N1 - Funding Information:
This research was part of the SPRINT project ( www.projekt-sprint.de ). SPRINT is a joint project of the Technische Universität München and its corporate partners and was funded by the German Ministry for Research and Education (contract number FKZ 01FD0609). Study design, data collection, analysis and interpretation, writing of the report and submission of the results were not influenced by the funding source. This study was not financially supported by the BMW group; however, free access to facilities was enabled.

N2 - Objective: To evaluate the effect of structured vs. non-structured internet-delivered exercise recommendations on aerobic exercise capacity and cardiovascular risk profile in overweight sedentary employees. Methods: 140 employees of an automobile company (11% female, median age 48years (range 25-60), BMI 29.0kg/m2 (25.0-34.8)) were randomized in a 3:2 ratio to an intervention group receiving structured exercise schedules or a control group choosing workouts individually via an interactive website. The 12-week intervention took place in Munich, Germany, during summer 2008. Main outcome measure was performance at the lactate anaerobic threshold (PAT/kg) during ergometry. Results: 77 participants completed the study. The intervention group (n=50) improved significantly in PAT/kg ((mean (SD)) 1.68 (0.31) vs. 1.81 (0.33) W/kg; p=0.002), VO2peak (3.21 (0.63) vs. 3.35 (0.74) L/min; p=0.04), and waist circumference (100.5 (7.9) vs. 98.0 (7.8) cm; p=0.001). The control group (n=27) improved significantly in PAT/kg (1.59 (0.38) vs. 1.80 (0.49); p<0.001) and waist circumference (101.9 (8.7) vs. 98.3 (8.5) cm; p<0.001), but not in VO2peak. No significant between group differences in these outcome measures were noted. Conclusion: Structured, internet-delivered exercise recommendations are not superior to internet-delivered non-structured exercise recommendations in a workplace setting. Both lifestyle intervention strategies are, however, limited by high dropout rates.
