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.

(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.
The effect of combined preconditioning strategies on isokinetic strength in well trained kickboxers
(2018) Yilmaz, Atakan; Gurses, V.V.; Gulsen, Mehmet; 0000-0002-8826-8524
Purpose: The use of preconditioning strategies (PconSt) alone has a positive impact on performance. However, it is thought that there will be more impact on the performance of the combined preconditioning strategies, and this is the first work to prove it. This study was to examine the effect of combined preconditioning strategies on isokinetic strength in well-trained kickboxers. Material: The following preconditioning strategies were combined: morning resistance exercise (MRE), ischemic preconditioning (IP), active warm-up (AW-U), hormonal preconditioning (HP) and post-activation potentiation (PAP). Fifteen well-trained male kickboxers (age: 22.38 +/- 4.01years, height: 182.23 +/- 1.05cm, body mass: 77.67 +/- 8.01kg) volunteered for this study. Peak isokinetic knee extension and flexion moment were determined at 60 degrees/s, 180 degrees/s and 240 degrees/s bilaterally. All participants performed the pre-test and then were randomly divided into Sham and PconSt groups on separate days. For the PconSt group, MRE, IP, AW-U, HP and PAP were implemented sequentially before test. Results: The findings indicated significant increase in strength after combined training in the PconSt groups for right leg flexion at 180 degrees/s flexion (p < 0.05). The average percentage strength difference between sham and PconSt groups was 4.12 +/- 8.95%. Conclusions: This study showed that a combined preconditioning strategy increased isokinetic strength.
The Effects of Quadriceps Kinesio Taping on Aerobic and Anaerobic Exercise Performance in Healthy Participants: A Randomized Controlled Study
(2016) Duruturk, Neslihan; Pekyavas, Nihan Ozunlu; Yilmaz, Atakan; Karatas, Metin; https://orcid.org/0000-0002-4520-0220; AAD-3908-2020; AAC-6522-2020; AAM-8875-2021
Objective: Aerobic and anaerobic exercise capacities are important components of athletic performance. The use of Kinesio Taping (R) (KT) as a supplementary treatment in athletic settings has increased in the recent years. KT can facilitate muscle contraction, which may be useful for improving performance. The purpose of this study was to determine whether the application of KT to the quadriceps muscle has any effect on anaerobic and aerobic performance in young healthy individuals. Design: Randomized, controlled, double-blind clinical study. Setting: Baskent University, Faculty of Health Sciences, Department of Physiotherapy and Rehabilitation. Patients: Thirty-two healthy male participants were randomly assigned to either the KT group or a sham KT (SKT) group. Interventions: The KT muscle facilitation technique was applied to the quadriceps muscle bilaterally and measurements were taken 45 min later to ensure full adhesion. Main Outcome Measures: The Wingate cycle ergometer test was used to assess peak anaerobic power (peak AnP, in Watts) and exercise capacity (Watt/kg), while the 6-minute walk test (6MWT) was used to assess aerobic exercise capacity of the participants. Comparisons between groups were performed using the nonparametric Mann-Whitney U test, while those between baseline and posttaping used the nonparametric Wilcoxon test. Results: No significant difference was found between the two groups in the aerobic or anaerobic test parameters (p > .05). Within the groups, a significant improvement in time factors in peak AnP (929.7 2 +/- 184.37 W to 1043.49 +/- 224.42 W) was found only in the KT group (p = .028) and no other parameter was significantly different (p > .05). Conclusions: KT applied to the quadriceps muscle can positively improve anaerobic exercise performance and athletic performance capacity. However, KT did not affect aerobic capacity. Further research is needed to show that KT can improve and support anaerobic and aerobic exercise capacity in healthy participants or athletes.
