    The effect of exercise induced weight-loss on myokines and adipokines in overweight sedentary females: steps-aerobics vs. jogging-walking exercises
    (Edizioni Minerva Medica, 2018) Duzova, Halil; Gullu, Esin; Cicek, Guner; Koksal, Burcu K.; Kayhaayhan, Basak; Gullu, Abdullah; Sahin, Ibrahim
    BACKGROUND: The objectives of this study were to verify effects of step-aerobic exercise (SAE) and jogging-walking exercise (JWE) program on myokines and adipokines levels in overweight sedentary females. METHODS: Volunteer subjects (N.=25) were assigned to two exercise groups: steps aerobics and jogging-walking. The exercise program given to them was for five days a week and for twelve weeks period. Serum samples were collected from venous blood before and immediately after Cardio-Respiratory Fitness Test (CRF) by Bruce protocol and stored at -80 degrees C until they were assayed before 12 weeks exercise program. After 12-weeks training program this procedure was repeated. Serum TNF-alpha, IL-6, IL-15, IL-17, IL-18, leptin, resistin and adiponectin levels were assayed by ELISA. RESULTS: Leptin and IL-15 levels were increased whereas resistin levels were decreased after CRF Test in JWE training group following 12-weeks exercise program. TNF-alpha, IL-15 and IL-18 levels were higher and leptin levels were lower in SAE group than JWE group after 12-weeks exercise period. However, both SAE and JWE did not lead to significant change in serum levels of IL-17, IL-6 and adiponectin levels. CONCLUSIONS: This study has added to existing knowledge that both SAE and JWE may cause weight loss especially in fat mass. But, the effect of SAE and JWE on myokines and adipokines levels may be the different. Further studies are needed to find out clinical importance of these findings.

    The relationship between serum leptin and VO2max levels in pre-puberty swimmer girls: effect of acute exercise
    (Mattioli 1885, 2020) Gullu, Esin; Gullu, Abdullah; Duzova, Halil; Ozgor, Bilge; Kilinc, Evren; Akcinar, Faruk
    Objective: The aim of this study was to determine the relationship between serum leptin (SL) level, which is the sensor of changes in energy intake and consumption, and maximal oxygen consumption (VO2max) level in pre-puberty swimmer girls. Methods: Voluntary participants were divided into swimmer group (n:16) and the control group (n:15). Bruce protocol was used for acute exercise effect. Body composition, VO2max and SL concentrations of the study group were measured before and after acute exercise. The paired-samples t-test and independent samples t-test were used for intra- and inter-group comparisons. The linear relations between the VO2max and SL levels were determined by Pearson correlation coefficient. The level of significance was used at 0.05. Results: There was a significant difference between the SL level and test stage, test duration, HR of test-end, and VO2max variables in both groups (p<0.05). There was a high level of negative correlation between VO2max and SL levels in both groups after exercise (SG, r=-0.63; p<0.01, and CG, r=-0.60; p<0.05, respectively). Conclusion: Acute exercise resulted in decreased SL levels of both groups. It was concluded that regular swimming sports has a positive effect on body composition, VO2max, and SL values of pre-pubertal girls.
