Greater Strength Gains After Training With Accentuated Eccentric Than Traditional Isoinertial Loads In Already Strength-Trained Men, Simon Walker, Anthony J. Blazevich, Greg Haff, James J. Tufano, Robert Newton, Keijo Häkkinen

Research outputs 2014 to 2021

As training experience increases it becomes more challenging to induce further neuromuscular adaptation. Consequently, strength trainers seek alternative training methods in order to further increase strength and muscle mass. One method is to utilize accentuated eccentric loading, which applies a greater external load during the eccentric phase of the lift as compared to the concentric phase. Based upon this practice, the purpose of this study was to determine the effects of 10 weeks of accentuated eccentric loading vs. traditional isoinertial resistance training in strength-trained men. Young (22 ± 3 years, 177 ± 6 cm, 76 ± 10 kg, n = …

A Meta-Analytic Review Of The Efficacy Of Physical Exercise Interventions On Cognition In Individuals With Autism Spectrum Disorder And Adhd, Wei Z. Tan, Julie Ann Pooley, Craig P. Speelman

Research outputs 2014 to 2021

This review evaluates the efficacy of using physical exercise interventions on improving cognitive functions in individuals with autism spectrum disorder (ASD) and/or attention deficit hyperactivity disorder (ADHD). This review includes a meta-analysis based on a random-effects model of data reported in 22 studies with 579 participants aged 3–25 year old. The results revealed an overall small to medium effect of exercise on cognition, supporting the efficacy of exercise interventions in enhancing certain aspects of cognitive performance in individuals with ASD and/or ADHD. Specifically, similar to the general population literature, the cognitive benefits of exercise are not consistent across all aspects …

Musculoskeletal Asymmetry In Football Athletes: A Product Of Limb Function Over Time, Nicolas H. Hart, Sophia Nimphius, Jason Weber, Tania Spiteri, Timo Rantalainen, Michael Dobbin, Robert Newton

Research outputs 2014 to 2021

Purpose

Asymmetrical loading patterns are commonplace in football sports. Our aim was to examine the influence of training age and limb function on lower-body musculoskeletal morphology.

Methods

Fifty-five elite football athletes were stratified into less experienced ( ≤ 3 yr; n = 27) and more experienced ( > 3 yr; n = 28) groups by training age. All athletes underwent whole-body dual-energy x-ray absorptiometry scans and lower-body peripheral quantitative computed tomography tibial scans on the kicking and support limbs.

Results

Significant interactions between training age and limb function were evident across all skeletal parameters (F16, 91 = 0.182, P = 0.031, …

Accuracy In Measurement Of Elevation Gain In Road Cycling, Paolo Mensaspa, Eric Haakonssen, Avish Sharma, Brad Clark

Research outputs 2014 to 2021

Purpose

Accurate measures of elevation gain are important for monitoring energy expenditure and physical load. The aim of this study was to determine the accuracy of barometric devices used for measuring elevation gain.

Methods

Observational validation study. Twenty-eight barometric altimeter devices (SRM and Garmin) were used to measure total elevation gain during cycling over three different climbs (length range: 3.2-18.4 km), giving a total of 216 climbs. An online mapping tool (http://www.freemaptools.com/elevation-finder.htm) was used to calculate the criterion measure of total elevation gain. Data were categorised into two weather conditions: dry and wet.

Results

The standard errors of the estimate …

The Effects Of Either A Mirror, Internal Or External Focus Instructions On Single And Multi-Joint Tasks, Israel Halperin, Steven Hughes, Derek Panchuk, Chris Abbiss, Dale W. Chapman

Research outputs 2014 to 2021

Training in front of mirrors is common, yet little is known about how the use of mirrors effects muscle force production. Accordingly, we investigated how performing in front of a mirror influences performance in single and multi-joint tasks, and compared the mirror condition to the established performance effects of internal focus (IF) and external focus (EF) instructions in a two part experiment. In the single-joint experiment 28 resistance-trained participants (14 males and 14 females) completed two elbow flexion maximal voluntary isometric contractions under four conditions: mirror, IF, EF and neutral instructions. During these trials, surface EMG activity of the biceps …

Exercise Improves Physical Function And Mental Health Of Brain Cancer Survivors: Two Exploratory Case Studies, Gregory T. Levin, Kenneth M. Greenwood, Favil Singh, Daphne Tsoi, Robert U. Newton

Research outputs 2014 to 2021

Background

Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases.

Methods

Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions …

Discriminating Talent Identified Junior Australian Footballers Using A Fundamental Gross Athletic Movement Assessment, Carle T. Woods, Henry Banyard, Ian Mckeown, Job Fransen, Sam J. Robertson

Research outputs 2014 to 2021

Talent identification (TID) is a pertinent component of the sports sciences, affording practitioners the opportunity to target developmental interventions to a select few; optimising financial investments. However, TID is multi-componential, requiring the recognition of immediate and prospective performance. The measurement of athletic movement skill may afford practitioners insight into the latter component given its augmented relationship with functional sport specific qualities. It is currently unknown whether athletic movement skill is a discriminant quality in junior Australian football (AF). This study aimed to discriminate talent identified junior AF players from their non-talent identified counterparts using a fundamental gross athletic movement assessment. …
