Oxidative stress in thoroughbreds during official 1800-metre races
نویسندگان
چکیده
The aim of the present study was to find possible relationships between physical exercise and oxidative stress in thoroughbreds during official races. For this purpose six healthy and trained thoroughbreds were used. Blood samples were collected from all horses at rest immediately after the race, and 30 and 180 min. after the race. The following parameters were assessed on obtained serum using the spectrophotometer method: lactate dehydrogenase, creatine kinase, reactive oxygen species, thiol antioxidant barrier and antioxidant barrier. Obtained results showed the highly significant effect of exercise on some of the studied parameters: LDH, F(3,15) = 49.85, P<0.0001; ROMs, F(3,15) = 60.71, P<0.0001; Oxy-adsorbent, F(3,15) = 393.70, P<0.0001. No statistical significant differences were observed for CK and SHP. Our results appear to indicate that during official races thoroughbreds generate free radicals, but are unable to determine a significant lyses of skeletal muscle cells.

Genetic correlations between racing performance at different racing distances in Thoroughbreds and Arab horses
The purpose of this study was to find out whether abilities to win races of different distances are different traits. Data included information on 14 665 starts of 1 646 Thoroughbreds, aged 2 to 9 years and on 10 862 starts of 1 145 Arab horses, aged 3 to 10 years. The data comprised seven racing distances for Thoroughbred horses, i.e. 1 000, 1 200, 1 300, 1 400, 1 600, 1 800, >1 800 m, and fiv...

Oxidative Stress in Horses in Three 80 km Races
Oxidative stress and muscle membrane leakage were compared in horses finishing (F; 24) or not finishing (NF; 16) in Research Ride 2002 (R2). These data were also compared to previous rides—Old Dominion (OD; more competitive) and Research Ride 2001 (R1; less competitive). For R2, blood samples were taken before (PRE), 27, 48 and 80 km, and 170 to 190 min during recovery. Blood was analyzed for p...
