Walking is regulated and coordinated through complex control mechanisms within the human sensory motor system, allowing individuals to adapt to both internal and external challenges and perturbations (Full et al., 2002). During this regulation to achieve stable walking, natural fluctuations (i.e. movement variability) are present between strides in both the […]
For decades, there has been a consensus amongst scientists and practitioners that one of the ways people become stronger after resistance training is that their muscles become bigger. This increase in muscle size is termed muscle hypertrophy. Over the past 3 years, however, Jeremy Loenneke’s research group at the University […]
Previous studies have shown that healthy individuals, when asked to locate the position of the tips and knuckles of each finger on their hand when it could not be seen, consistently misjudge the size and shape of their hand (Longo & Haggard, 2010). They overestimate the width of their hand […]
The one repetition maximum (1RM) is a test of muscle strength. It is defined as the maximal amount of weight an individual can lift once, but not twice, when using the correct technique. Common 1RM tests include the bench press, chest press machine, biceps curl, lat pulldown, back squat, leg […]
Regular physical activity is important for our health and well-being. Recent evidence suggests that independent of being physically active, limiting the duration of sedentary behavior, such as sitting or lying down, is important to reduce the risk for cardiovascular disease, diabetes, cancer and all-cause mortality (Biswas et al. 2015). Advances […]
Scientific discoveries must be reported accurately. If not, the general public will lose trust and question why their tax dollars are being wasted. Unfortunately, the quality of research reports in the biomedical sciences is generally poor. Basic statistical reporting is inadequate, and spin – the distorted, self-serving interpretation of results […]
Over the past 4.5 years, researchers from all over the world have written non-technical summaries on their research for the Motor Impairment Blog. Consequently, the Blog contains a rich archive of information on topics such as muscle strength and weakness, falls and balance, sensation, pain, motor control, and research methods. […]
It’s 6AM. Last night, you missed dinner and you’ve woken up early because your body is ready for a feed. You stumble from your bedroom into the kitchen. You open the fridge and search for your favourite jar of jam. It’s nowhere to be found. Your partner finished it (without […]
Little is known about the small intrinsic foot muscles and their function during walking and running. In this video, Prof Andrew Creswell of the University of Queensland talks about the results of his research in which he has utilized imaging ultrasound and intramuscular electromyography to study the role of intrinsic […]
Studies on motor impairments sometimes involve electrophysiological measures to assess the effects of therapeutic interventions. For example, to determine the effect of an exercise program on brain function/excitability, a researcher might measure muscle responses elicited by non-invasive, magnetic stimulation of the brain (transcranial magnetic stimulation). When researchers plan their studies […]
