On 21 November 2016, eight PhD students from the University of Bremen, the Leibniz Institute for Prevention Research and Epidemiology - BIPS and the Hanze University of Applied Sciences Groningen met to exchange experiences within their research projects concerning the promotion of physical activity in older adults. Prof. Hans Hobbelen, member of the Scientific Advisory Board of AEQUIPA invited the young researchers from Bremen. Along with Prof. Hajo Zeeb, coordinator of the AEQUIPA PhD Programme, he initiated and supervised the workshop. The presentation of the research projects and the discussions showed, despite different research approaches, parallels in several areas. Therefore, the junior scientists desired further contact to intensify the exchange of experiences.
