Mind over muscle for lifting heavier and longer

Focusing one’s attention on aparticular musclewhen lifting promotes its activation — and by extension, its development.

But when the goal is muscle performance rather than growth alone, does this long-held notion still carry any weight?

Published inFrontiers in Sports and Active Living, new analysis by Professor David Neumann from Griffith University’s School of Applied Psychology suggests that to lift heavier, or longer, it is better to focus on moving the weight itself — not your muscles.

The way an athlete focuses their attention when lifting a weight has the potential to influence strength development during training and performance outcomes during competition.

In a systematic review, Professor Neumann investigated the effects of attentional focus strategies during weightlifting tasks.

Major databases (SportDISCUS, PsycINFO, Scopus) were searched using key terms relevant to attentional focus and weightlifting and reference lists of identified articles were also searched.

The review showed that researchers recruited experienced and novice weightlifters of both genders in their studies, although male experienced weightlifters are the most commonly studied demographic.

Think outside the bod

Proponents of the mind-muscle connection cite increased muscle activity, when focusing on specific muscles while lifting, as evidence of benefit.

That increased activity might translate to increased muscle hypertrophy, but put another way, Prof Neumann said mind-muscle connection makes you expend more effort to lift the same weight.

“The higher overall muscle activity with an internal ‘muscle focus’ is not specific to the muscles mentally isolated during lifting,” ProfessorNeumannsaid. “Rather, it seems to represent increased activity of non-target muscles, too.”

In contrast, studies have consistently shown that when weightlifters instead focus their attention on the external effects of their efforts, such as the movement of a barbell, lifts are done more economically and with less effort.

“It appears that this external focus allows automatic control processes to operate, removing the attentional demands and mechanical inefficiency of conscious muscular control.”

In any case, as the load increases — at 80% of maximum effort in one bench press study — the muscle activity advantage of a muscle focus, over an external focus, seems to disappear altogether.

The mind-muscle connection still holds

Professor Neumann recommends an external focus on moving a load to maximize athletes’ performance in training and competition — and as a potential complement to ‘dissociative’ focus strategies, like listening to music, for promoting exercise adherence in those who are less active.

This recommendation comes with many caveats. Whether anyparticular attentionalfocus strategy actually affects meaningful outcomes, like muscle fatigue or strength gains, remains to be determined.

Moreover, most relevant study samples are small — with 11-29 participants, prototypically young, Western, male and experienced in weightlifting.Larger, more demographically diverse studies,should probe the issue further.

“It would be worthwhile to examine whether transfer of these effects occurs to similar sporting tasks.

“For example, some sports like shot put and discus, require a short-term maximal muscular effort.

“We should also explore ways to maximize the beneficial effects of an external focus. Using VR for instance, completing a deadlift could be translated into an imperative like virtually lifting a heavy bar to free a trapped virtual person.”
