Cold Ambient Temperature Does Not Alter Subcutaneous Abdominal Adipose Tissue Lipolysis and Blood Flow in Endurance-Trained Cyclists

Christopher W. Bach, Patrick G. Saracino, Daniel A. Baur, Brandon D. Willingham, Brent C. Ruby, and Michael J. Ormsbee

This study sought to investigate the effect of cold ambient temperature on subcutaneous abdominal adipose tissue (SCAAT) lipolysis and blood flow during steady-state endurance exercise in endurance-trained cyclists. Ten males (age: 23 ± 3 years; peak oxygen consumption: 60.60 ± 4.84 ml·kg−1·min−1; body fat: 18.4% ± 3.5%) participated in baseline lactate threshold (LT) and peak oxygen consumption testing, two familiarization trials, and two experimental trials. Experimental trials consisted of cycling in COLD (3 °C; 42% relative humidity) and neutral (NEU; 19 °C; 39% relative humidity) temperatures. Exercise consisted of 25 min cycling at 70% LT and 25 min at 90% LT. In situ SCAAT lipolysis and blood flow were measured via microdialysis. Heart rate, core temperature, carbohydrate and fat oxidation, blood glucose, and blood lactate were also measured. Heart rate, core temperature, oxygen consumption, and blood lactate increased with exercise but were not different between COLD and NEU. SCAAT blood flow did not change from rest to exercise or between COLD and NEU. Interstitial glycerol increased during exercise (p < .001) with no difference between COLD and NEU. Fat oxidation increased (p < .001) at the onset of exercise and remained elevated thereafter with no difference between COLD and NEU. Carbohydrate oxidation increased with increasing exercise intensity and was greater at 70% LT in COLD compared to NEU (p = .030). No differences were observed between conditions for any other variable. Cycling exercise increased SCAAT lipolysis but not blood flow. Ambient temperature did not alter SCAAT metabolism, SCAAT blood flow, or fat oxidation in well-trained cyclists, though cold exposure increased whole-body carbohydrate oxidation at lower exercise intensities.

Investigating Patterns of Donor and Recipient Sports of Talent Transfer Paralympians

Adeline Green, Rory Mulcahy, David Fleischman, Luke MacDonald, and Bridie Kean

Talent transfer has enabled elite athletes to be successful in another sport, with great potential in para-sport. Previous research suggests that similarities between donor and recipient sports may facilitate talent transfer; however, this remains unclear in para-sport. This study investigated patterns between donor and recipient sports’ characteristics, identifying the impact on talent transfer in para-sport. An Australian case study utilizing secondary data of 38 Australian Paralympians who competed at the Paralympic Games from 2000 through 2020 was analyzed. Results demonstrated that similarities between sports were not significantly associated with successful talent transfers between Paralympic sports. Understanding patterns associated with successful Paralympic talent transfers offers a foundation of knowledge for designing and developing future talent-transfer pathways and research. Based on this study, it is recommended that sport administrators and practitioners explore greater opportunity for talent transfer in para-sport, rather than limiting talent-transfer opportunities based on athletes’ donor sports.

Variability Analysis in Judo Para Athletes With Visual Impairments: Match-Outcome Performance in the Tokyo 2020 Paralympic Games With Evidence From the New Classification System

Rafael Lima Kons, Danilo França Conceição dos Santos, Raiane Carvalho, Adriano Ferreira da Silva, João Paulo Lopes-Silva, Emerson Franchini, and Daniele Detanico

Match-related performance analysis in judo Para athletes with visual impairments is important to coaches and staff to identify technical–tactical profiles of their athletes and opponents but also to identify whether there are similar characteristics in each visual class. Thus, this study explores the match-related performance in judo Para athletes and verifies the relationship between performance using the old and new classification systems. The match-derived variables were analyzed using different statistical methods considering a total of 182 matches from the Tokyo 2020 Paralympic Games. The results indicated that performance was affected by sex and degree of impairment. The new classification system seems suitable for grouping Para judo athletes, as it differentiates performance between the two proposed classes (J1 and J2), since athletes from each group compete separately. Furthermore, different variability index measures were correlated with competitive performance, demonstrating a specific performance profile for each sport class in judo.

