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 …

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 = …

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. …

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 …

The Effects Of Acute Dehydration Of 5% Body Mass On Performance And Physiology Of Mixed Martial Arts Athletes, Oliver Roland Barley

Theses: Doctorates and Masters

Mixed Martial Arts (MMA) athletes are weighed 24 h prior to competition. In order to compete in a lower weight class MMA athletes will often rapidly lose weight via dehydration. Despite the prevalence, there is currently no known published data examining the effects of acute dehydration on physiology and performance in mixed martial arts athletes. The present study aimed to examine: i) the effects of 5% acute dehydration on performance (vertical jump, medicine ball throw, grip strength and repeated sled push) and physiology (body weight, haematocrit, urine specific gravity, serum osmolality and urine osmolality) of MMA athletes. A total of …

Theses: Doctorates and Masters

The overall aim of this thesis was to increase strength and conditioning coaches, and sport scientists’ understanding of the lower-body muscle structures related to enhanced lower-body physical capacities, and how to best evoke desirable training-specific adaptations. To address this aim, three successive steps of research were evaluated: (1) analysis of the factors related to increased performance in competitive surfing, (2) relationships between lower-body muscle structures and factors associated with enhanced physical performance, and (3) comparison of the training-specific adaptations evoked from various training methods. Whilst this research specifically focused on competitive surfing athletes, these results may benefit the training practices …

The Efficacy Of Periodized Resistance Training In Older Adults, Jennifer Anne Conlon

Theses: Doctorates and Masters

Sarcopenia describes the slow and inevitable age-related loss of skeletal muscle mass and consequent function. Fortunately, a continually growing body of research highlights the robust adaptability of the aging neuromuscular system in response to resistance training (RT). Yet, despite an abundance of research studies describing the benefits of RT in the elderly, there is a large variation in the type of training programs employed. Therefore, within the extensive range of beneficial RT stimuli, it is vital to confirm what organizational structure of acute program variables is most effective (i.e. the appropriate dose). The process of organizing a training program considering …

Accuracy In The Badminton Short Serve: A Methodological And Kinematic Study, Shayne Marc Vial

Theses: Doctorates and Masters

In sports, accuracy is an essential component of actions such passing, shooting, and aiming. Executing a movement or action that requires a high degree of accuracy is a critical determinant of success in many individual and team sports. Each sport has different methods for evaluating accuracy, however an overarching goal is to determine whether an object hits its target, or assess the distance by which it misses. However, in some sports accuracy is not readily measureable because an object might not reach a target, i.e. the object is intercepted, or it collides with another object or a person, or an …

Muscle Damage And The Repeated Bout Effect In Male Bodybuilders Following Unaccustomed Resistance Exercise, Kennedy Blowfield
