The Self Determination Theory (SDT)

Basically, a person gets more motivated if there is support given on relatedness, competence and autonomy. Therefore, a professional should establish a good and warm relationship with the elderly people and the youngsters. Overall, a positive, caring climate with mutual respect will build up a good relation. Secondly, the tasks should be not too complex or too basic. A level in which some effort is needed and motivational preferences are met, will give motivation for the future activities. Lastly, a professional should provide some different options. Providing elderly and youngsters with sufficient options will give them some space to find common ground and guarantee ownership. At the end, if a professional is capable of providing fulfilment of the three basic needs, long lasting motivation for physical activity is guaranteed.
