一項研究表明，力量訓練運動，如靠墻靜蹲和保持平板支撐姿勢，是降低血壓的最佳方法之一。英國研究人員表示，應該更新有關鍛煉身體的指導建議，該建議目前主要關註走路、跑步和騎自行車等運動對身體健康的益處。
If you’ve never planked, it involves holding the starting position for a push-up. A wall squat requires you to hold a sitting position with your back against a wall.
如果你從來沒有做過平板支撐運動，那麼它指的是身體保持俯臥撐起始位置的訓練方法。靠墻靜蹲運動則需要你保持坐姿，背部貼住墻面。
Both are isometric exercises, focusing on static strength training. According to a review of trials involving nearly 16,000 people, this type of exercise is the best way to lower blood pressure although all exercise is beneficial.
以上兩種動作都是等長運動，側重於訓練靜態力量。根據一項有近1.6萬人參與的試驗綜述，盡管所有運動都對身體有益，但這種類型的運動是降低血壓的最佳方式。
Instead of pushing up the heart rate like running, researchers say it increases tension in the muscles and then prompts a sudden rush of blood when the exercise is over.
研究人員們說，這類等長運動並不像跑步那樣會提高心率，而是會增加肌肉的張力，然後在訓練結束時引起血液的突然上湧。
