The Relationship

Background: ‪Despite having similar requirements to regular football, amputee football may also require different dynamics due to using crutches. This study investigated the relationship between upper extremity strength and performance in amputee players. Material and methods: ‪Twenty amputee players participated in this study. Running performance of amputee players was measured with sprint tests; aerobic performance with a shuttle run test; jumping performance with a one-leg hop test and upper extremity strength with a digital dynamometer. The relationship between the types of performance was evaluated by multiple regression analysis. Results: T‪he 10 (p = 0.009) and 20 meters sprint performance (p = 0.035) was associated with latissimus dorsi muscle and the 30 meters (p=0.030) with shoulder extension strength. In addition, 10 (p = 0.018), 20 (p = 0.020) and 30 meters sprint performance (p=0.036) was associated with one-leg hop performance. However, there were no related data with the max VO2 (p = 0.339), and the aerobic performance test duration (p = 0.348). Conclusions: ‪The results indicated that the sprinting performance of amputee players was not only related with lower extremity strength but also with upper extremity strength. It may be beneficial to include shoulder extension and particularly latissimus dorsi strengthening exercises in training programs of amputee football players to provide an increase in anaerobic performance.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

The Relationship

Background and Study Aim. Sprint performance plays a major role in success of field-based team sports such as soccer. The aim of this study was to evaluate the relationship between sprinting performance and both lower and upper extremity explosive strength in young soccer players. Material and Methods. One hundred forty-seven soccer players (mean±SD; age 11.6±1.66 years, height 143.2±11.8 cm, body mass 37.1±10.2 kg and training experience 1.11±1.5 years) voluntarily participated in this study. The sprinting performance of each player was determined using their 5, 10, 20 and 30m single sprint times. The lower and upper extremity explosive strength were evaluated by standing long jump and medicine ball throwing tests respectively. Prior to the study, each of the players was given detailed information about the risks and injuries they could encounter during the study, and parental consent was obtained by their signatures on informed voluntary consent forms since the subjects were under the age of 18. Permission to conduct the study was obtained from Ankara University Medical Faculty’s Surgical and Medical Research Ethics Committee. Results. The results indicated a strong relationship between sprinting performance and horizontal jump performance (r=-.671 ̶ -.764; p=0.001) and also a large relationship between sprinting performance and upper extremity strength (r=-.633  ̶  -.703; p=0.001). The sprint performance (n=147) also significantly correlated with body weight (r=-.345  ̶  -.373; p=0.001) and height (r=-.445  ̶  -.505; p=0.001). Conclusions. The study results suggest that upper extremity strength is as important as the lower extremity strength for sprinting performance and that trainers should emphasize lower and upper extremity strength in training intended to improve sprinting performance.

Abstract Background Physical function limitations precede disability and are a target to prevent or delay disability in aging adults. The objective of this article was to assess the relationship between self-report and performance-based measures of physical function with disability. Methods Baseline data (2012–2015) from the Canadian Longitudinal Study on Aging (n = 51,338) was used. Disability was defined as having a limitation for at least one of 14 activities of daily living. Physical function was measured using 14 questions across three domains (upper body, lower body, and dexterity) and five performance-based tests (gait speed, timed up and go, single leg stance, chair rise, and grip strength). Logistic regression was used to assess the relationship between physical function operationalized as (i) at least one limitation, (ii) presence or absence of limitations in each individual domain/test, and (iii) number of domains/tests with limitations, with disability. Results In the 21,241 participants with self-reported function data, the odds of disability were 1.87 (95% CI: 1.56–2.24), 6.78 (5.68–8.08), and 14.43 (11.50–18.1) for one, two, and three limited domains, respectively. In the 30,097 participants with performance-based measures of function, the odds of disability ranged from 1.53 (1.33–1.76) for one test limited to 14.91 (11.56–19.26) for all five tests limited. Conclusions Both performance-based and self-report measures of physical function were associated with disability. Each domain and performance test remained associated with disability after adjustment for the other domains and tests. Disability risk was higher when the number of self-report domains and performance-based limitations increased.

Benign childhood epilepsy with centro-temporal spikes (BECTS) is a form of epilepsy with no demonstrable anatomical lesion showing spontaneous seizure remission. During the active phase of the disease the children may show cognitive deficits. The objective of this study was to assess, in children with BECTS, the relationship between clinical-EEG aspects and performance in the school performance test (SPT), Raven's progressive matrixes test and the Wechsler Intelligence Scale for Children (WISC-III). Forty-two 7 to 11 year old children were included and the following tests carried out: anamnesis, neurological examination, electroencephalogram (EEG), SPT, Raven's test and WISC-III. The children with BECTS had normal IQ values but showed inferior performance in the SPT more frequently than "healthy" children, paired with respect to age and maternal scholastic level. There was moderate positive correlation between WISC-III results and the age when the seizures started and the educational level of the parents. On the other hand, aspects linked to the epileptic nature of BECTS, such as the number of seizures, time since last seizure and the number and lateralization of the centro-temporal spikes on the EEG, showed no correlation with the neuropsychological tests.

