The impact of sleeping hours on some physical fitness components of military sports coaches in the Royal Air Force of Oman
The purpose of this study were to investigate the effect of the sleeping hours, short sleep vs normal sleep and to compare between acute effect vs chronic effect on a selected fitness components of military sports coaches. Ten military sports coaches from the Royal Air Force of Oman have been participated in this experimental method, where the application of experience was administered in 4 days. Each day the selected physical fitness components were measured in the morning and the evening period after 7 hours of sleep a night on the first day, while measurements were repeated after (4) hours of sleep a night on the second day, third, fourth, respectively. An Ektograph tool was used to determine the sleeping hours. Data were entered a Statistical Package for Social Sciences program. T test between four days, ANOVA and post hoc test Scheffe were used. Results were as follows:
- Significant differences in the first day and the second, third and fourth in the selected fitness components except of the strength and removal and installation of arms in favor of the first day.
- Significant difference in accuracy component where affected fourth
day negatively. Using (LSD), it appears that the value of equal to (17.5) and which turned out to be the biggest significant difference was in the fourth day, insured that the largest difference was in the fourth day.
- It was concluded that short sleep curtailment as an acute effect was less than that of short sleep curtailment as a chronic effect.
There were also derived suggestions based on this study results.
