Optimal Support for Elite Sprinters Using a Minimal, Adequate, and Accurate Approach

Jad Adrian Washif and David B. Pyne

Background: In high-performance sport, the support provided by sport scientists and other staff can be a valuable resource for coaches and athletes. Purpose: We propose and detail here the approach of “minimal, adequate, and accurate” sport-science support to ensure that programs of work and solutions are both economical and effective. Methods: Our support provision advocates for utilization of “minimal” resources (employing the least amount of time, tools, and funding) necessary to achieve the desired outcomes. We strive for “adequate” information that fulfills specific objectives without excess and with the requirement that methods and data used are “accurate” (valid and reliable). To illustrate the principles of this approach, we outline a real-world example of supporting 100-m track (athletics) sprinters preparing and competing in an international competition. The provision of performance support emphasizes an integrated approach, combining knowledge and insights from multiple sport-science disciplines. The key facets managed under this approach are (1) neuromuscular readiness, (2) wellness monitoring, (3) movement observation, (4) motivation, (5) biomechanics and performance analysis, and (6) qualitative feedback. These facets are based on the specific performance determinants and influencing factors of an event (100-m dash). Conclusions: Application of this quantitative and qualitative approach can enhance the ability to make informed decisions. Nevertheless, the approach must be planned, evaluated, and refined on a regular basis to enable effective decision making in sport-science support. The 3-element approach of “minimal, adequate, and accurate” should be codesigned and supported by the athletes, coaches, and staff to ensure successful implementation.

Training-Load Management Ambiguities and Weak Logic: Creating Potential Consequences in Sport Training and Performance

Stephen West, Ian Shrier, Franco M. Impellizzeri, Jo Clubb, Patrick Ward, and Garrett Bullock

Background: The optimization of athlete training load is not a new concept; however in recent years, the concept of “load management” is one of the most widely studied and divisive topics in sports science and medicine. Purpose: Discuss the challenges faced by sports when utilizing training load monitoring and management, with a specific focus on the use of data to inform load management guidelines and policies/mandates, their consequences, and how we move this field forward. Challenges: While guidelines can theoretically help protect athletes, overzealous and overcautious guidelines may restrict an athlete’s preparedness, negatively influence performance, and increase injury risk. Poor methods, wrong interpretation of study findings, and faulty logic do not allow for systematic scientific evaluations to inform guidelines. Practical Solutions: Guidelines and mandates should be developed through a systematic research process with stronger research designs and clear research questions. Collaborating with statistical and epidemiological experts is essential. Implementing open science principles and sharing all sports training load data increase transparency and allow for more rapid and valid advancements in knowledge. Practitioners should incorporate multiple data streams and consider individual athlete responses, rather than applying broad guidelines based on average data. Conclusion: Many current training load guidelines and mandates in sports come from good intentions; however, they are arbitrary without sound knowledge of the underlying scientific principles or methods. Common sense guidelines are helpful when there is sparse literature, but they should be careful to avoid arbitrarily choosing findings from weak research. Without precise scientific inquiries, implementing training load interventions or guidelines can have negative implications.

Antidoping 2.0: Is Adding Power-Output Data to the Antidoping Pool the Next Step? Experts’ Viewpoint

Sebastian Sitko, Pedro Valenzuela, Nathan Townsend, Marco Pinotti, Mikel Zabala, Xabier Artetxe, Gabriele Gallo, Manuel Mateo-March, Dajo Sanders, Frédéric Grappe, David C. Clarke, Teun van Erp, and Aitor Viribay

Background: Efforts are needed to improve antidoping procedures. The widespread use of power meters among cyclists could help in this regard. However, controversy exists on whether performance monitoring through power-output data could be of help for antidoping purposes. Purpose: The objective of the present study was to provide insight into the feasibility and utility of implementing power-based performance monitoring in elite cycling. An expert panel of 15 applied sport scientists and professional cycling coaches were asked for their opinions and perspectives on incorporating power data into the antidoping risk-assessment process. Results: Two different viewpoints were identified from the responses provided by the experts. Some believed that power monitoring could be implemented as an antidoping tool, provided that several surmountable challenges are first addressed. These authors provided suggestions related to the potential practical implementation of such measures. Others, on the contrary, believed that power meters lack sufficient reliability and suggest that the professional cycling world presents conflicts of interest that make this intervention impossible to implement nowadays. Conclusions: The debate around the utility of power-meter data in the antidoping fight has been ongoing for more than a decade. According to the opinions provided by the experts’ panel, there is still no consensus on the real utility and practical implementation of this intervention.

