Abstract

Svrha: Glavni cilj ovoga istraživanja bio je utvrditi kako trajanje i kvaliteta sna utječu na subjektivni doživljaj napora kod aerobnog vježbanja. Metode: Sudionici istraživanja su odrasle osobe koje se bave rekreativnim trčanjem u klubu trčanja „Trčaona“. Uzeti su podaci 34 ispitanika od čega 20 žena te 14 muškaraca. Pokazatelji kvalitete i kvantitete sna mjereni su Fitbit Charge 3 mjeračima tjelesne aktivnosti kroz 14 uzastopnih dana i noći. Mjereni pokazatelji sna su: ukupno vrijeme spavanje, budnost nakon usnivanja, efikasnost sna i vrijeme provedeno u krevetu. Subjektivni doživljaj težine treninga ispitanici su ocjenjivali sukladno modificiranoj Borgovoj skali. U isto vrijeme intenzitet treninga bio je praćen pomoću frekvencije srca mjerene na zapešću putem Fitbit Charge 3 mjerača aktivnosti. Također je izračunata i razlika u rezultatima subjektivnog doživljaja težine treninga (procijenjeni doživljaj intenziteta, odnosno procijenjena frekvencija srca) i objektivnog pokazatelja (frekvencija srca mjerena na zapešću). Studentov T-test za zavisne uzorke se koristio za utvrđivanje statističke značajnosti razlika između osjećaja napora i objektivnog pokazatelja napora, ovisno o kvaliteti i trajanju sna. Multivarijantna linearna regresijska analiza korištena je kako bi se provjerilo li moguće predvidjeti vrijednost osjećaja napora i razlike između osjećaja napora i objektivnog pokazatelja napora na temelju više parametara sna uz koje su kovarijable bile dob i spol sudionika te trajanje treninga. Rezultati: Analiza je pokazala kako nijedan od parametara kvalitete i kvantitete sna nije bio povezan s osjećajem napora procijenjen modificiranom Borgovom skalom. Također, nijedan od parametara kvalitete i kvantitete sna nije bio povezan s razlikom subjektivnog osjećaja napora procijenjenog modificiranom Borgovom skalom i objektivnog pokazatelja opterećenja. U rezultatima isto tako nema uočenih statistički značajnih razlika između osjećaja napora i objektivnog pokazatelja napora treninga koji su se odvijali nakon dana odnosno noći u kojima su ispitanici imali maksimalne i minimalne vrijednosti pojedinog pokazatelja kvalitete ili kvantitete sna. Zaključak: Rezultati istraživanja ukazuju na to kako trajanje i kvaliteta sna nemaju statistički značajni utjecaj na subjektivni doživljaj napora kod aerobnog vježbanja rekreativnih vježbača s prethodnim iskustvom. Buduća istraživanja bi se trebala usmjeriti na dulje razdoblje praćenja ispitanika kao i na skupine ispitanika s poremećajima u spavanju.

Abstract (english)

Purpose: The aim of this study was to establish how does duration and quality of sleep influence subjective perceived exertion in aerobic training. Methods: Participants of this study were adults engaged in running and associated with running club „Trčaona“. Data was collected from 34 participants from which 20 are female and 14 are male participants. Indicators of quality and quantity of sleep were measured using Fitbit Charge 3 activity and sleep monitor for 14 consecutive days and nights. Measured indicators of sleep were: total sleep time, wake time after sleep onset, sleep efficiency and time in bed. Subjectively perceived exertion in training was graded by participants according to modified Borg scale. At the same time, intensity of training was monitored through Fitbit Charge 3 activity monitor and its wristband heart rate monitor. Also, difference between subjectively perceived exertion (subjectively estimated intensity/estimated heart rate) and objective indicator of effort (wristband measured heart rate). Student T-test for dependent samples was used for determining significance of statistical difference between subjective perceived exertion and objective indicator of effort, depending on quality and quantity of sleep. Multivariate linear regression analysis was used to determine if it is possible to predict the value of subjectively perceived exertion and objective indicator of effort based on multiple parameters of sleep and covariables – age and gender of participants and duration of training session. Results: Analysis showed that none of the parameters of quality and quantity of sleep were linked with subjectively perceived exertion estimated by modified Borg scale. Also, none of the parameters of quality and quantity of sleep were linked with difference between subjectively perceived exertion estimated by modified Borg scale and objective indicator of effort. Results also show that there are no statistically significant differences between subjectively perceived exertion and objective indicator of effort on the days, that is, nights in which participants measured maximal and minimum values of individual indicators of sleep quality or quantity. Conclusion: The results of the study indicate that the duration and quality of sleep do not have a statistically significant effect on the subjective experience of exertion in aerobic exercise of recreational exercisers with previous experience. Future research should focus on a longer follow-up period of subjects as well as on groups of subjects with sleep disorders.
