Acute Effects of YO-YO Intermittent Recovery Test Level 1 (YO-YOIR1) Performed In The Morning And Evening On Biochemical Parameters

Abstract

In the preŞent study, we investigated possible alterations biochemical parameters in response to Yo-Yo intermittent recovery test level 1 (Yo-YoIR1) which is currently used to assess endurance performance, in soccer players. Thirteen soccer player volunteers from Tavasbirlik Spor soccer team who played in the Denizli Super Amateur league participated voluntarily. Yo-YoIR1 test was applied to the athletes on two different days, morning and evening. Blood samples were collected before, during and immediately after test. During the test, the total distance was recorded. Lactate values were measured with blood from the earlobe. Glucose, triglyÇeride, VLDL, HDL, LDL, CK, AST, ACTH, Cortisol, T3, T4, TSH, GH, Total cholesterol, Insulin, C-Peptide measurements were made in biochemical measurements. As a result, a statistically significant difference was found between the morning and evening values biochemical parameters (p<0.05). There was a statistically significant difference between the total distance and blood lactate values in the morning and evening measurements (p<0.05). As a conclusion, it can be said that the endurance tests in soccer players are more effective in terms of performance in the evening hours.
