Negative or evenly paced racing strategies often lead to more favorable performance outcomes for endurance athletes. However, casual inspection of race split times and observational studies both indicate that elite triathletes competing in Olympic-distance triathlon typically implement a positive pacing strategy during the last of the 3 disciplines, the 10-km run. To address this apparent contradiction, the authors examined data from 14 International Triathlon Union elite races over 3 consecutive years involving a total of 725 male athletes. Analyses of race results confirm that triathletes typically implement a positive running pace strategy, running the first lap of the standard 4-lap circuit substantially faster than laps 2 (∼7%), 3 (∼9%), and 4 (∼12%). Interestingly, mean running pace in lap 1 had a substantially lower correlation with 10-km run time (r = .82) than both laps 2 and 3. Overall triathlon race performance (ranking) was best associated with run performance (r = .82) compared with the swim and cycle sections. Lower variability in race pace during the 10-km run was also reflective of more successful run times. Given that overall race outcome is mainly explained by the 10-km run performance, with top run performances associated with a more evenly paced strategy, triathletes (and their coaches) should reevaluate their pacing strategy during the run section.

This case study examines the personal experiences of an elite athlete, coach, and sport psychology consultant (SPC) during the athlete’s preparation and performance in a recent Olympic Games. The qualitative research details how the consultancy process was affected by the athlete’s late admission of the deteriorating relationship with his coach. The concepts of closeness, commitment, complementarity, and co-orientation provided a theoretical perspective to the SPC’s interpretation of athlete performance and the interpersonal conflict that developed between athlete and coach. The basic performance demand model provided an applied perspective. The SPC’s commentary adopts a reflexive discursive style that also focuses on the SPC’s role in the consultancy process and the effectiveness of the performance demand model materials. Five important recommendations arise from the case study, and these might inform other SPCs’ future athlete–coach consultancies and interventions.

Context: Capsaicinoids and capsinoids (CAP) are natural substances found primarily in chili peppers and other spicy foods that agonize the transient receptor potential vanilloid-1 in the mouth, stomach, and small intestine. Several studies have shown CAP to be a potential antiobesity agent and to exhibit an analgesic effect in both rodents and humans. However, there is no scientific consensus about the effects of CAP on physical exercise performance and its physiological mechanisms of action. Purpose: This systematic review aimed to better elucidate the effects of CAP compounds as ergogenic aids and to discuss underlying mechanisms of action by which this supplement may potentially enhance endurance performance and muscular strength. Conclusions: Among 22 studies included in the review, 14 examined the effects of capsaicinoid or capsinoid compounds on endurance and resistance exercise performance in animals, with 9 studies showing benefits on performance. In humans, 8 studies were included: 3 demonstrated significant acute endurance benefits and 2 showed acute resistance exercise performance benefits compared with a placebo condition. Therefore, while more mechanistic studies are necessary to confirm these outcomes in humans, the available scientific literature appears to suggest that these compounds could be considered an effective nutritional strategy to improve exercise performance.

Aim: To provide insight into how physical education teachers use discursive resources related to obesity to create particular professional identities. Method: Data come from focus group and individual interviews with physical education teachers in Sweden. Discourse theory on teacher identities frame the analysis of the empirical material. Results: Data suggest that teachers in Sweden make use of six distinct but related discursive contributions to produce three professional identities: the caring practitioner, an identity concerned with ensuring all pupils irrespective of size participate in physical education; the activity luminary, an identity that focuses on inspiring pupils toward activity across the lifespan, and; the body rationalist, an identity concerned with challenging unrealistic media discourses and reassuring pupils that they have “normal” bodies. Discussion: The identities appear more inclusive, sensitive, and critical than current physical education literature on obesity suggests, however they also contain elements that are fundamentally unsympathetic to overweight individuals.
