Most Effective Knee Joint Angle Pair for Isometric Exercise

This study investigated the effects of isometric exercises applied to the quadriceps and hamstring muscles at different knee joint angles on balance, joint position sense, and functional performance in healthy individuals. Thirty participants aged 18-26 years were randomized into four groups and performed an eight-week training program, three times per week. Outcome measures included the Y Balance Test, digital goniometer assessments for joint position sense, and functional performance tests (stair climb and 30-second sit-to-stand). The results aim to identify which knee joint angles are most effective for improving neuromuscular function and may guide future rehabilitation and training protocols.

Foot and Ankle Strengthening Program to Improve Physical Function in Menopausal Women

This randomized controlled trial will evaluate the effects of a 12-week foot and ankle strengthening program on physical function and health-related quality of life in menopausal women. Menopause is associated with hormonal changes that may negatively affect muscle strength, balance, and functional capacity, potentially leading to reduced mobility and increased risk of falls. Although exercise interventions have demonstrated benefits in this population, most programs focus on global lower-limb training and rarely target the foot and ankle complex, which plays a key role in postural stability and gait propulsion. Approximately 60 menopausal women aged 45-65 years will be randomly assigned to either an intervention group performing a structured foot and ankle strengthening program or a control group maintaining their usual physical activity. The intervention will last 12 weeks and will include one supervised weekly session and four home-based sessions. The primary outcome will be ankle plantarflexion isometric strength measured by hand-held dynamometry. Secondary outcomes will include ankle strength in other directions, intrinsic foot muscle function, gait speed, spatiotemporal gait parameters, balance, foot-related functional status, and health-related quality of life.
