As a horse comes down on the opposite side of a fence or jump he lands first on one front hoove and then the other followed by the two hind feet. So depending on which lead he lands on that leg takes the most weight and stress. So the muscles involved in a landing are the shoulder muscles and the muscles and tendons down the front legs. Of course virtually all the muscles are used when going over fences. The powerful muscles in the horse's haunches launch him into the air and over the top rail. The back muscles round and arc to support the rider over the highest part of the jump and then the shoulder and front legs take the weight of the horse as he lands.
Horses that are more adapted to the sport of eventing. Eventing horses have to be graceful and strong for the Dressage portion, agile and fast for the stadium jumping portion, and powerful, brave and intelligent for the cross-country jumping phase. not all horses can take the stress of eventing
If you mean a sport, there are two sports that incorporate jumping: Show jumping and Three Day Eventing, which has a Dressage phase, a Cross-country phase, and a Show jumping phase. If you mean breeds, there are many, many breeds that can jump. Generally, the only breeds that aren't regularly using for jumping are draft horses, like clydesdales, or particularly stocky or tiny ponies. Breeds that have known to excel in jumping are Thoroughbreds, Hanoverians, Dutch Warmbloods, Trakehners, Oldenburgs, (and other warmbloods), Selle Francais, Appendix Quarter Horses, Connemara ponies, Sport Ponies, Anglo-Arabs, etc. The individual horse is more important than the breed, however.
G0 phase
Any phase.
A Muscle Twitch is a single contraction of skeletal muscle. The three distinct phases are latent, contraction, and relaxation. Latent Phase: Is the interval from the stimulus application until the muscle begins to contract (shorten). Note that there is no traced activity during this phase, but there are some electrical and chemical changes taking place during this phase. Contraction Phase: This phase is when the muscle fibers shorten, the tracings will show during this phase (a) peak(s). Relaxation Phase: This phase is represented by the downward curve in your tracings, this is when the muscle is going back to its original state of relaxation and the muscle will once again lengthen

The deep muscle of the thorax that promote the inspiratory phase of breathing is the external intercostal. It is a muscle that originates from the lower border of a rib.

The body process that involves over 22 muscle groups and includes the buccal phase and the pharyngeal-esophageal phase is called swallowing. Another term for it is deglutition.
