Purpose: This study examined changes in physical education teachers’ psychosocial perspectives after participating in a yearlong professional development about Comprehensive School Physical Activity Programming. Method: Twenty-three intervention teachers attended a workshop in Year 1 and received one academic year of technical assistance and mentorship, and 30 control teachers only attended a workshop in Year 2. Both groups completed pre- and post-self-reported measures on teacher efficacy, work engagement, and affective commitment. Results: At posttest, intervention teachers reported significantly higher levels of affective commitment, and a significant positive relationship was revealed between affective commitment and the degree to which before-school physical activity was implemented. More experienced teachers (>20 years) reported significantly higher levels of the work engagement subscale of vigor at posttest. Discussion/Conclusion: Participating in a Comprehensive School Physical Activity Program professional development may positively influence teachers’ job commitment levels and invigorate more experienced teachers, which may relate to Comprehensive School Physical Activity Program implementation.

There appears to be general agreement that interaction with significant challenge should be a central feature of the development pathways for future high performers. There is, however, far less clarity about how such programs should be designed and delivered against core psychological principles. Accordingly, the purpose of this paper is to offer guidelines for talent development practitioners seeking to offer athletes the opportunity to maximize their growth and development. The authors propose that genuinely developmental experiences will likely offer a level of emotional disturbance and, as a result, more fully engage performers, prompting self and other facilitated reflection, and motivate future action. Furthermore, there is a necessity for these experiences and their follow-up, to be managed in a coherent manner and integrated with existing skills, experience, and future performance aims. In highlighting these issues, the authors offer recommendations for talent development coaches, managers, psychologists, and parents of athletes.

Purpose: Guided by the declarative−procedural knowledge framework, the study attempts to identify middle school students’ declarative (knowing what) and procedural (knowing how) fitness knowledge and the relationship between the two. Methods: A sample of students (n = 291, age 11–14 years) from 24 middle schools took a grade-relevant standardized knowledge test on declarative fitness knowledge and received a semistructured interview designed to clarify their declarative and procedural knowledge. Results: Most students were lacking in procedural knowledge to conduct fitness-enhancing physical activities. A few students who had mastered declarative fitness knowledge demonstrated a high level of procedural knowledge consistent with personal fitness goals. Discussion: The findings suggest that incapability to engage in fitness-enhancing physical activities could be a result of lacking procedural fitness knowledge. Future school-based interventions may prioritize procedural knowledge learning for actual physical activity participation.

Coaching is a global profession and coaches play a central role in enhancing the performance of millions of athletes worldwide. In the 21st century, the global mobility of coaches has increased, with many coaches taking advantage of opportunities to coach abroad. Norway leads the all-time Winter Olympics medals table (i.e., 368 medals), and with most of these medals coming from skiing disciplines, Norway represents a skiing hotbed that attracts ski coaches from other parts of the world. The purpose of the study was to examine ski coaches’ motives for and experiences of expatriation to coach in Norway. Five North American alpine ski coaches (four males and one female) were individually interviewed (M = 77 min, SD = 24.94), with the data examined using interpretative phenomenological analysis. Motives for expatriation included having a passion for skiing, challenging oneself, experiencing a new sport culture, and maintaining relationships. Upon arriving in Norway, coaches mentioned experiencing challenges with the Norwegian sport system, language, pressure from parents and the media, and being far from friends and family. Once acclimated, coaches discussed the benefits of expatriation that included the Norwegian work ethic, family-centric lifestyle, and popularity of skiing.

