Re: [RC] weight divisions - Jon . LindermanOh absolutely torque (force* moment)is a big issue when it comes to the effective action of mass or force, that why we use things like pry bars, but then too a taller rider creates more torque than a shorter rider of the same weight. however, when it comes to energetics, mass carried is not just a part, its the majority of the equation. any mechanical or biological machine consumes more energy carrying more mass. I am not comparing towing and carrying, because we all know our trucks can tow far more than we can chunk in the bed of the pickup. But whether its 200 + 30 (rider/saddle) or #230 static from the standpoint of ENERGY......not a significant difference. Not talking about concussion, impact to the spine, etc, but ENERGY. Energy expenditure impacts everything about endurance. Energy transfer is very inefficient, so higher energy expenditure increases heat storage, increasing stress on thermoregulation, increasing stress on the CV system, increasing stress on the gut, and on and on........ Oh I agree its harder on a horse to balance 200# than #150. No argument here. Thats why I think HW horses are amazing animals & harder to come by. I just see the beginings of yet another "its not fair argument." Calls for "mandatory".......ugh. The rule is simple, weight minimum. I know a few riders who compete at fairly light weight classes who must be deluding themselves.......yeah sure 20 years ago they weighed that little, but today? with a saddle? In their case its vanity, not trying to dupe the system. Like the guy who swears his waist is the same as it was in high school problem his inseam dropped 6". Jon
