a scientific approach (year 2)

Dr. Jacopo A. Vitale Researcher IRCCS Galeazzi Orthopedic Institute e-mail: jacopo.vitale@grupposandonato.it

• Summary of year 1 “New” team, numbers and dissemination activities.

• Activities of year 2: participation of beneficiary students in grassroots sports.

• Did we reach the final goal of 30%? The Kaplan-Meier survival curve.

• Data collection: results of physical tests and questionnaires.

during physical education hours!

Other sports (no Oblomov)

Oblomov workshops again!

ObLoMoV workshops

Grassroot sport participation

1. Anthropometric measures

2. Physical tests

3. Questionnaires

4. HR monitoring / intensity

1. Questionnaires

2. Grassroot sport participation

Preliminary data PRE vs POST (1 and 2): statistical approach

• The normal distribution of each variable was checked with the Shapiro–Wilk test and graphical methods.

• Paired t-test were used to compare data between PRE and POST 1 evaluations.

• One-way ANOVA were used to compare data between PRE vs POST 1 vs POST 2 evaluations.

• When normal distribution was not checked, non parametric statistical tests (Wilcoxon for paired or

Mann-Whitney) were used for all comparisons. Friedman’s test was used for 3-groups comparisons.

• (Correlations [Pearson’s r or Spearman’s rho] among variables (BMI vs performance; performance vs

habits; etc…) could be performed too).

• Effect size (Cohen’s D) and magnitude base inference (MBI) should be performed *

• A p-value ≤0.05 was considered statistically significant.

TAKE HOME MESSAGEs

1. 44.6% of the beneficiary students were involved in grassoroot sports in 2018- 2019

2. School teachers implemented the Oblomov method in their 2018-2019 school programs

3. + 34 new students, +1 teacher, +2 HEPA trainers were involved in the project in 2018-2019

4. Beneficiary students improved their physical fitness and activity levels.