Background: Jumps are important evaluation tools for muscle strength and power and for interlimb asymmetries. Different jump tests are well related to athletic performance, prediction of injury risk, and common motor gestures of several sports such as soccer. Low-cost mobile applications (apps) have gained popularity for this measure. The authors hypothesized that the My Jump 2 app would be a valid tool to assess drop-jump performance and interlimb asymmetry in soccer players. Methods: Eleven male soccer players took part in this study (18.2 [1.3] y, 69.9 [9.5] kg, 174 [6.6] cm). The athletes performed each test twice on a force plate (gold-standard method), while the jumps were recorded through the mobile app. Measures with the My Jump 2 app were applied by 2 evaluators, independently and in duplicate (interrater and intrarater reliability). The agreement analysis between both evaluations was done using an intraclass correlation coefficient and Bland–Altman plots. Results: Compared with the force platform, the app tested showed excellent reliability for the drop jump’s flight time and interlimb asymmetry (intraclass correlation coefficient > .98). For interlimb contact-time asymmetry, the values were 18.4 (9.9) and 19.1 (9.9) milliseconds for the My Jump 2 app and the force platform, respectively (P = .88). For flight-time asymmetries, the values were 389.7 (114.3) and 396.8 (112.5) milliseconds for the My Jump 2 app and the force platform, respectively (P = .88). Conclusion: The My Jump 2 app is a valid tool to assess drop-jump and interlimb asymmetry in soccer players.

Purpose: To replicate previous genome-wide association study identified sprint-related polymorphisms in 3 different cohorts of top-level sprinters and to further validate the obtained results in functional studies. Methods: A total of 240 Japanese, 290 Russians, and 593 Brazilians were evaluated in a case-control approach. Of these, 267 were top-level sprint/power athletes. In addition, the relationship between selected polymorphisms and muscle fiber composition was evaluated in 203 Japanese and 287 Finnish individuals. Results: The G allele of the rs3213537 polymorphism was overrepresented in Japanese (odds ratio [OR]: 2.07, P = .024) and Russian (OR: 1.93, P = .027) sprinters compared with endurance athletes and was associated with an increased proportion of fast-twitch muscle fibers in Japanese (P = .02) and Finnish (P = .041) individuals. A meta-analysis of the data from 4 athlete cohorts confirmed that the presence of the G/G genotype rather than the G/A+A/A genotypes increased the OR of being a sprinter compared with controls (OR: 1.49, P = .01), endurance athletes (OR: 1.79, P = .001), or controls + endurance athletes (OR: 1.58, P = .002). Furthermore, male sprinters with the G/G genotype were found to have significantly faster personal times in the 100-m dash than those with G/A+A/A genotypes (10.50 [0.26] vs 10.76 [0.31], P = .014). Conclusion: The rs3213537 polymorphism found in the CPNE5 gene was identified as a highly replicable variant associated with sprinting ability and the increased proportion of fast-twitch muscle fibers, in which the homozygous genotype for the major allele (ie, the G/G genotype) is preferable for performance.

Purpose: To examine the effect of cycling exercise intensity and duration on subsequent performance and to compare the resulting acute performance decrement (APD) with total work done (TWD) and corresponding training-load (TL) metrics. Methods: A total of 14 male cyclists performed a 5-minute time trial (TT) as a baseline and after 4 initial exercise bouts of varying exercise intensity and duration. The initial exercise bouts were performed in a random order and consisted of a 5- and a 20-minute TT and a 20- and a 40-minute submaximal ride. The resulting APD was calculated as the percentage change in 5-minute TT from baseline, and this was compared with the TWD and TL metrics for the corresponding initial exercise bout. Results: Average power output was different for each of the 4 initial exercise bouts (

There is a growing body of research on positive tactile communication and its impact on athlete performance and team dynamics. The purpose of the present study was to examine the profile and perceived impact of positive tactile communication as a coaching strategy in a high-performance team sport setting. Participants were members of a successful American collegiate women’s basketball team comprising the head coach, associate head coach, and 16 student-athletes. Methods of data collection included systematic observation and focus groups. Positive tactile communication was perceived to be an effective coaching strategy for enhancing relationships and athlete performance. To our knowledge, this is the first study to include both quantitative and qualitative data from multiple coaches on the same team, as well as athlete perceptions of coaches’ strategic use of positive tactile communication.
