movimiento que lo hacen apto para el trabajo en hipoterapia.In the present study a description of some basic conformational and biokinematic characteristics of 16 mares that belong to the breed Caballo Fino Chilote was conduce, at the hand-led walk. The objective was to determine some conformational and biokinematic characteristics at the hand led walk for 16 mares and the possible aptitudes, of this breed, for being used as a therapeutic tool in hipotherapy activities. The conformational parameters were measured in vivo using a metric tape and ruler. For the time-related and biokinematic parameters, a 10m curtain graduated every 50 cm was specially made, in front of which each mare was guided at a hand-led walk while being filmed with a Sony Hi-8 camera. The video was transformed into photos using the Final Cut programme; 15 frames per second were obtained in JPG format; the frames were then passed into TIFF to measure the angular parameters with the help of the Scion Image programme. Lineal parameters were directly measured from the video using a Sony flat screen television. All data analysis was conducted with descriptive statistics using Microsoft Excel xp. The means obtained for conformational parameters were: height at the withers 117.94 cm (± 2.6, height at the back 113.3 cm (± 2.1, and height at the hindquarters 119.9 cm (± 3.1. For the lineal parameters the mean stride length was 135.3 cm (± 8.9 and the mean step length was 69.3 cm (± 5.8. The mean stride duration was 1.18 seconds giving a mean speed of 114.7 cm/sec. The angular parameters of the limbs were measured for the shoulder, elbow and carpus joints in the forelimb and for the hip, stifle and tarsus joints in the hindlimb, also the scapula and pelvis inclination were measured obtaining curves for each one along a complete stride cycle, and angular range of motion was determined.
Se realizó una descripción de ciertas variables conformacionales y biocinemáticas básicas, al paso guiado a mano, en 16 yeguas de la raza Caballo Fino Chilote. Las variables conformacionales se midieron en vivo con el uso de huincha métrica y bastón hipométrico. Para obtener las variables biocinemáticas y de tiempo se utilizó un telón, frente al cual se hizo pasar al paso guiado a mano a las 16 yeguas, mientras eran filmadas con una cámara de video Sony Hi-8. El video fue transformado a fotog...
Full Text Available The features of technical preparedness are studied in the jerk of highly qualified female weightlifters with different body mass according to somatotype. The model values of spatiotemporal indices of motion structure in the jerk are determined. The analysis is conducted and differences are exposed in the biokinematics motion structure in competition exercise «jerk» of female athletes taking into account anthropometric indices in the different weight categories groups. In research took part the 116 strongest female weightlifters of the world.
Full Text Available Aggregate data are expounded about methodical approaches at the modeling of technique of motor actions in sport. Practical material is presented on questions of design and perfection of technique of motor actions on the example of different types of sport. The model of technique of running step is offered on a line in short-track. A cross-correlation analysis between resulting speed of general centre-of-mass body of sportsmen and biomechanics descriptions exposed six important indexes. These indexes are plugged in a statistical model at run on a line. It is set that on the initial stages of preparation of sportsmen it is necessary to take into account the biokinematics and biodynamic structure of technique of motive actions.
Full Text Available Purpose: the biomechanical analysis of execution of upward jump piked. Material & Methods: the following methods of the research were used: theoretical analysis and synthesis of data of special scientific and methodical literature; photographing, video filming, biomechanical computer analysis, pedagogical observation. Students (n=8 of the chair of national choreography of the department of choreographic art of Kiev national university of culture and art took part in carrying out the biomechanical analysis of execution of upward jump piked. Results: the biomechanical analysis of execution of upward jump piked is carried out, the kinematic characteristics (way, speed, acceleration, effort of the general center of weight (GCW and center of weight (CW of biolinks of body of the executor are received (feet, shins, hips, shoulder, forearm, hands. Biokinematic models (phases are constructed. Power characteristics are defined – mechanical work and kinetic energy of links of legs and hands at execution of upward jump piked. Conclusions: it is established that the technique of execution of upward jump piked considerably influences the level of technical training of the qualified sportsmen in gymnastics (sports, in aerobic gymnastics (aerobics, diving and dancing sports.
