The professionalisation of sports coaching: relations of power,resistance and compliance

This paper analyses the capacity of youth sport volunteering to contribute to the development of social capital. Following a review of the emergence of social capital as a key theme in UK sport policy, the paper focuses on the ability of a structured sports volunteering programme to equip young people with skills for effective volunteering, and provide opportunities for ‘social connectedness’ through sports volunteer placements. The study uses survey data (n=160) and qualitative interviews (n=10) with young people to examine how the national Step into Sport programme impacts on participants’ personal and skill development, and on their commitment to community involvement. Interviews with education and sport professionals (n=33) provide additional expert perspectives on the programme's impact on participants. Both sets of respondents report strong individual benefits to participants from their involvement, and increased social connectedness in a range of contexts. The paper concludes by considering the implications of the study for claims about the potential contribution of sport to social capital.     

Examining the impact of an online social media challenge on participant physical activity and body weight in the United States

This study examined use of an online social media physical activity (PA) challenge to encourage participants to complete at least 13 races in the year 2013. Following the challenge, researchers recruited participants through the Facebook group. Using the #13in2013 Twitter hashtag, participants completed an online survey. Survey participants reported completing a significantly greater mean total number of races during the challenge (17.5 ± 6.9 races) than the previous year (8.6 ± 7.4 races, p = .001) and 93% (n = 56) reported completing at least 13 races. Participants completed a mean of 1.4 ± 2.1 virtual races. Mean reported number of total miles ran/walked during the challenge was significantly greater (718.4 ± 465.0 miles) than the previous year (462.1 ± 436.5 miles, p = .002). Mean reported participant body weight post-challenge (68.2 ± 13.1 kg) was significantly lower than reported weight pre-challenge (69.7 ± 14.4 kg, p = .012). This study demonstrated that a social media PA challenge has the potential to present a scalable way to motivate individuals to participate in PA and decrease body weight.     

The effects of goal variation on adult physical activity behaviour

The purposes of this study were to examine the effects of varying levels of goals on increasing daily steps and the frequency of goal achievement among middle-aged adults. Ninety-six adults participated in a randomised control study. Participants were randomly assigned to five different step goal groups: (1) Easy (n = 19), (2) Medium (n = 19), (3) Difficult (n = 19), (4) Do-your-best (n = 19), and (5) No goal (n = 20) based on previous research. The participants wore a pedometer and were asked to reach a pre-established goal during the experimental period. In order to examine the effectiveness of the goal difficulty, (a) an average number of steps taken by different goal conditions and (b) the number of days meeting the assigned goal were tested. A one-way ANCOVA revealed significant step count differences among goal groups. Post hoc analyses indicated that the change in step count in both the Medium and Difficult goal groups was significantly greater than the remaining groups. However, there was no significant difference between the medium and difficult goal conditions. In addition, a one-way ANOVA indicated that there were no significant differences in the frequency of goal achievement among the Easy, Medium, and Difficult goal groups. Results suggest that when promoting physical activity through increasing step counts, researchers and clinicians should design goals that are specific and challenging.     

The value profile of physical education teachers in Taiwan,ROC

The purpose of this study was to ascertain the educational value orientations of physical education teachers in Taiwan, and the relationships of gender, teaching experience, grade level, and the locations in which they work. Value orientations were measured with the Value Orientation Inventory-2, which was translated into complicated Chinese for this study. Participants (N=353) were recruited via stratified random sampling from the population of physical education teachers in Taiwan; 152 participants had one high-priority value orientation and a smaller number (n=76) had more than one high-priority value orientation. Other physical education teachers (n=124) had one or more low-priority value orientations. Taiwanese physical educators possess multiple, diverse value orientations and the largest percentage of strong value orientation scores was for the value orientation of learning process. The specific characteristics of Taiwanese physical educators include: (a) more males prioritizing disciplinary mastery and learning process, but more females prioritizing social responsibility; (b) more experienced teachers prioritizing learning process; (c) more elementary school teachers prioritizing social responsibility; and (d) more rural teachers prioritizing disciplinary mastery and learning process. Both the culture and the curriculum goals of physical education contribute to the differences of value orientations. Thus, Taiwanese physical educators emphasize self-control, self-concept, and social responsibility to achieve the coordination of body and spirit in their practices.     

