Biomechanics of the trot, and posting?

raising hand I believe in riding serviceably sound horses, which this horse appears to be.

I have a horse who had double hind suspensory tears (which we tried to heal with PRP, stem cell & shockwave) and has mild dsld. I tried to retire him. He is absolutely miserable, cribs like a fiend, and becomes absolutely horrible to handle when he is not worked.

So he’s worked lightly. And he loves it. Some days he comes out absolutely sound. Some days he’s more than a little gimpy (we don’t do much on those days and he gets some meds afterward). I work the other horses first, and he gets antsy and wants to join in the fun. He’s an ex-show horse that LOVES his routine. It makes him feel safe and comfortable, so we try to accommodate him.

I know many school horses like this, that if you just trot on the opposite diagonal, it’s more comfortable for them given their hind-end ouchies. I doubt very much that the body weight on the leg is what is causing it unless you are very heavy. I suspect that compensation in their muscles due to the injury (resting it more often may shorten the muscles, or have them stand in a way that torques the muscles) and that the sitting phase actually is a slight pain in the back on that side.

I’m not terribly old (mid-40s) but someone would put me out to pasture if I were a horse, but I know that strengthening is key to me not falling apart even just walking around after dual hip-surgeries and numerous athletic injuries. The key is judicious use of pain meds, loads of stretching, and I can’t go as gung-ho as I was in my 20s.

Good luck with your guy! He sounds like a peach :slight_smile:

Right now I get to ride OLD lesson horses (20s to nearly 30 or so.)

During my rides they all tend to have some sort of gimpiness.

The first thing I use is a BOT shimmable saddle pad, then a BOT exercise sheet, their butt blanket. This helps them warm their muscles up without much stress or work.

On one horse, with treated navicular and around 28 years old (I think) I’ve added the BOT exercise boots and the Fenwick pastern wraps. These help a good deal.

I also put a BOT neck rug on the horses while I ride, plus the Fenwick and BOT stuff that goes over the poll and upper neck.

I think when a horse starts hurting a little bit that they compensate by changing their movement. This can end up giving me irregular rides with “impure” gaits. By making these elderly horses more comfortable they can cheerfully do a few more years of lesson work if their workload is cut back according to their abilities, and I do not feel like I am being tossed around in the saddle as they try to tell me that they are just not comfortable somewhere.

Is it perfect? No. But these horses are the equivalent of 70-80-90 year old humans and how many humans of that age are perfect physically? I sure am not, I use the BOT and Fenwick stuff too and it really helps me have a more pleasant old age.

Well, try to soften your heart and find some compassion toward me, RB. I have spent my horse life in a series of apparently suck barns where we were taught to rise with the outside foreleg. So, obviously there are gaps in my education.

Uhh…outside leg forward is correct. “Rise and Fall with the leg on the wall”. Consider me confused.

You’re right: I typed it backwards.

But if you already knew this, why did you ask? I honestly can’t figure out what you’re after.

Sometimes maybe we just want to find out if we might be missing something in our understanding. Maybe it’s not always so easy to create the question when we’re unsure of our gaps in knowledge. For example, I have been riding grand prix horses for years, and I can tell you it’s only recently that I have had a trainer that worked with me to make sure I knew the footfall of each gait. Sure, I should have known that. But I didn’t know enough to know what I didn’t know. (Yes, it’s easier to ride movements when the horse knows what to do, and yes, you can have big gaps in knowledge when you do that). But from my vantage point, anyone trying to ask a question to help them learn anything is a good thing, and if you don’t have anything to add, that’s okay also.

Yes, agree with this. If your horse actively resists your posting in a way that should help him, I would suggest he is lame.

But that could be lame because he is very stiff, weaker on one side, or in pain. It doesn’t necessarily mean you shouldn’t ride him, but I would probably want a lameness eval. If there was a relatively easy solution - e.g. NSAIDs, joint support and/or chiro or PT to strengthen…I would want to do it.

I wouldn’t spend a ton of money on a lameness workup for an older horse, but a good lameness vet can probably give you some ideas as to the source of the lameness (e.g. front or back leg, or something else), and how to improve. It might never make him sound but if it can make him more comfortable for riding it is worth considering.

