    Effect of carbohydrate-electrolyte consumption on insulin, cortisol hormones and blood glucose after high-intensity exercise
    (Taylor & Francis Ltd, 2019) Mor, Ahmet; Kayacan, Yildirim; Ipekoglu, Gokhan; Arslanoglu, Erkal
    Objective: This study aimed to examine the effect of CHO-E consumption after high-intensity exercise on insulin, cortisol hormones and blood glucose responses, which is important for performance and recovery in athletes. Methods: Sixteen volunteers, male athletes, participated into this study. Athletes were divided into two groups as experiment (CHO-E) and placebo (PLA). Blood was taken from the athletes three times as basal, post-exercise (PE) and 2 h after ingestion of supplement (PS). Results: When inter-group comparisons, insulin was significantly higher in the CHO-E group than the PLA group at the PS phase (p < .05). Cortisol significantly decreased in the CHO-E group at the PS compared to the PE (p < .05). Conclusions: Carbohydrate-electrolyte consumption after high-intensity exercise, accelerates the recovery process by providing optimal recovery, and enable the metabolism to remain in the anabolic state by preventing it from entering in the catabolic process as well as provides hormonal balance in metabolism.

    Negative effect of extra voice stimuli and elimination of this effect using hypnotic suggestion
    (Editura Universitatii din Pitesti, 2016) Kaya, Yalçin; Kayacan, Yildirim; Mor, Ahmet; Kaya, Ahmet Selım
    This study is realised for testing ratro of the sportmen performances which is effected by stimuli organ’s (voice) negative acts and this effected which can be decreased or not by hypnatic suggestion is realised, also If it can be decreased; the kind of stimuli and the ratio of it must be researched. This study is applied to 28 volunteer subject who were national. Before hypnosis, force application is measured with TMR EST 1000 isometric muscle training measuring equipment. During force applying, to quinea-pigs 80, 100, 110 and 120 decibels voice 1000 Hz (cih-diagmostic audiometer AS 67 (equal intensity to the ear), applied to stimuli is determined. At the second part of the study, hypnosis is applied to the same guinea-pigs and stimuli are mentioned to them. Standart suggestions were give and said tahat; when they percieved stimuli, applied forces could be increased, felt more energetic and strang. Same stimuli were applied again at the same units. Both isometric strength difference between the state and the Wilcoxon Signed Ranks Chi-Square test were analyzed using statistical method. Results were compared. In conclusion; value variation between “before hypnosis” and “after suggestion”, “during hypnosis” and “after hypnosis” were evaluated statistical. Consquently, when visual caution is given and maximum affect level is reched; at statistical there are meanful difference between hypnosis applied and not applied conditions, at auditory stimuli (80 db; p<0,001, 100 db; p<0,001, 110 db; p<0,001, 120 db; p<0,001). As a result; from this foundations and abtained findings; sportsmen concentrations are deranged by extre stimuli (it presants differenty from person to person and also different ratio), but this negative effects will be remoued by hypnotic suggestions. We must think of its curative sides of Europe, World an Olympiad medals’s color and owner this subject must be taken seriously and taken into consideration. © JPES.

    Psychophysiological stress regulation in football athletes during competition
    (Edizioni Minerva Medica, 2017) Kayacan, Yildirim; Mor, Ahmet; Ozgocer, Tuba; Ucar, Cihat; Yildiz, Sedat
    BACKGROUND: Exercise brings about endocrinological changes to balance homeostasis during challenging coordinative movements, thus leading to physiological and psychological stress. The present study aimed to assess, by non-invasive means, the stress levels and cortisol awakening responses (CAR) of athletes playing a football match. METHODS: Male football (soccer) players (N.=14, age 21.3 +/- 3.25 years) in a regional professional league took part in the study. To determine cortisol responses, saliva samples were taken on 3 different days during a regular league match. The salivary cortisol levels of the athletes were analyzed by ELISA. All participants were asked to fill in STAI-T questionnaires. The repeated measures test was used for cortisol comparisons between the sampling times and for CAR comparisons between days. RESULTS: According to the analyses, CAR levels decreased on the game day and increased the day after. As the competition time approached, the values beginned to rise but returned to initial values half time. At the end of the match, a slight increase was observed. There were no statistically significant differences in CAR and competition samples. There were no correlations between cortisol parameters and STAI-T scores (P>0.05). CONCLUSIONS: Football is a team sport requiring coordinated team effort and this appeared to incluence current data. Moreover, significant hormonal fluctuations related to competition revealed that professional football players are well adapted to the competition releated stress.
