Hamstrings Force-Length Relationships And Their Implications For Angle-Specific Joint Torques: A Narrative Review, Eleftherios Kellis, Anthony J. Blazevich

Research outputs 2022 to 2026

Temporal biomechanical and physiological responses to physical activity vary between individual hamstrings components as well as between exercises, suggesting that hamstring muscles operate differently, and over different lengths, between tasks. Nevertheless, the force-length properties of these muscles have not been thoroughly investigated. The present review examines the factors influencing the hamstrings’ force-length properties and relates them to in vivo function. A search in four databases was performed for studies that examined relations between muscle length and force, torque, activation, or moment arm of hamstring muscles. Evidence was collated in relation to force-length relationships at a sarcomere/fiber level and then moment …

Metabolomics Reveals Mouse Plasma Metabolite Responses To Acute Exercise And Effects Of Disrupting Ampk-Glycogen Interactions, Mehdi R. Belhaj, Nathan G. Lawler, John A. Hawley, David I. Broadhurst, Nolan J. Hoffman, Stacey N. Reinke

Research outputs 2022 to 2026

Introduction: The AMP-activated protein kinase (AMPK) is a master regulator of energy homeostasis that becomes activated by exercise and binds glycogen, an important energy store required to meet exercise-induced energy demands. Disruption of AMPK-glycogen interactions in mice reduces exercise capacity and impairs whole-body metabolism. However, the mechanisms underlying these phenotypic effects at rest and following exercise are unknown. Furthermore, the plasma metabolite responses to an acute exercise challenge in mice remain largely uncharacterized. Methods : Plasma samples were collected from wild type (WT) and AMPK double knock-in (DKI) mice with disrupted AMPK-glycogen binding at rest and following 30-min submaximal treadmill …

The Reliability And Magnitude Of Time-Dependent Force-Time Characteristics During The Isometric Midthigh Pull Are Affected By Both Testing Protocol And Analysis Choices, Stuart N. Guppy, Yosuke Kotani, Claire J. Brady, Shannon Connolly, Paul Comfort, Gregory G. Haff

Research outputs 2022 to 2026

This study aimed to investigate whether the use of short-duration (SHORT) isometric midthigh pull (IMTP) trials resulted in greater reliability and magnitude of time-dependent force-time characteristics than traditionally performed IMTP trials (TRAD). Fourteen subjects with > 6 months' training experience with the power clean volunteered to take part in the study. Subjects performed five ∼1-second IMTP trials (SHORT) and five 5-second IMTP trials (TRAD). SHORT resulted in substantially more reliable rate of force development (RFD) measures (intraclass correlation coefficient [ICC] = 0.97–0.99; coefficient of variation [CV] = 2.6–7.0%), particularly during time bands from force-onset to 150 ms, compared with TRAD when …

Shorter Constant Work Rate Cycling Tests As Proxies For Longer Tests In Highly Trained Cyclists, Chantelle Du Plessis, Mark Andrews, Lachlan J. G. Mitchell, Jodie Cochrane Wilkie, Trish King, Anthony J. Blazevich

Research outputs 2022 to 2026

Severe-intensity constant work rate (CWR) cycling tests simulate the high-intensity competition environment and are useful for monitoring training progression and adaptation, yet impose significant physiological and psychological strain, require substantial recovery, and may disrupt athlete training or competition preparation. A brief, minimally fatiguing test providing comparable information is desirable.

Purpose

To determine whether physiological variables measured during, and functional decline in maximal power output immediately after, a 2-min CWR test can act as a proxy for 4-min test outcomes.

