Effect of lighting conditions on fine hand motor skills in sleep deprived soldiers

Title: Effect of lighting conditions on fine hand motor skills in sleep deprived soldiers Objectives: Determination of the effect of sleep deprivation performed during blue light exposure and during blue light blocking on fine motor skills of the hands. Methods: This theoretical-empirical work was conducted on a research cohort of 8 young men (n = 8) with an average age of 22,6 ± 1.6 years, height of 181,1 ± 3,7 cm and weight of 76,9 ± 4,9 kg. The participants were volunteers from the Military Physical Education Department at the Faculty of Physical Education and Sport (FPE) of Charles University (UK). The participants were induced into total sleep deprivation for 36 hours in two interventions. During this time, they followed established rules to avoid bias in the results and the course of the intervention was conducted according to standardized conditions. The first sleep deprivation intervention was performed in light and the second in darkness with blue light blocking. Disassembly and machine gun collection took place at fixed times and conditions, always at 7:30 am and 7:30 pm. Before each measurement, probands completed the Epworth Sleepiness Scale (ESS) questionnaire, which monitored the subjective level of sleepiness. In total, four measurements were taken with sleep deprivation and one...Název: Efekt světelných podmínek na jemnou motoriku rukou u spánkově deprivovaných vojáků Cíle: Zjištění vlivu spánkové deprivace provedené při působení modrého světla a při blokování modrého světla na jemnou motoriku rukou. Metody: Tato teoreticko-empirická práce byla provedena na výzkumném souboru 8 mladých mužů (n = 8) s průměrným věkem 22,6 ± 1,6 let, výškou 181,1 ± 3,7 cm a hmotností 76,9 ± 4,9 kg. Účastníci byli dobrovolníci z oboru Vojenské tělovýchovy při Fakultě tělesné výchovy a sportu (VO FTVS) Univerzity Karlovy (UK). Účastníkům byla navozena totální spánková deprivace v délce 36 hodin ve dvou intervencích. Po tuto dobu dodržovali stanovená pravidla, aby nedošlo ke zkreslení výsledků a průběh intervence probíhal dle standardizovaných podmínek. První intervence spánkovou deprivací proběhla za světla a druhá za tmy s blokováním modrého světla. Rozborka a sborka samopalu probíhala v stálých časech a podmínkách, vždy v 7:30 hodin ráno a 19:30 hodin večer. Před každým měřením vyplňovali probandi dotazník (ESS) Epworthská škála spavosti, která monitorovala subjektivní míru spavosti. Celkem byla provedena čtyři měření s odepřením spánku a jedno měření bylo provedeno po 8hodinovém ozdravném spánku. Celkem bylo provedeno pět měření v intervenci za světla a pět za tmy, pokaždé dle stejného...Vojenská tělovýchovaFaculty of Physical Education and SportFakulta tělesné výchovy a sport

Effect of sleep deprivation on fine hand motor skills during disassembly and assembly of submachine gun Sa vz. 58

Title: Effect of sleep deprivation on fine hand motor skills, during disassembly and assembly of submachine gun Sa vz. 58 Objectives: Detection of the effect of acute sleep deprivation on the remediable motor skills of the hands. Methods: This theoretical-empirical work was performed on a research group of 14 young men (n=14) with a mean age of 23.1 ± 2.0 years, a height of 182.5 ± 5.8 cm and a weight of 79.7 ± 7.2 kg. These participants were volunteers from the field of military physical education at the Faculty of Physical Education and Sport (VO FTVS) of Charles University (UK). Participants were induced with acute (complete) sleep deprivation lasting 36 hours. During this period, they followed the set rules so that the results were not distorted and the course of the intervention proceeded according to standardized conditions. Disassembly and assembly of the submachine gun took place in relatively constant times and conditions, always in the morning and in the evening. The obtained data were then statistically processed in the program IBM SPSS ver. 25 using analyzes of variance of repeated measures. Results: The effect of sleep deprivation on fine motor skills of the hands was not evaluated statistically significant, it reached (p=0.398) in the analysis and (p=0.225) in the assembly of the..
