Purpose: To examine the relationship between the maximal power output (MPO) in an individualized 7 × 2-minute incremental (INCR) test, average power in a 2k (W2k) rowing ergometer test, and maximal oxygen uptake (V˙O2max) and to develop a regression equation to predict V˙O2max. Methods: A total of 34 male club rowers (age 18–30 y) performed a 2k and an INCR test in a Concept2 rowing ergometer to determine and compare MPO, W2k, and V˙O2max. Results: No significant difference was found between V˙O2max measured during INCR or 2k test (P = .73). A very high correlation coefficient (r = .96) was found between MPO and V˙O2max and between W2k and V˙O2max (r = .93). Linear regression analyses were developed for predicting V˙O2max from MPO: (1) V˙O2max (mL·min−1) = 11.49 × MPO + 810 and V˙O2max from W2k: (2) V˙O2max = 10.96 × W2k + 1168. Cross-validation analyses were performed using an independent sample of 14 rowers. There was no difference between the mean predicted V˙O2max in the INCR test (4.41 L·min−1) or the 2k test (4.39 L·min−1) and the observed V˙O2max (4.40 L·min−1). Technical error of measurement was 3.1% and 3.6%, standard error of estimate was 0.136 and 0.157 mL·min−1, and validation coefficients (r) were .95 and .94 using Equation () and (), respectively. Conclusion: A prediction model only including MPO or W2k explains 88% to 90% of the variability in V˙O2max and is suggested for practical use in male club rowers.

Purpose: This study examined the maintenance of passing performance following soccer-specific high-intensity intermittent exercise in elite (n = 9) and subelite (n = 11) Western Australian female soccer players (19.5 [2.5] y). Methods: A total of 20 participants completed the Loughborough Soccer Passing Test (LSPT) prior to, during, and following 90 minutes of a modified, female-specific, individualized exercise protocol (Loughborough Intermittent Shuttle Test [LIST]) to simulate 2 halves of a soccer match. Performance in the LSPT was calculated by adding “raw time” to the accumulated “penalty time” for each test. Results: Elite players recorded greater distances (t 58 = 4.671, P < .001, effect size [ES] = 1.21) and higher derived VO2max values (t 58 = 4.715, P < .001, ES = 1.20) for the LIST exercise protocol over the subelite players. The total performance times for each LSPT were longer in the subelites in comparison with the elites, with a very large ES difference seen in post-LIST1 (t 18 = −6.64, P < .001, ES = 2.99) and post-LIST2 (t 18 = −9.143, P < .001, ES = 4.12). No between-groups differences were identified for “raw time” at any time point. Hence, all reported LSPT performance differences are attributed to “penalty time.” Conclusion: These data suggest that elite players can sustain their passing performance more efficiently throughout match play that can subelite female soccer players. These findings may contribute to future talent-identification testing by helping to distinguish between elite- and subelite-level players through sustained passing performance. Coaches may also use this information to better inform best-practice training methods through modification of male soccer-specific high-intensity intermittent exercise to a female cohort.

The purpose of this article is to describe the evolution and influence of Masters Player-Coaches (MPCs) in the Asociación de Futbolistas Adultos Mayores del Tolima (in English: Masters Athletes’ Football Association of Tolima in Colombia, South America), a football league for men aged 60–70+ years. Historical forces shape a cultural backdrop that pervades football (soccer) and coaching and provides an understanding of how MPCs perceive themselves. After exploring the evolution and influence of the league, the authors uncover a peer-coaching approach in Asociación de Futbolistas Adultos Mayores del Tolima, described by the MPCs as Compañero Orientador. The authors link the importance of formally acknowledging the MPCs with their influence in fighting ageism, community building, and promoting lifelong sport. Further, MPCs provide high-quality Masters sport experiences, and their recognition supports a formal sporting structure in applying for local government grants to support the growing Masters context in Colombia.

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.