Methods

Physiological stress (VO _2 kinetics, heart rate, blood lactate concentrations ([La-]b)) was monitored and performance fatigability was estimated (as pre-to-post-CWR …

Dietary Iron And The Elite Dancer, Caitlin Attwell, Cory Dugan, Alannah K. A. Mckay, Joanna Nicholas, Luke Hopper, Peter Peeling

Research outputs 2022 to 2026

Dancers are an athlete population at high risk of developing iron deficiency (ID). The aesthetic nature of the discipline means dancers potentially utilise dietary restriction to meet physique goals. In combination with high training demands, this means dancers are susceptible to problems related to low energy availability (LEA), which impacts nutrient intake. In the presence of LEA, ID is common because of a reduced mineral content within the low energy diet. Left untreated, ID becomes an issue that results in fatigue, reduced aerobic work capacity, and ultimately, iron deficient anaemia (IDA). Such progression can be detrimental to a dancer’s capacity …

Effects Of Reciprocal Inhibition And Whole-Body Relaxation On Persistent Inward Currents Estimated By Two Different Methods, Ricardo N.O. Mesquita, Janet L. Taylor, Gabriel S. Trajano, Jakob Škarabot, Aleš Holobar, Basílio A. M. Gonçalves, Anthony J. Blazevich

Research outputs 2022 to 2026

Persistent inward currents (PICs) are crucial for initiation, acceleration, and maintenance of motoneuron firing. As PICs are highly sensitive to synaptic inhibition and facilitated by serotonin and noradrenaline, we hypothesised that both reciprocal inhibition (RI) induced by antagonist nerve stimulation and whole-bodyrelaxation (WBR) would reduce PICs in humans. To test this, we estimated PICs using the well-established paired motor unit (MU) technique. High-density surface electromyograms were recorded from gastrocnemius medialis during voluntary, isometric 20-s ramp, plantarflexor contractions and decomposed into MU discharges to calculate delta frequency (ΔF). Moreover, another technique (VibStim), which evokes involuntary contractions proposed to result from PIC …

The Current State Of Subjective Training Load Monitoring: Follow-Up And Future Directions, Joseph O. C. Coyne, Aaron J. Coutts, Robert U. Newton, Gregory G. Haff

Research outputs 2022 to 2026

This article addresses several key issues that have been raised related to subjective training load (TL) monitoring. These key issues include how TL is calculated if subjective TL can be used to model sports performance and where subjective TL monitoring fits into an overall decision-making framework for practitioners. Regarding how TL is calculated, there is conjecture over the most appropriate (1) acute and chronic period lengths, (2) smoothing methods for TL data and (3) change in TL measures (e.g., training stress balance (TSB), differential load, acute-to-chronic workload ratio). Variable selection procedures with measures of model-fit, like the Akaike Information Criterion, …

Modulating Tumour Hypoxia In Prostate Cancer Through Exercise: The Impact Of Redox Signalling On Radiosensitivity, Malcolm Brown, Amélie Rébillard, Nicolas H. Hart, Dominic O’Connor, Gillian Prue, Joe M. O’Sullivan, Suneil Jain

Research outputs 2022 to 2026

Prostate cancer is a complex disease affecting millions of men globally. Radiotherapy (RT) is a common treatment modality although treatment efficacy is dependent upon several features within the tumour microenvironment (TME), especially hypoxia. A hypoxic TME heightens radioresistance and thus disease recurrence and treatment failure continues to pose important challenges. However, the TME evolves under the influence of factors in systemic circulation and cellular crosstalk, underscoring its potential to be acutely and therapeutically modified. Early preclinical evidence suggests exercise may affect tumour growth and some of the benefits drawn, could act to radiosensitise tumours to treatment. Intracellular perturbations in skeletal …

Research outputs 2022 to 2026

The countermovement jump (CMJ) has been suggested to be an important test of neuromuscular performance for rugby league (RL) players. Identifying force platform-derived CMJ variables that may be more applicable to RL positions (e.g., forwards and backs) has yet to be fully explored in the scientific literature. The aim of this study was to identify RL position-specific CMJ force-time variables. Specifically, we aimed to compare select forcetime variables from the countermovement (i.e., the combination of unweighting and braking) and propulsion phases of the CMJ between the global forwards and backs positional groups. We also aimed to compare typical (i.e., jump …
