What does the study say about body composition?

Each card translates the reported statistics into plain language. The result changes with the selected sex and intellectual-disability category.

Study interpretation: these findings describe groups of adolescents and do not predict an individual change in body composition.
Step 3

Increase activity gradually

Practical progression based on the activity ranges used in the study.

Keep in mindActivity is only one factor; nutrition, hormones and sleep may also affect body composition.

The numerical target is a practical progression cue based on the study's activity ranges, not a therapeutic dose prescribed by the article.

Study snapshot

Key findings

Male · No IDPhysical activity was associated with skeletal muscle mass; reported R² = 0.038.
Male sampleParticipants in higher activity categories showed significant differences in muscle mass and skeletal muscle mass compared with some lower-activity categories.
Female · Moderate IDPhysical activity was associated with SMM (R² = 0.185) and BMI (R² = 0.303).
Female sampleWhen all girls were compared across the four activity categories, no statistically significant body-composition differences were found.
