  • Investigation of skills acquired by athletes during their sporting career

    • Authors: Nikolaos Matsankos; Dimitris Gargalianos, Silvia Coppola, Rodolfo Vastola, Andrea Petromilli
      Abstract: The present study was implemented in the context of the Erasmus+ program titled “AFTERMATCH - Life Beyond Sport”, the purpose of which was to investigate whether athletes acquire any skills from their involvement with sport that they can transfer in their profession after they finish their sporting career. The methodology employed was quantitative (questionnaires) and qualitative (interviews). The sample consisted of 23 active athletes, 64 former athletes and 39 employers / HR managers of companies in five different European Union countries (Bulgaria, Greece, Italy, Poland, Slovenia). A descriptive approach was used for the data analysis. The results showed that athletes acquire certain skills from their engagement in sport and those who realize it and use them make their transition to the labour market easier.

  • Professional competences and selective procedures of teachers: Application
           of an analytical vision to corporal and musical expression

    • Authors: Manuel Ricardo Vicente-Bújez; María Teresa Díaz-Mohedo, Alejandro Vicente-Bújez, Jesús López-Belmonte
      Abstract: The current constantly changing educational system requires reflexions about the role of teaching staff in the realm of corporal expression (in this case in primary education). These enable discovery and understanding of the professional competencies present in teaching practice, and how they are used in current selective processes. Thus, a qualitative study is presented that reports a case study using semi-structured interviews and focus groups as data collection tools, alongside a normative analysis of literature. In this sense, the study seeks to generate information about the importance of the professional competencies of teachers of Physical Education and Music Education in exercising corporal expression. This serves as a basis for a quality education that respects the characteristics present in the teaching environment and is sculpted to the specific needs of the pupils being taught. All of this aims to examine to what extent these competencies are present in current selective processes used by teachers within educational administrations, in this case, in the context of the autonomous community of Andalusia. In conclusion, selective systems will be deliberated in turn with the aim of proposing lines of research that offer more coherence and avoid the strong contradictions currently found within epistemological development in the training processes of teachers. The foundations for teacher selection that should be common when accessing the current system of public teaching will also be considered.

  • Virtual reality in sports coaching, skill acquisition and application to
           surfing: A review

    • Authors: Oliver R.L. Farley; Kirsten Spencer, Livvie Baudinet
      Abstract: The last decade, notably the past two years, have seen significant advancements in virtual reality (VR) technology, especially within the development of 3D and 360° virtual environments. Smart Phone technology now allows for head mounted display of this environment which is much more user friendly and cost effective. Sport training can now take full advantage of the improved quality of operating systems and as a result, VR provides visual simulations and immersive, interactive environments. VR technology is becoming more popular with evident influence on collecting various physiological aspects, identifying and improving sensorimotor capabilities, replicating competition and environment situations where reaction time is critical, and developing skill acquisition. This paper, therefore, reviews the existing literature relating to VR and the use of the technology used within sport, skill acquisition and coaching. Specifically, the paper describes VR, examines the uses of VR in sports, the applicability of methodological approaches used along with findings, limitations and the implications for coaching and athlete practice. Additionally, this review reports on VR used within skill acquisition learning/teaching and identifies how the technology can apply to surfing skill development. This paper will promote new ways to hone specific, hard to obtain skills, encouraging novel thinking for coaches.

  • Development of physical fitness under consideration of talent-specific

    • Authors: Andreas Roth; Steffen CE Schmidt, Sina Hartmann, Swantje Scharenberg, Ilka Seidel, Stefan Altmann, Darko Jekauc, Klaus Bös
      Abstract: Purpose: To measure the initial level and development of physical fitness (PF) in pupils from grade 4 to grade 7 in sport schools with respect to the discipline, training volume and training years. Methods: A total of 1590 (1074 female, 516 male) pupils from sport schools in North Rhine-Westphalia (Germany) were tested in grade 4 and re-tested in grade 7 using the German Motor Test. Additionally, the discipline, training volume and training years were captured in grade 7 via questionnaire. Results: The initial level of PF of boys and girls lies above the German average and was influenced by discipline and training volume. The track and field athletes showed the best results compared to other sport disciplines. In relation to the normal population, boys showed a slight decrease in PF from grade 4 to 7 (F = 8.3; p = .004; η2 = .009) whereas the PF of girls remained stable (F = 1.1; p = .290; η2 = .003). The development of PF is influenced by sport discipline, training volume and the interaction between training volume and time. In total, the effect sizes were low. Conclusions: There is still potential to improve training and physical education at sport schools to raise the level of PF. Training years did not influence the initial level of PF or the development of PF. In further studies, more information on the type of training would be useful.

