“…It has been proposed that the exercise induces change in plasma volume, electrolytes, and acid-base balance that can provoke alterations in urea and creatinine serum levels, depending on several factors, as exercise intensity and duration, training level, thermoregulation, and weather conditions. 44 The lack of significant increase in urea and creatinine levels in our study indicates that exercise intensity and duration were not sufficient to cause changes in corporal fluids.…”

This study was designed to examine if diphenyl diselenide (PhSe) 2 , an organoselenium compound, attenuates oxidative stress caused by acute physical exercise in skeletal muscle and lungs of mice. Swiss mice were pre-treated with (PhSe) 2 (5 mg kg -1 day -1 ) for 7 days. At the 7th day, the animals were submitted to acute physical exercise which consisted of continuous swimming for 20 min. The animals were euthanized 1 and 24 h after the exercise test. The levels of thiobarbituric acid reactive species (TBARS), non-protein thiols (NPSH) and ascorbic acid and the activity of catalase (CAT) were measured in the lungs and skeletal muscle of mice. Glycogen content was determined in the skeletal muscle of mice. Parameters in plasma (urea and creatinine) were determined. The results demonstrated an increase in TBARS levels induced by acute physical exercise in the skeletal muscle and lungs of mice. Animals submitted to exercise showed an increase in non-enzymatic antioxidant defenses (NPSH and ascorbic acid) in the skeletal muscle. In lungs of mice, activity of CAT was increased. (PhSe) 2 protected against the increase in TBARS levels and ameliorated antioxidant defenses in the skeletal muscle and lungs of mice submitted to physical exercise. These results indicate that acute physical exercise caused a tissue-specific oxidative stress in the skeletal muscle and lungs of mice. (PhSe) 2 protected against oxidative damage induced by acute physical exercise in mice.

“…The increase in LDH, CK or AST was observed in exercised race horses (Harris et al, 1998;Kedzierski and Bergero, 2006), after endurance rides (Marlin et al, 2002;Barton et al, 2003) and also after show-jump competitions (Balogh et al, 2001). The total plasma protein also increases after exercise as a result of blood dehydration, but these changes can be lowered by the conditioning process (Hinchcliff et al, 2002).…”

The aim of this study was to compare the changes in hematological and biochemical parameters in race horses subjected to standardized field exercise tests. The tests were performed two times: in May, at the beginning of the racing season and then four months later. Ten horses were studied in May (5 Thoroughbreds and 5 Purebred Arabian horses). Eight horses were studied in September (4 Thoroughbreds and 4 Arabian horses). For each horse, venous blood samples were collected at rest, after warm-up, just after the end of each gallop, and 30 minutes after the end of the exercise. The concentration of blood lactic acid (LA) hemoglobin (Hb), plasma glucose (Glc), triacylglycerols (TG), glycerol, uric acid (UA), total protein, total thiobarbituric acid-reactive substances (TBARS), the activity of lactate dehydrogenase (LDH), kreatine kinase (CK) and aspartate aminotransferase (AST) and the total antioxidant status (TAS) were determined. The standardized field exercise test performed in September, in comparison to the first test, evoked the lowest increase in blood LA and plasma Glc and TG levels determined during exercise. The rapid return of elevated levels of LA, Hb and UA to their initial values was also observed in September, as compared to data obtained in May

“…Nonetheless, most of the parameters in liver, renal and lipid profile showed minor increases in their levels, with a statistically significant difference observed only for ALT, total protein, and albumin. Rarely, a mild increase in plasma glucose concentration and a decrease in triglyceride level were seen in race horses after the races (2,3,5). Similar to this observation, a significant increase in total protein and albumin concentrations has been reported in humans after a marathon running, and is probably a secondary reaction to the effect of dehydration after the races.…”

“…The limited increase in the two serum muscle enzymes indicates moderate muscular insult due to road transport. Moreover, several authors have reported a mild to moderate increase in plasma CK activity after severe physical stress or exercise (2,3,20). However, rats and turkeys show a significant increase in CK activity even with mild stress or exercise (19,26).…”

The objective of this study was to assess the physiological responses in mature healthy horses prior to an 8 h transport, as well as immediately and 24 h after transportation in a horse truck, under autumn conditions typical for central Poland. The study was conducted on a group of 60 horses of different breed. Horses ranged from 4 to 10 years of age. Venous blood was taken 3 times: Idirectly before loading the horses to the trailer, II -directly after unloading the horses from the trailer, III -after period of 24 h resting. There was no change in the concentrations of urea, cholesterol, creatinine, and magnesium and in the activity of alkaline phosphatase during the three subsequent samplings. Albumin, total protein, alanine aminotransferase, aspartate aminotransferase, total bilirubin, creatine kinase, and triglycerides were mostly influenced by the transport. The obtained results indicate that the transportation of horses alters concentrations of physiological variables of their metabolism.
