© 2021, The Author(s). Background: Physical inactivity has been consistently linked to increased risk of cognitive decline; however, studies examining the impact of exercise interventions on cognition have produced inconsistent findings. Some observational studies suggest exercise intensity may be important for inducing cognitive improvements; however, this has yet to be thoroughly examined in older adult cohorts. The objective of the current study was to evaluate the effect of systematically manipulated high-intensity and moderate-intensity exercise interventions on cognition. Methods: This multi-arm pilot randomised clinical trial investigated the effects of 6 months of high-intensity exercise and moderate-intensity exercise, compared with an inactive …

Inconsistent Use Of Resistance Exercise Names In Research Articles: A Brief Note, James L. Nuzzo
Research outputs 2014 to 2021
Academic fields require standard nomenclature to communicate concepts effectively. Previous research has documented resistance training exercises are named inconsistently. This inconsistent use has been observed among fitness professionals and within resistance training textbooks. The purpose of the current note was to explore inconsistent use of resistance training exercise names in scientific articles. Keyword searches were performed in PubMed to identify articles that referred to 4 different resistance training exercises. The search was limited to titles and abstracts of articles published between 1960 and 2020. For exercise 1, "shoulder press," "overhead press," and "military press" were searched. For exercise 2, "arm …
Adaptations To Post-Exercise Cold Water Immersion: Friend, Foe, Or Futile?, Mohammed Ihsan, Chris R. Abbiss, Robert Allan
Adaptations To Post-Exercise Cold Water Immersion: Friend, Foe, Or Futile?, Mohammed Ihsan, Chris R. Abbiss, Robert Allan
Research outputs 2014 to 2021
In the last decade, cold water immersion (CWI) has emerged as one of the most popular post-exercise recovery strategies utilized amongst athletes during training and competition. Following earlier research on the effects of CWI on the recovery of exercise performance and associated mechanisms, the recent focus has been on how CWI might influence adaptations to exercise. This line of enquiry stems from classical work demonstrating improved endurance and mitochondrial development in rodents exposed to repeated cold exposures. Moreover, there was strong rationale that CWI might enhance adaptations to exercise, given the discovery, and central role of peroxisome proliferator-activated receptor gamma …

Research outputs 2014 to 2021
Physical exercise is increasingly recognized as a valuable treatment strategy in managing prostate cancer, not only enhancing supportive care but potentially influencing disease outcomes. However, there are limited studies investigating mechanisms of the tumor-suppressive effect of exercise. Recently, extracellular vesicles (EVs) have been recognized as a therapeutic target for cancer as tumor-derived EVs have the potential to promote metastatic capacity by transferring oncogenic proteins, integrins, and microRNAs to other cells and EVs are also involved in developing drug resistance. Skeletal muscle has been identified as an endocrine organ, releasing EVs into the circulation, and levels of EV-containing factors have been …

The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu
Senior Honors Theses
The hamstring muscle group, spanning the posterior aspect of the proximal lower limb, generates large amounts of contractile force during running. Researchers have examined this power generation within different phases of the stride cycle. Forces generated by the hamstrings hold implications for both running efficiency and the role of strengthening for injury prevention. The goal of this review is to examine the hamstring’s unique physiology as a bi-articular muscle, its role in running stride, various training philosophies, and the specific impact on running economy contributing to overall running performance. The summation of research presented shows that the hamstring muscle group …

Background:
Chronic obstructive pulmonary disease (COPD) is a disorder linked with a multitude of extra pulmonary manifestations (also known as treatable traits), including low bone mineral density (BMD). To date, no specific guidelines exist for the management of BMD in this population. Impact loading exercise has been identified as an intervention that improves or maintains BMD in other populations. However, the feasibility of and tolerance to impact loading exercise has not been tested in people with COPD. The aim of the proposed study will be to investigate the feasibility and tolerance of adding impact loading exercise to a standard pulmonary …

Enhancing Adaptions To Neuromuscular Electrical Stimulation Training Interventions, Anthony J. Blazevich, David F. Collins, Guillaume Y. Millet, Marco A. Vaz, Nicola A. Maffiuletti
Research outputs 2014 to 2021
Neuromuscular electrical stimulation (NMES) applied to skeletal muscles is an effective rehabilitation and exercise training modality. However, the relatively low muscle force and rapid muscle fatigue induced by NMES limit the stimulus provided to the neuromuscular system and subsequent adaptations. We hypothesize that adaptations to NMES will be enhanced by the use of specific stimulation protocols and adjuvant interventions.

Purpose
Radiation therapy is a commonly used treatment for prostate cancer; however, the side effects may negatively affect quality of life and cause patients to be less physically active. Although exercise has been shown to mitigate radiation therapy–related fatigue in men with prostate cancer during radiation therapy, other adverse effects of treatment such as physical deconditioning, urinary symptoms, or sexual dysfunction have not been systematically reviewed in this patient population. Thus, the purpose of this review was to investigate the effect of exercise on physical function and treatment-related side effects in men with prostate cancer undergoing radiation therapy.

Background: Weight-loss-induced fat loss improves cardiometabolic health in individuals with overweight and obesity; however, weight loss can also result in bone loss and increased fracture risk. Weight-loss-induced bone loss may be attenuated with exercise. Our aim was to compare changes in bone mineral density (BMD) in adults with overweight and obesity who undertook diet-induced weight loss alone or in combination with exercise. Methods: We included randomized controlled trials (RCTs) in adults with overweight or obesity (aged ≥ 18 years; body mass index ≥ 25 kg/m2) that prescribed diet-induced weight loss alone or in combination with supervised exercise, and measured any …

Abstract: Genetic variants in the angiotensin-converting enzyme (ACE) (rs4343), alpha-actinin-3 (ACTN3) (rs1815739), adrenoceptor-beta-1 (ADRB1) (rs1801253), and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PPARGC1A) (rs8192678) genes have previously been associated with elite athletic performance. This study assessed the influence of polymorphisms in these candidate genes towards endurance test performance in 46 players from a single Australian Football League (AFL) team. Each player provided saliva buccal swab samples for DNA analysis and genotyping and were required to perform two independent two-kilometre running time-trials, six weeks apart. Linear mixed models were created to account for repeated measures over time and to determine whether …
