Have you heard about the WUT Venn Diagram❓🤔

You can know your hydration levels by measuring your weight (W), urine (U) and thirst (T). This can be incredibly important for jockeys on hot summer racing days. Dr. Douglas Casa of the @K_S_Institute explains.

Weight and potency are not the same thing. A substance can be present in a small amount yet still have a significant effect, while a larger amount of a less potent substance may have little impact.

Staying hydrated is incredibly important in the summer, particularly for jockeys.

Last year, Dr. Douglas Casa of @UConn and @K_S_Institute spoke with racetracks' medical teams about the critical role hydration plays in athlete health and performance. 🔊

Regulatory Veterinarians are essential to protecting the health and welfare of Thoroughbred horses. Though they’re primarily employed by racetracks and state racing commissions, HISA equips them with tools to strengthen their impact.

Jockeys need to maximize both their physical and mental performance to compete at their best.

We asked @Ericcancel85, who's claimed more than 900 victories in his career, how he enhances his mental performance every race day.

Jockey @SanchezMychel has been riding competitively for 14 years, accruing more than 1,900 career wins and more than $66 million in earnings. But what made him fall in love with the sport?

We asked, he answered. 📢

HERF's work is a powerful complement to the progress we already have seen from HISA's racetrack safety and anti-doping rules. These efforts reflect what HISA was always meant to be: a comprehensive, unified approach to making this sport safer for horses and riders alike.

[Horseracing Integrity and Safety Authority @hisa_us]

Last quarter, HISA racetracks reported a 0.95 racing-related equine fatality rate, meaning 99.91% of starts occurred without a fatality. 📊

Thanks to the HISA Equine Recovery Foundation, 5 horses were saved from fatal injuries in Q1.
