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; p ≤ 0.001], IP in the orthostatic position [F (1, 41) = 5.124; p ≤ 0.05], minimum WPA [F (1, 41) = 10.999; p ≤ 0.05], maximum WPA [F (1, 41) = 8.315; p ≤ 0.05], DSI minimum (F (1, 41) = 4.608; p ≤ 0.05), DSI maximum (F (1, 41) = 8.926; p ≤ 0.05), and on the delta DSI (F (1, 41) = 7.891; p ≤ 0.05).
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).
