Aim: Group-based training through Crossfit has recently exploded in popularity. When the effects of Crossfit trainings on many basic component are considered, the aim of this study is to investigate the effects of high-intensity functional trainings on anthropometric and physiological characteristics of sedentary individuals. Methods: Their age averages are 23.62±5.39 (year), height averages are 177±0.06 (cm) and body weight averages are 79.88±12.14 (kg). Crossfit training system was applied during highintensity functional exercise planning at four days a week, for twelve weeks. Body weight, body fat percentage, body mass index (BMI), blood pressure, resting heart rate, hand grip strength, back strength, leg strength measurements were taken from the participants. Statistical analyses were done with SPSS 15.00 statistical package program. Results: In pre-test and post-test measurements, it was found that there are statistically significant differences between the participants' body fat percentage, systolic blood pressure, diastolic blood pressure, left and right-hand grip, back strength and leg strength values (p<0.05). Conclusion: As a result, it can be said that these high-intensity exercises that were applied has positive contribution to anthropometric and physiological characteristics in sedanteries.

The aim of this study is to research the motivational factors affecting athletes to select the branches of athletics, ski and tennis. Within the scope of the research, the survey developed by H. Sunay in 1996 was implemented and solution for the problem of the research was searched through the findings that were obtained from the survey. SPSS survey program was used for the data obtained and by calculating Chi-square (X2) values, it was statistically tested whether the relation is significant. Alpha significance level was taken as (α = 0.05) in the tests conducted. At the end of the research, differences were detected between the opinions of female and male athletes in Agri regarding their expectations on the sport branch they deal with. Accordingly, environmental conditions, school sports halls and facilities, television broadcast and newspapers-journals of external motivational factors are seen to have low influences. It was detected that coaches, friend environment and physical education teachers have the first three ranks in reasons for athletes to choose their sport branches.

Objective Hepcidin may be an important mediator in exercise-induced iron deficiency. Despite the studies investigating acute exercise effects on hepcidin and markers of iron metabolism, we found no studies examining the chronic effects of walking exercises (WE) on hepcidin and markers of iron metabolism in premenopausal women. The chronic effects of two 8-week different-intensity WE on hepcidin, interleukin 6 (IL-6), and markers of iron metabolism in pre-menopausal women were examined. Methods Exercise groups (EG) [moderate tempo walking group (MTWG), n = 11; brisk walking group (BWG), n = 11] walked 3 days/week, starting from 30 to 51 min. Control group (CG; n = 8) did not perform any exercises. BWG walked at ∼70%-75%; MTWG at ∼50%-55% of HRR. VO, hepcidin, IL-6, and iron metabolism markers were determined before and after the intervention. Results VO increased in both EGs, favoring the BWG. Hepcidin increased in the BWG (p < 0.01) and CG (p < 0.05). IL-6 decreased in the BWG and the MTWG (p < 0.05; p < 0.01). While iron, ferritin, transferrin, and transferrin saturation levels did not change in any group, total iron binding capacity (p < 0.05), red blood cells (p < 0.05), and hematocrit (p < 0.01) increased only in the BWG. Conclusion Both WE types may be useful to prevent inflammation. However, brisk walking is advisable due to the positive changes in VO and some iron metabolism parameters, which may contribute to prevent iron deficiency. The increase in hepcidin levels remains unclear and necessitates further studies.

Introduction. The aim of the study was to examine the effect of circadian rhythm on dynamic balance performance and to determine the role of physical activity level, body temperature, chronotype, and gender in this possible effect. Material andmethods. Forty-two young male and female subjects with different physical activity levels participated in the study. A dynamic equilibrium test, a Star Excursion Balance Test (SEBT), was conducted at 9:00, 13:00, and 17:00 on three different days with at least two days of interval between tests. The test scores were calculated by dividing the reaching distances by the leg length and multiplying the quotient by 100. The physical activity level and sleep state were evaluated using questionnaires. Before each test, body temperatures were measured orally. Results. The best SEBT scores were found at 13:00 and 17:00 in the male group and in the trained group. The body temperature changes increased parallel to SEBT scores. The scores for the non-dominant leg were found to be significantly different in posterior test directions, and those for the dominant leg were different in anterior directions. Chronotype did not affect the test results. Conclusions. Circadian rhythm was found to have an effect on dynamic balance performance. Body temperature, gender, and physical activity level were also found to play a role in this effect.
