Abstract

Relationships between performance scores in reading achievement, Frostig Developmental Test of Visual Perception, Lincoln-Oseretsky Motor Development Scale, two perceptual-motor tasks and eye-hand dominance tests were studied in 75 first and second grade children. Correlations among many variables were significant although none were high enough for reliable prediction of one variable from another. Mixed eye-hand dominance was not found to be associated with deficient performance in any of the tests. Factor analysis failed to provide factors indicative of interrelationships among elements of visual, motor, and reading functions.  相似文献

Abstract

The study was designed to determine the relationships between achievement in reading and achievement in selected motor skills for children in grades 1, 3, 5. The Iowa tests of basic skills were used to determine reading achievement and the Johnson motor achievement battery was employed to measure achievement in selected motor skills. The Pearson product-moment coefficient of correlation was applied to compute the relationships between the reading and motor achievement variables. The subjects were divided into three reading achievement levels and Scheffe's method of comparing pairs of means from a two-way analysis of variance table was employed to determine if the achievement differences in the motor skills tests were significant. The following conclusions were drawn: a) Highly significant correlations were found to exist between achievement in reading and the throw and catch test and achievement in reading and the zig-zag run test; b) Little or no consistent relationship existed between achievement in reading and the kicking test or the jump and reach test; c) Significant differences among the selected reading levels were found for the throw and catch test and the zig-zag run test; d) Few significant differences among the selected reading levels were found for the kicking test and for the jump and reach test.  相似文献

Abstract

Near-infrared spectroscopy is currently used to assess changes in the oxygen saturation of the muscle during exercise. The primary purpose of this study was to assess the reliability of near-infrared spectroscopy in determining muscle oxygen saturation (StO2) in the vastus lateralis during cycling and the gastrocnemius during running for exercise intensities at lactate threshold and maximal effort. Test-retest reliability was determined from an intraclass correlation coefficient obtained from a one-way analysis of variance. Reliability of muscle StO2 for the gastrocnemius at lactate threshold was R = .87, and R= .88 at maximal effort. Reliability of muscle StO2 for the vastus lateralis at lactate threshold was R= .94 and R = .99 at maximal effort.  相似文献

Abstract

This study compared the effects of mobility patterning techniques to the effects of special physical education activities upon selected motor skills of primary school educable mentally retarded children. The experimental group received the appropriate mobility patterns in creeping, crawling, and walking, which later were practiced in game situations. The control group received special physical education activities. Both groups received daily 30-minute classes, Monday through Friday, from September 1966 to December 1966. Based on the differences in leg power as measured by the hurdle jump and the standing broad jump, it appeared that the special physical education activities contributed more to the development of the subjects. However, neither program was more effective than the other in terms of dynamic balance, agility, or fine manual motor coordination.  相似文献

高水平运动技能训练中的运动知觉心理训练取向   总被引:6,自引:3,他引:6  
针对目前高水平运动技能训练中解决细节问题时缺乏具体操作方法的现状,试图通过基础理论及运动专门化知觉训练范式的分析,以引起教练员对运动技能心理训练的重视。研究提出,应该重视心理训练在运动技能训练中的作用,心理训练不仅仅只是情绪管理,它还担负增强动作技能认知复述的任务;正确的运动知觉是运动反应的前提,专门化知觉训练是运动技能训练方法的取向;高水平运动技能训练中求质比求量更重要,破坏动力定型或认知结构的练习宁肯不做;建立科学的感知觉定位系统并结合有效反馈控制手段是操作策略;遮蔽、表象、反馈和量化控制等是技能细化的具体方法。  相似文献

Purpose: This study aimed to investigate the relationship between fundamental movement skills (FMS) and markers of health among a cohort of Irish primary school children. Methods: Participants (N = 296, mean age: 7.99 ± 2.02 years) were senior infant (n = 149, mean age: 6.02 ± 0.39 years) and 4th class (n = 147, mean age: 9.97 ± 0.40 years) students from three primary schools in Cork, Ireland. FMS proficiency (TGMD-2) and markers of health (BMI percentile, waist circumference percentile, blood pressure percentiles, resting heart rate, cardiorespiratory fitness, objectively measured physical activity; PA) measurements were recorded. Correlation and hierarchical stepwise multiple linear regression analyses were conducted to investigate the relationship between FMS and markers of health. Results: A small, positive relationship was found between FMS (Gross Motor Quotient; GMQ) and cardiorespiratory fitness with small negative correlations between GMQ and 550 m time SDS among 6-year-olds (r(129) = ?.286, p < .05) and 10-year-olds (r(132) = ?.340, p < .05). A moderate, positive correlation was found between GMQ and light PA (r(71) = .400, p < .05). Small positive correlations were revealed between GMQ and moderate PA (r(71) = .259, p < .05) and between GMQ and total PA (r(71) = .355, p < .05). After adjusting for age, sex, the interaction effect of age and sex, and school attended, FMS explained 15.9% and 24.8% of the variance in 550 m time SDS among 6- and 10-year-olds, respectively, and 6% and 6.5% of the variance in light PA and moderate PA, respectively. After adjusting for age and sex, FMS explained 11.6% of the variance in total PA. Conclusion: A wide range of FMS is important for children’s cardiorespiratory fitness and PA.  相似文献

