Study aim: This study examines the relationship between different magnitudes of asymmetry and their effects on speed performance. Material and methods: Forty-two sub-elite male youth soccer players performed a 30-m sprint, change of direction, single leg countermovement jump and single leg hop. Subjects were divided into groups with vertical and horizontal asymmetry, and both groups were then divided into three groups according to magnitudes of inter-limb asymmetry (<5%, 5–10%, and >10%). Results: The results showed no significant correlation between different jump asymmetry magnitudes and the mentioned outcomes of speed performance (p > 0.05). In addition, larger asymmetries resulted in faster linear speed, even if small differences (g range = 0.00 to 0.57; p > 0.05). But this was not similar for change of direction speed (g range = –0.42 to 0.34; p > 0.05). Conclusions: There are inconsistent findings for the effects of inter-limb asymmetries on speed performance. The results of the present study indicate that the magnitude of asymmetry had no meaningful association with independent measures of performance in soccer players. Therefore, it seems more likely to explain the effects of individual asymmetries on performance rather than the idea that asymmetry negatively affects performance.

Öz: Gerek sportif gerekse rekreatif etkinlik bakımından birçok fırsatlar sunan su ortamı; insanların doğal yaĢam alanı olmamakla beraber fiziksel yapı özellikleri itibariyle su üstünde batmadan durmayı sağlar. Suda boğulma genel tanımlama ile; sıvı bir ortam içerisinde batmadan/dalmadan kaynaklanan solunum bozulması ile giden süreçler dizisidir. Boğulma ciddi bir halk sağlığı problemidir. Kesin rakam belli olamamakla beraber; Türkiye"de her yıl bine yakın insan boğularak can vermektedir. Abstract: Drowning is defined as the process of experiencing respiratory impairment from submersion /immersion in a liquid. Drowning is a serious public health problem. Although the exact number cannot be determined, nearly 1000 people drown every year in Turkey. The aim of this study was to examine cases of accidental death by drowning in water in Gaziantep province between 2005 and 2016. News was searched online via search engines using keywords such as "drowning, drowned by falling in the water, rescuer drowning" etc. in this study. The news was collected day by day for the period between January 1st, 2005 and December 31st, 2016. Personal information concerning the victims, the place of drowning, the reasons for being there, water environment, the time of day, were recorded. Analysis of the data was performed using SPSS 18.0. As a result of this research it was found that 97 people had lost their lives in this 12 year period through drowning in the province of Gaziantep. Water safety training should be provided to children at an early age to prevent deaths by drowning, and safe swimming areas should be built around water resources.
