Exercise Addiction and Sleep Quality in Female Volleyball Athletes

Abstract

Uvod: Odbojka je ekipni sport gdje se natječu dvije ekipe, a svaku čini po šest igrača u terenu te izmjene. Specifičan je sport zbog samog načina igre i intenziteta te zahtjeva veliki broj tjelesnih vještina igrača zbog promjena tempa igre. Za vrijeme spavanja dolazi do integracije pamćenja i hormonalnih procesa. Smanjenja količina sna negativno utječe na lučenje hormona te se smanjuje sposobnost oporavka organizma. Kvalitetan san ima pozitivan učinak u početnim fazama učenja te dugoročnoj memoriji. Cilj: Utvrditi kvalitetu sna kod aktivnih odbojkašica te njihovu ovisnost o vježbanju. Metode: Za potrebe izrade završnog rada provedeno je istraživanje u obliku anketnog upitnika. U istraživanju je sudjelovalo 52 ispitanika, a uzorak čine sportašice u odbojci koje su u trenažnom i natjecateljskom procesu. Kriteriji uključenja uključuju odbojkašice koje još uvijek treniraju i natječu se, a kriteriji isključenja su odbojkaši te odbojkašice mlađe od 14 godina. Anketni upitnik sastoji se od socioekonomskih podataka, Skale ovisnosti o vježbanju, Skale pobuđenosti prije spavanja te Pittsburgh-ovog indeksa kvalitete spavanja. Rezultati: Istraživanje je uspoređeno s nekoliko drugih studija ovisnosti o vježbanju i kvalitete sna kod sportaša u odbojci te ostalim timskim i individualnim sportovima. Rezultati pokazuju da sportaši imaju uglavnom dobru kvalitetu sna iako imaju ovisnost o vježbanju. Kvalitetan san kod sportašica u odbojci važan je dio rasta i razvoja. Kako bi san bio što kvalitetniji važno je paziti da na dođe do pretreniranosti, psihološkog stresa te da spavaju onoliko koliko je potrebno za njihovu dob i funkcioniranje. Rezultati ovog istraživanja ukazuju na važnost kvalitete sna i povećanog rizika od ovisnosti o vježbanju.Introduction: Volleyball is a team sport in which two teams compete, each consisting of six players on the court plus substitutes. It is a unique sport due to the style of play and intensity, requiring a wide range of physical skills from players because of frequent changes in game tempo. During sleep, memory integration and hormonal processes occur. A reduced amount of sleep negatively affects hormone secretion and decreases the body’s ability to recover. Quality sleep has a positive impact on the early stages of learning and long-term memory. Objective: To determine quality of sleep in active volleyball players and their exercise addiction. Methods: For the purpose of this thesis, a survey-based research study was conducted. The study included 52 participants, all of whom are female volleyball players actively engaged in training and competitive processes. Inclusion criteria included currently training and competing female volleyball athletes, while exclusion criteria ruled out male players and female players under the age of 14. The questionnaire consisted of demographic and socioeconomic data, the Exercise Dependence Scale, the Pre-Sleep Arousal Scale, and the Pittsburgh Sleep Quality Index. Results: The findings were compared with several other studies related to exercise dependence and sleep quality in volleyball athletes as well as athletes from other team and individual sports. The results indicate that athletes generally have good sleep quality despite showing signs of exercise dependence. Quality sleep is an essential component of growth and development in female volleyball players. To maintain optimal sleep quality, it is important to avoid overtraining, manage psychological stress, and ensure they get the appropriate amount of sleep for their age and needs. The results of this study highlight the importance of sleep quality and the increased risk of exercise dependence