  • The educational inclusion in physical education, design and validation of
           the EF-IDAN2019 Questionnaire

    • Authors: Adrián Jesús Ricoy-Cano; Antonio Hernández-Fernández, Claudia De Barros-Camargo
      Abstract: The processes of educational inclusion of students with disabilities in the ordinary system have had a direct impact on pedagogical practices. It is considered that future teachers specialized in physical education should have extensive knowledge in attention to diversity and physical neuroeducation. The general objective of this study is to analyse if it is possible to design and validate the EF-IDAN2019 questionnaire in university students. To respond to this objective, a research process based on the quantitative paradigm is carried out. For the validation of the instrument, we have the participation of a sample of n = 359 university students. The analysis of results confirms our dimensions, and, on the other hand, reduces the initial questionnaire to six dimensions, obtaining at the end a new questionnaire of 24 items with high reliability indexes (Cronbach's Alpha = .986). The factor analysis can be done because a significant result is obtained in the KMO test = .771. Bartlett's sphericity test confirms that the factorial model is adequate. The values of kurtosis and asymmetry, as well as the standard deviation, support the factorial analysis. Based on these results, it can be concluded that it is possible to design and validate the EF-IDAN2019 questionnaire in university students.

  • Application of the Transtheoretical Model (TTM) to exercise behaviour
           among Macedonian college students

    • Authors: Abdulla Elezim; Gresa Elezi, Seryozha Gontarev, Georgi Georgiev
      Abstract: Background: This study examined the applicability of trans-theoretical model (TTM) to understand exercise behaviour among students in University "St. Cyril and Methodius" in Skopje. Methods: A cross-sectional descriptive study was conducted. The dependent variables analysed were exercise self-efficacy expectation, decisional balance (pros and cons), social support for physical activity and exercise enjoyment. The independent variable was stage of exercise behaviour change. 1066 students representing various disciplines on campus completed a valid and reliable questionnaire during regularly scheduled classes. More than 67 percent of sample were sedentary (pre contemplation, contemplation, or preparation) whereas 17,6% were in the action stage (regularly active < 6 months) and 14,9% were in the maintenance stage (regularly active > 6 months). Results: All of the TTM constructs differed significantly across exercise stages. Students who are in the action and maintenance stage show greater self-efficacy, social support from parents and peers, and they receive greater benefit from physical activity, compared to students who are in the pre-thinking and thinking stage. In addition, students who are in the action and maintenance stage, enjoy physical activity more than students who are in the pre-thinking stage. Students who are in the stage of preparedness show greater self-efficacy than students who are in the pre-thinking and thinking stage and they receive greater social support from parents and peers, compared to students who are in the pre-thinking stage. Conclusion: Results supported the use of the entire TTM in examining exercise behaviour among college students.

  • Achievement goals in youth sport and the influence of coaches, peers, and
           parents: A longitudinal study

    • Authors: Joakim Ingrell; Urban Johnson, Andreas Ivarsson
      Abstract: The first purpose of this study was to longitudinally examine achievement goals in youth sport. The second purpose was to examine the within-person effects of perceived motivational climates by coaches, peers, and parents on achievement goal orientation. Participants were 78 young student-athletes, representing a variety of sports. The student-athletes completed a multi-section questionnaire, six times over a three-year period, assessing the study variables. Multilevel modelling analysis revealed that both task orientation and ego orientation decreased for this age group over the three-year period. Furthermore, perceived task-involving peer climate was significantly and positively related to task orientation, and perceived ego-involving coach climate was significantly and positively related to ego orientation. The results from this study provides insights regarding developmental changes in achievement goals and the importance of certain social agents in that specific developmental stage.

