Acute Physiological Effects of Small-Sided Games Applied on the Hearing-Impaired National Team Soccer

The purpose of this study is to determine whether there is a difference between physiological responses to the small-sided games often applied during soccer trainings by changing the dimensions of the fields, the number of players, duration and the rules of the games. 16 sports people, who play soccer in Turkey Hearing- Impaired National soccer Team, having 31, 38±6,02 of age, 177,13±4,38 cms of height, 74,22±4,44 kgs of bodily weight, volunteered for this research.  The subjects were made to play free games with the intervals of 2 days, in different periods of 4x4, in the fields of 36mx24m, in 24 minutes in total in the forms of 1x24, 2x12, 4x6 and 6x4. After each game, a rest period of two days, and between the sets, a rest period of 4 minutes was given. Through anthropometric measurements of the subjects, their lactic acid levels in blood and the number of heart beats after small-sided games were determined. Also the difficulty levels perceived were determined with BORG scale. The data were transferred to IBM SPSS statistics 22 program and the analyses were completed. Friedman test was used to have a look whether there was a difference between descriptive statistics and dependent groups for continuous variables.At the end of the small-sided games applied in different periods and repetitions, a statistical meaningfulness was determined in the comparison of the speed of the heartbeat of the subjects that participated in the study(P<0.001). While a meaningfulness was determined in the comparison of the lactic acid amounts that appeared in the subjects (P<0.01); there was no statistical meaningfulness in the comparison of the perceived difficulty level of the small-sided games played.
