“…Retirement was the most examined life transition with 29 studies (27.1%). In general, retirement was associated with increases in leisure-time PA, (recreational) walking, and domestic activities [40,84,85,87,88,90,91,93,96,99,100,103,104,[106][107][108][109]132] and decreases in occupational PA, active transportation, and total PA [83,84,93,103,104,106,107].
