Which technology might trainers use for performance improvement?

Trainers may use heart rate monitors and video analysis to enhance the performance of their horses significantly. Heart rate monitors provide valuable data on how a horse is responding to exercise, allowing trainers to tailor workouts more effectively and optimize conditioning programs. By monitoring the horse's heart rate during training and races, trainers can make informed decisions about pacing and recovery, ensuring that the horse is not overworked or under-conditioned.

Video analysis serves a complementary role by allowing trainers to visually assess the horse's movement, technique, and overall performance. This technology enables trainers to identify areas for improvement, analyze the horse's stride, and make necessary adjustments to training regimens. Combining real-time physiological data with video footage creates a comprehensive approach to performance enhancement, resulting in improved training outcomes.

The other options, while relevant to equestrian activities, do not incorporate modern technology focused on enhancing performance. Horse shoes and saddles are essential gear but do not provide performance data. Traditional handwritten logs lack the immediacy and analytical capability that modern technology offers. Basic riding techniques, while fundamental, do not utilize technology that can help track and analyze performance metrics.
