Age and controlled force exertion in Japanese women as measured by a computer-generated sinusoidal and quasirandom waveform display

摘要

This study examined the relationship between age and controlled force exertion in 215 right-handed Japanese women aged 20 to 84 years, as measured in sinusoidal and quasirandom waveforms tasks.The participants were divided into three groups based on age: 64 in the young group, 91 in the middle-aged group, and 60 in the elderly group. The participants adjusted their submaximal grip to the changing demand values, which were displayed as a sinusoidal or a quasirandom waveform on a computer screen. They performed the test three times. The evaluation parameters were the total differences between the demand values and grip exertion values.
