What is the purpose of this trial?

This trial aims to determine if a 12-week exercise program can assist men experiencing urination difficulties due to an enlarged prostate, known as benign prostatic hyperplasia (BPH). Participants will either follow a personalized exercise plan or receive health education to assess which approach improves symptoms. The trial targets men aged 60 or older who have moderate-to-severe urination issues and have been mostly inactive. The study seeks to provide insights into whether exercise can effectively treat BPH symptoms. As an unphased trial, it offers participants the chance to contribute to valuable research that could lead to new non-invasive treatment options for BPH.

Will I have to stop taking my current medications?

The trial requires that participants do not start, stop, or change their BPH medications or other medications affecting urinary symptoms for the entire study period of 7 months, unless necessary by their clinician.

What prior data suggests that this exercise intervention is safe for older men with LUTS/BPH?

Research has shown that exercise can safely help manage symptoms of an enlarged prostate. Studies have found that regular physical activity may reduce the risk of developing benign prostatic hyperplasia (BPH), or an enlarged prostate, by half compared to inactivity. This indicates that exercise is generally safe and could ease symptoms without major risks.

One study found that spending less time sitting also seemed to protect against BPH, further supporting the idea that staying active is beneficial. While exercise doesn't prevent BPH from developing, it does help reduce the symptoms. Overall, evidence suggests that exercise is a safe and helpful way to support prostate health. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for an enlarged prostate, which often include medications like alpha-blockers and 5-alpha-reductase inhibitors, as well as surgical options, the use of exercise offers a non-invasive alternative with potentially fewer side effects. Researchers are particularly excited about this approach because it not only aims to alleviate symptoms but also promotes overall health and wellness. The unique aspect of using exercise is that it could improve prostate health while enhancing cardiovascular fitness and mental well-being, offering a holistic benefit that standard medication or surgery might not provide.

What evidence suggests that exercise might be an effective treatment for an enlarged prostate?

Research has shown that physical activity can help reduce symptoms of an enlarged prostate. In this trial, participants in the Exercise Arm will undergo a personalized 12-week exercise program. Studies have found that men who exercise frequently experience fewer urinary problems related to benign prostatic hyperplasia (BPH). Engaging in moderate to vigorous exercise may lower the risk of these symptoms by up to 25% compared to inactivity. Additionally, running longer distances each week might decrease the chance of developing BPH, regardless of weight or diet. Regular physical activity is associated with a significantly lower risk of BPH. ^{2 6 7 8 9}

Published Research Related to This Trial

A systematic review of 21 trials involving 1748 prostate cancer patients found that resistance exercise significantly improved body composition, functional capacity, and muscle strength, with a notable reduction in fat mass and an increase in lean mass.

The study suggests that lower volume resistance training at moderate to high intensity is just as effective as higher volume training, which may help make exercise more accessible and encourage adherence among patients.

A review of 14 studies indicates a strong inverse relationship between exercise and the development of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS), suggesting that a healthy lifestyle can significantly impact prostate health.

Proposed mechanisms for this relationship include reduced sympathetic nervous system activity, prevention of metabolic syndrome, and decreased oxidative damage to the prostate, highlighting the importance of exercise in maintaining prostate health.

Men aged 45 and over with sedentary or light occupational work had a higher risk of incidental prostate cancer, with an odds ratio of 1.9, indicating a significant association between low physical activity at work and prostate cancer risk.

Conversely, higher levels of occupational physical activity were linked to a reduced risk of prostate cancer, with odds ratios decreasing from 1.0 for sedentary jobs to 0.2 for high/very high activity levels, suggesting that being more active at work may help lower the risk of developing prostate cancer.
