A common misperception about topline is that it can be improved through exercise alone. Lack of exercise – or the wrong type of exercise is often blamed for a poor topline. While exercise alters existing muscles, building new muscles is a different story. The nutritional building blocks of muscle (essential amino acids) must be present in sufficient quantities and balanced with adequate calories to rebuild or augment muscle tissue. In fact, if a horse is worked hard but his diet lacks sufficient amino acids, existing muscle mass can shrink. This can be a slippery slope in some situations, and as muscle atrophy sets in, the belief is that the horse needs to work even harder when in fact the fuel is not present (in the form of nutrition) to help support and repair tissue that is broken down with exercise. Just like human athletes, athletic equine partners need more essential amino acids than maintenance horses to maximize the effects of training and allow the horse to look and feel its best.
Certain exercises are thought to improve topline include hill work, backing exercises, and those that encourage the horse to collect and arc the body. These exercises can help condition muscles, but only if the diet is supporting the muscles through proper nutrition.
Q: What are the Building Blocks of topline muscles?
A) Vitamins and Minerals B) Fresh Air and Water
C) Amino Acids
If you answered C (amino acids) you are correct! One of the most common misperceptions about topline is that it can be improved throughexercise alone. Research shows that horse owners are more likely to believe they can influence their horse’s topline through exercise more than any other method. Additionally, lack of or incorrect exercise is often mistakenly attributed to poor topline development and definition.
While exercise will condition and train existing muscles, it can only help build topline if the nutritionalbuilding blocks of muscles—amino acids—are available in the diet. In fact, if a horse is worked hard enough, and significant amino acids are not present in the diet to build and develop the muscles being trained, muscle mass can be reduced. Just like human athletes, equine athletic partners need more amino acids than the sedentary horse to allow training to be fully utilized and allow the horse look its best.
