| ABSTRACT |
| The
purpose of this study was to investigate the effect of moderate strength
and endurance training on cognition evaluated by event-related potentials
(ERP) in older people. Thirty-six adults, aged 60-85 years, were randomly
divided into three groups: sedentary control (C), strength training
(ST), and endurance training (ET). Participants performed functional
fitness tests and ERP data were recorded before and after nine weeks
of training. Training involved three sessions per week. Functional
fitness test performance improved significantly in the ST and ET groups.
The latencies of the N1, N2, and P2 components and the amplitudes
of the N1P2, P2N2, and N2P3 components differed significantly between
groups (p < 0.05). After training, the latencies of the P2 and
N2 components at the Fz and Cz sites, decreased significantly, and
the amplitudes of the N1P2, P2N2, and N2P3 components at the Fz site
and the N1P2 and N2P3 components at the Cz site, increased significantly
in the ST group compared with the ET group. After training, the latencies
of N1, N2, and P2 components shortened significantly, and the amplitudes
of the N1P2, P2N2, and N2P3 components increased significantly in
the ST group compared with the C group. The latencies of the N2 and
P2 components shortened significantly in the ET group compared with
the C group, although the amplitudes of the ERP recordings did not
differ significantly between groups. These data suggest that strength
training might facilitate early sensory processing and cognitive functioning
in older individuals.
