Background A growing body of evidence suggests that physical activity and exercise may improve erectile function. Objective To conduct a systematic review and meta-analysis evaluating the effects of physical activity modalities and exercise on erectile function in erectile dysfunction trials. Methods A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. We searched 6 electronic databases between January 1990 and July 2016 and hand-searched reference lists for randomised controlled trials. Only patients with a diagnosis of erectile dysfunction were included. The mean differences between intervention and control groups were calculated for meta-analysis. Results 7 studies were eligible, including 478 participants allocated to aerobic, pelvic or combined exercise interventions. Follow-up ranged from 8 weeks to 2 years. The risk of bias in the trials was deemed moderate to high mainly due to impossible blinding of patients and personnel, as well as questionable blinding of outcome assessors. Random-effects meta-analyses were performed. Pooled data showed a statistically significant improvement in erectile function score (mean difference 3.85, 95% CI 2.33 to 5.37). A benefit was still demonstrable after a sensitivity analysis because the mean difference in International Index of Erectile Function (IIEF) score ranged from 3.39 (95% CI 1.92 to 4.87) to 4.28 (95% CI 2.54 to 6.02). A benefit was also detected in short-term and long-term interventions as well as in trials evaluating physical activity and exercise alone or in addition to usual care. Conclusions The present study suggests that physical activity and exercise interventions improve patient-reported erectile dysfunction, particularly aerobic exercise with moderate-to-vigorous intensity.

Background Physical activity is a cornerstone of type 2 diabetes treatment and control. Aim We analysed and synthesised the guidelines and recommendations issued by scientific organisations, regarding exercise prescription for patients with type 2 diabetes. Method A systematic bibliographic search in Pubmed, Web of Science and Scopus databases was conducted. Clinical guidelines from major international scientific organisations in the field of diabetology, endocrinology, cardiology, public health and sports medicine were also considered. 11 publications were selected. Results Published guidelines recommend a weekly accumulation of a minimum of 150 min of aerobic exercise at moderate-to-vigorous intensity spread over a minimum of 3 days per week. Resistance exercise for muscle strengthening is also recommended at least 2 days a week. Flexibility exercises may complement other types of exercise. Combining aerobic and resistance exercise within the same exercise session is recommended by most guidelines. Conclusions Exercise prescription for individuals with type 2 diabetes should include specific information on the type, mode, duration, intensity and weekly frequency. The exercise strategies must be adapted for each individual, based on comorbidities, contraindications and realistic personal goals.

To compare the long-term effects of two community-based exercise programs on fall risk factors, such as balance, postural control, mobility and leg strength, in community-dwelling older men. Single-blinded randomized controlled trial, comparing three groups, with follow-ups at eight, 16, 24 and 32 weeks. Older men independent-living residing in Maia city, Portugal. A total of 66 older men (aged 69.0 ±4.9 years) were randomly assigned to an aerobic exercise group (n = 22), a combined aerobic and resistance exercise group (n = 22) or a control group (n = 22). Both community-based exercise programs consisted of three sessions each week for 32 consecutive weeks and were planned for moderate-to-vigorous intensity. The control group had no exercise intervention. Main outcomes were measured by the Timed Up and Go Test, functional reach test, 30-second chair stand test and 6-minute walk test, on five different occasions. Repeated measures of analysis of covariance revealed significant main effects between time × group interaction in all outcomes over time (Timed Up and Go Test: p < 0.001; functional reach test: p = 0.002; 30–second chair stand: p = 0.001; 6-minute walk test: p < 0.001). Both exercise groups reported improvements; however, better performance was identified in the combined aerobic and resistance exercise group compared with the aerobic exercise group (–20.3% vs. –9.1% on the Timed Up and Go Test, +27.5% vs. +10.9% on the functional reach test, +20.8% vs. +7.3% on 30-second chair stand, +10.9% vs. +3.5% on 6-minute walk test). Adding resistance exercise to aerobic exercise improves factors associated with an increased risk of falls. However, both exercise regimes, combined or aerobic alone, are more effective than no exercise in the reduction of fall risk factors. ClinicalTrials.org #NCT01874132
