Don Hellison (1938–2018) was a leader and trailblazer in sport and physical education pedagogy. Early in his career, he was an advocate for humanistic physical education. His engaged approach to scholarship culminated in the development of the Teaching Personal and Social Responsibility (TPSR) model, which is now recognized as a best practice for promoting social and emotional learning in physical education. The TPSR model has also been widely applied in the field of sport-based youth development. This is the introduction to the special issue devoted to Don’s life and legacy. It provides opening comments from the guest editors and a brief overview of the articles in the special issue.

Although there is burgeoning research on resilience in elite athletes, there has been no empirical investigation of resilience in elite coaches. The purpose of this study was to explore psychological resilience in world-class coaches and how they develop resilience in athletes. A longitudinal qualitative design was adopted due to the dynamic and temporal nature of resilience. Five Olympic medal–winning coaches (four males and one female) were interviewed twice over a 12-month swimming season. Reflexive thematic analysis was employed to analyze the data. Findings revealed 14 higher order themes, which were categorized into the following three general dimensions: coach stressors (managing the Olympic environment, preparation for major events, coach personal well-being, directing an organization); coach protective factors (progressive coaching, coaching support network, maintaining work/life balance, secure working environment, durable motivation, effective decision making); and enhancing resilience in athletes (developing a strong coach–athlete relationship, creating a facilitative environment, developing a resilience process, athlete individual factors). The results are presented to demonstrate the interplay between coach stressors and protective factors over time, which offers an original and significant contribution to the resilience literature by providing a unique insight into the dynamic and temporal nature of resilience in Olympic medal–winning coaches.

Purpose: To quantify, for an elite-level racewalker, altitude training, heat acclimation and acclimatization, physiological data, and race performance from January 2007 to August 2008. Methods: The participant performed 7 blocks of altitude training: 2 “live high:train high” blocks at 1380 m (total = 22 d) and 5 simulated “live high:train low” blocks at 3000 m/600 m (total = 98 d). Prior to the 2007 World Championships and the 2008 Olympic Games, 2 heat-acclimation blocks of ~6 weeks were performed (1 session/week), with ∼2 weeks of heat acclimatization completed immediately prior to each 20-km event. Results: During the observation period, physiological testing included maximal oxygen uptake (VO2max, mL·kg−1·min−1), walking speed (km·h−1) at 4 mmol·L−1 blood lactate concentration [La−], body mass (kg), and hemoglobin mass (g), and 12 × 20-km races and 2 × 50-km races were performed. The highest VO2max was 67.0 mL·kg−1·min−1 (August 2007), which improved 3.1% from the first measurement (64.9 mL·kg−1·min−1, June 2007). The highest percentage change in any physiological variable was 7.1%, for 4 mmol·L−1 [La−] walking speed, improving from 14.1 (June 2007) to 15.1 km·h−1 (August 2007). Personal-best times for 20 km improved from (hh:mm:ss) 1:21:36 to 1:19:41 (2.4%) and from 3:55:08 to 3:39:27 (7.1%) in the 50-km event. The participant won Olympic bronze and silver medals in the 20- and 50-km, respectively. Conclusions: Elite racewalkers who regularly perform altitude training may benefit from periodized heat acclimation and acclimatization prior to major international competitions in the heat.

The authors compared the effectiveness of two modes of daily iron supplementation in athletes with suboptimal iron stores: oral iron (PILL) versus transdermal iron (PATCH). Endurance-trained runners (nine males and 20 females), with serum ferritin concentrations <50 μg/L, supplemented with oral iron or iron patches for 8 weeks, in a parallel group study design. Serum ferritin was measured at baseline and fortnightly intervals. Hemoglobin mass and maximal oxygen consumption (
