Plasmatic levels of carnosine and L-histidine in horses under treadmill standardised exercise
Observational studyHorses
- Design
- Observational study
- Subjects
- not stated in the abstract
- Dose used in the study
- not applicable (no supplement given)
- Duration
- two standardised treadmill exercise tests 48 hours apart
- What was measured
- Plasma carnosine and L-histidine during two standardised treadmill exercise tests; correlation between the two; baseline values before each test.
What the authors reported
The authors report that both compounds rose during each test, with histidine always higher than carnosine. Carnosine changed within the first test (P<0.005); both changed within the second test and between tests (P<0.05). The two were positively correlated within each horse (P<0.05). Baseline values were higher before the second test, which the authors attribute to absent plasma carnosinase and possible subclinical muscle damage in untrained horses. They propose plasma carnosine as a clinical indicator of muscle damage.
Limits of this study
