Influences of trunk stability on exercise performance of closed kinetic chain of upper and lower limbs.
Obu Horii, Makoto Sasaki
PMID 37131349WHAT IT FOUND
Performing rhythmic stabilization on the trunk immediately before testing improved upper and lower limb performance in healthy male students.
Push-up and step-up times shortened significantly. This suggests trunk stability influences limb motor tasks, but the study did not test long-term training effects.
Key findings
01Trunk stability scores were significantly higher after performing rhythmic stabilization compared to the non-stabilization condition.
02Time required to complete push-ups and lateral step-ups was significantly shorter after rhythmic stabilization.
03Changes in left trunk stability correlated significantly with changes in limb performance, but right trunk stability did not.

What it does not show
The study included only healthy male university students, so results may not apply to females, older adults, or clinical populations. The study tested an immediate effect of one technique, not the effect of a training program over time. The sample size was small (27 participants). The correlation between trunk stability and limb performance was only significant for the left side, which the authors could not fully explain.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not interpret this as evidence that a trunk stability training program will improve patient function or athletic performance. The study only measured the immediate effect of one manual technique on healthy young men, not the cumulative effect of training.