Youth Leaders' Perceptions of Commitment to a Responsibility-Based Physical Activity Program

This study extended Schilling's (2001) study by investigating program commitment among a larger (N = 12), older (M = 16.7 years), and more experienced (M = 5.96 years) sample of participants in the Project Effort Youth Leader Corps. Individual interviews elicited a greater number and specificity of themes. Program-related barriers included logistics, structure, and relationships, and personal-related barriers included perceived alternatives, personal characteristics, and “real-life” responsibilities. Similar to Schilling's (2001) earlier study, antecedents grouped under program environment, program structure, relationships, and personal characteristics. Participants also described outcomes in terms of behavior and emotional involvement but reported more themes related to leadership. Results are discussed in terms of consistencies and changes over time and implications for program development, expansion, and evaluation.     

Motivational factors for youth recruitment in voluntary interventions: the case of a community sport program

Recruitment is known to be a challenge for intervention programs targeting youths, including sports programs. Following the popularity of the Alter-Action program of the Montreal-based organization DesÉquilibres, we wanted to understand the motivations and barriers to youths' recruitment in this voluntary sports community program. A qualitative methodology was favored. We conducted 27 semi-structured interviews (n = 27) with participants, 5 (n = 5) with the partners, and we carried out a focus group with 5 (n = 5) of the organization's service practitioners. We also conducted a participant observation with youth cohorts and during preparatory meetings. Five factors influencing recruitment emerged: (1) socialization/belonging; (2) training/physical aspects; (3) ‘extraordinary’ dimension; (4) practicality of the program; and (5) social influences. Four key elements thus appear important to consider when promoting the recruitment of youths in voluntary community programs: (1) favoring social interactions; (2) insisting on the specific and beneficial elements of the program; (3) allowing youths to experiment a trial period; and (4) including testimonies of former participants in the information session. Further recommendations for psychosocial intervention programs targeting youths are discussed in this article.     

Examining the influence of acute instructional approaches on the decision-making performance of experienced team field sport players

Abstract

We examined the influence of instructions on decision-making accuracy using video simulations of game-specific scenarios in Australian football. Skilled performers (average age of 23.4 ± 4.2 years) differing in experience (range 0 to 339 Australian Football League (AFL) matches) assumed the role of the key attacker and verbally indicated their kicking decision. Participants were randomly stratified into three groups: (1) LOOSE (n = 15) – instructed to “keep the ball away from the loose defender”; (2) TTF (n = 15) – instructed to “take the first option”; and (3) NI (control) (n = 16) – given no instructions. Gaze behaviour for a subset of participants (n = 20) was recorded. In the scenarios with an even number of attacking and defensive players, the decision-making accuracy of LOOSE was greater than TTF. This difference was most evident for lesser experienced performers, highlighting that lesser experienced performers are more affected by instructional foci than experienced performers. Gaze behaviour was not affected by instructional foci, but visual search rate was greater in scenarios of greater player number and complexity.     

Energy,macronutrient and water intake during a mountain ultramarathon event: The influence of distance

Adequate dietary strategies are essential for the successful participation in ultra-endurance races. The aim of this study was to evaluate and compare the energy and water intakes of participants during three different mountain ultra-endurance runs. The study took place at the “Ultra Mallorca Serra de Tramuntana” (Mallorca, Spain), an ultra-endurance mountain event with runners participating either in a 44-km (Marathon, n = 51), a 67-km (Trail, n = 109) or a 112-km (Ultra, n = 53) run competition. Participants in the study answered a questionnaire focused on the nutritional intake within an hour after finishing the competition. Mean energy intake during the competitions was 183 kcal · h^¯1, with an average carbohydrate intake of 31 g · h^¯1 (52.1% of participants consumed less than 30 g · h^¯1). No significant differences between competitions were found in these parameters. However, a higher percentage of energy from lipids in participants in the Trail and the Ultra was found (P = 0.034). Furthermore, significant differences were observed in water intake per hour of competition (P = 0.039), with the lowest value for the intake during the Ultra competition. In conclusion, the majority of the participants in the study present low carbohydrate intakes. However, fluid intake seems to be adequate. Different distances did not significantly influence the participants’ nutritional strategies.     