Abstract

The purpose of this study was to examine the relationship between motor proficiency and body mass index (BMI) in preschool children. Thirty-eight children ages 4–6 years had their BMI calculated and were assessed using the Movement Assessment Battery for Children-2 (MABC-2; Henderson, Sugden, & Barnett, 2007). These data were analyzed in two ways. The correlation between BMI and MABC-2 percentile ranks was calculated. Next, the groups were subdivided based on BMI status (high, M = 85.5; medium, M = 49.8; low, M = 10.8), and compared using t tests to determine if differences existed in MABC-2 percentile ranks. No significant relationship existed between MABC-2 and BMI percentile ranks (r = -.237). However, significant differences in MABC-2 percentile ranks existed between high and low (p = .042), and high and medium (p = .043) groups. These results suggest that preschool children classified as overweight or obese may have lower motor proficiency than their normal weight and under weight peers. This study indicates there is a direct relationship between motor proficiency and BMI in the preschool population.  相似文献

Abstract

The caloric intake and physical activity patterns of 50 fifth grade students were studied to determine the relative contributions of diet and physical inactivity in the development of obesity. On the basis of tricep skinfold measurements, the subjects were divided into four groups or levels of obesity. Seven-day diet recall records were then obtained with the cooperation of the children's parents. Activity patterns were studied by filming the subjects during games of high and low organization and during free play. Indexes of the duration and intensity of activity were derived from the film analysis. The caloric intake and physical activity patterns of the four groups were compared by the Duncan Multiple Range Test. Using the combined scores for all groups, correlation coefficients were computed to determine the relationship between (1) skinfold measures and total caloric intake, (2) skinfold measures and activity patterns, and (3) total caloric intake and activity patterns. The relative inactivity of the obese children and the relatively similar diets of all children regardless of body fat, as well as the significant negative relationship between activity indexes and body fat tended to support the contention that inactivity may be as important or more important than excessive caloric intake in the development and maintenance of childhood obesity.  相似文献

Abstract

The ability of 48 college women to adjust hand-eye coordination in a rearranged visual field was compared with ability to learn a new motor skill and with present level of motor ability. The measuring instruments utilized included the Scott motor ability test, Moody's new motor skill learning test, and a variation of the mirror-box test of Held and Gottlieb. Subjects were exposed for one minute to each of four experimental treatments—moving chessmen and throwing a ball performed both while wearing prism-glasses and without wearing these glasses. Subjects received one treatment per day, two days per week; the treatments were repeated in the same order and sequence, making a total of eight experimental sessions. The findings did not justify the conclusion that a relationship exists between motor ability or new motor skill learning and ability to adjust to a rearranged visual field. Wearing prism-glasses did not result in a consistent amount of visual rearrangement with each subject.  相似文献

Abstract

The purpose of this study was to investigate the factor structure of the sports skill domain of basketball and to identify test items to measure in this skill domain. A theoretical model of the hypothesized dimensions of basketball playing ability was developed based on a review of literature concerning basketball skill testing from 1906 to the present day. These dimensions were: (a) shooting, (b) passing, (c) jumping, (d) movement without the ball and (e) movement with the ball. Twenty-one items, including the nine items in the AAHPER basketball skill test for boys, were selected to sample these hypothesized dimensions. The tests were administered to 70 male junior high and high school students enrolled in the University of Minnesota, Duluth basketball camp during the summer of 1975. The hypothesized dimensions were analyzed by use of the following: (a) alpha factor analysis; (b) canonical factor analysis; (c) image analysis; and (d) principal components analysis. Both oblique and orthogonal rotations were performed with each of the four analyses. The hypothesized model was partially substantiated in that the results confirmed three of the factors: (a) shooting, (b) passing and (c) jumping with the only difference being that the factors of movement with the ball and movement without the ball combined into one. Since the following test items best represented the dimensions, it appeared that a battery comprised of these items would provide a quick and objective measure of basketball skill: (a) jump and reach, (b) dribble, (c) speed pass, and (d) front shot.  相似文献

