The effect of a postural exercise program on muscle power in Italian high school students.
Saverio Sabina, Maria Rosaria Tumolo, Pierpaolo Mincarone and 9 others
PMID 33132520WHAT IT FOUND
Students' vertical jump height increased by 2.1 cm on average after eight weeks of postural exercises.
However, with no control group, it is impossible to know if the exercises caused the gain or if students simply improved from normal growth and activity.
Key findings
01The final cohort consisted of thirty-four students; seven did not completed the required minimum number of workout sessions.
02Difference between Initial and Final CMJ [cm], mean ± SD 2.1 (3.5)*
03The lack of a control group and the use of the CMJ as a proxy for the evaluation of postural intervention were considered weaknesses in this study.

What it does not show
No control group was included, so it is impossible to determine if the improvement was due to the intervention or normal development/activity. The sample size was small (34 students). The Canali Postural Method was not applied in its full form; personalized postural evaluation was omitted due to time constraints. The primary outcome (jump height) is an indirect measure of postural control efficacy.
Declared interests
One author, Vincenzo Canali, is the owner of the company that holds the rights to the Canali Postural Method being tested. He contributed to the study design and exercise selection but did not participate in execution.
The easy way to misread this
Do not conclude that this postural exercise program improves muscle power. The study had no control group, so the 2.1 cm increase in jump height could be due to natural growth, maturation, or general physical activity rather than the specific exercises.
