Short-term Circuit Training on Muscle Mass and Quality of Life in Sedentary Postmenopausal Women

The purpose of this graduate student research study is to provide healthcare professionals with evidence of the potential of circuit strength training in improving the physical and psychosocial well-being of postmenopausal women.

Inclusion Criteria: * Females aged between 50 and 75 years. * Self-reported postmenopausal status (i.e., cessation of menstruation for a minimum of 12 months). * Physically capable of participating in an exercise intervention. * No engagement in structured resistance or aerobic training programs in the six months preceding the study. Exclusion Criteria: * Classification as moderate and highly active on the International Physical Activity Questionnaire (IPAQ) (600-3000 MET-minutes/week for "moderate" and higher than 3000 MET-minutes/week for "high" score) * Diagnosis of any health condition that constitutes a contraindication to physical exercise (e.g., significant cardiovascular disease, orthopedic or neuromuscular restrictions impacting exercise performance or safety). * Regular use of medication with the potential to affect study outcomes (e.g., corticosteroids, immunosuppressants).
