The aim of IJPEFS is to stimulate knowledge to professionals, researchers and academicians working in the fields of Physical Education, Fitness and Sports Sciences. https://ijpefs.org/index.php/ijpefs/article/view/371 Hand Grip Strength in Students: Differences in the Gender Dimorphism 2021-10-18T09:18:48+00:00 Ratko Pavlović pavlovicratko@yahoo.com Mensur Vrcić mensurvrc@gmail.com <p>The hands are anatomically specialized for manipulative tasks with different physical objects, where they can cope with certain loads with different forces and intensity. During various physical and sports activities, the hands produce the appropriate muscular force for gripping, which manifests as the hand grip's force. For this reason, hand grip strength (HGS) is recognized as a limiting factor in all manipulative activities performed by the cranial part of the body. The current research included a sample of 22 subjects, 16 male Body Height (BH=180.28±4.65cm); Body Weight (BW=80.05±9.96kg), Body Mass Index (BMI=24.61±2.74kg/m²) and 6 female subjects Body Height (BH=167.42±11.11cm); Body Weight (BW=64.80±10.09kg); Body Mass Index (BMI=23.02±1.57kg/m²) on the third year of study at the Faculty of Physical Education and Sports. This study aimed to determine the maximum isometric muscle force of the handgrip and differences between the same gender of students. A t-test for small samples was applied for data processing, and the relevant statistical parameters were calculated. The obtained t-test results confirmed statistically significant differences between the so-called dominant and non-dominant hands in male subjects (t=4.158; p&lt;0.05) and female subjects (t=3.176; p&lt;0.05). The obtained results of this research will be used for analytical and diagnostic purposes with a wide range of activities in the population of physical education and sports students (assessment of physical ability, trends, and tendencies to monitor and change abilities, influence on the implementation of certain curricula of some subjects studied at the faculty, etc.).</p> 2021-10-18T00:00:00+00:00 Copyright (c) 2021 Ratko Pavlović, Mensur Vrcić https://ijpefs.org/index.php/ijpefs/article/view/368 Comparing the strategies used to maintain the coach-athlete relationship in Japan and the United Kingdom 2021-10-09T04:05:06+00:00 Daniel Rhind yd97674@uga.edu Frank Owusu-Sekyere f.owusu-sekyere@kingston.ac.uk Daichi Ando daichiando@gmail.com <p>The present study explored the strategies used to maintain the quality of the coach-athlete relationship amongst rowers in Japan and the United Kingdom. A total of 93 athletes from Japan (N = 49) and UK (N = 44) completed the Coach Athlete Relationship Maintenance Questionnaire (CARM-Q) and the Athlete Satisfaction Questionnaire (ASQ). The results of T-tests showed that (a) university rowers in the UK were significantly more satisfied with the coach-athlete relationship than those in Japan; (b) the athletes in Japan expressed higher scores on Preventative strategies than the ones in the UK; (c) the athletes in the UK expressed higher scores on all other CARM-Q subscales with the exception of Social Networks. The results of correlation analyses revealed positive associations between the use of maintenance strategies and athlete satisfaction. These findings evidence the importance of coaches using strategies to maintain the effectiveness of their relationship with athletes as well as the importance of researchers taking cultural factors into account.</p> 2021-10-09T00:00:00+00:00 Copyright (c) 2021 Daniel Rhind, Frank Owusu-Sekyere, Daichi Ando https://ijpefs.org/index.php/ijpefs/article/view/359 Technology consideration in tennis umpiring: replacing the humans 2021-09-06T14:13:15+00:00 Jan Carboch carby@post.cz <p>New technologies step into sports refereeing, officiating, or umpiring. This technology can assist humans to avoid blunders or errors. However, in tennis, this technology now starts to replace humans, i.e. the line umpires. In this letter, we try to provide insight into potential problems, that this technology brings, but also we try to provide its benefits. We offer considerations from the umpire (human) view. It is not very clear and we consider it still in a grey zone, what are the next best steps, even though it seems that the new technology implementation is unavoidable. In this letter, we focus on tennis line umpires, because technology is replacing them now. Therefore, would like to encourage and call for more research on this currently hot topic.</p> 2021-10-04T00:00:00+00:00 Copyright (c) 2021 Jan Carboch
