Eksperimentalna skupina je bila podvrgnuta parcijalnoj deprivaciji sna. 2 dana zaredom je spavala 4 ili manje sati, dok je kontrolna skupina zadržala uobičajeni režim spavanja. Količina sna je praćena mobilnom aplikacijom Azumio te dnevnikom spavanja. Ispitanice su testirane u skoku bez pripreme, skoku s pripremom i raspoloženju, prije i nakon 2 dana parcijalne deprivacije sna. Na testiranje su dolazile uvijek u isto doba dana te su prije testiranja ispunile Wellness upitnik za procjenu raspoloženja. Zatim su provele standardizirani protokol zagrijavanja, nakon kojeg su testirane u skoku bez pripreme i skoku s pripremom. Utvrđena je statistički značajna razlika u raspoloženju i u skoku bez pripreme između eksperimentalne i kontrolne skupine u finalnom mjerenju te između inicijalnog i finalnog mjerenja u eksperimentalnoj skupini. U kontrolnoj skupini nije utvrđena razlika ni u jednoj promatranoj varijabli. Isto tako u kontrolnoj skupini ne postoje razlike ni u jednoj točki mjerenja. S obzirom na dobivene rezultate može se zaključiti da 2 dana parcijalne deprivacije sna negativno utječe na raspoloženje i izvedbu skoka bez pripreme, dok na skok s pripremom nema utjecaj. Prema tome, potrebno je poduzeti sve mjere kojima bi se smanjila redukcija sna i tako prevenirao pad u izvedbi i raspoloženju.
Abstract (english) The aim of this study was to investigate the effect of partial sleep deprivation on mood, squat jump (SJ) and countermovement jump (CMJ) performance. 23 physical education female students volunteered in the study and were randomly divided to experimental and control group. The experimental group was subjected to two days of partial sleep deprivation with less than 4 hours of sleep per night. The control group kept their habitual sleep habits. The amount of sleep was measured with the mobile application Azumio and with a sleep diary. The participants were tested in squat jump, countermovement jump and mood before, and after two days of the experimental procedure. The participants were always tested at the same time. First, they filled up a wellness questionnaire for the assessment of mood. After that, the participants performed a standardized warm-up protocol. After the warm-up protocol they were tested in the squat jump and in the countermovement jump. Statistical significant difference was found between the experimental and control groups after two days of partial sleep deprivation in mood and in squat jump performance. In addition, statistical significant difference was found between the initial and final measurement in mood and in the squat jump performance in the experimental group. No difference in either variable was found in the control group. The results indicate that partial sleep deprivation negatively affects mood and squat jump performance, with no effect on countermovement jump performance. In conclusion, it is important to use strategies that will reduce partial sleep deprivation and in that way prevent the negative effects on mood and performance.
