Effects of Two Strength Exercise Programs on Upper Limb Functionality in Breast Cancer

Effects of Two Strength Exercise Programs on Upper Limb Functionality in Breast Cancer

The goal of this experimental study is to evaluate the effect of a therapeutic exercise program based on upper limb plyometric exercises in breast cancer patients and breast cancer survivors to determine changes in upper limb functionality.

The main question it aims to answer is: Does upper limb plyometric strength exercise improve upper limb dysfunctions in breast cancer patients and survivors? The researchers will compare the effects of plyometric exercise with the effects of strength training exercise to determine whether plyometric exercise improves shoulder dysfunctions in breast cancer patients and survivors.

Participants from the Pontevedra group will undergo the intervention using plyometric exercise (Experimental Group), while those from the Vigo group will perform strength training exercise (Control Group). They will complete two sessions per week for six weeks. Outcome variables related to upper limb functionality will be assessed at baseline and after the intervention.

Inclusion Criteria:

• Pathological diagnosis of breast cancer.
• Patients who have undergone a mastectomy, including unilateral, total breast, or breast-conserving surgery.
• Postoperative chemotherapy or radiotherapy as required.
• No other malignant tumors in the last 5 years.
• Absence of contraindications related to physiotherapy or physical exercise.
• Willingness to participate in the study and sign the informed consent form.

Exclusion Criteria:

• Metastasis to other organs and tissues (liver, kidney, lung, brain, etc.) that prevent participation in the exercise program.
• Underlying heart disease, cerebrovascular disease, or mental illness that impairs proper execution of the exercise program.
• Pre-existing shoulder pathology before surgery.
• Inability to understand the plyometric exercise program.
