Efeito do treinamento resistido na saúde óssea de sobreviventes de câncer de mama: uma revisão narrativa

Abstract

The aim of this narrative review was to synthesize the current literature on the effect of resistance training on bone health in female breast cancer survivors. PubMed and SciELO were searched between May and November 2024. A combination of terms was used: (women with breast cancer OR breast cancer survivors OR survivors OR breast cancer OR survivors cancer AND strength training OR resistance training OR exercise training OR weight training OR exercise OR weight lifting OR weightlifting AND bone density OR bone health OR bone mineral density OR bone turnover). We included experimental studies that compared resistance training with a control group and reported dual-energy X-ray absorptiometry for bone mineral density evaluation. We found 28 studies, but only 4 were pre-selected according to the inclusion criteria. Most of the studies analyzed presented significant data regarding the increase in bone mineral density after interventions using resistance exercises ranging from 52 to 104 weeks. Despite the significant data, the effect sizes of these studies are small; therefore, other interventions such as the addition of aerobic training and/or calcium supplementation may provide clinically relevant results. Hence, more research is needed to determine the most effective resistance training intensity to improve bone health in female breast cancer survivors. By calculating the average of the characteristics in the four studies, we came to the following conclusions. The average age was 58.9 years. The participants in this study were, on average, overweight or obese. However, without the average height of the participants, it is not possible to calculate the average weight.
