Abstract EN
The rapid advancement of electromyography (EMG) technology facilitates measurement of muscle activity outside the laboratory during daily life.
The purpose of this study was to determine whether bursts in EMG recorded over a typical 8-hour day differed between young and old males and females.
Muscle activity was recorded from biceps brachii, triceps brachii, vastus lateralis, and biceps femoris of 16 young and 15 old adults using portable surface EMG.
Old muscles were active 16–27% of the time compared to 5–9% in young muscles.
The number of bursts was greater in old than young adults and in females compared to males.
Burst percentage and mean amplitude were greater in the flexor muscles compared with the extensor muscles.
The greater burst activity in old adults coupled with the unique activity patterns across muscles in males and females provides further understanding of how changes in neuromuscular activity effects age-related functional decline between the sexes.