A descriptive-comparative study of performance characteristics in futsal players of different levels

Despite the increasing popularity of futsal, there is little information on performance characteristics of players. We aimed to determine the validity and reliability of a futsal shooting test and to evaluate and compare performance characteristics of three futsal playing levels. Twenty-four males (n = 8 elite, n = 8 semi-elite, n = 8 social) completed two trials to examine the reliability of the Massey Futsal Shooting Test (MFST) and to compare various fitness characteristics between groups. MFST time taken (P = 0.010), shot speed (P < 0.001) and points scored per shot (P < 0.001) were better for elite relative to social players. Test–retest reliability was acceptable for all groups, but it was most repeatable in elite players. Loughborough Soccer Passing Test performance was better in elite relative to social players (P = 0.004). There were no differences in countermovement-jump height between groups. Elite players ran faster over 5 m than both semi-elite (P = 0.043) and social (P = 0.002) and faster than the social players through 10 m (P = 0.028) and 20 m (P = 0.026). Distance covered in the Futsal Intermittent Endurance Test was higher in elite relative to semi-elite (P = 0.005) and social (P < 0.001) groups. The MFST is a valid and reliable protocol to assess futsal shooting-skill performance; elite players have superior shooting and passing skill and have greater sprinting and intermittent-running ability.     

Straight sprinting is the most frequent action in goal situations in professional football

Abstract

The present study aimed to analyse the influence of speed and power abilities in goal situations in professional football.

During the second half of the season 2007/08, videos of 360 goals in the first German national league were analysed by visual inspection. For the assisting and the scoring player the situations immediately preceding the goal were evaluated. The observed actions were categorised as: no powerful action, rotation (around the body's centre-line), straight sprint, change-in-direction sprint, jump, or a combination of those categories.

Two hundred and ninety-eight (83%) goals were preceded by at least one powerful action of the scoring or the assisting player. Most actions for the scoring player were straight sprints (n = 161, 45% of all analysed goals, P < 0.001) followed by jumps (n = 57, 16%), rotations and change-in-direction sprints (n = 22, 6% each). Most sprints were conducted without an opponent (n = 109, P < 0.001) and without the ball (n = 121, P < 0.001). Similarly, for the assisting player the most frequent action was a straight sprint (n = 137, P < 0.001) followed by rotations (n = 28), jumps (n = 22) and change-in-direction sprints (n = 18). The straight sprints were mostly conducted with the ball (n = 93, P = 0.003).

In conclusion, straight sprinting is the most frequent action in goal situations. Power and speed abilities are important within decisive situations in professional football and, thus, should be included in fitness testing and training.     

Comparing effects of a TPSR training program on prospective physical education teachers’ social goals,discipline and autonomy strategies in Spain,Chile and Costa Rica

Background: Conflict prevention, respect, tolerance and acceptance of others should be basic outcomes in any educational context. Physical Education (PE) has the potential to be one of the curricular subjects that could help students meet these goals. However, teachers need to use appropriate instructional approaches like Teaching for Personal and Social Responsibility (TPSR).

Purpose: The objectives of this study were two: (1) to compare the impact of TPSR training on social goals, discipline strategies and autonomy support of future PE teachers from Spain, Chile and Costa Rica; and (2) to assess participants’ perceptions of their country's social, cultural and curricular aspects that may influence TPSR implementation.

Participants and settings: 156 prospective PE teachers (48 from Spain, 54 from Chile and 54 from Costa Rica), with an average age of 21.41?±?2.57 years, agreed to participate. 88 (54%) were males, while 75 (46%) were female. They were enrolled in teacher training programs in three different universities located in three different countries: (i) Faculty of Education of the University of Burgos (Spain); (ii) Nursery School of the University of Valparaiso (Chile) and (iii) School of Physical Education and Sports of San José (Costa Rica). All students experienced the same TPSR intervention program, conducted by the same university teacher.

