    Do walking programs affect C-reactive protein, osteoprotegerin and soluble receptor activator of nuclear factor-kappaβ ligand?
    (2009) Esen H.; Büyükyazi G.; Ulman C.; Taneli F.; Ari Z.; Gözlükaya F.; Tikiz H.
    Aim: To examine the effects of 10-week walking programs on maximal oxygen consumption, body composition, serum lipids, highly-sensitive C-reactive protein, osteoprotegerin and soluble receptor activator of nuclear factor-kappaβ ligand. Method: Twenty-seven middle-aged men (40-60years) walked for ten weeks, five days per week, 40-52min per day at either moderate or high intensity (∼5.95±0.26km/h and ∼7.64±0.36km/h; 50-55% and 70-75% maximum heart rate reserve, respectively). Non-walking, sedentary men served as controls (n=13). Estimated maximal oxygen consumption, body composition, lipid profile, highly-sensitive C-reactive protein, osteoprotegerin and soluble receptor activator of nuclear factor-kappaβ ligand were determined before and after the study. Results: After 10 weeks, estimated maximal oxygen consumption improved in both exercise groups (p<.05), favoring high-intensity group (p<.05). Body weight, percent body fat, and body mass index reduced significantly in both exercise groups (p<.05). Walking programs did not cause any significant changes in blood lipids, highly-sensitive Creactive protein, and osteoprotegerin levels; however, soluble receptor activator of nuclear factor-kappaβ ligand levels were found to decrease in high-intensity group (p<.05) and the change observed in both exercise groups was different from the change in control group (p<.05). Conclusion: For protective effects against cardiac risk factors and arterial calcification, high-intensity walking programs are advisable due to the greater improvements in soluble receptor activator of nuclear factor-kappaβ ligand and estimated maximal oxygen consumption. © TurkJBiochem.com.

    Examining acute changes in some serum biochemical markers of brain tissue damage after free and Greco-Roman style wrestling; [serbest ve grekoromen güreşi takiben beyin doku hasarını gösteren bazı serum biyokimyasal markerlerindeki akut deǧişimin i̇ncelenmesi]
    (Turkish Biochemistry Society, 2010) Arslan F.; Büyükyazi G.; Ulman C.; Taneli F.; Gözlükaya F.; Çalkan M.
    Purpose: This study aimed to examine the acute changes in some serum biochemical markers due to overloading in one match of Greco-Roman and free style wrestling competitions. Method: In a repeated measures design, serum samples were collected before and 20 minutes after the first matches of the wrestlers during local wrestling competitions; subsequently analyzed for S-100B and heart-type fatty acid-binding protein. Study groups composed of Greco-Roman (n=15) and free style (n=16) wrestling groups of ≥19 year-old, healthy, male wrestlers. All matches were video-recorded for trauma analyses for each player. Results: Study results showed increments of 109% (p=.007) and 145% (p=.001) in serum S-100B; 63% (p=.023) and 198% (p=.002) in heart-type fatty acid-binding protein levels from pre to post match in the free and Greco-Roman style groups, respectively. The comparison of the increases obtained in the measured parameters did not reveal significant differences between the groups. Conclusion: Due to the significant increases in serum markers, there may be a possible additive effect of traumas in causing brain injuries/head traumas in free and Greco-Roman style wrestling. However, different style wrestling did not affect serum markers indicating brain tissue damage differently. © TurkJBiochem.com.
