Öğe Acute effects of recreational soccer on inflammatory response and cardiac and skeletal muscle damage indicators(Univ Press, 2019) Aslant, Alper; Salci, Yasar; Bicer, Bilal; Savas, Nazan; Duran, NizamiIntroduction: Previous studies have indicated that acute bouts of strenuous, long duration exercise induce significant increases in the inflammatory profile and cardiovascular risk markers. Although recreational soccer (RS) is a widespread activity there are no data on this topic. Thus, the aim of this study was to examine RS-induced changes in inflammatory, cardiac, and skeletal muscle damage indicators in young and middle-aged males. Methods: Twelve young and 11 middle-aged males participated in the study. The participants played 6v6 1 h RS, where heart rate (HR) responses and external loads (distance covered, number of accelerations/decelerations) were determined. Blood samples were taken immediately prior to and following the matches, and 2 h, 4 h, 24 h, 48 h, and 72 h later. Results: Absolute HR responses and the number of accelerations and decelerations were higher in young participants than the middle-aged participants (p < 0.05). RS increased high sensitivity cardiac troponin I (hs-cTnI) in almost all participants. A total of 83.3% of the young participants exceeded the upper reference limit (URL), whereas none of the middle-aged participants exceeded the URL. Hs-cTnI levels returned to baseline after 24 and 48 h in the middle-aged and young participants, respectively. High sensitivity C-reactive protein (hs-CRP) and creatine kinase (CK) increased in the middle-aged participants (p < 0.05), and in the young participants, though not significantly (p > 0.05). RS also led to significant increases in lactate dehydrogenase (LDH) in both groups (p < 0.05). Hs-CRP, CK, and LDH values returned to baseline levels within 48 to 72 h, except for the LDH values of the young participants. Conclusion: RS induced short-term increases in cardiac and skeletal muscle damage markers and the inflammatory profile in young and middle-aged RS participants.Öğe The effects of eccentric hamstring training on lower extremity strength and landing kinetics in recreational female athletes(Ios Press, 2013) Salci, Yasar; Yildirim, Ahmet; Celik, Ozgur; Ak, Emre; Kocak, Settar; Korkusuz, FezaHamstring training involving eccentric loading is an important protective factor in hamstring injuries. However, the effect of this mode of training on lower extremity loading in landing maneuver performance is unknown. The purpose of this study was to examine variations in eccentric hamstring strength after 10-weeks training program and the possible changes in landing kinetics. Twenty five recreational female athletes were voluntarily assigned to the Nordic Hamstraing Strength Training (N = 13) or control groups (N = 12). The training group performed 10-weeks eccentric hamstring strength training program. Baseline measures of landing kinetics were collected using a force plate while strength data was evaluated using an isokinetic dynamometer. Results indicated that NHST group increased their eccentric hamstring strength (pre = 2.34 +/- 0.28, post = 2.57 +/- 0.25 Nm/kgbw; p < 0.05) after training program albeit without changes in the dynamic control ratio. There were also significant decreases in peak anterior-posterior ground reaction force (PAPGRF; pre = 1.14 +/- 0.21 BW, post = 0.85 +/- 0.27 BW; p < 0.05) and peak vertical ground reaction force (PVGRF; pre = 6.27 +/- 1.00 BW, post = 5.34 +/- 1.01 BW; p < 0.05) scores for NHST group. The present study supports the positive effect of eccentric hamstring strength in altering landing kinetics in order to decrease the applied forces.Öğe The Effects of Weekly Recreational Soccer Intervention on the Physical Fitness Level of Sedentary Young Men(Montenegrin Sports Acad, 2019) Aslan, Alper; Salci, Yasar; Guvenc, AlpayRecreational soccer (RS) has a great potential to improve the physical fitness levels of diverse populations when performed two to three times per week. However, to date, only Beato and collaborators have examined the effects of once-a-week RS on physical fitness, even though this frequency is widespread among participants. 