Psycho-physical interactions in Parkinson's Disease: Protocol for a prospective observational cohort study.

Background: Individuals with Parkinson's Disease (PD) often experience not only physical symptoms but also a higher prevalence of psychological issues, including depression, anxiety, schizophrenia, and psychotic symptoms, compared to the general population. The relationship between these physical and psychological symptoms remains poorly understood, particularly in relation to commonly used measures of physical function and a wider variety of psychological symptoms. Investigating this link is essential for optimising patient care.

Cultural, Linguistic, and Geographical Diversity of Participants in Australian Physical Activity Research Studies: A Systematic Review.

Background: The Australian population is highly diverse in terms of cultural heritage, languages spoken, and geographical dispersion. Health outcomes are often worse among these culturally, linguistically, and geographically diverse populations, and this is reflected in rates of physical activity participation, with people from these groups often engaging in insufficient physical activity for health benefits. This research aimed to investigate if physical activity intervention studies conducted in Australia were (1) designed to recruit culturally, linguistically, and geographically diverse participants and (2) recruiting culturally, linguistically, and geographically diverse participants.

The relationship between physical function and psychological symptoms in Parkinson's disease: A systematic review and meta-regression analysis.

Aims: This systematic review and meta-regression aimed to examine available literature reporting measures of physical function, anxiety, and/or depression and whether any relationships exist between these measures in individuals with Parkinson's disease.

Methods: MEDLINE, CINAHL, AMED, and APA PsychInfo databases were systematically searched. Screening, quality assessment, and data extraction were completed alongside meta-regression analysis.

Examining the validity, reliability and feasibility of capturing children's physical literacy through games-based assessment in physical education.

Background: Observational tools can help refine practice design and guide the creation of effective learning environments. The intention of this study was to design and validate an observational instrument for assessing physical literacy that remains more faithful to the philosophically complex and holistic nature of the concept.

Methods: Framed by concepts of ecological dynamics, the emergent games-based assessment tool enables capture of children's interactions with their environment, providing insight on the manifestation of physical literacy within physical education games.

Acute aerobic exercise-conditioned serum reduces colon cancer cell proliferation in vitro through interleukin-6-induced regulation of DNA damage.

Epidemiological evidence shows that regular physical activity is associated with reduced risk of primary and recurrent colon cancer. However, the underlying mechanisms of action are poorly understood. We evaluated the effects of stimulating a human colon cancer cell line (LoVo) with human serum collected before and after an acute exercise bout vs nonexercise control serum on cancer cell proliferation.

The serological responses to acute exercise in humans reduce cancer cell growth in vitro: A systematic review and meta-analysis.

We systematically reviewed and meta-analyzed the effects of acute exercise-conditioned serum on cancer cell growth in vitro. Five literature databases were systematically searched for studies that measured cancer cell growth after exposure to human sera obtained before and immediately after an acute bout of exercise. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were pooled using a three-level random-effects model.

Validity of various portable devices to measure sit-to-stand velocity and power in older adults.

Background: Movement velocity and power in a single STS are related to functional performance in older adults. Identifying accessible tools that provide valid measures of STS velocity/power would allow practitioners to evaluate physical function in clinical settings where time, space and finances are limited.

Research Question: Does a linear position transducer (LPT), iPhone application (App), and inertial measurement unit (IMU) obtain valid measurements of velocity and power during a single STS compared with 3D motion capture?

Methods: Twenty-seven community-dwelling older adults aged ≥60 years completed a single STS test with mean velocity and power simultaneously measured with 3D motion capture, an LPT, IMU and App.

Three-curve rocker-soled shoes and gait adaptations to intermittent claudication pain: A randomised crossover trial.

Background: Intermittent claudication (IC) is a symptom of peripheral arterial disease where a cramp-like leg pain is exhibited during walking, which affects gait and limits walking distance. Specifically-designed rocker-soled shoes were purported to mechanically unload the calf musculature and increase walking distances until IC pain.

Research Questions: Do three-curve rocker-soled shoes increase walking distance and what are the biomechanical differences during pain-free walking and IC pain-induced walking, when compared with control shoes?

Methods: Following NHS ethical approval, 31 individuals with claudication (age 69 ± 10 years, stature 1.

Relationships Between Eccentric and Concentric Knee Strength Capacities and Maximal Linear Deceleration Ability in Male Academy Soccer Players.

Harper, DJ, Jordan, AR, and Kiely, J. Relationships between eccentric and concentric knee strength capacities and maximal linear deceleration ability in male academy soccer players. J Strength Cond Res 35(2): 465-472, 2021-The purpose of this study was to investigate the relationships between maximal linear deceleration ability, and knee flexor (KF) and knee extensor (KE) strength.

Sprint interval training on the vertical treadmill improves aerobic and anaerobic running performance.

The vertical treadmill (VertiRun) is an unresearched mode of exercise where users engage in a "running-like" action whilst body weight is supported by a recumbent bench and overhanging resistance cables are tethered to the user's ankles. The purpose of this study was to determine the effects of training on a VertiRun and any cross-training effect on running performance. Thirty active males (age, 22±4 years; stature, 1.

Unloading shoes for intermittent claudication: a randomised crossover trial.

Background: The purpose of this study was to assess the functional effects and acceptability of rocker-soled shoes that were designed to relatively "unload" the calf muscles during walking in people with calf claudication due to peripheral arterial disease.

Methods: In this randomised AB/BA crossover trial, participants completed two assessment visits up to two weeks apart. At each visit, participants completed walking tests whilst wearing the unloading shoes or visually-similar control shoes.

Kinematics and neuromuscular recruitment during vertical treadmill exercise.

The vertical treadmill (VertiRun) is an unresearched, partial weight-bearing exercise mode for lower limb rehabilitation. The user undertakes a "running-like" action whilst body weight is supported by a bench and the limb is drawn downwards against overhanging resistance cables on a vertically hung nonmotorised treadmill. This study sought to describe the kinematics and neuromuscular recruitment during VertiRun exercise in the supine, 40°, and 70° postures.

Computerized dynamic posturography in the objective assessment of balance in patients with intermittent claudication.

One-third of all elderly patients fall each year and impaired balance has been recognized as a specific risk factor. Intermittent claudication is common among the elderly population, affecting approximately 5% of the population over the age of 50. The aim of this proof-of-concept study was to assess the prevalence of impaired balance among elderly claudicants and to assess each patient's insight into their own risk of falling.

Kinematic adaptations to ischemic pain in claudicants during continuous walking.

Intermittent claudication has been associated with impaired gait and balance. The study aim was to compare gait adaptations over time between claudicants classified with good versus poor balance. Kinematic data were collected from 24 claudicants during continuous walking.
