    (Univ Ljubljana, Fac Sport, 2019) Sahin, Gulsah; Koc, Hurmuz; Baydemir, Baris; Abanoz, Hasan; Coskun, Ali; Gunar, Bilgetekin Burak
    The aim of this research was to examine the differences in agility, flexibility, aerobic capacity, vertical jump and vertical anaerobic power according to age and sex in children and young fencers. 76 children and young fencing athletes from 9-17 years (girl:30 and boy:46) who camped in Dardanos campus of Canakkale Onsekiz Mart University participated in the research. The measurements and tests were conducted by the Sports Science and Athlete Health Research and Application Center. Length and weight measurements, BMI calculation, T-test for agility, Yo-Yo IR1 test and shuttle running test for aerobic capacity, maxVO(2) calculation equations, vertical jump test, anaerobic vertical power calculation, sit and reach test for flexibility were used in the study. ANOVA to determine the difference between age groups, t test for gender comparison was used. The level of significance was accepted as p < 0,05. As a result of the research, maxVO(2), elasticity, vertical jump and anaerobic vertical power parameters were found significant different between age groups (p<0,05). Accordingly, it was found that the flexibility of girls was significantly higher than boys (p<0,05). However, there was no found significant difference between girls and boys in VO(2)max, vertical jump, anaerobic vertical power and T test parameters (p>0,05). Vertical jump distance, vertical power, maxVO(2), and agility are similar in boys and girls. Flexibility in girls is better than boys. Differences in performance can be seen among age groups.

    Effect of high-intensity interval training vs. moderate-intensity continuous training in young trained cyclists
    (Editura Universitatii din Pitesti, 2022) Yalcin, Ebru; Sahin, Gulsah; Coskun, Ali; Yalcin, Onur
    Purpose: The aim of this study was to determine the effect of high intensity interval training (HIIT) vs moderate-intensity continuous training (MICT) on VO2max and anaerobic power in trained young cyclists in short period. Methods: Eighteen cyclists (between 15 and 20 years, n= 7 women, n= 11 men) were included in this study (age:17.50 years, height: 173.22 cm, body mass: 63.38 kg and body-mass index: 20.95 kg/m2). The cyclists were randomly divided into two groups. The training group (GHIIT, n= 9) participated in high intensity interval training two times per week for 6 weeks, while the Control Group (GCON, n= 9) completed moderate intensity continuous training (MICT). The training’ HR was conducted at 80%-95% HRmax for the first four weeks. In the last two weeks, the training’ HR was increased to %100 HRmax. The height, body mass, body fat %, aerobic and anaerobic power were measured. The maximal oxygen consumption (VO2max) was measured using a portable metabolic analyzer and, the traditional VO2max test followed a standard incremental design. Anaerobic capacity was evaluated by Wingate Anaerobic Test (WAnT) in 30sec. Results: There was no significant difference in body fat %, body mass, BMI, powerpeak, powermean, and powermin between GHIIT and GCON at the end of the training program (p>0.05). However, there was a significant difference in VO2max (p= 0.001) between GHIIT and GCON at the end of training (p<0.05). Conclusion: The high intensity interval training occurred a significant increase in VO2max. Anaerobic power improved but this result was not significant. Nevertheless, HIIT may use to improve in VO2max in young trained cyclists in short period. © JPES.

