New Report, weight a horse can carry

The Japanese, after numerous tests to do with symmetry of motion have come up with the calculation of 29% of the horse's weight. This includes everything, rider, clothing, saddle and pad. They discovered that when exceeding this the horse loses symmetry of motion, calculated when the horse is ridden in a circle. Does it become difficult for the outside front to cross over the inside front? That indicates the weight is too much. It also concluded that this guidline is inaccurate for disabled riders who have little body control or are quite heavy. In these cases the percentage needs to be lowered in the best interest of the horses. Many questions have been asked regarding weight ratio so I'm hoping this answers your questions.

Interesting. By that study, my 1500 lbs draft cross can carry 435lbs.

THAT'S good to know. My gelding is about 1,450 lbs and my DH is working down to get lower than 250 lbs. Guess the horse will be ok. =b

The study was done on 6 mares, hardly a statisticaly significant amount. The Brits did one not long ago studying 150 horses found that 10% of the horses weight was optimum and 15 % was OK. That one is more statisticly significant but still doesnt take into account the varying breeds and conformations of horses.
You would need to study Thousands if not Millions of horses to make a study statisticly significant and relevant.

This study was done omn relatively small horses( breed standard being 13hh, slender legs), and clearly states it can be performed on different breeds to get an idea how height and build influence the weight carrying capability.
Interesting enough is the study done on Tevis Cup FINISHERS, who carried 32% of their own weight over rough terrain for 100 miles and passed a vet check. Again, rather small, light horses.
10 and even 15%......come on, seriously??????

Over and over it gets pointed out but people ignore it - the report that says 10 & 15% was nothing but a numbers game. There was no actual physical study on the horses. They picked a percent they wanted to consider "too much weight" for the horse and then looked at a large amount of data of horse weight vs. rider weight and any rider that was over 15% was said "too heavy" to report a % of riders that were too heavy for their horses.

Even though this study was only 6 horses, it seems to be a more valid start to the research since it actually looks at the physical effects on the horse. They just need to continue and expand it to a larger group with a larger variety of horses involved.

All I pay my psychiatrist is cost of feed and hay, and he'll listen to me any day!

LOL, I wonder if this report will cause more or less fur and feathers to fly on message boards around the world, than the 10 - 15% one did.

Certainly interesting reading, but again, same as the much quoted study on the 20% rule, such a small sample size as to be of no significant relevance.

I don't know if there will ever be a scientific determination of this, there are just to many variables of rider and horse to make it an easy study. I agree that the Trevis Cup study is probably the best one, a wide range of horses and riders crossing harsh terrain with several vet checks, but althought that is a bigger sample size, to be fair I don't think it actually states what % of the horses were carrying over 20%.

And not to forget the Icelandic horse and the usual Icelandic man...13 h, 300-350kg horses ridden hy at least 6' tall, normally built men, fast, over long distances and not really smooth terrain. The rider's weight I'd put at at least 200 lbs. Plus tack. Horses weighing 660-770lbs. IF they even weigh as much. Pretty close to the Japanese study, I'd say....
