AbstractThis study aimed to investigate the relationship between mechanical parameters from the Running-based Anaerobic Sprint Test (RAST2×17.5), agility performance from the Illinois Agility Test (IAT) and all-out 30-second tethered running (AO30) in college futsal athletes. It also investigates whether these protocols are capable of identifying differences between sexes. Twenty subjects were evaluated. The IAT was applied on a specific course and performance was considered as the total time (T.T). The RAST2×17.5 consisted of six maximum efforts in a shuttle exercise of 2x17.5 m per bout. The AO30 was conducted under maximal effort on a non-motorized treadmill. Maximum, mean and minimum power were determined for RAST2×17.5 and AO30. Mean power from RAST2×17.5 was inversely and significantly correlated to T.T regardless of sex (male: r=–0.76; p=0.010; female: r=–0.89; p=0.010). A similar association was noticed for maximum power for females (r=–0.94; p=0.001). The AO30 maximum and mean power were significantly correlated with T.T (male: r=–0.67; p=0.031 and r=–0.66; p=0.035, respectively; female: r=–0.64; p=0.046 and r=0.66; p=0.035, respectively). Maximum power from RAST2×17.5 and AO30 were significantly correlated (male: r=0.68; p=0.030; female: r=0.72; p=0.019). Our results reinforce the adoption of field-based tests like RAST2×17.5 and IAT for futsal, since significant relationships among these parameters and AO30 results were obtained. Moreover, these protocols differentiated male and female athletes by mechanical and agility parameters, proving their application under specific field evaluation.

Musculotendinous Stiffness

The purpose of this study was to quantify the relationship between musculotendinous stiffness and performance in eccentric, isometric, and concentric activities. Thirteen trained subjects performed a series of maximal effort eccentric, concentric, and isometric muscular contractions in a bench press-type movement. Additionally, subjects performed a series of quasi-static muscular contractions in a bench press movement. A brief perturbation was applied to the bar while these isometric efforts were maintained, and the resulting damped oscillations provided data pertaining to each subject's musculotendinous stiffness. Musculotendinous stiffness was significantly related to isometric and concentric performance (r = 0.57–0.78) but not to eccentric performance. These results are interpreted as demonstrating that the optimal musculotendinous stiffness for maximum concentric and isometric activities was toward the stiff end of the elasticity continuum. A stiffer musculotendinous unit may facilitate such performances by improving the force production capabilities of the contractile component, due to a combination of improved length and rate of shortening, and additionally by enhancing initial force transmission.

This exploratory study examined the relationship of perfectionism (from a recently devised multidimensional measure) with female athletes' reactions to athletic competition and coaches' ratings of reactions to mistakes during competition. Athletes who rated high in Concern Over Mistakes (one dimension of perfectionism) reported more anxiety and less self-confidence in sports, displayed a general failure orientation toward sports, reacted negatively to mistakes (by their report and by coaches' ratings), and reported more negative thinking in the 24 hours prior to competition. A second dimension of perfectionism, High Personal Standards, was associated with a success orientation toward sports and more dreams of perfection prior to competition. The possible influence of perfectionism on motivation and performance in sports is discussed.

Abstract Introduction. The aim of this article is to discuss the relationship between affective states experienced by athletes and the outcome of their performance. The article presents the findings of a pilot study which made it possible to determine the relationship between the emotional states, mood, and level of stress of a group of pentathletes and the outcomes they achieved in a sports competition. Material and methods. The study involved 12 senior modern pentathletes, including 7 male and 5 female athletes. The following standard psychology questionnaires were used in the study: the 10-item Perceived Stress Scale (PSS-10), the Positive and Negative Affect Schedule (PANAS), and the Profile of Mood State (POMS). Performance was assessed based on the number of points achieved by the pentathletes in particular events in the pentathlon, which are held according to the rules set by the International Modern Pentathlon Union (UIPM). Results. The findings of the study confirmed that there was a correlation between the athletes’ mood and emotions and the outcome of their performance. The level of stress strongly negatively correlated with both the outcome they expected to achieve and the one they actually achieved for the combined event (running and shooting). For this event a relationship was also found between the athletes’ affective states and their outcomes: in running and shooting there was a positive and statistically significant correlation between the level of positive emotions and anger and the results achieved. However, friendliness, one of the other affective state variables that were measured, correlated negatively with the outcomes of the athletes’ performance. Conclusions. In the group of pentathletes who participated in the study, a high level of anger was associated with better outcomes, and a high level of friendliness had an adverse effect on the results achieved. The findings of the current study confirm that there is a relationship between affective states and performance outcomes, but the findings do not correspond with Morgan’s iceberg profile.