    Longitudinal Changes in Functional Fitness in Older Adults
    (Routledge Journals, Taylor & Francis Ltd, 2020) Sahin, Gulsah; Coskun, Ali; Apaydin, Serap
    Just as increases occurring in performance during the physical exercise period continue to be a topic of research, how long elderly individuals preserve these increases are also researched. The aim of this research is to investigate changes occurring in physical fitness of older adults in the exercise, detraining and retraining periods. The first period of the research included 15 elderly individuals (11 female, 4 male) with mean age 70.5 +/- 4.35 15 years, 163 +/- 11 cm height, and 68.5 +/- 10.8 kg. In the second period, 13 older adults (9 female, 4 male) participated with mean age 70.1 +/- 3.28 years, 161 +/- 0.08 cm height and 78.8 +/- 10.9 kg. Older adults participated in regular multicomponent exercise 2 days per week. The Senior Fitness Test (SFT) battery for older adults was used to assess functional fitness. Exercises were completed for 6 months and then there was a break of 5 months. The detraining effect was investigated. Five months later the second exercise period continued for 6 months. A multivariate analysis of variance (ANOVA) was used to identify significant differences between the first year and second year. There were significant differences in the physical fitness parameters of leg strength.

    THE ASSESSMENT METHODS OF PHYSICAL ACTIVITY LEVEL IN ELDERLY
    (Gunes Kitabevi Ltd Sti, 2011) Sahin, Gulsah
    Physical activity is powerful medicine that can change lives. An effective exercise prescription can improve strength, endurance, balance, function and quality of life. Physical activity epidemiological studies provide one of many types of research evidence that are necessary to assess the importance of physical activity to health. But, the assessment of physical activity level is very difficult and complex in elderly people. The major factors are culture, gender, age, disorders, motivation and cognitive function in elderly people for the assessment of physical activity level. There are two methods in order to assessment of physical activity level in elderly. Direct and indirect calorymetry, double labeled water, labeled bicarbonate and gas exchange. Indirect methods: The Ouestionnaire, heart rate, pedometer, accelerometer and physical activity index.

    The Importance of Physical Activity Level and Exercise Characteristics on Sleep Quality in Older Adults
    (Routledge Journals, Taylor & Francis Ltd, 2018) Sahin, Gulsah
    The aim of this study was to investigate the effects of exercise characteristics and physical activity level on sleep quality in older adults. The study was completed on 349 older adults. Individuals, aged 60 years and older who scored 24 or greater on the mini mental test's scores and who were not actively working were included. The short form of The International Physical Activity Questionnaire was used to determine the level of physical activity. The Pittsburgh Sleep Quality Index was used to evaluate sleep quality. There was a poor positive correlation between age and self-reported sleep quality in older women and older men (r = .205, p = .004, r = .317, p = .001). There was a negative correlation between physical activity and self-reported sleep quality in older women and older men (r = -.410, p = .001, r = -.488, p = .001). Living status was a factor significantly affecting sleep quality in older women (p = .016), whereas it was not significant for older men(p = .128). The presence of disease and regular exercise significantly affected sleep quality in older women and older men (p = .012, p = .003). However, no difference was found between exercise frequency, exercise duration, exercise time, exercise intensity and sleep quality in older adults (p > .05). According to these findings, regular exercise or physical activity at a minimal level may positively affect self-reported sleep quality in older adults. But exercise's characteristic does not affect self-reported sleep quality differently.

    Two different strength training and untrained period effects in children
    (2014) Coskun, Ali; Sahin, Gulsah
    The purpose of this study was to investigate effects of different strength training in trained period and untrained period. Thirty children (1st group weight mean: 30.50 ± 7.04 kg; height mean: 128.65 ± 6.74 cm; BMI: 18.06 ± 2.80 83 kg/m2 and 2nd group weight mean: 28.78 ± 4.50 kg; height mean: 131.12 ± 2.80 cm; BMI: 17.11 ± 2.83 kg/m2) participated to this study. Strength training was applied for 6 weeks. The children were divided to two groups as elastic band group and body weight training group. Height and weight measurements, leg strength test, sit-up test and push-up test were used in the study. All the tests were applied five times. Paired t- test, one Way ANOVA and repeated ANOVA statistics tests were used to analyze the data. The study results show that there were significant differences in leg strength and repetition of push-up between trained with elastic bands group and body weight after training group (p<0.05). There was no significant difference between sit-up (p>0.05). The time-dependent significant differences were found in push-ups, leg strength and sit-up (p<0.05). © JPES.
