscular determinants underlying rate of force development during rapid muscle contractions may be more relevant compared to maximal strength in many athletic events characterized by power and speed, as ...
An age-adapted plyometric exercise program improves dynamic strength, jump performance and functional capacity in older men either similarly or more than traditional resistance training Van Roie, Evelien; Walker, Simon; Van Driessche, Stijn; Delabastita, Tijs; Vanwanseele, Benedicte; Delecluse, Christophe (Public Library of Science (PLoS), 2020)Power declines at a greater rate during ageing and is more relevant for functional deterioration than either loss of maximum strength or muscle mass. Human movement typically consists of stretch-shortening cycle action. ...