Research design: This study followed a quasi-experimental, pre-test/post-test non-equivalent research design with mixed methods.

Data collection: Three validated questionnaires were used to obtain quantitative information from the participants before and after the training program. Qualitative information was obtained from three discussion groups conducted with the participating students (one from each country).

Data analysis: Statistical analysis of quantitative data was conducted with the statistical package SPSS (version 22.0), while content analysis and constant comparison were used to assess qualitative data.

Findings: The prospective PE teachers from the three countries held different views of the effects of the TPSR program on social goals, discipline strategies and autonomy support, and they were based on socio-cultural considerations of the subject (PE), the teachers’ academic training and their professional identity as teachers on each country. Spanish and Costa Rican PE teachers demonstrated a significant positive change in their perspectives on discipline strategies, and Chilean PE teachers demonstrated a significant positive change in their perception of social goals after experiencing a TPSR intervention.

Conclusion: If cultural context is considered, TPSR can be an effective teacher training approach related to discipline strategies, social goals and autonomy support in PE.     

Impact sports and bone fractures among adolescents

The objective of the present study was to investigate the effects of different sports on stress fractures among adolescents during a 9-month follow-up period. The sample was composed of 184 adolescents divided into three groups (impact sports [n = 102]; swimming [n = 35]; non-sports [n = 47]). The occurrence of stress fracture was reported by participants and coaches. As potential confounders we considered age, sex, resistance training, body composition variables and age at peak of height velocity. There were 13 adolescents who reported fractures during the 9-month period. Bone mineral density values were higher in adolescents engaged in impact sports (P-value = 0.002). Independently of confounders, the risk of stress fracture was lower in adolescents engaged in impact sports than in non-active adolescents (hazard ratio [HR] = 0.23 [95% confidence interval (CI) = 0.05 to 0.98]), while swimming practice was not associated to lower risk of fracture (HR = 0.49 [95% CI = 0.09 to 2.55]). In conclusion, the findings from this study indicate the importance of sports participation among adolescents in the reduction of stress fracture risk, especially with impact sports. More importantly, these results could be relevant for recognising adolescents in danger of not reaching their potential for peak bone mass and later an increased risk of fractures.     

Prevalence of shoulder pain in Swedish flatwater kayakers and its relation to range of motion and scapula stability of the shoulder joint

Few studies have investigated the incidence of injuries in kayakers. The aim was to study the prevalence of shoulder pain in competitive flatwater kayakers and to evaluate any differences in range of motion or scapula stability of the shoulder joint among kayakers with or without the history of shoulder pain. Thirty-one kayakers were participated in the study, and a questionnaire including background data was used. Shoulder range of motion was measured with a goniometer, and the participants were observed for scapula dyskinesis in flexion and abduction. Of the participating kayakers, 54.8% (n = 17) had experienced shoulder pain. Kayakers who had experienced shoulder pain showed a significantly lower degree of internal rotational range of motion versus kayakers with no reported shoulder pain, with a mean degree of internal rotation in the right shoulder 49.3 vs 60.0 (P = 0.017) and the left shoulder 51.9 vs 66.0 (P = 0.000). Kayakers who had experienced shoulder pain were also observed with a scapular dyskinesis (n = 15 of 17 kayakers) to a significantly higher degree (P = 0.001) than kayakers with no reported shoulder pain. Findings suggest that screening for scapular dyskinesis and testing for rotational range of motion in the shoulder joint is essential in order to treat and maybe prevent shoulder pain in kayakers.     