APAQ at Forty: Publication Trends

Jeffrey J. Martin

The purpose of the present study was to analyze Adapted Physical Activity Quarterly (APAQ) publications over the journal’s fourth decade (2014–2023) and compare them with previous documentary analyses of the first 3 decades. Consistent with prior documentary analyses, publications were coded and analyzed based on the use of theory, research participants, topic, whether the study was an intervention, first-author country affiliation, and research method. The total number of published research papers increased substantially (n = 61) from the third to the fourth decade. Similar to prior documentary analyses, most of the research was quantitative (n = 140; 57.5%), followed by qualitative research (n = 96; 39.5%). There were far more qualitative-research publications in the fourth decade compared with the third decade (n = 34). This may reflect the continued acceptance and growth of qualitative research compared with 10–20 years ago. It may also reflect the value of rich in-depth exploratory research using small samples. Additional trends included more review papers and meta-analyses, possibly reflecting the increased knowledge base in particular areas requiring synthesis. The diversity of topics also increased, with papers on dignity, classification, coaching, and the Paralympics playing more prominent roles. The number of international publications also grew substantially. In brief, the current paper outlines both similarities and differences in APAQ’s published research over the 4 decades of its existence.

Female Athlete Sport Science Versus Applied Practice: Bridging the Gap

Richard J. Burden, Anita Biswas, and Anthony C. Hackney

Background: Female-specific science, medicine, and innovation have grown steadily since the turn of the decade as the focus on female sport continues to advance. While this growth is welcome, and despite the best of intentions, it is not always coupled with valuable application. Purpose: This commentary discusses barriers faced when developing and applying sport-science research and innovation activities in female sport. We offer several practical solutions to help safeguard the progress of female athlete health and performance support. We make 3 suggestions: (1) multicenter studies to increase the number of elite athletes participating in research and enhance statistical power, which is often lacking in sport-science research; (2) further acceptance of case studies in elite sport research, as they can include context alongside athlete data that more traditional research designs perhaps do not; and (3) collaborative, codesigned approaches to research and innovation, wherein researchers, practitioners, and athletes all contribute to balancing scientific rigor with applied “real-world” understanding, which may result in the generation of richer, more meaningful knowledge for the benefit of female athletes and their environments.

Pacing Demands in Competitive Nordic Skiing

Thomas Losnegard, Jan Kocbach, and Øyvind Sandbakk

Background and Purpose: Cross-country skiing, biathlon, and Nordic combined are Winter Olympics sports that involve cross-country skiing in undulating terrain, characterized by various subtechniques and repeated intensity fluctuations. The stochastic interval profile of these sports necessitates the continuous regulation of work and energy expenditure throughout training sessions and competitions, a concept known as pacing. With the advent of technological advancements that allow for the measurement of these features during training and competitions, scientific studies have broadened our understanding of the associated racing and pacing demands. We provide the current scientific overview of pacing demands in competitive cross-country skiing, biathlon, and Nordic combined and propose guidelines for how performance can be enhanced by adjusting pacing behavior. Conclusions and Practical Applications: The study of pacing in skiing has evolved from basic lap-to-lap, or segment, analyses to detailed insights into micropacing strategies. This includes analysis of speed, internal and external power, subtechnique distribution, and associated temporal patterns, combined with subjective ratings of effort. While several objective tools such as heart rate, blood lactate concentration, and speed measurements are widely used in practice, current understanding suggests that these measures should supplement, rather than replace, the use of perceived effort (eg, rating of perceived exertion) to regulate intensity during training and competition in undulating terrain. Therefore, the ability to self-regulate effort appears to be an important performance characteristic and should be developed in adolescents and systematically used to optimize and evaluate the training process and race performance throughout athletes’ careers.