  • Study on the relationship between physical activity and the development of
           professional competence: Findings from a study in Ukraine

    • Authors: Javier Cachón-Zagalaz; María Sánchez-Zafra, Amador Lara-Sánchez, María Luisa Zagalaz-Sánchez, Daniil Shmatkov
      Abstract: The search for motivation for physical activity is always relevant, competitive advantages in the labour market are one of type of such motivation. This article presents the application of the developed method for identifying professionally important qualities as components of a student’s competency levels and their physical activity levels. 314 Ukrainian students, 442 of their parents and 104 professionals who have subordinates in the fields of education and technology were reviewed. We have detailed well-known studies in the field of professionally important qualities. In spite of this, it has been identified that professionals in general are mildly interested in the qualities obtained through a student’s physical activity. Wherein the lower r value between the weight of qualities mentioned by the athletes and their parents in comparison with the r value between the weight of qualities mentioned by non-athletes and their parents reveals an increased social mobility rate of athletes.

  • Programming of physical education and health-improving classes for the
           girls aged 12-13 years

    • Authors: Yaroslav Galan; Olena Andrieieva, Olena Yarmak, Olha Shestobuz
      Abstract: The research study presents the results of the pedagogical experiment that lasted during 2017-2018 academic year. Altogether 101 girls aged 12-13 years who, for reasons of health, are classified as primary and preparatory medical groups, were involved in the research. The purpose of the research was to determine the appropriate standards of physical fitness of 12-13-year old girls, which provide a stable level of physical health. To achieve this goal, an integrated approach was used using the following research methods: analysis and synthesis of special research and methodological literature and documentary materials; anthropometric methods; determination of the level of physical health; pedagogical testing; physiological methods; methods of mathematical statistics. The article presents the results of correlation relationships of indicators of motor tests and physical health. On their basis, regression equations were estimated to determine the appropriate values of physical fitness of girls aged 12-13 years with an average and below the average level of physical health. Through the use of factor analysis, we identified five statistically independent factors: muscular strength, speed-strength, agility, endurance and speed. The total contribution of these factors to the generalized variance of the sample is 89.6 %. We selected the most informative motor tests: for assessing muscle strength - shoulder flexor dynamometry (r = 0.759 with p < .01), speed-strength qualities – standing long jump (r = 0.800 with p < .01) speed - the difference between the time of shuttle run 3 × 10 m and 30 m (r = 0.808 with p < .01); endurance - relative performance (PWC150) (r = 0.869 with p < .01) and speed - 5 seconds running in the place at the maximum pace (r = 0, 0.860 p < .01). The results have prognostic value for the development of methods of training with a rational correlation of physical activity of various directions for a given age group.

  • Temporal trends in physical fitness and obesity among Brazilian children
           and adolescents between 2008 and 2014

    • Authors: Anelise Reis Gaya; Julio Brugnara Mello, Arieli Fernandes Dias, Caroline Brand, Vinícius Denardin Cardoso, Gabriel Alberto Kunst Nagorny, Jorge Mota, Antonio García-Hermoso, Adroaldo Cezar Araujo Gaya
      Abstract: The research aims to assess the trend of the health-related physical fitness over a period comprising 2008-2014, in two cohorts of a voluntary Brazilian school aged children and adolescents. Data was obtained from the database of Project Sport Brazil. The sample comprised children and adolescents aged between 10-17 years, assessed in two cohorts: 2008-2009 (6,281) and 2013-2014 (4,052) from different Brazilian regions. Measurement of the health-related physical fitness included: sit-up abdominal test, sit and reach, nine-minute of running/walking test, and body mass index. Descriptive data analyses and Poisson Logistic Regression were used. Prevalence trends of unhealthy flexibility increased significantly for boys from 35.2% to 38.4% and girls 23.5% to 38.0%, while prevalence on unhealthy abdominal strength/resistance decreased significantly for boys from 35.9% to 30.0% and did not show differences over time for girls. Overweight/obesity increased significantly over time in boys from 18.9% to 23.7%, as well as in girls from 19.4% to 28.0%. Cardiorespiratory fitness (CRF) showed the highest variation over time with a significantly increase of the unhealthy zone for both, boys from 33.4% to 61.3% and girls 33.3% to 66.6%. Therefore, we emphasize the importance of implementation national campaigns and interventions promoting physical activity in order to improve health.