A Foucauldian Autoethnographic Account of a Male Former Soccer Player’s Move to Coaching Female Players: A Call to Problematize the Importation of Gendered Assumptions During a Common Coaching Transition

Luke Jones and Zoe Avner

It has frequently been observed that the disproportionate number of male coaches within women’s soccer is problematic, not least, because it limits the opportunities for the progression of female coaches. Despite this, the transition from “male former player to male coach of female players” is one that remains common, is likely to continue, yet is not widely discussed in the sport/coach transition literature. This is an oversight given the numerous problematic outcomes that are routinely connected to the presence of male coaches in women’s sport. In this confessional, analytical autoethnography, we build upon our existing work regarding coaching women’s soccer that has been informed by Michel Foucault’s conceptual framework. Precisely, we use a collection of creative narrative reflections to discuss the first author’s transition from that of a British semiprofessional soccer player context, to an Assistant Coach of a female soccer team in a North American varsity program. In so doing, we trace and map some of the (problematic) learned gendered assumptions which initially shaped and guided the first author’s coaching assumptions, relationships, approaches, and practices within this context, before unpacking some of the challenges he navigated along the way (with varying degrees of success). We end by summarizing our paper and a call to male coaches working with female athletes to reflect on how “thinking with Foucault” might help them to coach in more ethical and gender-responsive ways by both problematizing imported gendered assumptions and developing active allyship practices.

Successful Practices of Novice Urban Physical Education Teachers

Sara B. Flory, Risto Marttinen, Craigory V. Nieman, and Vernise J. Ferrer Lindsay

Purpose: Guided by the cultural relevance cycle, this study examined experiences of two novice physical education teachers in urban schools. We focused on successes that teachers encountered while navigating their novice years. Methods: Two purposefully sampled participants completed five journal entries and five semistructured interviews lasting between 45 and 90 min each. To promote trustworthiness, we utilized multiple coders, a peer debriefer, and triangulated data from multiple sources. Participants reviewed themes and responded to researchers’ interpretations. Results: We present the results through three major themes. The first theme involves knowledge of students and community. The second theme describes belonging in the school and community, and the third theme discusses curricular realignment. Discussion and Conclusion: By focusing on elements that empowered novice teachers to find success, initial teacher preparation programs and in-service teacher mentoring programs in urban school districts might identify teaching experiences that may contribute to novice teacher retention.

Monitoring Readiness to Train and Perform in Female Football: Current Evidence and Recommendations for Practitioners

Marco Beato, Esben Elholm Madsen, Jo Clubb, Stacey Emmonds, and Peter Krustrup

Purpose: Monitoring player readiness to train and perform is an important practical concept in football. Despite an abundance of research in this area in the male game, to date, research is limited in female football. The aims of this study were, first, to summarize the current literature on the monitoring of readiness in female football; second, to summarize the current evidence regarding the monitoring of the menstrual cycle and its potential impact on physical preparation and performance in female footballers; and third, to offer practical recommendations based on the current evidence for practitioners working with female football players. Conclusions: Practitioners should include both objective (eg, heart rate and countermovement jump) and subjective measures (eg, athlete-reported outcome measures) in their monitoring practices. This would allow them to have a better picture of female players’ readiness. Practitioners should assess the reliability of their monitoring (objective and subjective) tools before adopting them with their players. The use of athlete-reported outcome measures could play a key role in contexts where technology is not available (eg, in semiprofessional and amateur clubs); however, practitioners need to be aware that many single-item athlete-reported outcome measures instruments have not been properly validated. Finally, tracking the menstrual cycle can identify menstrual dysfunction (eg, infrequent or irregular menstruation) that can indicate a state of low energy availability or an underlying gynecological issue, both of which warrant further investigation by medical practitioners.
