    THE ACUTE EFFECT OF COMBINED PRECONDITIONING STRATEGIES ON ANAEROBIC PERFORMANCE AND PHYSIOLOGICAL PARAMETERS IN AMATEUR SOCCER PLAYERS
    (2019) Yilmaz, Atakan; 0000-0002-4520-0220
    Introduction: The use of preconditioning strategies (PConSt) alone has a positive impact on performance. The aim of this study will be to understand the effects of combined preconditioning strategies on performance. Materials and methods: The following PConSt were combined: morning resistance exercise (MRE), active warm-up (AW-U), hormonal preconditioning ( HP), post-activation potentiation (PAP) and ischemic preconditioning (IPC). Seventeen recreational active male (age: 24.45 +/- 3.55 years, height: 181.26 +/- 5.76 cm, body weight: 79.82 +/- 233 kg) volunteered for this study. The Wingate anaerobic power and capacity test (WAnT) was used to determine anaerobic performance. All participants were randomly assigned to pre-test, PConSt and Sham interventions. For the PConSt group, MRE, IP, AW-U, HP and PAP were implemented sequentially before the WAnT. No effect strategies were used for the Sham intervention. Results: The findings indicated significant increases in anaerobic performance after combined training in the Peak Power (PP) and Performance Decrement (p < 0.05). A percentage change of 18.11% was found in the PP values obtained after PConSt and Sham interventions, and an increase of 9.55% was observed when the percentage increase from the sham intervention was removed in order to eliminate the psychological effect. Conclusion: It was found that a combined preconditioning strategy intervention increases anaerobic performance.

    Associations between Life-Time Physical Activity Levels, Sedentary Time and Health Outcomes among Older Adults
    (2020) Yilmaz, Fikriye; Yilmaz, Atakan; 0000-0002-4520-0220; AAZ-4775-2020; AAM-8875-2021
    Study Objectives: The aim of the study was to evaluate the associations between the participation levels of the elderly in physical activities through their lives, their sedentary time, and health outcomes. Methods: The data of the study were collected in 2017 with a questionnaire, in which 300 older adults were selected by convenience sampling method in Ankara, Turkey. The questionnaire consists of questions for determining the socio-demographic characteristics and health status of older adults, life-time physical activity indicators, and sedentary time. The research was evaluated with descriptive statistics, Chi-square analysis, Independent Samples t-test, and Pearson correlation coefficient. Results: 53.7% of the 300 older adults participating in the study were female and the average age was 67.74 +/- 3.67 years. 58.3% of the participants were categorized as physically "active" currently or in two periods of their lives. The average sedentary time of participants was 5.7 hours for one day. According to Chi-square analysis, those who were younger, those with lower household income, those who evaluated their health status as good and who had no chronic diseases were physically more active (p < 0.05). Independent samples t-test results demonstrated that the quality of life scores of those who were physically active was higher in comparison to those who were inactive (p < 0.05). According to independent samples t-test, the average sedentary time of those who evaluated their health status as good and those with a chronic disease was found to be shorter. It was found that there was a negative moderately significant relationship between sedentary time and quality of life scores among older adults. Conclusion: In this study, it was concluded that life-time physical activity levels and sedentary time of older adults were an important indicator for their health outcomes.