  • Health and fitness benefits using a heart rate intensity-based group
           fitness exercise regimen

    • Authors: John Quindry; Cassie Williamson-Reisdorph, Joel French
      Abstract: Inactivity leads to morbidity and mortality, while novel and engaging approaches to fitness improve health outcomes. The current study examined an 8-week commercial group exercise regimen for high intensity interval training (HIIT) in order to examine comprehensive metrics of health and fitness. Aerobic fitness, body composition, resting metabolic rate, blood cholesterol and glucose, in addition to resting blood pressure were quantified in a laboratory setting independent of the training facilities. Exercise training utilized multimodal HIIT-based exercises and work intensity was gauged by real-time heart rate feedback. All participants completed the required two sessions per week. Pre-Post analyses indicate aerobic fitness (Pre O2max = 36.8 ml•kg-1•min-1; Post O2max = 40.8 ml•kg-1•min-1), % fat (Pre = 28.1%; Post = 27.0%), resting metabolic rate (Pre = 1557 kcals; Post = 1664 kcals), resting blood pressure (Pre = 128.8/78.1 mmHg; Post = 116.7/75.4 mmHg), and circulating triacylglycerol (Pre = 100.0 mg/dl; Post = 78.7 mg/dl) were significantly altered. This study quantified improvements in aerobic fitness, body composition, resting metabolic rate, resting blood pressure, and triacylglycerol after an 8-week HIIT regimen. The implications of heart rate (HR) monitoring within franchised group exercise with wearable technology serves as an unexplored scientific approach to understand novel exercise prescriptions on health-fitness outcomes. Future research should investigate sociological aspects of program adherence, while biological applications should examine the adaptive stimuli of HIIT training on health and fitness improvements.

  • Effect of home-based oculomotor exercises on postural stability in healthy
           female adults

    • Authors: Francesco Fischetti; Stefania Cataldi, Antonio Giunto, Gianpiero Greco
      Abstract: Visual information improves postural stability and facilitates stabilization of upright posture. To date, how saccades and smooth pursuit eye movements affect postural control is still a matter of debate. Therefore, the purpose of this study was to investigate the effects of oculo-motor exercises on static postural stability in healthy female adults. Participants (51.6 ± 4.9 years) were randomly allocated to an experimental group (n = 9) that performed 4-week home-based oculomotor exercises (i.e., saccadic eye movement and smooth pursuit) or a control group (n = 9). Pre and post postural stability during quiet standing with eyes open were measured on both groups. Significant ‘Time x Group’ interaction (p < .05) was found for Length Function of Surface, anterior-posterior acceleration, length of the oscillations, rearfoot load and body sway surface. By post hoc analyses, significant differences were found in all stabilometric parameters during quiet standing in the experimental group (p < .05). No significant differences were found in postural stability in the control group. Improvements in postural stability after four weeks of two combined oculomotor exercises suggest that this specific type of ocular system exercises may be beneficial for healthy female adults. In addition, the present investigation supports evidence that eye movements interact with the postural control system.

  • Optimal depth jump height quantified as percentage of athlete stature

    • Authors: Curtis L. Tomasevicz; Ryan Hasenkamp, Jack W. Ransone, David Jones
      Abstract: Purpose: An individual’s optimal depth jump platform height provides a resistive force which allows an athlete to rebound with substantial velocity resulting in maximum power exertion. The objective of this investigation was to show that the optimal platform height in a depth jump can be quantified as a percentage of individual body stature which can serve as measurable quantified value. Although athlete height is not highly correlated to power ability nor does a universal height exist, this value can provide a basis for a rehabilitation or strength and conditioning program. The desired intensity of a program can be prescribed as a percentage of the individual’s optimal drop height. Methods: Sixteen male participants (age = 21.7 ± 1.54 yrs., height = 177.7 ± 11.4 cm, mass = 77.7 ± 13.6 kg; mean ± SD) were tested in a depth jump through a range of platform heights based on percentage of the individual anthropometric data defined at 0-, 10-, 20-, 30-, 40-, and 50% of the participants’ stature using a 3-D motion capture system (Qualysis) and force plates (Bertec) to calculate power. Results: The optimal drop height was found to be 21.3 (±10.3)% of the participants’ heights for maximum peak power and 27.5 (±15.3)% for maximum average power. Conclusions: These results suggest that an individual optimal drop height does exist as a percentage of stature and could be applied to a rehabilitation or power-based training program using the drop height as a quantified basis allowing an athlete to gradually work toward their individual optimal drop height and exhibit maximum power.

