The present study examined stride pattern characteristics of Class F11 visually impaired long jumpers and triple jumpers. Athletes demonstrated initial ascending footfall variability followed by descending variability, on the second (long jumpers) and third (triple jumpers) stride prior to take-off, at a mean distance of 6.26 m (long jumpers) and 7.36 m (triple jumpers) from the take-off board. Toe-board-distance variability reached a maximum value of 0.36 m and 0.38 m for the long and triple jump, respectively. Last stride toe-board-distance variability was 0.29 m (long jump) and 0.25 m (triple jump). Class F11 visually impaired athletes exhibit regulation of goal-directed gait analogous to that of non-visually impaired athletes.
"The validity of the procedure for calculating the toe–board distance was assessed by recording running shoes placed at known distances along the runway (Scott et al., 1997; Theodorou & Skordilis, 2012). The running shoes were placed at distances from the front edge of the take-off board of 0.10 m, 1.0 m, 2.0 m, 3.0 m, 5.0 m and thereon in 2 m intervals up to 25.0 m, so as to cover the whole range of the recorded field.

[Show abstract][Hide abstract] ABSTRACT: Abstract We examine the presence of visually regulated control in young, novice long jumpers as they approach the takeoff board. The approach run of 27 novice jumpers (age 12-13 years) practising jump training for a short period was video-recorded during competition. Findings revealed that young, novice participants adjust the length of the final steps of their approach run, suggesting the presence of visual control. Step regulation commenced on the fifth and fourth step from the board for boys and girls respectively. Their pattern of footfall variability was found to be comparable to that of skilled long jumpers, although young, novice participants presented slightly higher variability. It appears that even a limited period of jump training may contribute to a more consistent run-up as well as to smaller takeoff error, offsetting the limitations imposed by the partially developed cognitive abilities and perceptual awareness of young athletes.
[Show abstract][Hide abstract] ABSTRACT: The purpose of the study was to investigate the occurrence of stride regulation at the approach phase of the long jump in athletes with normal vision and visually deprived Class F12 and F13 athletes. All the athletes exhibited the presence of a regulatory mechanism. In the normal vision group this occurred on the fifth-to-last stride. In Class F12 athletes regulation commenced on the fourth-to-last stride for males and third-to-last stride for females. Class F13 males commenced regulation, like the control group, on the fifth-to-last stride; but females commenced on the fourth-to-last stride. The study demonstrated that reduced vision does not prevent Class F12 and F13 athletes from applying a regulatory mechanism similar to that observed in sighted athletes. However, the control mechanism of regulation emerged earlier in non-visually deprived long jumpers and the least visually impaired Class F13 athletes, signifying the importance of visual function in the regulatory stimuli.

[Show abstract][Hide abstract] ABSTRACT: Purpose: to justify the use of a new technique for complex Bodyflex and Pilates using information and
communication technologies. Material: the study involved 46 students. Conducted teacher testing: lean body
forward from a sitting position ( flexibility test ), shuttle run, standing long jump seats, running 100m, lifting the body from a prone position in the saddle (the number of times for 1 min), flexionextension in the hands of the emphasis lying, running 2000 and 3000m. Results: the effect of the integrated application of this technique to the level of physical fitness of students. A system for applying the Bodyflex Pilates and using information and communication technologies. The system consists of the author’s modification Bodyflex and Pilates, and use their mutual coupling copyright information technology. Internet blog created as a social group called “Sport and motivation” In a blog posted motivational pictures, practical tips for healthy and dietetic nutrition, information on healthy lifestyle, music for workouts. The blog highlights some fitness techniques open threads
(discussion ) for on-line communication between users. A significant increase in the results of educational tests of physical fitness among students. Conclusions: the technique of complex applications Bodyflex and Pilates using information and communication technologies has shown a positive effect of complex application of this technique to the level of physical fitness of students.
