Effect of Regular Aerobic Training on Serum C-Reactive Protein and Il-6 Levels in Obese Women
(Univ Puerto Rico Medical Sciences Campus, 2021) Ozdemir, Cigdem; Ozgunen, Kerem; Gunasti, Ozgur; Ozyol, Funda Coskun; Kurdak, S. Sadi
Objective: This study's objective was to evaluate interleukin-6 (IL-6) and C-reactive protein (CRP) responses and performance changes in obese women after 8 weeks of aerobic training with an intensity of 50 to 60% of their individual maximum oxygen uptake (<(V)over dot>O-2). Methods: A total of 18 sedentary women with an average age of 44.3 (+/- 1.9) years volunteered for this study. Over a period of 8 weeks, in 4 40-minute sessions per week, the participants walked at an exercise intensity that caused their heart rates to increase to levels corresponding to 50 to 60% of their <(V)over dot>O-2 peaks. Blood samples were collected from the participants, both when they were at rest and a couple of minutes after the end of the 1st exercise session. Sampling was repeated in the 4th and 8th weeks, before and after the last training sessions. Results: The participants' body mass indices and weights decreased significantly by the end of the 8th week, while their maximum running speeds and <(V)over dot>O-2 peaks increased significantly. There were no differences in CRP or IL-6 concentrations between the pre- and post-training sessions, but most of the participants' IL-6 levels dropped below 10 pg/ml after 8 weeks of training. Conclusion: Although no significant changes were observed in CRP or IL-6 concentrations, it is important to note that in response to aerobic training, the IL-6 levels of most of the participants fell to what is generally considered acceptable.
Monitoring the Improvement of Muscle Performance Using Isokinetic Dynamometry: a Comparative Analysis Based on the Full Range of Motion Vs. the Valid Isokinetic Sector
(Ios Press, 2017) Ozdemir, Cigdem; Ozgunen, Kerem; Sarpel, Tunay; Gunasti, Ozgur; Bildircin, Caglar; Coskun, Funda; Kurdak, S. Sadi
BACKGROUND: Isokinetic dynamometers measure moment and calculate work and power values, which are generally used to interpret muscle performance. OBJECTIVE: This study aimed to determine the differences of peak moment (PM), work, and power between FRoM and calculated valid isokinetic sector (VIS) data to define the possibility of the misinterpretation of isokinetic dynamometer data. METHODS: Fourteen professional male soccer players who had ACL reconstruction were recruited to the muscle strengthening program which was conducted four days a week for six weeks with increasing training intensity each week. Isokinetic muscle peak moment, work, and power of knee extensors and flexors were measured at angular velocities of 60, 120, 180 and 240 degrees/s. RESULTS: The results of the standard full-RoM (FRoM) report were compared with the calculated VIS data. Analyses of the FRoM data showed that PM, work, and power values for both extensor and flexor muscle groups improved significantly. However, a comparison of FRoM and VIS data showed significant differences for the work and power values at 120, 180 and 240 degrees/s. CONCLUSION: The evaluation of FRoM isokinetic data may cause improper interpretations in muscle performance, particularly for contractions with higher angular velocities.
