This review identified extensive heterogeneity between studies in exercise dose (FITT) [25].
Consequently, we could not examine the relationship between this measure of exercise dose and clinical outcomes.
Appendix 3 offers a detailed description of exercise dose by intervention within each selected study.
The findings from this study may help resolve the following unanswered questions, "For a given exercise dose does higher exercise intensity result in greater health benefits?" "For a given exercise intensity does higher exercise dose result in greater health benefits?".
Assessed study characteristics exhibited wide variability, particularly in their economic perspective, time horizon, setting, comparators and included costs, with significant heterogeneity in exercise dose across interventions.
Excluding the two modelling studies [16, 20] and the cohort study [21], the exercise dose of interventions was assessed using FITT (frequency, intensity, time and type).
In this review, such variability was particularly evident in study perspective, time horizon, setting, comparators, included costs, and in exercise dose (FITT) between interventions.
Additional data was extracted on study design, sample demographics, exercise dose, frequency and duration of follow-up, included costs, chronic multimorbidity and findings.
Conclusion: The addition of video/computer-based interactive exercises to usual rehabilitation is a safe and feasible way to increase exercise dose, but is not suitable for all.
The purpose of this review was to examine the relationship between exercise dose and reductions in weight gain during pregnancy in exercise interventions.
It could be argued that energy expenditure expressed as either MET-hours or kilocalories would have provided the most useful measure of exercise dose accounting for various combinations of intensity, frequency and duration of exercise sessions prescribed within an intervention.