'thus, this study aimed to investigate the effect of weekly performed RS intervention on components of physical fitness in sedentary young men. Twenty-healthy men aged 20-27 years were randomly assigned to a soccer (n=10) group or a control (n=10) group. Participants in the soccer group played a 60-min. small-sided soccer game once-a-week for eight weeks. Before and after the intervention period, body composition, aerobic fitness, blood pressure, anaerobic performance and isokinetic leg strength were assessed. After eight weeks of the once-a-week intervention period, in the soccer group, body fat and thickness of skinfolds were significantly decreased (p<0.05). Peak oxygen uptake, running distance, squat and countermovement jump (p<0.01), concentric quadriceps and eccentric hamstring strength were also improved only in the soccer group (p<0.05). In contrast, other variables, including body mass (BM), body mass index (BMI), fat-free mass (FFM), heart rate responses, blood pressure, and anaerobic performance remained the same as before the intervention period (p>0.05). Participating in weekly RS programme can lead to some health and performance benefits. However, the people who wish to further improve their health status and performance level should increase the frequency of RS activity.Öğe The metabolic demands and ability to sustain work outputs during kickboxing competitions(Routledge Journals, Taylor & Francis Ltd, 2015) Salci, YasarThe aim of this study was to determine heart rates, lactate levels and rates of perceived exertion responses to kickboxing competitions. A further aim was to evaluate the number of attacks and leg strength throughout the competitions. Ten kickboxers participated in the study and completed two kickboxing fights with the same opponent, at 1 week apart. After each round, lactate levels and rates of perceived exertion (CR-10 scale) were recorded, and heart rates were measured continuously throughout the competitions. One fighter from each fight was isokinetically tested for identifying lower extremity strength variations during kickboxing competitions. Each fight was also recorded by a video camera to analyse the technical actions performed. The study results suggest that metabolic demands imposed on kickboxing athletes progressively increase from round one to round three, represented by mean cardiovascular responses, lactate levels and rates of perceived exertion. However, concentric quadriceps strength, hamstring strength, hamstring-to-quadriceps strength ratio, and number of kicking and punching attempts decreased significantly over the course of consecutive rounds. In summary, it is observed that kickboxers experienced a higher physiological stress and lower work outputs during consecutive rounds.Öğe Serum cartilage oligomeric matrix protein accumulation decreases significantly after 12 weeks of running but not swimming and cycling training - A randomised controlled trial(Elsevier Science Bv, 2013) Celik, Ozgur; Salci, Yasar; Ak, Emre; Kalacı, Aydıner; Korkusuz, FezaBackground: Acute effects of physical exercise on the deformational behaviour of articular cartilage and changes in cartilage oligomeric matrix protein (COMP) are definite. However, conclusive positive effects of fitness exercise on functional adaptation of articular cartilage have not been proved. Aim: Therefore, in this parallel-group randomised controlled trial, we tested the hypothesis that adequate amount of physical exercise with enough impact would be able to stimulate the functional behaviour of articular cartilage. Methods: We evaluated 44 healthy males for their physical-fitness levels and their blood samples were obtained before, immediately after and 0.5 h after a 30-min walking exercise. Thereafter, participants were assigned to the running, the cycling, the swimming and the control groups. At the end of 12 weeks of intervention, the same measurement procedures were applied. Mixed repeated-measures analysis of variance (ANOVA) design was used for statistics. (Level of evidence: 2). Results: Pre-test measurements showed that 30 min of walking significantly increased serum-COMP levels in all groups. The post-tests revealed that the COMP level of all groups, except running, showed an increase after a 30-min walking activity. Conclusion: Overall, it was concluded that, 12 weeks of regular, weight-bearing, high-impact physical exercise (i.e., running) decreases the deformational effect of walking activity. This finding is an evidence of functional adaptation of articular cartilage to specific environmental requirements. (C) 2012 Elsevier B.V. All rights reserved.