This study was conducted to determine optimum test duration for measuring performance, feed intake and feed efficiency. Sixty young Nellore bulls were submitted to feeding performance test and fed in individual pens to determine feed intake and performance over 112 days. Body weight was determined every 28 days, after fasting of water and feed for 16 hours. Changes in variance, relative variance and Pearson and Spearman correlations among data from shortened test periods (28, 56 and 84 days) and full test period (112 days) were used to determine optimum test duration. Test duration for average daily gain, dry matter intake, feed:gain ratio and residual feed intake could be shortened to 84, 28, 84 and 84 days, respectively, without reducing significantly the reliability of measurements for animals fed in individual pens.

The Relationship

Background: Understanding the relationship between perceived fatigue and performance fatigability could lead to more effective interventions to manage multiple sclerosis (MS)–related fatigue. However, the relationship between self-perceived fatigue measured using the Neurological Fatigue Index (NFI-MS) and performance fatigability in people with MS is unknown. We sought to explore the relationship between the NFI-MS and performance fatigability in people with MS. Methods: Fifty-two participants (mean ± SD age, 46.8 ± 10.1 years) completed the study. Three measures of performance fatigability were used: percent change in meters walked from first to last minute of the 6-Minute Walk Test, percent change in force exerted from first to last trial on a repetitive maximal hand grip test, and response speed variability on the Continuous Performance Test. Perceived physical and cognitive fatigue were measured using the NFI-MS. The state level of fatigue was examined immediately before and after performing the fatigability measures using a one-item visual analogue fatigue scale. Results: Of the three performance fatigability measures, only the attentional task (response speed variability) was significantly associated with NFI-MS physical (r = 0.326, P = .020) and cognitive (r = 0.276, P = .050) domain scores. Participants demonstrated significantly higher state levels of fatigue after performing all performance fatigability measures (P ≤ .001). Conclusions: The NFI-MS and the performance fatigability measures used in this study are easy to administer. We encourage wider use of these measures in clinical and research settings for comprehensive assessment of MS-related fatigue.

The main aim of this research was to determine to which degree the system of variables used to evaluate specific motor skills correlated with the system of variables used to evaluate successful performance in football play. The study was conducted on a sample of 170 senior football players. There were 16 predictor variables to assess specific motor skills and eight criterion variables to assess successful performance. A canonical correlation analysis was applied in the statistical procedure to determine the relationships (correlations) between these spaces. Correlations were established between the investigated spaces with four pairs of canonical factors, and it has been shown that situational motor skills have high correlations with performance success in the game of football (Can R.=0.71, on average). It is indicated that the participants whose performance in football play was more successful also had better situational motor skills and that the mechanism for structuring movement is shown to be of great importance for the successful performance of tactical and technical elements in football players.

Abstract. The study covered 11 376 horses registered in the six successive volumes of the Wielkopolski Herdbook. The level of variability in the body conformation indices and in the performance value indices was analysed. The genetic basis parameters for the body conformation and performance traits of the Wielkopolski horses were assessed. A high level of heritability was identified for the wither height (h2 = 0.566) and cannon circumference (h2 = 0.418), with an average heritability level of the other analysed characteristics (ranging from h2 = 0.205 – for the stallion performance test results to h2 = 0.350 – in the case of chest circumference). On the other hand, genetic correlation between the analysed indices produced the highest values for the relationship between wither height and cannon (rG = 0.636) and chest (rG = 0.551) circumference, as well as for the interrelation between the above dimensions and the following body structure indices: »boniness« (rG = 0.690) and »bulkiness« (rG = 0.541). Considering the extensive scope of the study – and the fact that the breed population was registered in the Wielkopolski Herdbook – the authors suggested the advisability of using the results of the present study for the modification of breeding programs with a view to improve the breed in question, both its principal population and the one included in the program of gene-pool protection.

The existing paper deals with a primary objective; to examine the relationship between hockey coaches and performance of field hockey players in socio-interaction approach. The secondary objective was to measure the field performance of hockey players on practical measures. The research methodology is based on both descriptive and inferential statistical approaches. The descriptive data was collected in the form of field performance tests (technical skills and fitness capabilities) while the inferential data perceived by players was collected using survey questionnaire. Adopted field performance test measures and survey questionnaire were employed. 296 national field hockey players of Pakistan were selected from national departments of field hockey as samples. The field performance tests and the relationship were analyzed using descriptive statistics and Pearson’s correlation analysis respectively. The results of the field performance tests were found below than average (weaker) in technical skills and fitness capabilities. However, the findings of the inferential analysis revealed that all constructs of hockey coaches have significant positive relationship with all variables of performance of field hockey players. The significance level was found at the 0.01 (2-tailed).
