Methods used to study exercise physiology in horses Flashcards
name 3 things used for speed control
treadmills
trained riders/drivers
“Equisizers”
3 ways to control exercise other than speed control
weight load
jump height
use of side reins
what is the original name of the treadmill for horses
boat
2 advantages of using treadmills
standardized conditions
timed measurements/samples to be taken
name 3 standardized conditions sustained by treadmills
environment
slope
speed
3 examples of timed measurements/samples that can be taken while using a treadmill
blood samples
ventilation
respiratory gases
what are aqua treadmills usually used for
conditioning & rehab
name 4 drawbacks to using treadmills
- no rider
- physiological responses might not be same as under “performance” conditions
- gait is different
- only certain types of exercise can be assessed
how is not having a rider on a treadmill compensated
an incline
what 2 physiological responses are different on a treadmill compared to “performance”
heart rates
blood lactate levels
how does the gait on a treadmill different from when performing
longer, less frequent
________ more accurately reflects the effects of exercise in a competition setting
field testing
name an advantage of using trained riders/drivers
more flexibility
name 4 drawbacks to trained riders/drivers
less control over environment & level of exertion
human errors
more variation in results
less samples can be obtained
how many slots are usually in an horse “exercizer”
6-8
two drawbacks to horse “exercizers”
can’t collect samples
horse cooperation
what are “exercizers” mostly used for
getting them fit
fixed number of repetitions over a fixed number of jumps at a fixed height
jumping
2 methods of jumping for research purposes
with a rider
down a chute
what is used to create different head positions to study effects of flexion on cervical spine stress and neuromuscular function
use of side reins
4 factors used to monitor exertion
heart rate
temperature
respiratory gases
blood variables
increased speed = _____ lactate
increased
name the most common blood variable measured
lactate
4 sample collection procedures
blood samples
x-rays
muscle biopsies
sweat production rate/composition