  • Trampoline performance under changing visual conditions

    • Authors: Thomas Heinen; Frederike Veit
      Abstract: Picking up and utilizing visual information is thought to be of high importance in the control of trampoline skills. Yet, the question arises how information from the different vision systems contributes to trampoline gymnastics performance. The aim of this study was to examine the role of binocular and monocular visual information in trampoline gymnastics. N = 12 gymnasts performed straight leaps on the trampoline under full vision, monocular vision, and under occluded vision. Gymnasts’ preferred flight duration as well as gymnasts’ variable error in feet placement on the trampoline bed were analysed by means of an optic movement analysis system. Results revealed that gymnasts exhibited longer flight duration in the binocular vision condition and the monocular vision condition, as compared to the occluded vision condition. Gymnasts furthermore exhibited a larger variable error in feet placement with less visual information available. It is argued that gymnasts benefit from the availability of binocular information in order to perform precise leaps on the trampoline. Nevertheless, it is argued that utilizing visual cues in trampoline gymnastics is likely to depend on the current configuration of task-constraints (i.e., performing straight leaps vs. somersaults with and without twists).

  • Injury incidence, characteristics and timing in amateur male rugby union:
           A prospective cohort study

    • Authors: Alex Falkenmire; Joshua Manvell, Robin Callister, Suzanne Snodgrass
      Abstract: Rugby union has a high incidence of match injuries. However, there is limited information regarding the incidence and characteristics of match injuries in male amateur players. In particular, there is a lack of information regarding injury rates per match quarter. Investigating this may inform injury prevention strategies. The aim is to determine whether the rate and characteristics of injury vary with match quarter in male amateur rugby union players, regardless of whether the injury resulted in time loss from play. This prospective cohort study recorded and examined the number and characteristics of injuries during match quarters across a season of amateur rugby union. Team match exposure was recorded. Injuries were recorded by a team physiotherapist consistent with Rugby Injury Consensus Group guidelines. Matches were divided into quarters for data analysis, and statistical significance was determined using Chi-square analysis. 127 players sustained 207 injuries across 18 games. The injury incidence was 164 injuries/1000 match hours. There was a significant (p < .001) difference in the number of injuries between match quarters, with the greatest number in the fourth, followed by the second, third, and first quarter. Forwards had a statistically significant higher rate of injury between quarters. Injury incidence in amateur rugby is higher than previously reported. Injury rates in amateur male rugby increase at the end of each match half, peaking in the fourth quarter. These findings contribute to the understanding of the aetiology of injury in amateur rugby union.

  • Comparison of two methods in the estimation of vertical jump height

    • Authors: Madison Grainger; Alanna Weisberg, Pro Stergiou, Larry Katz
      Abstract: Vertical jumps are vital aspects in many sports. Many technologies are available to determine and calculate jump height. One such portable and easy-to-use technology is an Inertial Measurement Unit (IMU) that uses accelerometers, gyroscopes, and magnetometers. The purpose of this study was to compare vertical jump heights calculated from the data captured with an IMU versus true jump height calculated using a gold standard 3-Dimensional Motion Capture system. Ten subjects completed five jumps for six different conditions including vertical counter-movement jumps and jumps involving rotations on the ground and using a trampoline. An average Pearson correlation coefficient of .87 was found between the IMU and motion capture for all conditions. Condition correlations ranged from .76 to .94. Bland-Altman analyses showed that the IMU underestimated the vertical jump height compared to the motion capture by 5.0 to 9.2 cm across all conditions. Results suggest an IMU can be used to measure jump height in a laboratory setting with a reasonable accuracy, even during vertical jumps that include rotations.

