Between-Session Reliability And Sensitivity Of Force Production Characteristics Across Various Force-Time Points During The Isometric Single-Leg Long-Lever Bridge, Adam E. Sundh, Nicholas J. Ripley, A. J. Lamb, Conor J. Cantwell, Paul Comfort

Research outputs 2022 to 2026

The purpose of this study was to assess the between-session reliability of peak force and early force-time variables in a unilateral isometric hamstring assessment (isometric long-lever bridge). The sample consisted of 30 collegiate male athletes (age: 19.4±1.3 years; height: 1.79±0.1 m; body mass: 80.4±10.3 kg) with no history of recent hamstring injury (<6 months) who volunteered to participate in the study. All participants performed 3 unilateral maximal voluntary isometric contractions (MVIC) with their heels on force plates and shoulders elevated 15.24 cm, while their hips were secured with a loaded barbell. Data was analyzed to assess the reliability of force values at 50, 100, 150, 200, 250 ms, and peak force (N) across three repeated sessions. Moderate-good relative and absolute reliabilities were observed across all early force-time variables with lower bound ICC values≥0.51 (0.51–0.71) and point estimate CV%≤12.65% (7.63–12.65), with moderate relative (ICC≥0.74; range 0.74–0.92) and absolute (CV%≤6.50%; range 6.48–6.50) reliability for peak force. Trivial to small effect sizes (g≤0.4) were observed between sessions. These findings suggest that the isometric single-leg long-lever bridge (SL-LLB) can be used to reliably monitor peak and rapid force generating capacities to track performance changes over time due to training adaptations as well as acute or chronic fatigue.

Optimizing Agility Training In Team Sport Players—The Role Of Perception-Action Coupling: A Systematic Review With Multi-Level Meta-Analysis, Zhiwei Zhao, Yuhang Liu, Kai Xu

Research outputs 2022 to 2026

Agility, characterized by rapid whole-body movement in response to external stimuli, is a key performance determinant in team sports owing to its reliance on perception-action coupling. Despite its importance, existing evidence on training effects is disproportionately focused on change-of-direction ability, overlooking the perceptual-cognitive demands of true agility. This systematic review therefore sought to quantify the effects of agility-specific training, examine moderators and establish dose-response model in team-sport players, while accounting for perception-action coupling. Following PRISMA 2020 guidelines, systematic searches were conducted in Web of Science, Scopus and PubMed for peer-reviewed English-language studies. Risk of bias was appraised using a modified …

Broadhurst, Thomas Dignan, Jamie Whitfield, Lisa Murray-Segal, Naomi X.Y. Ling, Jonathan S. Oakhill, Bruce E. Kemp, John A. Hawley, Stacey N. Reinke, Nolan J. Hoffman

Research outputs 2022 to 2026

Background/Objectives: Acute exercise remodels many interconnected biochemical pathways in metabolically active tissues. This remodeling involves the activation of the energy-sensing AMP-activated protein kinase (AMPK) to maintain cellular energy homeostasis. Critical energy reserves of glycogen, primarily stored in liver and skeletal muscle and known to interact with AMPK, are utilized to help meet increased energy demands with exercise. However, the breadth of metabolic pathways regulated by acute exercise and AMPK’s interactive roles with glycogen remain incompletely understood. This study therefore aimed to map mouse liver and skeletal muscle metabolite responses to continuous acute exercise and disruption of AMPK-glycogen interactions. Methods: Liquid …

Peak Lower Limb Joint Angles Are Weak Predictors Of Hamstring Length Change During Sprinting, Shayne Vial, Jodie Cochrane Wilkie, Anthony J. Blazevich, Daniel Kadlec

Research outputs 2022 to 2026

Non-contact hamstring injuries (HSIs) commonly occur during the late swing phase of sprinting, when muscle–tendon units (MTUs) approach maximum length. Although sagittal-plane pelvis, hip and knee angles are often used as surrogate measures of overall hamstring lengthening, their predictive validity remains uncertain. This study investigated whether peak three-dimensional lower limb joint angles predict length change in the biarticular hamstring MTUs from peak hip flexion through to toe off (0–100 %) in fourteen intermediate-level male soccer players sprinting at maximal speed (8.56 ± 0.47 m·s−1). Participant-specific musculoskeletal models were used to compute MTU lengths for the biceps femoris long head (BFlh), …

Mckay, Nicolin Tee, Megan L. Ross, Stacey N. Reinke, John A. Hawley, David Broadhurst, Louise M. Burke

Research outputs 2022 to 2026

Periods of low energy availability (LEA) are common in elite athletes and typically arise from reduced energy intake, often involving some degree of carbohydrate (CHO) restriction. Whether the metabolic profile created by energy restriction per se is distinct compared to that driven by CHO restriction is unknown. Using untargeted metabolomics, we examined metabolic perturbations linked to CHO restriction and energy restriction in plasma from elite male endurance athletes. In a semi-randomized controlled trial, athletes (n = 20) completed one of three 5-day dietary interventions: high energy-high CHO (HCHO); LEA (energy-restricted, CHO-reduced); or low-CHO, high-fat (LCHF; energy-matched, CHO-restricted). Plasma samples were …
