SUMMARY
Bogossian PM, Vienna RB, de
Almeida FQ da Costa APD, Quirino CR., Hind limb temperature
of horses after a cross country race during a 3-day-event, Onl
J Vet Res., 20(12):749-754, 2016. Early response to specific exercise
modes such as cross-country race in a 3-day-event
remains poorly investigated. The time required for surface temperature of hind
limbs of 11 normal horses to return to baseline after a cross-country race
during a 3-day-event is described. Thermograms of
upper hind limb gluteus, biceps, quadriceps, semitendinosus and semi-membranosus muscles before and immediately after
cross-country racing were done with an infrared FLIR thermovision
cameraTM repeated at 30min
and 2, 6, 12 and 24h after racing. The gluteal muscles exhibited highest
post-race surface temperature of 41.20
± 2.54°C. Baseline
temperatures returned by 2h in all muscles except in gluteal muscle which
delayed to 12h.
