Why do legs suddenly feel weak when walking after doing frog jumps?

Generally, sudden leg weakness after frog jumps may be related to normal physiological responses, muscle strain, calcium deficiency, osteoarthritis, lumbar disc herniation, and other factors. Patients are advised to seek symptomatic treatment as directed by a physician. Specific analyses are as follows:

1. Normal Phenomenon

If an individual has long-term lack of exercise, frog jumps may easily cause excessive fatigue of muscles and ligaments, or the intensity of the exercise may be too high, leading to excessive lactic acid production in the muscles. This typically results in the aforementioned symptoms. Usually, no specific treatment is required; adequate rest or leg massage can help alleviate the discomfort.

2. Muscle Strain

If proper warm-up exercises are not performed before frog jumps, or if the movements are too intense, leg muscle strains may occur, causing soreness and weakness in the legs. Local ice application or massage may help. Alternatively, medications such as ibuprofen sustained-release capsules or flurbiprofen gel patches may be used under medical guidance.

3. Calcium Deficiency

If the patient suffers from calcium deficiency, abnormal muscle contractions in the legs may occur during frog jumps, resulting in leg weakness. This may also be accompanied by symptoms such as leg cramps and pain. It is recommended that patients take calcium supplements such as calcium lactate granules or oyster calcium carbonate granules under a doctor's supervision.

4. Osteoarthritis

In individuals with osteoarthritis, joint pain, limited mobility, or muscle atrophy may occur during frog jumps, which could lead to symptoms such as leg weakness and pain. Treatment may include medications such as glucosamine sulfate capsules or diclofenac sodium sustained-release tablets, as prescribed by a physician.

5. Lumbar Disc Herniation

If a patient has lumbar disc herniation, compression of the sciatic nerve may weaken leg muscle strength, commonly causing similar symptoms. Medications such as mecobalamin tablets or acetaminophen and hydrocodone bitartrate tablets may be used according to medical advice.

In addition, this condition may also be associated with lower extremity arterial occlusive disease due to atherosclerosis. If patients experience any discomfort, they should promptly visit a hospital for evaluation and treatment to avoid delays in managing the underlying condition.
