Effects of lower limb muscle strengthening on interface pressure in older adults undergoing inelastic compression: Randomized controlled clinical trial.
Study Goal
The researchers aimed to analyze the effects of lower limb muscle strengthening on interface pressure, static stiffness index, dynamic stiffness index, and walking pressure amplitude in older adults undergoing inelastic compression therapy.
Results Summary
The resistance training group showed increased lower limb muscle strength, which was accompanied by increased interface pressure during foot dorsiflexion and plantar flexion maneuvers, both while standing and during gait.
Population
Forty-three healthy older adults of both sexes (Age: 66.2 ± 4.4 years).

OBJECTIVE: To analyze the effects of lower limb muscle strengthening on interface pressure (IP), static stiffness index (SSI), dynamic stiffness index (DSI), and walking pressure amplitude (WPA) in older adults undergoing inelastic compression therapy. METHOD: Forty-three healthy older adults of both sexes (Age: 66.2 ± 4.4 years) met the eligibility criteria and completed all stages of the study (Resistance Training - RT: N = 20; Control - CONT: N = 23). Body composition, strength and functional mobility of lower limbs, IP, SSI, DSI, and WPA were evaluated before and after intervention. RESULTS: The two-way ANOVA with repeated measures demonstrated a significant time-group interaction effect on muscular strength for 1-RM [F (1, 41) = 21.091; CONCLUSIONS: In RT group, the increase in lower limb muscle strength was accompanied by an increase in IP in foot dorsiflexion and plantar flexion maneuvers, both in the standing position (DSI) and during gait (WPA).
