Status Not yet recruiting

Clinical Trial Summary

The objective of this study is 1) to study the acute and chronic effect of resistance therapeutic physical exercise (RTPE) in the prevention of breast cancer-related lymphedema (BCRL) in breast cancer survivors at risk using variables related to the lymphatic response; 2) Study the possible relationship between changes in body composition at a local and regional level and volume changes produced by RTPE in patients at risk of suffering from BCRL.

Clinical Trial Description

Nowadays, research studies that confirm the safety and preventive effect of resistance or strength exercise in breast cancer-related lymphedema (BCRL) have been limited to the study of changes in variables related to the lymphatic response, such as bioimpedance spectroscopy , X-ray absorptiometry, perometry or water displacement after completion of a resistance exercise program (chronic effect).

To better understand the preventive effect of resistance exercise on the BCRL, in addition to studying the variables that are globally accepted and studied at a regional level such as the volume due to water displacement, variables that measure changes at a regional level related to body composition, such as such as echogenicity and ultrasound thickness, local tissue water and mechanical properties of tissues. Furthermore, this would allow us to detect possible changes in different body regions of the upper quadrant (upper extremity, but also breast or back), and not only taking global changes into account. On the other hand, the lymphatic response should be studied in the short term (acute effect), in the long term after an exercise program (chronic effect), as well as in the short term after the training period with possible adaptations to the lymphatic system that could explain the preventive effect.

Therefore, although there is a strong degree of scientific evidence to include therapeutic strength physical exercise as a preventive tool for LACM, the possible physiological mechanisms involved are unknown. The aim of the present project is to tudy the acute and chronic effect of resistance therapeutic physical exercise (RTPE) in the prevention of breast cancer-related lymphedema (BCRL) in breast cancer survivors at risk using regional but also local variables related to the lymphatic response, as well as to study between changes in these variables, body composition at a local and regional level and volume changes produced by RTPE in breast cancer survivors at risk of suffering from BCRL ;
