2. Saying "you look efficient" makes people run more efficiently? The authors go to great lengths in the paper to put this result in the larger context of research showing that "motor performance and learning can be improved by providing individuals with 'positive' information about their performance or expected performance" Conversely negative feedback often makes people do worseIt's easier to see how negative feedback can make you worse: "Information indicating that one’s performance is less-than-perfect or even uncertainty about how one is performing (relative to others) due to lack of information presumably activates self-regulatory processes in attempts to manage thoughts and affective responses" In other words you start to overthink things which gets in the way of smooth motor functioning But to some extent these "self-regulatory processes" are always present so the benefit of positive feedback may be that it allows you turn those processes down a bit In the context of running (and other physical tasks) the result may be greater motor efficiency: "Changes in energy expenditure are presumably a function of increased movement efficiency associated with greater movement stability minimized co-contractions and generally more economical muscle activation patterns"So what does this tell us Well it's yet another argument [5] in favor of coaching through positive rather than negative reinforcement And it also may have some bearing on the hotly contested debates about running form and running efficiency There has long been a school of thought that through repeated training your body naturally "finds" its most efficient movement pattern On the flip side more recently many people argue that running form can and should be tweaked to become more efficient I think there's some truth on both sides of the debate (while I am skeptical of many popular approaches to "improve" running form I'm not a hardliner who believes that it's impossible to get more efficient)What this study reminds us is that there's a cost to consciously focusing on running form You're expending not just extra mental energy but also extra physical energy when you start worrying about your efficiency The result may still be worthwhile if you stick with it long enough that the new form becomes second-nature -- but there's something to be said for just clearing your mind of doubts and running***Read the Sweat Science book [6] and follow the latest posts via Twitter [7] Facebook [8] or RSS [9] published in the Journal of Sports Sciences [4],95 air max shoes, Recreational/Fun Walk/Run