  • Men's doubles professional tennis on hard courts: Game structure and
           point ending characteristics

    • Authors: Rafael Martínez-Gallego; Miguel Crespo, Jesús Ramón-Llin, Santiago Micó, José Francisco Guzmán
      Abstract: Despite the great tradition and importance of the doubles game in professional tennis, no literature has analysed to date the performance of professional players. Therefore, the information on the characteristics of the game, or the tactics related to how the points are won in doubles play is scarce. The objective of this study has been to describe the basic characteristics of the structure of the doubles game, and to establish how the points finish in doubles professional tennis played on hard courts. Thirty-four ATP doubles matches played in 2018 were analysed, which included a total of 40 professional players. As per the game structure, the results showed that, in comparison to the singles matches, the number of points per match, the number of sets per match, the number of points per game, and the number of strokes per point, are lower in the doubles matches. However, the number of games per set is higher in doubles than in singles. Winning shots and winning serves are the most frequent patterns to finish the point in doubles. These data show the great importance of the serve in doubles, as well as the relevance of using offensive tactics.

  • Maximum ball in play demands for sub-elite Rugby Union referees in
           domestic club rugby

    • Authors: Brett Allan Igoe; Declan Browne
      Abstract: Purpose: Rugby union referee research has reported the game demands for whole game averages and comparisons between each half and 10 minute periods. No study has reported the movement game demands for the maximum ball in play time for referees. The purpose of this study was to quantify the maximum ball in play (Max BiP) demands termed “worst case scenario” (WCS) of sub-elite rugby union referees using 10Hz Global Positioning System (GPS) units. Method: Movement demands of ten (n = 10) sub-elite referees across 27 matches, played during the 2017/18 All Ireland League Division 1, was calculated using 10Hz GPS units. The total distance covered (m), relative distance (m.min-1), percentage time in 6 velocity zones, were reported across the whole match, 1st half, 2nd half, 10minute periods and the maximum ball in play time using paired sample t-tests. Cohen’s d effect sizes were reported. Results: The maximum ball in play time was reported to be 172 ± 71 sec. The relative distance during Max BiP (107.9 ± 22.54 m.min-1) was significantly higher (p < .005) than whole match (75.1 ± 8.6 m.min-1) and 1st half (75.4 ± 8.7 m.min-1) & 2nd half (74.8 ± 13.1 m.min-1). During the Max BiP, referees spend a significantly higher (p < .005) percentage of time above whole game averages for walking (.5 - 2.0 m.s-1), jogging (2.01 - 4.0 m.s-1), running (4.01 - 5.5 m.s-1) and lower for high speed running (5.51 - 7.00 m.s-1) and sprinting (> 7.01 m.s-1). Conclusion: The results of this study quantifies the Max BiP movement demands for a sub-elite rugby union referee which are higher than those reported in whole game averages, 1st & 2nd halves and some 10min periods. These results provide sports scientists with the worst case scenario demands and can allow for these demands to be replicated in training with those experienced in matches.

  • The relationship between isokinetic knee flexion and extension muscle
           strength, jump performance, dynamic balance and injury risk in female
           volleyball players

    • Authors: Çağlar Soylu; Emre Altundağ, Cengiz Akarçeşme, Necmiye Ün Yıldırım
      Abstract: The relationship between balance, knee muscle strength, jump height and risk of injury has not been clearly stated in female volleyball athletes. The study was to determine whether a correlation exists between knee joint isokinetic muscle strength, risk of injury, balance and jump height in female volleyball athletes. Twenty-two female volleyball athletes were involved into the study. Knee muscle strength were evaluated with the Biodex 3® isokinetic dynamometer. Jump performances were evaluated with the countermovement (CMJ) jump test using the Vert Jump® Motion Sensitive Sensor. The injury risk for all players were evaluated by the Functional Movement Screen (FMS®). Balance measurements were performed with a dynamometer Biodex Systems 3® device. There was a significant relationship between CMJ height, knee flexion and extension peak torque and H:Q ratio values at two angular velocities, dynamic balance and total FMS® scores (p < .05). However, contralateral deficit statistically significant were not related between CMJ height, dynamic balance and FMS® scores (p > .05). We suggest that all clinicians and coaches involved in the protective and preventive rehabilitation phase evaluate these parameters and plan their training programs in line with the results obtained in increasing both individual and team performance of athletes.
