Metabolic rate increased linearly during and terrestrial environments without specializing in running. Over equivalent velocities, the metabolic rate for locomotor performance in either environment. To examine running was 13–40 % greater than for swimming. The possible energetic constraints on semi-aquatic mammals, minimum cost of transport for swimming (2.61 J N−1 m−1) we compared rates of oxygen consumption for the was equivalent to values for other semi-aquatic mammals. Australian water rat (Hydromys chrysogaster) using The lowest cost for running (2.08 J N−1 m−1) was 20 % lower different locomotor behaviors: swimming and running. than for swimming. When compared with specialists at the Aquatic locomotion was investigated as animals swam in a extremes of the terrestrial–aquatic continuum, the water flume at several speeds, whereas water rats were run energetic costs of locomoting either in water or on land on a treadmill to measure metabolic effort during were high for the semi-aquatic Hydromys chrysogaster. -

Change of Canter Lead Through Trot on the Diagonal
Chapter 19 CHANGES OF LEAD AND FLYING CHANGE OF LEAD Definition Change of Lead Through Trot “This is a change of lead where the horse is brought back to the trot and after a few trot strides, is restarted into a canter with the other leg leading.” [USEF Rule Book DR105] Simple Change of Lead “This is a change of lead where the horse is brought back immediately into walk and, after a few steps, is restarted im- mediately into a canter on the opposite lead, with no steps at the trot.” [USEF Rule Book DR105] Gymnastic Purpose The gymnastic purposes of changes of lead are to help develop, as well as test, the horse’s collection, coordination and balance, and to improve the quality of the canter. Qualities Desired The qualities desired in ‘Changes of Lead through Trot,’ are that the horse maintains his straightness, makes a balanced transition to two to three steps of trot, and strikes off clearly to the new canter lead. The qualities desired in a ‘Simple Change of lead’ are basically the same as the change through the trot except that the transition from canter should go directly to two to three walk steps, and to the new canter lead with no trot steps. The transition to walk must be immediate without any intervening vaguely trot-like strides, but also smooth. The steps must be determined and the four footfalls of the gait must be distinct. The transition to the new canter must also be im- mediate. The horse must canter straight and must constantly remain on the bit.” [Dressage, A Guidebook for the Road to Success, p 103] Aids The aids for changes of lead are the same as the aids for the canter. -

Convert That Trot by Lee Ziegler
trot Page 1 of 5 Convert That Trot by Lee Ziegler It doesn’t happen very often, but sometimes a gaited horse isn’t as ‘gaited’ as he should be. Some of them just seem to prefer to hard trot most or even all of the time. These horses are not as difficult to deal with as their pacing cousins, but they can be frustrating, especially for riders who have bought gaited horses in the hopes of never having to deal with a hard trot again. Horses trot for the same reasons they do any other gait – their conformation, body position, muscle use and neurological “wiring” incline them to do the gait. For a gaited bred horse that trots, in addition to these factors, there may also be a lack of rhythm that causes the horse to miss out on the special harmony that should produce his easy gait. Conformation that inclines to a trot: Horses with functional backs that are shorter than the average for their breed will often trot. Horses with relatively short lumbar spans (the vertebrae between the last rib and the lumbo-sacral junction) will also be more inclined to trot. Low headed horses that stretch easily forward will also be more inclined to trot than higher headed types. Horses with hind and front legs that are about the same length, elbow to ground and stifle to ground, may be inclined to trot. Body/muscle use that inclines to a trot: Horses with slightly rounded backs, and stretched toplines will be inclined to trot. Horses that easily tip their pelvises downward and flex downward from the lumbo-sacral junction will be inclined to trot. -

