„Die Spiele der Jugend sind kein müßiger Zeitvertreib, sondern sie gehören zu den wichtigsten
Erziehungsmitteln, bei deren Auswahl und Wechsel der Zweck der harmonischen Ausbildung des
Körpers und Geistes im Vordergrund stehen sollte.“ Wilhelm Max Wundt (1832 - 1920).

Definition Physical Therapists
• «Physical therapists (PTs) are highly-educated,
licensed health care professionals who can help
patients reduce pain and improve or restore mobility

• Recommendation 7. Strength training may be
included in addition to balance training
“…, the inclusion of strength training does not seem to be
crucial for an effect of exercise on falls,….”

Proposed biologic mechanisms contributing to dynapenia (the age-associated loss of strength).
It shows the influence of multiple factors that may lead to muscle weakness in the elderly.

• Bilateral reduction in prefrontal brain activity; preferred &
fast locomotion (larger effects in video game)
• Increase in hemispheric PFC activity asymmetry
• Increased differentiation in PFC activity related to
walking speed
• Adaptations resemble more trained or young adult-like
brain functions
• Prefrontal adaptations correlate with improved
performance in executive functions and processing
speed