Abstract

Nineteen college men and women (aged 18–23 yrs, × = 21.1) were studied to ascertain the force-time components of a rapid maximal voluntary isometric contraction (MVC) for ankle dorsiflexors, knee extensors, elbow flexors, wrist flexors and hand grip. Standardized isometric strength testing protocol was used. After a practice period subjects were instructed to make an MVC without jerking and as quickly as possible, for each of the muscle actions noted above. Force readings were taken from a load cell assembly through an analogue-to-digital converter and analyzed to yield time values for MVC, 3/4 MVC, 1/2 MVC, and 1/4 MVC. The results indicated significant differences (p < .01) between the responses of the men and women, with the women reaching full MVC more rapidly than the men. Also, there were significant differences among the five muscle groups tested, with the wrist flexor muscle group developing MVC most quickly, while the knee extensors took the longest time to full MVC. Based upon these data it may be concluded that the time to full MVC differs between men and women, and also that the time to full MVC differs among the five muscle groups tested in this experiment.  相似文献

Abstract

The purpose of this study was to determine the effects of variable decision-making teaching models upon the development of body coordination and self-concept of children in grades one through five. Students in two socioeconomically equivalent schools of a large, inner-city school system constituted the sample (N = 285) for this study. Intact classroom groups from the experimental school were randomly assigned to one of two experimental treatments. The control school did not receive any treatment. The experimental treatments consisted of two physical education programs which varied only in the type of teacher behavior exhibited. Cheffers' Adaptation of Flanders' Interaction Analysis System (Cheffers, Mancini, & Marlinek, 1980) was used to verify the two treatments used. The Schilling Body Coordination Test (Schilling & Kephart, 1976) was used to evaluate motor skill development, and the Marlinek-Zaichkowsky Self-Concept Scale (1977) was used to evaluate self-concept development. Results indicated that learners can be given decision-making responsibility within the physical education environment and, at the same time, maintain a level of motor skill achievement equal to that of learners who have not been allowed to make decisions within the learning environment. No conclusions could be drawn concerning the effects of student decision making upon self-concept development. Additional results indicated that the development of body coordination is a function of maturation, and that no relationship exists between self-concept and body coordination.  相似文献

We recently published an article on arm coordination and performance level in 400-m front-crawl swimming in Research Quarterly for Exercise and Sport (Schnitzler, Seifert, &; Chollet, 2011). The index of coordination (IdC) was used to quantify interarm coordination. Our results showed that expert swimmers exhibited lower IdC than recreational swimmers over a 400-m trial. In addition to criticizing various methodological points, Havriluk (2012) challenged our conclusion that catch-up could be an efficient model of coordination and instead suggested that it might lead to injuries. An important point in this debate, however, is that our definition of catch-up coordination may differ from the one proposed by Havriluk (2012), which would explain why we consider catch-up coordination to be the dominant mode of coordination used by expert swimmers during training sessions.  相似文献

Abstract

Self-control over factors involving task-related information (e.g., feedback) can enhance motor learning. It is unknown if these benefits extend to manipulations that do not directly affect such information. The purpose of this study was to determine if self-control over the amount of practice would also facilitate learning. Participants learned to throw a dart using their nonpreferred hand. The self-control (SC) group decided when to stop practice. The yoked group completed the same number of trials as their SC counterparts. Results revealed the SC group was more accurate during transfer and in recalling the number of trials completed. These findings indicate that self-control benefits extend to factors that do not directly alter task-related information.  相似文献

Abstract

This study was conducted for the purpose of determining the relationship between specific factors of personality adjustment and levels of motor achievement in a select group of junior and senior high school boys. Pertinent scales from the 16 Personality Factor Questionnaire and the Guilford Zimmerman Temperament Survey were administered to 154 subjects for the purpose of determining existing personality characteristics. The motor achievement data were collected from administration of the McCloy General Motor Ability and Motor Capacity Test. The data were statistically analyzed through the use of the Pearson product-moment correlation technique, the t test, and the multiple regression technique. The study concluded that, (a) individual group dependance was a factor in extent of exhibited motor achievement and, (b) that levels of motor achievement were predictable with the use of grouped measured personality characteristics.  相似文献
