Muscle recovery is where performance gains are actually made. Training breaks muscle fibres down; the recovery period is when they rebuild stronger. A horse that does not recover properly between sessions accumulates damage, loses condition and becomes injury-prone.
The physiology of muscle fatigue
During intense work, muscles produce energy through anaerobic glycolysis when oxygen demand exceeds supply. This produces lactic acid (more precisely, lactate and hydrogen ions) which acidifies muscle tissue, slows enzyme function and causes the burning sensation of fatigue. In horses, peak lactate values are reached at maximal effort. showjumping, cross-country galloping, sprint work.
Post-exercise, the horse's body clears lactate through oxidation in the heart and liver. This normally takes 30–60 minutes in a fit horse. In unfit horses or after extreme effort, clearance is slower and residual acidosis can last hours.
Signs of incomplete recovery
- Muscle stiffness or tying-up (exertional rhabdomyolysis) in severe cases
- Reluctance to work the day after a competition or hard session
- Shortened stride or unwillingness to use hindquarters
- Elevated resting heart rate the morning after
- Loss of topline despite consistent work
Nutritional support for recovery
- Electrolytes. replace sodium, potassium and magnesium lost through sweat. Essential before rehydration is complete.
- Antioxidants (vitamin E, selenium). exercise produces free radicals that damage muscle cells. Antioxidants neutralise these. Ensure forage and feed supply adequate vitamin E, especially for horses in hard work.
- Anti-lactic acid support. certain supplement formulas help buffer lactate accumulation and speed clearance. Lacta Ease is formulated specifically for this purpose.
- Protein. muscle repair requires amino acids. Horses in hard work need adequate lysine and leucine from their diet.
Practical recovery protocol
- Cool down properly. 15–20 minutes of walking post-work
- Offer water and electrolytes within 30 minutes
- Feed hay before concentrates post-exercise
- Allow box rest or light turnout. movement helps lactate clearance
- Give Lacta Ease the evening before a competition and immediately after intense work