In Sri Lanka especially in Batticaloa, the studies related to dynamic capabilities, organizational inertia and organizational performance are rare and there is need to fill this empirical gap by investigating the influence of the dynamic capabilities of small and medium enterprises (SMEs) on organizational performance, and the interaction between dynamic capabilities and organizational inertia in a volatile environment. Therefore, this study has been undertaken to examine the relationship among these three variables and to assess the moderating role of organizational inertia in relationship between dynamic capabilities and organizational performance. The findings indicated that the variables have significant relationships among them and further findings of this study revealed that organizational inertia negatively moderates the relationship between dynamic capabilities and organizational performance of SMEs in Manmunai North Divisional Secretariat in Batticaloa District. By addressing the findings of this study SME owners could try to reduce the inertia in their business by which the relationship between dynamic capabilities and performance can be induced and this lead the businesses in achieving competitive advantages.

The Relationship

Based on Barter's competence motivation theory, this study examined the relationships between perceived coaching behaviors and (a) perceptions of ability and (b) motivation in competitive age-group swimmers. Male and female athletes (N=312) assessed their coaches' behaviors and their own ability and motivation using self-report measures. Multivariate analyses indicated that significant relationships were found for males, females, 12–14-year-olds, and 15-18-year-olds. Variables contributing most importantly to the relationships differed depending upon gender and age group. In general, coaches who were perceived as giving more frequent information following desirable performances, and more frequent encouragement combined with information following undesirable performances, were associated with athletes who perceived higher levels of success, competence, enjoyment, and preference for optimally challenging activities. These results indicate that young athletes' self-perceptions and motivation are significantly related to the quantity and quality of coaching feedback they receive for performance successes and errors.

For steep slopes with difficult access or slopes in a corrosive environment, there are various problems associated with the use of conventional steel reinforcement bars as soil nails. For loose-fill slopes or clay slopes, the development of adequate nail bond strength is another practical issue that should be considered. Carbon fiber–reinforced polymer (CFRP) and glass fiber–reinforced polymer (GFRP) in several forms and installation methods have been studied as the alternatives to the classical steel bar. Extensive laboratory tests on the materials and field tests on different types of soil nails with various methods of installation have been carried out in Hong Kong, Korea, and Australia. Test results support the use of these materials with an innovative installation method as soil nails under different geological conditions, and the suitability and performance of these materials under different conditions are assessed in the present study.

The study aims to assess the relationship between the body structure, physical fitness, and functional parameters of the respiratory system of the cadets from the General Tadeusz Kościuszko Military University of Land Forces (AWL) and their results in passing selected obstacle courses. The research material was collected from testing cadets of the third year of management studies. The research included anthropometric measurements, physical fitness tests, spirometry, and tests determining the level of passing selected obstacle courses. Body height and weight were measured. The body mass index was also calculated. Besides, the following functional characteristics were measured: cardiopulmonary endurance, functional strength, running speed and agility, balance, forced expiratory volume in 1 second, forced vital capacity, and peak expiratory flow. The study also included tests determining the level of passing the land and water obstacle courses. Statistically significant relationships were found between height and weight, balance, and forced expiratory volume in 1 second. Moreover, there were correlations between body weight and body mass index and the results in passing the land obstacle course. In addition, there were connections between cardiopulmonary endurance and performance in passing the land obstacle course, body balance, and performance in passing the land and water obstacle course. All the relationships mentioned above were low and statistically significant.

The Relationship

In view of the large movement required to mobilise the base resistance of bored piles and difficulty in base cleaning, the end bearing resistance often ignored in current design practice that will result in excessive rock socket length. Many attempts have been made to correlate the end bearing resistance with the uniaxial compressive strength of intact rock and the RQD but it is uncertain how applicable they are to rock type in Malaysia. This paper attempts to review the applicability of the formulas from previous studies to rock type in Malaysia. A program of field tests for 13 bored piles with diameter varying from 1000 mm to 1500 mm constructed in granite was conducted to measure the axial response of bored piles, tested using static load test and high strain load dynamic test to verify its integrity and performance. The results were evaluated and compared to the predicted rock bearing resistance. Based on the result obtained, the method by AASHTO gives the best prediction of rock bearing resistance for granite in Malaysia. However the relationship between compressive strength and rock discontinuities with the rock bearing resistance showed scattered results

Reactions To Feedback

This paper focuses on explaining how individuals set goals on multiple performance episodes, in the context of performance feedback comparing their performance on each episode with their respective goal. The proposed model was tested through a longitudinal study of 493 university students’ actual goals and performance on business school exams. Results of a structural equation model supported the proposed conceptual model in which self-efficacy and emotional reactions to feedback mediate the relationship between feedback and subsequent goals. In addition, as expected, participants’ standing on a dispositional measure of behavioral inhibition influenced the strength of their emotional reactions to negative feedback.

Abstract. Identifying pilot attributes associated with risk is important, especially in general aviation where pilot error is implicated in most accidents. This research examined the relationship of pilot age, expertise, and cognitive functioning to deviations from an ideal circuit trajectory. In all, 54 pilots, of varying age, flew a Cessna 172 simulator. Cognitive measures were obtained using the CogScreen-AE ( Kay, 1995 ). Older age and lower levels of expertise and cognitive functioning were associated with significantly greater flight path deviations. The relationship between age and performance was fully mediated by a cluster of cognitive factors: speed and working memory, visual attention, and cognitive flexibility. These findings add to the literature showing that age-related changes in cognition may impact pilot performance.
