Research outputs 2022 to 2026

Introduction:

We tested the hypothesis that muscle damage protection effect would be induced by its antagonist muscle eccentric exercise.

Methods:

Sedentary young (20-28y) men were randomly assigned into six groups; three groups each for arm or leg exercise group (n=12/group). One group performed two bouts of 30 maximal eccentric contractions (30MaxEC) of the elbow flexors (EF) or 60 maximal eccentric contractions (60MaxEC) of the knee flexors (KF) using a different arm (contra-EF-EF) or leg (contra-KF-KF) between bouts. The other two groups performed 30MaxEC of the elbow extensors (EE) or 60MaxEC of the knee extensors (KE) first followed by the 30MaxEC …

In Vivo Human Medial Gastrocnemius Fascicle Behaviour And Belly Gear During Submaximal Eccentric Contractions Are Not Affected By Concentric Fatiguing Exercise, Matheus Daros Pinto, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2022 to 2026

Changes in muscle geometry and belly gearing during eccentric contractions influence fibre strain and susceptibility to muscle damage. They are modulated by the interaction between connective tissues and intracellular-intrafascicular fluid pressures and external pressures from neighbouring structures. Fatiguing exercise triggers fluid shifts (muscle swelling) and muscle activation changes that may influence these modulators. Our purpose was to measure medial gastrocnemius (MG) geometric changes in vivo during eccentric contractions before and after maximal concentric muscle work to test the hypothesis that fatigue would reduce fascicle rotation and muscle gear and provoke greater fascicle strain. Submaximal eccentric plantar flexor contractions at 40% …

Best Practice Recommendations For Coaching Gymnasts To Avoid Burnout And Reframe Performance Anxiety, Clare A. Mccall

Theses: Doctorates and Masters

Gymnastics is deemed a psychologically demanding sport, with associated risk factors of burnout and performance anxiety. To date, relatively little research has explored the specific goal and perfectionistic processes of gymnasts, despite these risks. This body of work identified the specific goal-related constructs and perfectionistic orientation of young athletes and examined how these associated with burnout and performance anxiety. It comprised of two studies with a mixed methods design. The first study aimed to systematically review literature investigating how goal-related constructs and perfectionism associate with burnout and performance anxiety in young athletes. This review focused on summer and winter Olympic …

The Physiological And Performance Consequences Of The Australian Special Forces Selection Course, Angela Uphill

Theses: Doctorates and Masters

Special Forces (SF) soldiers are the most elite element of military forces, who have undergone rigorous training in order to prepare them for a wide array of specialised missions. In Australia, entry into the SF is determined through the highly competitive SF Selection Course (SF-SC), which is a gruelling program involving extreme physical demands, psychological stress, and restricted access to sleep and nutrition. The stressors involved in arduous military training events such as the SF-SC can result in significant losses of fat mass and lean mass, disruption to hormonal homeostasis, and significant decreases in neuromuscular capacity, which can potentially increase …

Resistance Exercise Minimal Dose Strategies For Increasing Muscle Strength In The General Population: An Overview, James L. Nuzzo, Matheus Daros Pinto, Benjamin J. C. Kirk, Kazunori Nosaka

Research outputs 2022 to 2026

Many individuals do not participate in resistance exercise, with perceived lack of time being a key barrier. Minimal dose strategies, which generally reduce weekly exercise volumes to less than recommended guidelines, might improve muscle strength with minimal time investment. However, minimal dose strategies and their effects on muscle strength are still unclear. Here our aims are to define and characterize minimal dose resistance exercise strategies and summarize their effects on muscle strength in individuals who are not currently engaged in resistance exercise. The minimal dose strategies overviewed were: “Weekend Warrior,” single-set resistance exercise, resistance exercise “snacking,” practicing the strength test, …

Error In Jump Height Estimation Using The Flight Time Method: Simulation Of The Effect Of Ankle Position Between Takeoff And Landing, Carlos Gonçalves, Roberto Baptista, James Tufano, Anthony J. Blazevich, Amilton Vieira

Research outputs 2022 to 2026

During vertical jump evaluations in which jump height is estimated from flight time (FT), the jumper must maintain the same body posture between vertical takeoff and landing. As maintaining identical posture is rare during takeoff and landing between different jump attempts and in different individuals, we simulated the effect of changes in ankle position from takeoff to landing in vertical jumping to determine the range of errors that might occur in real-life scenarios. Our simulations account for changes in center of mass position during takeoff and landing, changes in ankle position, different subject statures (1.44–1.98 m), and poor to above-average …

Eccentric Muscle Actions Add Complexity To An Already Inconsistent Resistance Exercise Nomenclature, James L. Nuzzo, Kazunori Nosaka

Research outputs 2022 to 2026

An eccentric muscle action (or contraction) is defined as active muscle lengthening against resistance, which occurs when the force generated by the muscle is smaller than the resistance placed upon it. Eccentric resistance exercise, which involves multiple sessions of repeated eccentric muscle actions, improves muscle strength and other health outcomes. In response to this evidence, new exercise technologies have been developed to permit feasible completion of eccentric muscle actions outside of the laboratory. Consequently, participation in eccentric resistance exercise is projected to increase in the future, and communications about eccentric resistance exercise are likely to reach a wide audience, including …

Thomas, Lewan Parker, Andrew Maiorana, Michelle A. Keske, David Scott, Jennifer L. Reed, Jessica Tieng, Daniel Hackett, Tess Hawkins, Christopher Latella, Rachael Cordina, Derek L. Tran

Research outputs 2022 to 2026

The integration of resistance training for cardiac patients leads to important health outcomes that are not optimally obtained with aerobic exercise; these include an increase in muscle mass, maintenance of bone mineral density, and improvements in muscular fitness parameters. Despite the proliferation of evidence supporting resistance exercise in recent decades, the implementation of resistance training is underutilised, and prescription is often sub-optimal in cardiac patients. This is frequently associated with safety concerns and inadequate methods of practical exercise prescription. This review discusses the potential application of cluster sets to prescribe interval resistance training in cardiac populations. The addition of planned, …

Training For “Worst-Case” Scenarios In Sidestepping: Unifying Strength And Conditioning And Perception–Action Approaches, Daniel Kadlec, Matt Miller-Dicks, Sophia Nimphius

Research outputs 2022 to 2026

Sidesteps can impose high demands on the knee joint and lead to non-contact anterior cruciate ligament (ACL) injuries. Understanding how different constraints shape an athlete’s movement strategy and the associated joint demands can help design training interventions to increase injury resilience. Motor capacities, such as muscular strength and power, act as boundaries for the safe execution of perceptual–motor skills and co-determine the emergence of unique movement strategies. Increasing single- and multi-joint strength enables a broader solution space for movement strategies and increases load tolerance. Manipulating task constraints during sidesteps can be used in the training process to systematically expose athletes …
