Dat had ik gister proberen te achterhalen, maar ik heb het niet kunnen vinden. De tabel staat o.a. op sites van diverse zadelpassers, maar meestal wordt alleen "Freizeit im Sattel" vermeld als bron. Dat tijdschrift is inmiddels van naam veranderd, en op de bijbehorende website heb ik de tabel niet kunnen vinden (nou is mijn Duits ook niet al te best, misschien dat de oorspronkelijke tabel (hopelijk met literatuurverwijzingen) via Google te vinden is met een goede zoekvraag in het Duits).
Ik was ook erg benieuwd waar de percentages op gebaseerd zijn.
Heb nog wel dit gevonden (
http://www.gaitedhorses.net/Articles/HRiderGuide.shtml):"Be Sure Your Horse Measures Up
The U.S. Calvary published “The Cavalry Manual of Horse Management”, by Frederick L. Devereux, Jr., in 1941. He recommended that the collective weight of rider and gear not exceed 20% of the total weight of the horse. These were horses in top condition whose riders’ very lives depended on the horse's ability to carry them long miles, often at speed. It stands to reason that if they were to incorporate a margin of error, it would be on the side of the horse being overly capable of carrying its rider, rather than less so.
Comparably, a study of 374 competitive trail riding horses compared horse/rider weight relationships. They concluded that these horses can easily carry over 30% of their body weight for 100 miles and not only compete, but compete well. As would be expected, good body condition and bone structure were found to be paramount. Bone structure was evaluated using the front leg cannon bones as representative of general structure.
Measurement Test
1. Add up the total weight of the horse, rider and tack. (See TGH Summer 1998, page 37.)
Our example: Damascus, Lady + tack = 1188 pounds.
2. Measure the circumference of the cannon bone midway between the knee and fetlock.
Our example: Damascus, 7.5 inches.
3. Divide this total weight by the circumference.
Our example: 1188 ÷ 7.5 = 158.4
3. Divide the result by two.
Our example: 158.4 ÷ 2 = 79.2
Values near 75 are great, below 75, even better. Values from 75/80 are acceptable. Values over 80 indicate weaker legs and a need to train carefully, especially downhill. Values over 85 suggest you need a horse with more substance.
Damascus rates near the end of the acceptable range, but should still be able to carry Lady in style, comfortably.
*Note that cannon bone circumference (as overall bone substance) increases with the horse's fitness level, so if he is borderline, like Damascus, it doesn't necessarily mean you're too big for him. By “racking” up Long - slow - distance (LSD) miles, which builds up bone over time, he may measure up yet. Be patient: it can take up to three years for bone to remodel."
