    Effect of 12 Week Neuromuscular Weighted Rope Jump Training on Lower Extremity Reaction Time
    (Selçuk Üniversitesi, 2018 Ağustos) İpekoğlu, Gökhan; Suveren Erdoğan, Ceren; Er, Fatmanur; Baltacı, Gül; Çolakoğlu, Fatma Filiz
    The purposes of this study were to determine the influence of a jumping training protocol, using the weighted rope, on lower extremity visual and auditory reaction time performance in adolescent taekwondo (TKD) athletes. Twenty-two elite taekwondo athletes were randomly divided into two groups: the weigthed rope-trained (WRT) group (n = 11) and the control group (n = 11). Subjects in WRT group had jumping training 3 times a week for 12 weeks in addition to the routine taekwondo training program. The control group had no any training protocol in addition to the routine taekwondo training program. The visual and auditory reaction time performances of the subjects, both dominant and non-dominant legs were assessed with the Optojump System. The results of Paired Simple T test showed that the WRT decreased both the visual and the audiotory reaction time of non-dominant leg from pre to post-training (p=0.00, p=0.01 respectively). Although the pre-training audiotory and visual reaction times of dominant were similar between the groups (p>0.05), the post-training visual reaction time of dominant leg was significantly lower in the WRT group compared to control group (p=0.01). This study demonstrates that the weighted rope training program is effective in decreasing the reaction time in dominant and non-dominant leg. It is suggested that the WRT can be applied as an effective exercise program for enhancing visual and auditory reaction time performance.

    IL-6 and IL-1 beta responses to a carbohydrate-electrolyte drink in orienteering athletes
    (GDANSK UNIV PHYSICAL EDUCATION & SPORT, 2018) Ipekoglu, Gokhan; Gonulates, Suleyman; Er, Fatmanur; Yaman, Metin; Karacan, Selma; Cayci, Banu; Colakoglu, Filiz
    Background: This study was conducted to determine acute effects of carbohydrate-electrolyte (CHO-E) found in sports drinks, ingested just before an orienteering competition, on the levels of plasma IL-6 and IL-1 beta cytokine. Material and methods: The study was conducted in a randomized, double-blind design, including 23 elite orienteering athletes who volunteered to participate. Following the collection of resting specimens of blood, the experimental group (n = 12) was administered a sports drink containing CHO-E, while the placebo group (n = 11) was administered 500 ml of plain water. The subjects were asked to finish the orienteering competition. Result: IL-1 beta level in the 24th hour after the competition was found to be significantly lower than in precompetition and 2 hours after the competition in the placebo group (p < 0.05). The IL-6 levels of the experimental group in the 24th hour after the competition were significantly lower than those measured at the end of the competition and in the 2nd hour following the competition (p < 0.05). In intergroup comparisons, no significant differences were detected in the IL-1 beta and IL-6 levels (p > 0.05). Conclusion: A drink containing CHO-E might have stopped muscle contraction-associated cytokine production by increasing the tissue stability of the muscles, compensating the loss of fluid and electrolytes from athletes' bodies.

    Lean Body Mass as a Predictive Value of Hypertension in Young Adults, in Ankara, Turkey
    (IRANIAN SCIENTIFIC SOCIETY MEDICAL ENTOMOLOGY, 2015) Vaziri, Yashar; Bulduk, Sidika; Shadman, Zhaleh; Bulduk, Emre Ozgur; Hedayati, Mehdi; Koc, Haluk; Er, Fatmanur
    Background: The aim of this study was to assess the predictive capacity of body composition estimated by bioelectrical impedance analysis (BIA) to identify abnormal blood pressure in physical education and sport teaching students in the city of Ankara. Methods: Data for this cross-sectional study were obtained in the city of Ankara in 2014. A total of 133 students aged 20-35 yr participated in this study. Anthropometric measurements were measured. Body composition was assessed by BIA. Physical activity level (PAL) and usual dietary intake were assessed. Pre-hypertension and hypertension were defined, respectively, as BP >= 120 and/or 80, and >= 140 and /or 90 mmHg. Results: More overweight students showed abnormal BP especially SBP (P=0.005 and 0.002, respectively). Age adjusted regression showed significant association between arm circumference (beta= 0.176, P 0.044), mid arm muscle circumference (MAMC) (beta= 0.235, P 0.007), lean body mass (LBM) (beta= 0.238, P 0.006), basal metabolism rate (BMR) (beta= 0.219, P 0.012) and SBP and, also, MAMC (beta= 0.201, P 0.022), LBM (beta= 0.203, P 0.021), BMR (beta= 0.189, P 0.030) and DBP. Fat intake was associated with DBP (beta= 0.14, P = 0.040). Multivariate regression models adjusted for age, BMI, WC and fat intake/kg body weight showed positive association of SBP with MAMC, BMR and LBM (P<0.05). Conclusion: The relationship between blood pressure and body composition in young adults may be associated to LBM and MAMC. LBM or MAMC in this population may be indirect indicators of heart muscle mass and heart pumping power.
