Metode: Prikupljeni su podaci 18 prigodno odabranih mladih odraslih osoba (raspon dobi: 18-27), od čega 13 žena i 5 muškaraca. Proveden je randomizirani kontrolirani ukriženi pokus u kojem su ispitanici nasumično raspoređeni u AB/BA tretman. Tretman A označavao je provođenje vježbanja svaki drugi dan tijekom jutarnjih sati (do zaključno 14:00h), dok je tretman B uključivao vježbanje u večernjim satima (nakon 21:00h). Pokazatelji kvalitete i kvantitete sna mjereni su Fitbit Charge 3 mjeračima tjelesne aktivnosti (Google Fitbit, SAD) kroz 14 uzastopnih dana i noći. Mjereni pokazatelji sna bili su trajanje spavanja, budnost nakon usnivanja, efikasnost sna i trajanje dubokog sna. Subjektivna procjena kvalitete sna ispitivana je putem The Groningen Sleep Quality Scale, a raspoloženje ispitanika PANAS upitnikom. Studentov T-test za zavisne uzorke korišten je za utvrđivanje statističke značajnosti pojedinih parametara sna i raspoloženja u različitim periodima vježbanja koje se provodilo u dva ciklusa, do 14 sati i nakon 21 sat, te za usporedbu između dana s vježbanjem u odnosu na dane bez vježbanja. Rezultati: Analize su pokazale kako nijedan od parametara kvalitete i kvantitete sna nije bio značajno promijenjen pod utjecajem vježbanja. Nisu uočene značajne razlike u objektivnim parametrima kvalitete i kvantitete sna između dva ciklusa vježbanja kao niti u subjektivnoj procjeni kvalitete sna. Također, nije bilo značajnog utjecaja vježbanja na raspoloženje niti u jednom periodu pokusa. Zaključak: Glavni rezultati ovog istraživanja ne pokazuju direktnu povezanost vremena vježbanja na kvalitetu sna, kao ni tjelesne aktivnosti na raspoloženje. U budućim istraživanjima bilo bi potrebno produljiti vrijeme trajanja istraživanja i uzeti u obzir remeteće faktore uz maksimalnu mogućnost njihove kontrole.
Abstract (english) Purpose: The aim of this study was established how does exercise at different times of the day influence quality of sleep and mood. Methods: Data was collected from 18 young adults (age range: 18-27), 13 females and 5 males. A randomised crossover design was applied, and participants were randomly assigned to AB/BA treatment. Treatment A dictated exercise on every other day in the morning (until 2 p.m.), while during treatment B exercise was performed in the evening (after 9 p.m.). Indicators of quality and quantity of sleep were measured using Fitbit Charge 3 activity and sleep monitor (Google Fitbit, USA) throughout 14 consecutive days and nights. Parameters of sleep assessed in this study were total sleep time, wake time after sleep onset, sleep efficiency and duration of deep sleep. In, addition, subjective assessment of sleep quality was done every morning using The Groningen Sleep Quality Scale, while at the same time the PANAS questionnaire was used to evaluate the mood of the participants. Student T – test for dependent samples was applied for determining differences between individual parameters of sleep and mood in different treatment periods and to compare days with exercise versus days without exercise. Results: Analysis showed that none of the parameters of quality and quantity of sleep were significantly affected by the timing of exercise. There were no significant differences noticed in objective or subjective parameters of sleep quality and quantity between two cycles of exercises. Also, no significant effect of exercise on mood was recorded, in any of the exercise treatments. Conclusion: The results of this research show that there is no direct connection between exercise time and sleep quality, as well as connection between physical activity and mood. Future research should focus on extending the duration of the trial, and account for various sleep disruptors which should be controlled as much as possible.
