Muscle tightness

Researchers test whether a six-week program that strengthens the posterior oblique sling, a network of back and hip muscles, can improve walking speed, stride length, and cadence in young adults with muscle tightness. Participants aged 18 to 30 with tightness in the latissimus do…

This study tested whether doing active hamstring stretches for 10 minutes a day, five days a week for six weeks, could reduce muscle tension in the lower back of office workers. Fifty-two desk workers who sat at least 5 hours daily participated. Researchers measured muscle activi…

This study looked at whether dynamic stretching or foam rolling works better for improving hamstring flexibility and muscle oxygen levels. Thirty-nine healthy adults with tight hamstrings did one session of either stretching or foam rolling. Researchers measured flexibility and m…

This completed study tested two techniques—tissue flossing and PNF stretching—to see which relieves hamstring tightness faster in young women. Sixty participants aged 18-25 with tight hamstrings received one technique, then the other a week later. Researchers measured flexibility…

This study looked at how dry needling changes the quadriceps muscle in 46 healthy adults. Researchers used ultrasound to measure muscle thickness and a device to test strength before and after the treatment. The goal was to understand the mechanical effects of dry needling on mus…
