Effects of high-intensity interval training and strength training on levels of testosterone and physical activity among women with polycystic ovary syndrome

Time to Load Up-Resistance Training Can Improve the Health of Women with Polycystic Ovary Syndrome (PCOS): A Scoping Review

BACKGROUND

Guidelines for the management of polycystic ovary syndrome (PCOS) focus on lifestyle changes, incorporating exercise. Whilst evidence suggests that aerobic exercise may be beneficial, less is known about the effectiveness of resistance training (RT), which may be more feasible for those that have low fitness levels and/or are unable to tolerate/participate in aerobic exercise.

OBJECTIVES

To identify the available evidence on RT in women with PCOS and to summarise findings in the context of a scoping review.

ELIGIBILITY CRITERIA

Studies utilising pre-post designs to assess the effectiveness of RT in PCOS; all outcomes were included.

SOURCES OF EVIDENCE

Four databases (PubMed, CENTRAL, CINAHL and SportDiscus) were searched and supplemented by hand searching of relevant papers/reference lists.

CHARTING METHODS

Extracted data were presented in tables and qualitatively synthesised.

RESULTS

Searches returned 42 papers; of those, 12 papers were included, relating to six studies/trials. Statistical changes were reported for multiple pertinent outcomes relating to metabolic (i.e., glycaemia and fat-free mass) and hormonal (i.e., testosterone and sex hormone-binding globulin) profiles.

CONCLUSIONS

There is a striking lack of studies in this field and, despite the reported statistical significance for many outcomes, the documented magnitude of changes are small and the quality of the evidence questionable. This highlights an unmet need for rigorously designed/reported and sufficiently powered trials.