Oral but Not Topical Sodium Bicarbonate Improves Repeated Sprint Performance During Simulated Soccer Match Play Exercise in Collegiate Athletes

William H. Gurton, Lewis A. Gough, Jason C. Siegler, Anthony Lynn, and Mayur K. Ranchordas

This study investigated the effect of oral and topical sodium bicarbonate (SB) on soccer-specific performance during simulated soccer exercise. In a block randomized, double-blind, crossover design, 10 collegiate male soccer players (stature: 181.7 ± 3.2 cm, body mass: 81.7 ± 10.5 kg) performed soccer-specific performance tests (countermovement jumps, Illinois agility, 8 × 25 m repeated sprints) throughout a 90-min soccer-specific aerobic field test (SAFT90) following 0.3 g/kg body mass SB in capsules (SB-ORAL), 0.9036 g/kg body mass PR Lotion (SB-LOTION), or placebo capsules and lotion (PLA). Soccer-specific performance tests were conducted pre-SAFT90, during half-time and post-SAFT90. Blood samples were analyzed for acid–base balance (pH; bicarbonate, HCO 3 ) and strong ions (sodium, Na+; potassium, K+). Average sprint times were quicker for SB-ORAL than PLA during half-time (3.7%; p = .049; g = .57) and post-SAFT90 (4.9%; p = .041; g = .66). SB-ORAL increased pH and HCO 3 prewarm-up and during half-time (p < .05), and lowered K+ during half-time (p = .035) compared with PLA. SB-LOTION increased pH (p = .019) and lowered K+ (p = .012) during half-time compared with PLA. SB-LOTION increased Na+ postexercise compared with PLA (p = .008). Repeated sprint times during simulated soccer exercise improved for SB-ORAL, which might have been mechanistically underpinned by elevated blood buffering capacity and greater regulation of strong ion concentration. Consuming SB in capsules is a more effective strategy than topical SB application for improving blood buffering capacity and repeated sprint performance throughout competitive soccer matches.

Influencers de la Educación Física en Instagram: el Engranaje entre Conocimiento Experto, Estrategias de Microcelebridad y Funcionalidades de la Plataforma

Alejandro Alcolea Lozano and Maria José Camacho-Miñano

Purpose: This study analyses the role of Physical Education (PE) teachers who are influencers on the Instagram social network. Method: Using a descriptive case study, the profiles of three Spanish PE influencers were analysed for seven months (159 posts and 73 stories) with a thematic analysis. Results: The results show that the PE influencer is the product of a complex interplay in which the dissemination of their knowledge and their identity as experts is developed through microcelebrity strategies and the management of the functionalities of the platform itself aimed at boosting their visibility and, ultimately, monetising their content. Conclusion: It concludes with the tensions that exist for PE around this phenomenon within the neoliberal educational context and the need for teacher training to be adapted to this new educational reality.

Evaluación de una propuesta educativa en Educación Física para promocionar la bicicleta como modo de transporte al centro educativo en adolescentes: Estudio PACO

Javier Molina-García, Francisco Javier Huertas-Delgado, Pablo Campos-Garzón, and Palma Chillón

Purpose: To analyze the effects of an educational proposal in Physical Education to promote cycling as a mode of transport to school. Method: The PACO study (‘Pedalea y Anda al Cole’) is a randomized controlled trial. Satisfaction with the sessions, cycling skills and knowledge, mode of travel, basic psychological needs and barriers to active commuting were assessed. Results: There was a high satisfaction with the sessions, an adequate development of cycling skills and an improved knowledge of traffic rules and cycling behavior. There was a significant decrease in the satisfaction of the need of competence and an increase in the perception of barriers in the intervention group compared to the control group. There was no change in the mode of transport. Conclusion: This type of educational proposals should be developed during more sessions and/or through interdisciplinary center projects to achieve positive and lasting behavioral changes.
