Neuromuscular function and balance of prepubertal and pubertal blind and sighted boys

2006

Aim: To compare the neuromuscular function and balance of blind prepuberty- and puberty-aged boys to those with normal sight. Methods: Thirty-three prepubertal (aged 9–13 y) and pubertal (aged 15–18 y) blind and sighted boys were tested for muscle mass thickness, electromyography and maximal isometric strength, dynamic explosive actions, and balance. Results: There was no difference in the muscle mass thickness, maximal strength or vertical jump between the blind and sighted boys. However, fitness-ball throwing and five-jump distances were significantly shorter in both blind groups compared to the sighted groups. One-leg stance of the prepuberty-aged sighted boys was 109 (67) s and in blind…

Relationship between Fundamental Motor Skills and Physical Activity in 4-Year-Old Preschool Children

2013

This study evaluated the relationships between objectively measured physical activity and fundamental motor skills in 4-year-old children. Physical activity was monitored in 20 girls and 17 boys over 5 consecutive days (3 days at preschool and 2 days at home) and their fundamental motor skills measured. Multiple linear regressions controlled for sex, age, and body mass index indicated that the total skill score was significantly associated with physical activity, explaining 13%, 16%, and 16% of the variance in total, moderate-to-vigorous, and light-to-vigorous physical activity, respectively. Sliding and galloping were significantly associated with moderate-to-vigorous physical activity, a…

Born to Score? The Relationship between Left-Handedness and Success from the 7-Meter Line

2022

An asymmetry in the prevalence of left-handedness vs. right-handedness in society has supposedly resulted in negative frequency-dependent advantages for left-handers in interactive sports. The aim of this study was to test whether these advantages apply to handball by examining whether being left-handed is beneficial when executing 7 m shots, a highly unimanual movement. All 1,625 7 m shots at the men’s 2016–2022 European championships were analyzed using a Bayesian two-level analysis. While the results did not indicate that left-handers were more likely to score from any single 7 m shot, left-handers were overrepresented among the designated shooters compared to both the population as a wh…

Although the individuality of whole-body movements has been suspected for years, the scientific proof and systematic investigation that individuals possess unique movement patterns did not manifest until the introduction of the criteria of uniqueness and persistence from the field of forensic science. Applying the criteria of uniqueness and persistence to the individuality of motor learning processes requires complex strategies due to the problem of persistence in the learning processes. One approach is to examine the learning process of different movements. For this purpose, it is necessary to differentiate between two components of movement patterns: the individual-specific component and …

The population andresearch sample were all students of class V which numbered 14 students. The test instrumentused to determine is in the form of a pre-test and post-test. Based on the learning outcomes thevalues obtained the average experimental class in t…

The Influence of Fatigue on Throwing and YBT-UQ Performance in Male Adolescent Handball Players

2020

Purpose: The goal of the present study was to assess the effects of fatigue on throwing and Upper Quarter Y Balance Test (YBT-UQ) performance in male adolescent handball players. We hypothesized that throwing and YBT-UQ performance will be decreased in response to an upper-body fatigue-protocol.Method: All male participants (N = 24, age: 14.8 ± 0.7 yrs) were handball players of a regional youth selection team. A radar gun was used for the assessment of throwing velocity. The YBT-UQ was executed assessing medial, inferolateral and superolateral reach directions normalized to the upper limb length together with a composite score. Immediately following a fatigue protocol of different sets of p…

Evaluation of Explosive Strength for Young and Adult Athletes

1988

Abstract The explosive strengths of young (n = 361) and adult (n = 10) male athletes were evaluated by a vertical jumping and a ball-throwing test. The young athletes ranged in age from 10 to 16 years representing seven different sports events: track and field, apparatus gymnastics, basketball, ice hockey, orienteering, skiing, and wrestling. The adult subjects were volleyball players. Weighted vertical counter-movement jumps were performed on a platform connected to an electronic unit which calculated the height of the rise of the body's center of gravity. For the stationary ball throwing test, horizontal throwing velocity was measured for balls of different masses by an electrical apparat…

“Throwing into the Whirlwind Vortex”: Unaccounted Memoirs about Blok by S. Korenev

2021

The article examines certain plots of the “Blok theme” in the 1920s Riga periodicals, which had not previously attracted the attention of researchers. The Russian press of independent Latvia (1919 –1940) has preserved many tens, if not hundreds, of articles, correspondences, documents, poetic texts dedicated to A.A. Blok’s personality and works. Among them are memoirs of people who were familiar with the poet, met with him, listened to his speeches. However, most of these scattered memoirs remain forgotten and are not taken into account in the Blok studies. The author recalls the texts of V.V. Tretyakov, A.M. Perfiliev and republishes from the Riga newspaper “Slovo” a memorial article about…

The effects of instructional self-talk on quiet eye duration and golf putting performance

2017

Yonatan Sarig, 2017. The Effects of Instructional Self-Talk on Quiet Eye Duration and Performance. Faculty of Sports and Health Science. University of Jyväskylä. Master’s thesis, 63p. While the literature on the effects of instructional self-talk is comprehensive, a somewhat under-investigated subject is the underlying mechanisms of instructional self-talk. As of late, the trend has been shifted towards researching what are the motivational and attentional constructs at the base of self-talk. Potentially, one such attentional construct is the quiet eye; the final gaze fixation on a target before the execution of task-oriented movement. Since the duration of the quiet eye is found to be asso…

Injury and Throwing Distance in Teenage Cyclist- Vehicle Crash

2016

The study of the injury caused by vehicle-teenage cyclist crash is presented in this paper. The results of the crash with three vehicles: sedan, SUV and Pick up are compared. Three different positions are analyzed: front, rear and lateral position. The injury on the cyclist head is examined by HIC criterion, in the way indicated by the rules. A comparison is done between the results of the simulations for Pick up, SUV and sedan, concluding that the injury of the head is more dangerous for Pick-up impact than SUV or the sedan, but only at greater speed than 40 km/h. Teenage cyclist is more likely to suffer an injury to the chest in rear impacts with the sedan, because 3 ms values remain abov…
