This study examined whether adolescent athletes’ levels of sport burnout would be predicted by their level and type of both passion and athletic identity. Female high-school-aged athletes (N = 186) completed a series of questionnaires to measure study variables. The results of three hierarchical multiple regression analyses revealed that athletes’ levels of harmonious passion served as negative predictors for all three dimensions of burnout, while obsessive passion positively predicted scores only on the exhaustion subscale. In addition, the subdimensions of athletic identity contributed a unique amount to the prediction of some aspects of burnout. These results indicate that both passion and athletic identity are important correlates or predictors of burnout levels, with harmonious passion offering the most protective effects.

Because there is no single governing sport body in the United States devoted to coaching education, coaching requirements can vary greatly state-to-state and between organizations within the same state. Therefore, it often is up to club programs or universities to devise individual curriculum for coaching education. For those responsible for coaching education, utilizing backwards design can ensure programs meet the learning and professional development needs of coaches. In backwards design, identifying coaches’ needs and creating program-level learning outcomes occurs prior to specific content selection. Additionally, backwards design encourages instructors to select assessments and learning activities that align with the program-level learning outcomes. In this article, a group of faculty describe their experience utilizing backwards design in creating a college/university certificate program focused on sport coaching. Specifically, a description of the following is included: (a) the process used to create program-level learning outcomes, (b) how to emphasize the program-level learning outcomes throughout the program’s coursework, and (c) a specific example from one course in the curriculum. Finally, we provide lessons learned throughout the process and recommendations for program development in hopes that coach developers can utilize this process in designing their own curricula.

Significant social agents are thought to play a vital role in youth development (Brustad, Babkes, & Smith, 2001). The United States Anti-Doping Agency (USADA) commissioned a nationwide survey to examine the effect significant social agents had on youth sport behavior. In Phase I, initial data were collected and results were published in the Journal of Coaching Education (2011). The results of the previous analyses were largely descriptive, and further analyses were desired. Therefore, the current study (Phase II) is a secondary but more in-depth data analysis of the initial data collected by the USADA. Phase II analyses (n = 3379, Mage = 12.23, SD = 2.78) revealed that youth sport coaches have the greatest positive influence on youth followed closely by parents, but all of the significant social agents, to different extents, were seen as more positive than negative by youth. Results varied by developmental level, gender, and competitive level. Results, limitations, and practical implications are discussed.

This study investigated the satisfaction of elite female cyclists with their body weight (BW) in the context of race performance, the magnitude of BW manipulation, and the association of these variables with menstrual function.
Female competitors in the Australian National Road Cycling Championships (n = 32) and the Oceania Championships (n = 5) completed a questionnaire to identify current BW, BW fluctuations, perceived ideal BW for performance, frequency of weight consciousness, weight-loss techniques used, and menstrual regularity.
All but 1 cyclist reported that female cyclists are “a weight-conscious population,” and 54% reported having a desire to change BW at least once weekly; 62% reported that their current BW was not ideal for performance. Their perceived ideal BW was (mean ± SD) 1.6 ± 1.6 kg (2.5% ± 2.5%) less than their current weight (P < .01), and 73% reported that their career-lowest BW was either “beneficial” or “extremely beneficial” for performance. 65% reported successfully reducing BW in the previous 12 months with a mean loss of 2.4 ± 1.0 kg (4.1% ± 1.9%). The most common weight-loss technique was reduced energy intake (76%). Five cyclists (14%) had been previously diagnosed as having an eating disorder by a physician. Of the 18 athletes not using a hormonal contraceptive, 11 reported menstrual dysfunction (oligomenorrhea or amenorrhea).
Elite Australian female cyclists are a weight-conscious population who may not be satisfied with their BW leading into a major competition and in some cases are frequently weight conscious.

Body composition in a female road cyclist was measured using dual-energy X-ray absorptiometry (5 occasions) and anthropometry (10 occasions) at the start of the season (Dec to Mar), during a period of chronic fatigue associated with poor weight management (Jun to Aug), and in the following months of recovery and retraining (Aug to Nov). Dietary manipulation involved a modest reduction in energy availability to 30–40 kcal · kg fat-free mass−1 · d−1 and an increased intake of high-quality protein, particularly after training (20 g). Through the retraining period, total body mass decreased (−2.82 kg), lean mass increased (+0.88 kg), and fat mass decreased (−3.47 kg). Hemoglobin mass increased by 58.7 g (8.4%). Maximal aerobic- and anaerobic-power outputs were returned to within 2% of preseason values. The presented case shows that through a subtle energy restriction associated with increased protein intake and sufficient energy intake during training, fat mass can be reduced with simultaneous increases in lean mass, performance gains, and improved health.

To determine the consistency of commercially available devices used for measuring elevation gain in outdoor activities and sports.
Two separate observational validation studies were conducted. Garmin (Forerunner 310XT, Edge 500, Edge 750, and Edge 800; with and without elevation correction) and SRM (Power Control 7) devices were used to measure total elevation gain (TEG) over a 15.7-km mountain climb performed on 6 separate occasions (6 devices; study 1) and during a 138-km cycling event (164 devices; study 2).
TEG was significantly different between the Garmin and SRM devices (P < .05). The between-devices variability in TEG was lower when measured with the SRM than with the Garmin devices (study 1: 0.2% and 1.5%, respectively). The use of the Garmin elevation-correction option resulted in a 5–10% increase in the TEG.
While measurements of TEG were relatively consistent within each brand, the measurements differed between the SRM and Garmin devices by as much as 3%. Caution should be taken when comparing elevation-gain data recorded with different settings or with devices of different brands.

Some athletes avoid dairy in the meal consumed before exercise due to fears about gastrointestinal discomfort. Regular exclusion of dairy foods may unnecessarily reduce intake of high quality proteins and calcium with possible implications for body composition and bone health. This study compared the effects of meals that included (Dairy) or excluded (Control) dairy foods on gastric comfort and subsequent cycling performance. Well-trained female cyclists (n = 32; mean ± SD; 24.3 ± 4.1 y; VO2peak 57.1 ± 4.9 ml/kg/min) completed two trials (randomized cross-over design) in which they consumed a meal (2 g/kg carbohydrate and 54 kJ/kg) 2 hr before a 90-min cycle session (80 min at 60% maximal aerobic power followed by a 10-min time trial; TT). The dairy meal contained 3 servings of dairy foods providing ~1350 mg calcium. Gut comfort and palatability were measured using questionnaires. Performance was measured as maximum mean power during the TT (MMP10min). There was no statistical or clinical evidence of an effect of meal type on MMP10min with a mean difference (Dairy – Control) of 4 W (95% CI [–2, 9]). There was no evidence of an association between pretrial gut comfort and meal type (p = .15) or between gut comfort delta scores and meal type postmeal (p = .31), preexercise (p = .17) or postexercise (p = .80). There was no statistical or clinical evidence of a difference in palatability between meal types. In summary, substantial amounts of dairy foods can be included in meals consumed before strenuous cycling without impairing either gut comfort or performance.
