An exploratory survey of the application of accentuated eccentric loading in resistance training

The aim of this study was to investigate how accentuated eccentric loading (AEL) is currently utilised by strength and conditioning (S&C) coaches. The survey consisted of closed- and open-ended questions divided into 3 key areas of focus (1-Coach and Athlete Demographic, 2-Perceptions of AEL, and 3-Program Design) was administered to S&C coaches. Response frequencies for sections 1 and 2 were calculated as percentages of total respondents, whereas frequencies in Section 3 were calculated relative to respondents who selected each specific training purpose. A thematic analysis was conducted for the responses to an open-ended question. A total of 38 respondents met the inclusion criteria and completed the survey. Twenty-three (age: 38.9 ± 13.6 years) reported having previously prescribed AEL with resistance training, while 15 (age: 34.7 ± 8.0 years) did not. Respondents most frequently learned about AEL from S&C experts (83%), academic journals (83%), and S&C colleagues (65%). Limited equipment access (60%), supervision issues associated with large athlete cohorts (33%), inappropriate athlete populations (33%), and lack of full knowledge about this training method (33%) were identified as the main barriers preventing non-users from integrating AEL into their resistance training programs. AEL was reported to be primarily applied to athletes involved in team sports (65%), weightlifting/powerlifting (30%), and track and field (22%), most of whom were younger than 30 years and had substantial resistance training experience. AEL was most frequently implemented with the back squat (83%) with a primary goal of enhancing maximal strength (84%) and/or power output (74%). Further practical and evidence-based information on how to safely and effectively apply AEL for different training purposes is warranted to guide practice.
