Expected and perceived service quality at basketball stadiums in Greece

Abstract The purpose of the current research was to examine the differences between expected quality of service and the perceived quality of service experienced by spectators at selected professional basketball stadiums in Northern Greece. Five hundred spectators filled in the evaluation instrument created for the purpose of the study. The Wilcoxon's matched-pairs signed-ranks test showed a statistically significant difference in all 23 items between expectations and perceptions of service quality and in all cases only organizational weaknesses were proved to exist and no strengths. The exploratory factor analysis revealed nine factors: "show time expectotions", "instollation's evaluation", "convenience ond employee evoluation", "show time evoluation", "employee expectations", "convenience expectotions", "instollotion's expectotions", "comfort evaluation" and "comfort expectations". The challenge of providing o high quality sport and recreation service becomes less difficult when sport managers know what their customers expect from a service and what they feel i s important to quality. From a managerial perspective, identifying the dimensions and knowing both a spectator's evaluations and expectations of a provided service indicates the direction that management should take in investing its efforts and resources to increase the probability of the customer experiencing a positive outcome from watching

Enhancing motor competence and physical activity in kindergarten

Background: This study aimed at evaluating the effect of the “Walk,” an 8-month physical activity (PA) program led by classroom and physical education teachers, on the motor competence (MC) and PA of 5- to 6-year-old children. Methods: A total of 143 children (mean age = 61.51 [1.85] mo) participated in the study and were randomly assigned to the experimental and control groups. Children's MC was assessed by the Körperkoordination Test für Kinder (KTK), and PA was objectively measured by Omron HJ-720IT-E2 pedometers. Measurements were performed at baseline, midintervention, and postintervention. A 1-sample t test computed at baseline step counts revealed that children presented significantly lower PA than recommended for their age (P < .001). To examine the effect of the intervention on children's MC and PA, several repeated-measures analyses of variance were utilized on (1) KTK item scores and (2) pedometer data. Results: The results revealed that the Walk project led to practically significant changes in the experimental group compared with the control group in both MC (P < .001, η 2 > .14 for all KTK items) and PA (P < .001, η 2 = .23). Conclusions: This study highlights the efficacy of a PA project, involving both classroom and physical education teachers, for the enhancement of children's MC and PA. © 2019 Human Kinetics, Inc

The influence of the hand’s acceleration and the relative contribution of drag and lift forces in front crawl swimming

Abstract: The aim of this study was to assess the effect of the hand’s acceleration on the propulsive forces and the relative contribution of the drag and lift on their resultant force in the separate phases of the front crawl underwater arm stroke. Ten female swimmers swam one trial of all-out 25-m front crawl. The underwater motion of each swimmer’s right hand was recorded using four camcorders and four periscope systems. Anatomical landmarks were digitised, and the propulsive forces generated by the swimmer’s hand were estimated from the kinematic data in conjunction with hydrodynamic coefficients. When the hand’s acceleration was taken into account, the magnitude of the propulsive forces was greater, with the exception of the mean drag force during the final part of the underwater arm stroke. The mean drag force was greater than the mean lift force in the middle part, while the mean lift force was greater than the mean drag force in the final part of the underwater arm stroke. Thus, swimmers should accelerate their hands from the beginning of their backward motion, press the water with large pitch angles during the middle part and sweep with small pitch angles during the final part of their underwater arm stroke. © 2014, © 2014 Taylor & Francis

The effect of leg kick on sprint front crawl swimming

The aim of this study was to examine the influence of leg kick on the pattern, the orientation and the propulsive forces produced by the hand, the efficiency of the arm stroke, the trunk inclination, the inter-arm coordination and the intra-cyclic horizontal velocity variation of the hip in sprint front crawl swimming. Nine female swimmers swam two maximal trials of 25 m front crawl, with and without leg kick. Four camcorders were used to record the underwater movements. Using the legs, the mean swimming velocity increased significantly. On the contrary, the velocity and the orientation of the hand, the magnitude and the direction of the propulsive forces, as well as the Froude efficiency of the arm stroke were not modified. The hip intra-cyclic horizontal velocity variation was also not changed, while the index of coordination decreased significantly. A significant decrease (13%) was also observed in the inclination of the trunk. Thus, the positive effect of leg kick on the swimming speed, besides the obvious direct generation of propulsive forces from the legs, could probably be attributed to the reduction of the body's inclination, while the generation of the propulsive forces and the efficiency of the arm stroke seem not to be significantly affected. © 2013 Taylor & Francis
