Background: One of the pathological hallmarks distinguishing Alzheimer's disease from other dementias is the accumulation of amyloid beta (A ). Higher physical activity is associated with decreased dementia risk, and one potential path could be through A levels modulation. We aimed to explore the relationship between physical activity and A in middle-aged and older adults. Methods: A systematic search of PubMed, Web of Science, PsycINFO, Cochrane Central Register of Controlled Trials, and SPORTDiscus was performed from inception to April 28, 2022. Studies were eligible if they included physical activity and A data in adults aged 45 years or older. Multi-level …


Effects Of Exercise Training On Muscle Quality In Older Individuals: A Systematic Scoping Review With Meta-Analyses, Tibor Hortobágyi, Tomas Vetrovsky, Jennifer S. Brach, Martijn Van Haren, Krystof Volesky, Regis Radaelli, Pedro Lopez, Urs Granacher Dec 2023

Effects Of Exercise Training On Muscle Quality In Older Individuals: A Systematic Scoping Review With Meta-Analyses, Tibor Hortobágyi, Tomas Vetrovsky, Jennifer S. Brach, Martijn Van Haren, Krystof Volesky, Regis Radaelli, Pedro Lopez, Urs Granacher

Research outputs 2022 to 2026

Background: The quantity and quality of skeletal muscle are important determinants of daily function and metabolic health. Various forms of physical exercise can improve muscle function, but this effect can be inconsistent and has not been systematically examined across the health-neurological disease continuum. The purpose of this systematic scoping review with meta-analyses was to determine the effects and potential moderators of exercise training on morphological and neuromuscular muscle quality (MMQ, NMQ) in healthy older individuals. In addition and in the form of a scoping review, we examined the effects of exercise training on NMQ and MMQ in individuals with neurological …


The Constituent Year Effect: Relative Age Disparities In Australian Masters Track And Field Athletic Participation, Nikola Medic, Jasmine Lares, Bradley W. Young Jan 2018

The Constituent Year Effect: Relative Age Disparities In Australian Masters Track And Field Athletic Participation, Nikola Medic, Jasmine Lares, Bradley W. Young

Research outputs 2014 to 2021

The constituent year effect, a source of relative age disparities, in masters sport has been demonstrated mainly amongst North American samples. Thus, the purpose of this study was to examine whether a participation-related constituent year effect exists among athletes (n = 6492) competing in Australian Masters Athletics competitions between 2000 and 2014. The results indicated that a participation-related constituent year effect was observed as the likelihood of participating was significantly higher for masters athletes in their first and second constituent year of any five-year age category (p < 0.0001) and was lower when they were in the fourth or fifth constituent year. The results also indicated this effect is influenced by gender and age. Specifically, the effect was significant for both male (p < 0.0001) and female (p < 0.001) masters athletes; as well during the third, sixth, seventh, and eighth + decades of life (all ps < 0.001). These data demonstrate that despite masters sport being an avenue for promotion of participation and overall health, there is potential for improving how competitive organizational strategies are implemented given the recurring intermittent patterns of participation associated with five-year age brackets which are likely to compromise benefits.


Perceptions Of Five-Year Competitive Categories: Model Of How Relative Age Influences Competitiveness In Masters Sport, Nikola Medic, Bradley Young, J. Robert Grove Jan 2013

Perceptions Of Five-Year Competitive Categories: Model Of How Relative Age Influences Competitiveness In Masters Sport, Nikola Medic, Bradley Young, J. Robert Grove

Research outputs 2013

The purpose of this study was to examine the contrasting perceptions of masters swimmers related to the first and fifth constituent years of a 5-year age category. Swimmers aged between 35 and 93 years (154 male, 184 female) were surveyed at the 2008 FINA World Masters Championships. Exploratory factor analysis indicated the existence of the following five factors considered important for preparation, attendance, and success at masters competitions: awareness of advantages, expectancy, motivation, training, and physiological capacity. One sample ttests showed that masters swimmers are conscious of advantages that 5-year age categories afford to relatively-younger cohorts (i.e., those who are …
