Summary: Abstract: Velocity-based training (VBT) utilizes velocity to prescribe and monitor training sessions and to assess fatigue status, as well as to estimate one-repetition maximum (1RM) loads. However, most studies have focused on physically active and trained individuals, revealing that training status directly influences mean velocity (MV). Despite this relevance, there is a scarcity of investigations exploring the application of VBT specifically in powerlifting athletes. Consequently, the aim of this dissertation was to analyze studies that employed VBT in powerlifting athletes, as well as to individually investigate the linear regression method for estimating 1RM loads in the squat, bench press, and deadlift exercises. To achieve these objectives, Article 1 presents a review providing an overview of the use of VBT in the context of powerlifting. The literature search was conducted using the MEDLINE database via EBSCO and SCOPUS, utilizing search terms related to VBT and powerlifting, including studies with male and female powerlifting athletes. Article 2 aimed to evaluate the efficacy of the linear regression method for powerlifting athletes. The study involved four athletes (three men and one woman) with relative strength in the squat (2.57 ± 0.5), bench press (1.41 ± 0.42), and deadlift (2.6 ± 0.49), who competed between 2022 and 2024, with a minimum training frequency of three times per week. Participants performed a 1RM test for the squat, bench press, and deadlift, with each movement tested on a separate day, allowing for a one-week interval between tests. The sessions were organized as follows: Session 1: squat; Session 2: bench press; Session 3: deadlift. A progressive test was conducted, starting at 40%-1RM and progressing to 100%-1RM, with a 10% increase in each set. Velocity was measured in each set using a linear transducer attached to the bar. Data analysis included a normality test, followed by simple linear regression to estimate 1RM loads. Results: In Article 1, a total of 9 studies were analyzed. Article 2 demonstrated very high load-velocity relationships for determining loads through velocity using the linear regression method, with r2 > 0.8 and p < 0.05 across all exercises. In conclusion, the results from both articles suggest the efficacy of linear regression for estimating 1RM loads in powerlifting athletes, as well as a positive impact of VBT during training sessions, aiding in the monitoring of athlete fatigue and recovery status.
