Purpose: The main aim of the present study was to investigate the effects of a workplace exercise intervention on physical functioning. Dose of the exercise and other physical activity outside the intervention were controlled for. The other aims were to determine the physical strain of training and determine training force as a percentage of work time (OPA), leisure time (LTPA) and time spent on all activities (AT). Methods: The study was a cluster randomized controlled trial (CRT) with each department as the unit of randomization (n=36, n=19, n=15, n=25). The cross-over design consisted of one 15-week intervention period of resistance training (30% 1RM) and training guidance, and another period of the same length with no training or guidance. The subjects (n=90) were office workers [mean age 45.7 (SD 8.5) years]. Percentage body fat was measured using bioelectrical impedance, spinal .. View More»