See post 7…

(I know OP and her horse IRL. The horse is just as she describes – he is a cheerful, willing, go-ey little fella. Think stereotypical Morgan who just. won’t. quit.)

Thank you, QA. You are obviously a very intelligent, insightful, person, no doubt having been trained to that high standard by your own stunning Morgan. :smile:

*raises hand as another rider who rides a sometimes questionably sound horse

And what’s worse, this horse doesn’t particularly love being ridden. Certainly not as the OP describes her gelding.

But if I don’t ride him, at some low level - and keep him in regular work (tried to retire him once, it was a disaster) - he will absolutely and utterly fall apart physically. He’ll go back to every physical compensatory mechanism he’s clutched on to for his entire life (he’s 18) before he came to me a few years ago. He’ll lose all mobility in his SI and back, get hard in the base of his neck, start landing toe first again in front and beat the heck out of his already arthritic hocks. He’d literally cripple himself. Being ridden gently 4-5 days a week, constantly reminding him to carry himself properly, is what is holding him together. That and Equioxx and routine chiropractic work.

It’s often not as cut and dry as “just retire them”.

To answer the original question.

When you are posting on the “correct” diagonal, the inside hind pushes you into the “up” phase of the post. If he pushes more strongly with one hind leg, then posting on THAT diagonal will feel easier than posting on the other diagonal (where you get a smaller push).

The REASON the horse pushes off more strongly on one side COULD be pain, but it could also be a lack of strength on one side.

I’ve been at a new barn for a year. 20 horses, very nice, and very quiet. I had to move my 27-year-old Paint gelding because he was not receiving proper care after 19 years at the old location. The BO there started his downhill slide when she locked the farm up for April 2020. His mildly ailing knee hardened up and he lost a lot of flexion He wasn’t getting enough hay. The new BO took him under her wing. He gained back a few hundred pounds and his personality redeveloped. He doesn’t look 27 (I’m told I don’t look 73) and he doesn’t act it either. I retired him from riding in July. He is too special to push to serviceably sound. He has boundless energy and should get to 30. We have taken up long lining which we both enjoy. I’m better at it than I thought I would be. It appears that no one there thinks I can ride, let alone know anything about horses. The only drawback is that when you aren’t riding you aren’t developing social connections. A good number of them aren’t worth the effort.

The first thing I noticed is that none of them, as in no one, knows how to post the trot. They aren’t soft and following the motion. They steer with the reins, not their bodies. They aren’t taking advantage of all that power in the back end. They are pushing themselves up and down with their legs. At the top they stiffen up, poke their belly out and sit down. Not a lick of softness anywhere. I think most of them don’t know about the elbow. You know, that joint between the wrist and shoulder that can bend. The mediocre instructor is okay compared to the totally incapable one. I heard the latter a couple of days ago telling the rider, who was trotting, to set up a little resistance. Then she had her pull the head around with the left rein low, going out and back toward her hip. I think it was supposed to be bend. She gets paid for that.

One of the younger women bought a nice gray gelding last spring. Very nice mover. She complained when she first had him that she was exhausted from posting his trot. I couldn’t imagine why. She’s in her 20s, tall, thin and athletic. The horse doesn’t have a gigantic trot. It must be the part where you push yourself up and down with your legs, stiffen up and push your belly out.

Her next project was teaching him how to pick up the right (vs. left) lead. Took two weeks. It was obvious within a couple of seconds that she was blocking him. There isn’t a transition. She keeps posting and sits down when she asks for the canter. Her horse is very consistent. He can’t get his back end under so he gives her the left "wrong " lead. That’s all he could do. He was very consistent. I haven’t watched them lately.

I miss riding my old buddy. We have a lameness vet. We had a shot at getting back to light riding but it wasn’t to be. I may be a mediocre rider, but can watch my last lesson with Susan Harris in 11/19 on video. She made some small changes to my saddle. Then we focused on my seat bones which helped my balance and posture. My posting is soft and he used his trot instead the relaxed lope. I followed his motion and used his energy to push me up. I managed to stand in the stirrups at the trot far longer than I imagined. I miss Susan so much (she passed away in March 2021). She set us up for 5 more months of fun with plenty of trotting.
