Training-induced Muscle Strength and Its Role in Interface Pressure in Inelastic Compression

Training-induced Muscle Strength Increase and Its Role in Interface Pressure in Inelastic Compression: A Randomized Clinical Trial

The present study will answer the following question: what are the effects of strength gain and muscle hypertrophy on interface pressure, static stiffness index, and working pressure amplitude in the elderly using inelastic compression?

This phase I two-armed randomized clinical trial including participants above 60 years of age who do not present any musculoskeletal limitations preventing their participation in resistance exercise programs will be conducted at the Ativas Gym, Xanxere/SC, Brazil. Participants will perform exercises during the strength-training protocol intervention, while individuals in the control group will not be offered the exercise program in the three months before data collection and during the entire period corresponding to the 12-week intervention. In addition, we will monitor their eating and physical activity habits throughout the data collection period. The study was designed in accordance with the CONSORT statement.

Inclusion Criteria:

• Participants above 60 years of age who do not present any musculoskeletal limitations preventing their participation in strengthening exercise programs.

Exclusion Criteria:

• Participants who present chronic venous insufficiency (CEAP C3-6) evaluated through Doppler ultrasonography, severe congestive heart failure (functional class III and IV - NYHA), and Ankle/Brachial Index (ABI) < 0.8. We will also exclude elderly individuals who are unable to perform the required exercises due to physical limitations and those bedridden or wheelchair-bound.
