Summary This study aims to investigate large muscle group movements (LMM) during sleep across the lifespan, from school‐aged children older adults, and examine their relationship with architecture (REM NREM). A total of 141 healthy participants were included, divided into five age groups: ( n = 43), adolescents 31), young adults 27), 16), 24). Polysomnography (PSG) was used record data LMM, along LMM associated arousals (LMMA) awakenings (LMMW), scored according recently established criteria. The indices durations analysed for each group, statistical comparisons made between groups REM NREM sleep. significantly increased age, exhibiting highest frequency LMMA, LMMW. duration longer in younger shorter adults. Significant differences patterns observed, particularly where LMMA more prevalent No significant sex found groups. showed clear age‐related trends, increasing decreasing advancing age. These are reflecting fragmentation instability. findings provide important normative lifespan demonstrate that sleep‐related motor activity is closely linked changes architecture.
