Objective: To determine the efficacy of an evidence-based computer-assisted program vs. standard care to improve maximum cardiorespiratory fitness (cf) and quality of life. Design: RCT and systematic search of the literature and evaluation of the evidence of our structured and guided program of training and nutrition (bestbenefit = bbf). Setting: 54 participants, 31 women and 23 men. Average age was at 43.4 years, the BMI at 25.3 kg/m2; feel "healthy"; no sports for at least 2 years. Interventions: Participants were randomised to a control group (cg) with standard fitness intervention or the bbf group. The bbf program makes use of all proven measures to promote compliance and is tailored to the VO2max, the anaerobic threshold, the personal preference of the probands. Main outcome measure: Compliance, cf and increase in quality of life. Results: The bbf program achieved a significantly higher level of compliance (mean exercise sessions per week: 2 for the bbf vs. 1.4 for the cg; p = 0.002) and a highly significant increase in cf (16.6 % vs. 8.7 %; p < 0.003). In the overweight (BMI > 25; n = 23), a significant increase in the VO2max could be achieved in the bbf group over the cg (19.8 % vs. 4.5 %; p = 0.013). Probands, which were able to accomplish a reduction in weight (> 1kg), have a significantly higher increase in fitness than probands, who could not reduce their weight (12.47 % vs. 22.35 %, p = 0.013). There was no significant difference in improvement of CVD risk, depression, fatigue, MHSS and PHSS. The before/after comparison of the collective was significantly better for these factors. This indicates that exercise has a positive impact on these factors, independent of intensity and the absolute increase in VO2max. Conclusion: This enhancement of fitness of more than 20 %, achievable in the guided setting, may be of interest for risk groups (CVD, depression, cancer) with a substantially decreased cf. The effect on health-relevant end points should be studied in the longer term.
