Styrketräning är ett effektivt sätt att trötta ut både kropp och hjärna för att förbättra sömnen, enligt en ny studie. Träning i allmänhet, men särskilt pass som innehåller styrkeövningar för att öka muskelstyrkan, kan vara till stor hjälp för äldre vuxna med sömnproblem.
Participants in the study were adults aged 60 years and older.

En studie i Kina som följde studenters fysiska aktivitet under sju dagar visade att de med insomni sov bättre de dagar de ägnade sig åt mer intensiv fysisk aktivitet eller var mer stillasittande än vanligt. Däremot försämrades deras sömn de dagar de utförde mer lätt fysisk aktivitet än vanligt. Ingen signifikant koppling mellan fysisk aktivitet och sömnkvalitet hittades hos studenter utan insomni.

Abstract
Objective
At the between-person level, it is well-documented that individuals with more physical activity (PA) and less sedentary behavior (SB) tend to have better sleep outcomes than their peers. However, the associations at the within-person level remain unclear. This study investigated the daily associations between PA and SB with nighttime sleep among young adults with and without insomnia symptoms.
Methods
Data was collected through activity trackers and online questionnaires for 7 consecutive days among 147 university students, including time spent on moderate to vigorous physical activity (MVPA), light physical activity (LPA), and SB, along with sleep duration, sleep efficiency, and sleep quality. Participants were classified into two subgroups according to the presence of insomnia symptoms, which were determined by a self-reported insomnia scale. Multilevel compositional data analysis was conducted on the total sample, and separately on subsamples characterized by the presence and absence of insomnia symptoms.
Results
In the total sample and subsample without insomnia symptoms, substitutions among MVPA, LPA, and SB were not associated with changes in sleep outcomes at the daily level. However, in the subsample with insomnia symptoms, days with more MVPA or SB and less LPA were associated with higher sleep efficiency, while days with more LPA at the expense of MVPA or SB were associated with lower sleep efficiency.
Conclusions
For young adults with insomnia symptoms, replacing LPA with MVPA on a given day may improve their sleep efficiency that night.
Broscience verkar vara den gällande sanningen för bodybuilding vilket visar sig när det görs studier kring det.
Nu är det bara att fylla på med protein kl 21, 01, 03 och 04 för att maximera muskeltillväxten.