THE FEI TRAINING SCALE 1. Rhythm
THE FEI TRAINING SCALE 1. Rhythm - The Regularity and Tempo The first step of the training scale that should be established is the rhythm. The regularity is the correct sequence of the footfall, and, the tempo is the speed of the rhythm. The rhythm is the regularity of the beat in all paces. Steps and strides in each variation of the pace should cover equal distances and also be of equal duration remaining in a consistent tempo. The rhythm should also be maintained through the transitions within a pace and in all turns, also in the corners, as well on straight lines. No exercise can be good if the horse is losing rhythm. A loss of rhythm is often a sign of incorrect training. In order to judge the correctness of the rhythm, the judge must know how the horse moves in the basic paces. 2. Suppleness – Elasticity and Freedom from Anxiety Suppleness, together with rhythm, is an essential aim of the preliminary training phase. Even if the rhythm is maintained, the movement cannot be considered correct unless the horse is working through its back and the muscles are free from tension. Suppleness is a central theme throughout the schooling. It should never be neglected and should be constantly checked and reinforced. Only if the horse is physically and mentally free from tension (anxiety) or constraint can it work with suppleness and use itself fully. The horse’s joints should bend and straighten equally on both sides of its body and with each step or stride. The horse should convey the impression that it is putting its whole mind and body into its work. -
Linking Gait Dynamics to Mechanical Cost of Legged Locomotion
REVIEW published: 17 October 2018 doi: 10.3389/frobt.2018.00111 Linking Gait Dynamics to Mechanical Cost of Legged Locomotion David V. Lee 1* and Sarah L. Harris 2 1 School of Life Sciences, University of Nevada Las Vegas, Las Vegas, NV, United States, 2 Department of Electrical and Computer Engineering, University of Nevada Las Vegas, Las Vegas, NV, United States For millenia, legged locomotion has been of central importance to humans for hunting, agriculture, transportation, sport, and warfare. Today, the same principal considerations of locomotor performance and economy apply to legged systems designed to serve, assist, or be worn by humans in urban and natural environments. Energy comes at a premium not only for animals, wherein suitably fast and economical gaits are selected through organic evolution, but also for legged robots that must carry sufficient energy in their batteries. Although a robot’s energy is spent at many levels, from control systems to actuators, we suggest that the mechanical cost of transport is an integral energy expenditure for any legged system—and measuring this cost permits the most direct comparison between gaits of legged animals and robots. Although legged robots have matched or even improved upon total cost of transport of animals, this is typically achieved by choosing extremely slow speeds or by using regenerative mechanisms. Legged robots have not yet reached the low mechanical cost of transport achieved at speeds used by bipedal and quadrupedal animals. Here we consider approaches Edited by: used to analyze gaits and discuss a framework, termed mechanical cost analysis, that Monica A. Daley, can be used to evaluate the economy of legged systems. -

Forelimb Joints Contribute to Locomotor Performance in Reindeer (Rangifer Tarandus) by Maintaining Stability and Storing Energy
Forelimb joints contribute to locomotor performance in reindeer (Rangifer tarandus) by maintaining stability and storing energy Guoyu Li, Rui Zhang, Dianlei Han, Hao Pang, Guolong Yu, Qingqiu Cao, Chen Wang, Lingxi Kong, Wang Chengjin, Wenchao Dong, Tao Li and Jianqiao Li Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun, People's Republic of China ABSTRACT Reindeer (Rangifer tarandus) have lengthy seasonal migrations on land and their feet possess excellent locomotor characteristics that can adapt to complex terrains. In this study, the kinematics and vertical ground reaction force (GRF) of reindeer forelimb joints (interphalangeal joint b, metacarpophalangeal joint c, and wrist joint d) under walk, trot 1, and trot 2 were measured using a motion tracking system and Footscan pressure plates. Significant differences among different locomotor activities were observed in the joint angles, but not in changes of the joint angles (αb, αc , αd ) during the stance phase. Peak vertical GRF increased as locomotor speed increased. Net joint moment, power, and work at the forelimb joints were calculated via inverse dynamics. The peak joint moment and net joint power related to the vertical GRF increased as locomotor speed increased. The feet absorbed and generated more energy at the joints. During different locomotor activities, the contribution of work of the forelimbs changed with both gait and speed. In the stance phase, the metacarpophalangeal joint absorbed more energy than the other two joints while trotting and thus performed better in elastic energy storage. The joint angles changed very little (∼5◦) from 0 to 75% of the stance phase, which reflected the stability of reindeer wrist joints. -
