Coach Succession and Neuromuscular Warm-Up Delivery in Youth Sport

Abstract

To examine how youth sport clubs can retain neuromuscular warm-up instruction, delivery responsibility and session records when coaches are appointed, absent or replaced. Trial findings, coach questionnaires, interviews, exercise observations and methodological recommendations were examined according to their design, population, denominator and access limitations. The management analysis addressed coach preparation, decision authority, exercise changes and availability of session information. In the Swedish knee-injury trial, 4,564 female football players participated and the anterior cruciate ligament injury rate ratio was 0.36 (95% confidence interval 0.15--0.85). Delivery findings addressed different organisational levels: Chicago school coaches logged warm-up use at 1,425/1,773 practices; 154/178 Swedish current-coach respondents indicated absent or unknown club routines; and 21/62 invited US youth sport organisations implemented an education workshop. These quantities cannot be combined into a single adherence estimate. Coach succession requires transfer of the exercise prescription, accepted teaching responsibility and unresolved technical concerns. Session records distinguish complete, partial, omitted and unknown delivery, while athlete participation and movement quality remain separate assessments. Club management must connect coach appointments with teaching preparation, accessible instructions and responsibility for follow-up. The reviewed investigations establish exercise efficacy and delivery difficulties; they do not quantify the independent injury-prevention effect of a coach handover.
