    Moving Medicine

    http://movingmedicine.ac.uk/

    We are Moving Medicine, an initiative by the Faculty of Sport & Exercise Medicine UK in partnership with Public Health England and Sport England. We work with clinicians, hospitals and patients to spread the word about the remarkably positive effects that just a little bit of movement can have on the symptoms of many common diseases.

    We never just hear music. Our experience of it is saturated in cultural expectations, personal memory and the need to move

    Keeping active or becoming more active in middle and older age linked to longer life

    https://www.sciencedaily.com/release...0626200337.htm

    Keeping physically active or becoming more active during middle and older age is associated with a lower risk of death, regardless of past activity levels or existing health conditions, suggests a large study.

    How to Optimize Your Running Technique

    https://www.bettermovement.org/blog/...ning-technique

    There is a common theme to this research: the body has very good intuitive sense of how to run safely and efficiently. It learns through trial and error, and the best thing you can do to help it learn faster is to go through lots of trials and errors in high volume and sufficient variety.

    Does this mean we should ignore all the biomechanical advice about how to run? I think not.

    Does variability of footfall kinematics correlate with dynamic stability of the centre of mass during walking?

    https://journals.plos.org/plosone/ar...l.pone.0217460

    An efficient walking pattern is characterised by a variety of distinct gait domains, such as pace, rhythm, symmetry, variability and balance [1, 2]. With age, as well as in subjects with neuromotor deficits, all or some of these domains are perturbed, which ultimately results in an increased risk of falling [35]. While measures to quantify variability during walking are known to be sensitive in the discrimination of faller and non-faller subjects, their power to estimate fall risk on an individual basis prior to a first fall, remains unclear [3, 68]. It is generally assumed that the movement of the centre of mass (CoM) during walking is maintained (returned back to a steady-state after a perturbation) by effectively negotiating the placement of our feet, formally described as the base of support (BoS), and provides the primary means for stabilizing the system [912].

    Rapid Visuomotor Responses Reflect Value-Based Decisions

    http://www.jneurosci.org/content/39/20/3906.full

    Our results show that the size of rapid visuomotor responses to a sudden change in visual feedback about limb position depends upon the relative values of potential movement goals. Previous work showed that rapid feedback responses are flexibly regulated according to multiple components of the task, including timing (Franklin and Wolpert, 2008; Cluff and Scott, 2015) and spatial precision constraints (Gallivan et al., 2016), the presence of obstacles in the environment (Nashed et al., 2012, 2014), and the energetic or control costs associated with potential corrective responses (Nashed et al., 2012, 2014; Pruszynski et al., 2014). Rapid feedback responses can also reflect a control policy intermediate between those associated with competing goals when there is uncertainty about which goal will ultimately be specified (Gallivan et al., 2016). This illustrates that sensorimotor control policies are sufficiently flexible to take account of multiple potential goals simultaneously. However, this previous work that examined the flexibility of fast feedback responses manipulated physical characteristics of the task that are inherently coupled to the required motor outputs. Our current results show that feedback control is sensitive to decision variables, such as prospective reward, under otherwise identical task conditions. This suggests that feedback control policies that govern state-dependent transformations of sensory feedback to motor commands can be tailored to implement value-based choice.
    A rational agent seeking to maximize cumulative rewards in the long run should make choices according to the relative value of available options. However, humans and other animals often behave according to risk-modulated value functions; they make choices that lead to lower overall gains by favoring larger, less certain rewards when risk seeking, or more certain but smaller rewards when risk averse. Both risk-seeking and risk-averse behavior have been exhibited in motor decision tasks, depending on factors such as the probability of successful outcomes (Trommershäuser et al., 2008; Wu et al., 2009; Nagengast et al., 2010, 2011b; McDougle et al., 2016). Interestingly, the valence of risk modulation in motor tasks is often mirror opposite to that observed for economic decisions (Wu et al., 2009; McDougle et al., 2016). Our current results suggest that rapid feedback responses are tuned to a risk-averse value function. An interesting future question might be to determine whether an individual's risk sensitivity in visuomotor response regulation correlates with their risk sensitivity in cognitive decision-making.

    Don’t just do it, think about it too: how Gilbert Ryle’s philosophy of mind can help athletes teach themselves to improve

    https://aeon.co/essays/dont-just-do-...h-gilbert-ryle

    For Ryle, thinking is something that we do in our actions. We can get a grip on this idea by considering one of Ryle’s descriptions of skilful action:
    A mountaineer walking over ice-covered rocks in a high wind in the dark does not move his limbs by blind habit; he thinks what he is doing, he is ready for emergencies, he economises in effort, he makes tests and experiments; in short he walks with some degree of skill and judgment. If he makes a mistake, he is inclined not to repeat it, and if he finds a new trick effective he is inclined to continue to use it and to improve on it. He is concomitantly walking and teaching himself how to walk in conditions of this sort.
