The Relationship of Lower-Body, Multijoint, Isometric and Dynamic Neuromuscular Assessment Variables With Snatch, and Clean and Jerk Performance in Competitive Weightlifters: A Meta-Analysis

Quiz

The purpose of this meta-analysis was to synthesize the literature and provide a robust estimate of the correlations between lower-body, multijoint, isometric and dynamic neuromuscular assessment variables and snatch (SN) and clean and jerk (C&J) performance in competitive weightlifters. A comprehensive search through 3 electronic databases (PubMed, SPORTDiscus, and Web of Science) returned 12 studies that met the inclusion criteria. Meta-analyses were performed on Pearson’s correlations between SN and C&J performance and 15 variables from 5 neuromuscular assessments— countermovement jump (CMJ), squat jump (SJ), isometric midthigh pull (IMTP), back squat (BS), and front squat (FS) one repetition maximum (1RM). The FS and BS 1RM exhibited nearly perfect correlations (r 5 0.93 to 0.94), whereas the IMTP peak force exhibited very large correlations (r 5 0.83 to 0.85). The IMTP force at 250 ms exhibited very large correlations (r 5 0.77 to 0.78), and the CMJ and SJ peak power exhibited very large to nearly perfect correlations (r 5 0.88 to 0.92). These findings illustrate the importance of lower-body maximal and time-limited force-producing capabilities in weightlifters. Moreover, each assessment offers at least one variable that exhibits a correlation of .0.70. Therefore, these assessments may be used to gauge weightlifting performance potential.

SCJ 47.5 Managing Fatigue in Team Sports: A Brief Review of Concurrent Training Effects Within the Microcycle

Quiz

Concurrent training (CT), which combines resistance exercise and energy systems conditioning, is the default approach to preparation in high-intensity intermittent (“stop and go”) team sports. This review provides an overview of CT, emphasizing its complexities and challenges in managing fatigue and optimizing performance. These complexities are specifically compounded by the variability in game demands across the season, where the presence of intensified and nonintensified competition periods necessitates a flexible and adaptive training approach. In this context, there are essential training variables to consider, including intensity, volume, session order, and recovery intervals between sessions. In addition, nontraining variables such as travel, sleep, and nutrition play a role in the fatigue experienced while training and competing. These variables interact to influence acute performance and training adaptations and can be strategically adjusted by strength and conditioning practitioners. The aim of this review is to provide a comprehensive understanding of fatigue management for practitioners in team sports, emphasizing the complexities and challenges of CT and offering simplified practical recommendations for adjusting training variables within any given microcycle.

SCJ 48.1 Quantifying Pain: A Methodological Review of Pain Assessment in Exercise Science

Quiz

Exercise is increasingly recognized as an effective, nonpharmacological approach for managing both acute and chronic pain. However, accurate pain assessment methods tailored to different exercise settings and populations are essential. This review evaluates existing pain assessment techniques, highlighting self-report measures such as the Visual Analog Scale and Numerical Rating Scale, as well as quantitative measures, such as Pressure Pain Threshold and Conditioned Pain Modulation. These techniques provide valuable insights into the neurophysiological mechanisms behind pain reduction. Although exercise commonly produces a temporary reduction in pain sensitivity known as exercise-induced hypoalgesia (EIH), the effectiveness of this response depends on various factors, such as exercise intensity, psychological state, and pre-existing pain conditions. In addition, exercise itself can sometimes lead to short-term discomfort due to muscle fatigue or delayed-onset muscle soreness. This review offers strength and conditioning providers, as well as researchers, a clear framework for (a) selecting appropriate pain assessment tools, (b) designing research protocols, and (c) customizing exercise interventions for specific populations and pain conditions. By examining self-report and quantitative assessment techniques, along with considerations for data analysis and practical application, this review helps strength and conditioning professionals interpret the literature surrounding EIH and apply practical pain monitoring strategies to guide training and recovery in various populations.