Motivational priming as a strategy for maximising exercise outcomes: effects on exercise goals and engagement

Abstract

Using a scrambled sentence priming protocol, the first aim of this study was to investigate whether differences in novel exercise-related goals existed between participants primed with motivational or non-motivational material (i.e. autonomous, controlled or neutral primes). The second aim was to explore whether an indirect effect was present between priming condition and the goal-related exercise sessions that individuals performed over the week following administration of the prime. No effects were observed across priming conditions with respect to subjective vitality, goal concordance and the frequency with which participants planned to exercise. However, autonomy-primed individuals set goals for their exercise sessions that were significantly longer in intended duration (M = 57.72 min, SD = 37.42) than those set by their counterparts in both the controlled-prime condition (M = 44.12 min, SD = 27.78) and the neutral-prime condition (M = 37.10 min, SD = 20.47). Bootstrapped analyses also revealed a significant indirect relationship between prime and exercise behaviour, with the autonomy prime predicting longer goal-based exercise sessions, via the effect on the duration of participants’ intended exercise sessions. These findings highlight the potential influence that priming autonomous motivation may have on individuals’ exercise aspirations, as well as the way in which primes may indirectly shape exercise engagement.     

Effects of short-term exercise training on tissue Doppler indices of left ventricular diastolic function in overweight and obese individuals

Abstract

Although exercise training is unable to improve obesity-associated decreases in left ventricular (LV) diastolic function, as assessed using chamber function measurements, the effects on LV diastolic myocardial function, as assessed using tissue Doppler imaging (TDI), are uncertain. In 32 overweight (n = 11) or obese (n = 21), sedentary or recreationally active men and women (30–57 years), we assessed the effects of 6 weeks of exercise training either preceded (n = 16) or followed (n = 16) by a 6-week control period on TDI indices of LV diastolic function (e', e'/a' and E/e') (echocardiography). Diastolic function at baseline was comparable to that noted in overweight and obese participants from a community sample (n = 245), and 56% (n = 18) had e' values below the lower 95% CI of a lean and healthy cohort (n = 60) of the community sample. Exercise training increased peak oxygen consumption (27.4 ± 4.9 to 29.4 ± 5.8 mL · kg^–1 · min^–1, P = 0.0001), but had no effect on body mass index (P = 0.99). No changes in TDI indices of diastolic function were observed after exercise training in all the participants (e': P = 0.74, a': P = 0.98, e'/a': P = 0.85, E/e': P = 0.26), participants with abnormal e' values (n = 18)(e': P = 0.99, a': P = 0.96, e'/a': P = 0.91, E/e': P = 0.97) or obese participants (n = 21)(e': P = 0.67, a': P = 1.00, e'/a': P = 0.78, E/e': P = 0.11). In conclusion, exercise training, despite increasing cardiorespiratory fitness, is unable to improve obesity-associated decreases in LV diastolic myocardial function.     

Influence of sport type and interdependence on the developmental experiences of youth male athletes

Abstract

The purpose of this study was to examine the relationships between sport type, interdependence (task and outcome), and the developmental experiences of select male basketball players (n=129) and middle-distance runners (n=83) aged 14–17 years. Athletes completed the Youth Experiences Survey 2.0 (Hansen & Larson, 2005) and a modified measure assessing task and outcome interdependence (Van der Vegt, Emans, & Van de Vliert, 1998 Vliert, 2001). Hierarchical multiple regression determined that basketball players reported higher rates of teamwork and social skills, adult networks and social capital, and negative experiences. Furthermore, outcome interdependence was a predictor of identity exploration, initiative, emotional regulation, positive relationships, teamwork and social skills, and adult networks and social capital experiences independent of sport type. Although different sports may provide different learning environments, the developmental experiences youth garner may be more strongly influenced by how the people involved interact (outcome interdependence) than by the type of sport.     

