Best Exercises for Plantar Flexion

Check out this answer from Consensus:

Incorporating a variety of plantar flexion exercises, including loaded inter-set stretches, resistance exercises, isometric holds, and static stretching, can effectively enhance muscle strength, flexibility, and overall foot and ankle function. These exercises are particularly beneficial for individuals recovering from injuries, those with chronic conditions like PAD and diabetes, and anyone looking to improve their lower leg strength and endurance.

Plantar flexion exercises are crucial for strengthening the muscles in the lower leg, particularly the calf muscles, and improving overall foot and ankle function. These exercises are beneficial for various populations, including athletes, patients with peripheral arterial disease, and individuals recovering from injuries. This article explores some of the best exercises for plantar flexion based on recent research findings.

Loaded Inter-Set Stretch

A study compared traditional resistance training (RT) with RT combined with a 20-second inter-set stretch during calf raise exercises. The results indicated that the inter-set stretch might enhance muscle thickness (MT) of the soleus muscle more effectively than traditional methods. Additionally, there was a modest improvement in plantar flexor strength with the inter-set stretch approach1.

Resistance Exercise During Bed Rest

Resistance exercise (REX) has been shown to prevent deconditioning of the plantar flexor muscles during periods of unloading, such as bed rest. A study found that performing concentric and eccentric plantar flexion exercises every other day maintained or improved muscle strength and power, effectively countering the negative effects of prolonged inactivity2.

Plantar Flexion Device for Peripheral Arterial Disease

For patients with peripheral arterial disease (PAD), a plantar flexion device exercise program can be beneficial. A study involving the “Step It” pedal device showed improvements in walking distance and claudication symptoms among participants who used the device in conjunction with standard care3. Another study confirmed that plantar flexion training significantly increased peak oxygen uptake and power output, enhancing overall walking performance and reducing leg pain5.

Isometric Calf Muscle Exercises

Isometric exercises, where the muscle length does not change during contraction, can provide immediate pain relief for individuals with Achilles tendinopathy. A study found that isometric plantar flexion exercises performed with the knee either extended or flexed resulted in a significant reduction in Achilles tendon pain during functional load tests4.

Static Stretch Training

Static stretching of the plantar flexor muscles can increase both eccentric and concentric torque, as well as ankle dorsiflexion range of motion. A study demonstrated that a six-week static stretching program led to significant improvements in muscle strength and flexibility, particularly in untrained individuals7.

Flexibility and Resistance Exercises for Diabetic Ulcers

For patients with diabetic foot ulcers, a combination of foot-ankle flexibility and resistance exercises can reduce the recurrence of ulcers and improve walking speed. A study showed that these exercises, performed three times a week, significantly decreased ulcer recurrence rates and enhanced diabetic neuropathy scores10.
