Pronoun Position
Here the pronoun "usted" comes after the verb:
"Qué hace usted en su tiempo libre?"
Here it comes before:
"Usted practica muchos deportes?"
Does it's position matter in these cases?

You could also write: Usted, ¿practica muchos deportes?
Now, if I read ¿Usted practica muchos deportes? I could interpret that the emphasis is in usted, so I´m not really asking what sports but if you practise sports.
Sometimes, pronoun position may imply subtle differences.
In this position it doesn't matter.
You could use:
"Usted practica muchos deportes?" and "Practica usted muchos deportes?" both have the same meaning.