Endurance and sprint benefits of high-intensity and supramaximal interval training

Abstract

This study examined the effect of two different interval training programs–high-intensity interval training (HIT) and supramaximal interval training (SMIT)–on measures of sprint and endurance performance. Physically active individuals (Females: n=32; age 19.3, s=2.2 years; mass 67.6, s=9.1 kg; stature 172.7, s=6.6 cm. Males: n=23; age 20.0, s=2.7 years; mass 71.3, s=8.3 kg; stature 176.6, s=5.8 cm) completed pre-testing that comprised (1) 3000 m time-trial, (2) 40 m sprint, and (3) repeated sprint ability (RSA–6×40 m sprints, 24 s active recovery) performance. Participants were then matched for average 3000 m running velocity (AV) and randomly assigned to one of three groups: (i) HIT, n=19, 4 min at 100% AV, 4 min passive recovery, 4–6 bouts per session; (ii) SMIT, n=20, 30 s at 130% AV, 150 s passive recovery, 7–12 bouts per session; and (iii) control group, n=16, 30 min continuous running at 75% AV. Groups trained three times per week for six weeks. When time to complete each test were compared among groups: (i) improvements in 3000 m time trial performance were greater following SMIT than continuous running, and (ii) improvements in 40 m sprint and RSA performance were greater following SMIT than HIT and continuous running. In addition, a gender effect was observed for the 3000 m time trial only, where females changed more following the training intervention than males. In summary, for concurrent improvements in endurance, sprint and repeated sprint performance, SMIT provides the greatest benefits for physically active individuals.     

The sensitivity of the alternative maximal accumulated oxygen deficit method to discriminate training status

The purpose of the study was to investigate the sensitivity of an alternative maximal accumulated oxygen deficit (MAOD_ALT) method to discriminate the “anaerobic” capacity while comparing: least trained (LT) participants (n = 12), moderately trained (MT) participants (n = 12), endurance trained (ET) participants (n = 16), and rugby (RG) players (n = 11). Participants underwent a graded exercise test on a treadmill and a supramaximal effort for assessing MAOD_ALT. MAOD_ALT was calculated as the sum of oxygen equivalents from the phosphagen and glycolytic metabolic pathways. MAOD_ALT was significantly higher (P < 0.05) in RG (64.4 ± 12.1 mL · kg^?1) than in ET (56.8 ± 5.4 mL · kg^?1; effect size [ES] = 0.77; +13.5%), MT (53.8 ± 5.3 mL · kg^?1; ES = 1.08; +19.8%), and LT (49.9 ± 4.5 mL · kg^?1; ES = 1.50; +36.4%). In addition, the magnitude-based inference analysis revealed that MAOD_ALT was likely (LT vs. MT), very likely (MT vs. RG, and ET vs. RG) and most likely (LT vs. ET, and LT vs. RG) different between all groups, except for MT and ET, which presented an unclear difference. In conclusion, MAOD_ALT was sensitive enough to distinguish the “anaerobic” capacity in individuals with different training status, especially for RG players compared with LT participants and MT participants.     

Managing sport for social change: The effects of intentional design and structure in a sport-based service learning initiative

The current study focused on addressing a gap in understanding the design, structure, and management of sport-for-development (SFD) initiatives, in this case an initiative rooted in sport-based service learning. Sport, and specifically SFD, has been shown to facilitate positive outcomes such as social capital development through expanding networks and community building. Some studies have focused on impacts on volunteers in sport and SFD programs. These volunteers have developed networks most often through informal relationship building activities. Building on this knowledge, the current mixed methods study investigated the social capital development of alumni of a college service learning through sport course. Survey data (n = 93) and individual interviews (n = 22) with participants who had completed at least one semester in the course indicated that social capital development was facilitated. In particular, the intentional design, structure, and management aspects of the course and program provided opportunities for social capital development.     

Gross motor coordination in junior tennis players

The purpose of this study was twofold: (1) to determine the gross motor coordination performance levels of junior tennis players and (2) to analyse the effects of age and gender. Participants were junior male (n = 50) and female (n = 51) tennis players aged 6–14. Körperkoordinationstest für Kinder (KTK) was used to assess the gross motor coordination of the participants. Results revealed that none of the participants performed lower than normal level in motor coordination. Besides, 40.6% of the participants performed above normal level. No gender differences were found on all subtests of KTK and also on total motor quotient. Although older players performed better on each test than their younger counterparts for the raw scores, no significant age effect was observed on motor quotient scores among different age groups.
