New studies highlight benefits of resistance training for lymphedema and blood pressure

Recent scientific research has identified significant health benefits from specific types of resistance training. A meta-analysis of 38 randomized controlled studies conducted by researchers in China suggests that resistance training can assist in the prevention and treatment of breast cancer-related lymphedema. The findings indicate that strength training is associated with a lower risk of developing lymphedema and can help reduce arm volume and improve arm function in patients with moderate to severe cases.

In a separate study published in BMJ Open Sport & Exercise Medicine, researchers from several UK universities investigated the effects of isometric training, specifically the wall sit, on blood pressure. The study involving 100 adults found that performing four two-minute wall sits with two-minute breaks, three times per week, significantly reduced systolic blood pressure. After eight weeks, those training three times weekly saw a reduction of 13.7 mmHg compared to a control group, whereas those training only once or twice weekly saw smaller reductions. The study noted that the benefits diminished if the training was discontinued after the initial four-week phase.
