Spanish scientists have experimentally demonstrated how wearing "unstable" sneakers instead of regular shoes affects the work of the muscles of the back and abs. Using electromyography, the authors monitored the muscle activity of volunteers walking on a treadmill. It turned out that "unstable" shoes not only use the leg muscles, but also increase the load on the core muscles, and also increase the mobility of the spine. The new study is published in the European Journal on Physical Medicine and Rehabilitation after Pathological Events.
To participate in the experiment, scientists invited 48 volunteers. They were provided with two pairs of shoes: the "unstable" Skechers Shape Ups with arched sole and the "regular" Classic Reebok flat sneakers. After the participant had become accustomed to wearing “unstable” shoes for 20 minutes, he did three control “runs” on the treadmill. At this time, scientists were taking myographic readings: electrical potentials arising in the muscles of the back and the press.
It turned out that in all phases of movement (leg swing, support, full step cycle), the muscles of the back and the press when wearing "unstable" shoes were involved more strongly, on average, one and a half times. In addition, the average range of back mobility has also increased by 3 degrees.
The authors attribute both results to the fact that “unstable” footwear, in accordance with its name, greatly complicates maintaining balance. In addition to the leg muscles, the back and abs are also involved in this task, which keep the body in an upright position.
The creation of "unstable" shoes was originally motivated by research that traditional flat-soled shoes make the leg muscles weaker by providing additional support and stability than walking barefoot.
Previous research has demonstrated the potential for “unstable” shoes in rehabilitation courses. They were recommended for people who needed to restore the motor function of the leg muscles. The authors of the new work come to the conclusion that such shoes can and should be used not only for the development of leg muscles, but also for the body.
