The effects of physical exercise on some plasma enzymes and Ca and P levels in race horses

Özet: Araştırmada materyal olarak 9 adet 2 yaşlı erkek İngiliz atı kullanıldı. Atlar çevresi 150 m olan kuru kum zemine sahip kapalı manejde 10 dakikada 5400 metreyi tırıs olarak koşturuldu. Egzersiz öncesi (0 dak), egzersizin 5 dakikası ve egzersiz bitimi (10 dak.) ile egzersiz sonrası 1/2 , 6, 12 ve 24. saatlerde alınan kan örneklerinde plazma Aspartat-aminotransferaz (AST), Alanin-aminotransferaz (ALT), Gama-glutamiltransferaz (GOT), Alkalin-fosfataz (ALP), Kalsiyum (Ca), Fosfor (P) değişimleri ince-lendi.Plazma AST, ALP ve GGT düzeylerinde egzersiz bitiminde egzersiz öncesine göre hafif bir artış olmasına rağmen farklılıklar istatistiksel olarak önemli değildi. Keza plazma ALT düzeyindeki değişikler de is-tatistiksel önemde bulunmadı. Egzersizle birlikte Ca düzeyinde bir azalma, P düzeyinde ise bir artış saptanmasına karşın egzersiz öncesi döneme oranla meydana gelen bu değişimler istatistiksel olarak önemli bulunmadı.

Yarış atı olarak yetiştirilen atlarda fiziksel egzersizin bazı plazma enzimleri ile Ca ve P düzeylerine etkisi

Summary: In this study nine two-year old, male, English horses which trot 5400 m in 10 minutes on dry sand and closed manage were used.The changes in plasma Aspartate-aminotransferase (AST), Alanine-aminotransferase (ALT), Gamma-glutamyltransferase (GGT), Alkaline-phosphatase (ALP), Calcium (Ca) and Phosphorus (P) levels were me-asured in blood samples which were taken before (at 0 min), at the 5th minute, right after (at 10th min) and 1/2, 6, 12 and 24 hours after the exercise.Although plasma AST, ALP and GGT values were slightly higher in post-exercise period, the diffe-rences were not significant statistically in comparison to the pre-exercise levels. And also changes in plasma ALT were not significant statistically.Although a slight decrease in plasma Ca level and a slight increase in plasma P level was found with exercise, a statistical difference could not found according to the pre-exercise period.
