Abstract
Background: Ultra-short race-pace training (USRPT) is designed to accustom swimmers to the pace of an event by using high volume and submaximal intensity with short intervals. However, due to imprecise data on volume and interval, further investigation is necessary. This scoping review aims to provide evidence-based insights into the advantages and disadvantages of recommended volumes and intervals during USRPT, guiding swimming coaches and offering practical advice regarding this training method. Methods: For this analysis, 90,613 studies from PubMed, Scopus, Web of Science, and Google Scholar were screened to examine the volume and interval of the USRPT method. Results: Only five studies met the inclusion criteria, were further assessed using a PRISMA-P document, and were analyzed for biases with the revised Cochrane risk-of-bias tool for randomized crossover trials. Excessive daily use of USRPT in training volume is discouraged due to potential psychological strain. Reaching failure should involve modifying variables such as intensity and interval. Additionally, interval periods should vary based on the targeted event’s physiological demands and the USRPT set’s volume. For short-distance events (50–100 m), it is recommended that USRPT protocols include a work-to-rest ratio of 1:1 or 1:2, allowing more time for aerobic contribution to replenish energy supplies (consistent with HIIT and SIIT principles). Conclusions: Further research on specific elements of USRPT, including volume and interval, is essential to identify the most effective training sets for swimmers across different distances and styles.
