Title : Comparison of the handgrip strength of women in the using anthracycline during chemotherapy treatment with apparently healthy women
The number of studies involving patients with breast cancer and physical activity has increased in recent years. However, it is still unclear the effects of chemotherapy on handgrip strength measurements.To compare handgrip strength between women with breast cancer who are in the third to fourth cycle of chemotherapy treatment with apparently healthy women. Methods: This study is a cross-sectional study. The 37 women included in the study were divided into two groups: breast cancer treatment (TCM, n = 19) and apparently healthy (CNT, n = 18) and had 52.2 ± 13 , 11 years and 55.8 ± 8.37 years, respectively. Handgrip strength measurements were performed using a brand dynamometer using a digital dynamometer (model EH101, E.clear®), the tests consisted of three attempts with 3-5s of maximal voluntary contraction with 90 ° elbow with verbal stimulus, alternating right and left side and one minute rest interval between attempts, the highest measure was recorded. Data normality was verified by the Shapiro-Wilk test, and the data were compared between groups by Student's t test. For independent samples, the significance level adopted was p <0.05. Cohen's d-effect size was calculated from the difference in handgrip between groups to examine the magnitude of the effect of breast cancer treatment on the investigated variables.Handgrip strength measurements were not different between groups (p = 0.17), d = 0.45.The results obtained suggest that handgrip strength for women between the third and fourth cycle of chemotherapy treatment of breast cancer is not different from apparently healthy women.
