It’s not news that exercise is good for health. However, research on which forms are best for how long and for what specific conditions has received a lot of attention lately. Perhaps the most notable recent news, given the reluctance of many patients to follow time-consuming or complex exercise prescriptions, very little daily time that may be needed (see infographic).
UK researchers It analyzed data from fitness trackers worn by more than 71,000 people. The results show that short, vigorous exercise may be more beneficial than long-term, moderate exercise. The data showed that longer exercise duration led to improved health overall, but the protective effects improved over time. Experts point out that short but intense exercise can reduce plaque that clogs arteries, improve blood pressure, and improve overall physical fitness.
This shorter-than-expected duration of exercise can help patients comply with exercise prescriptions. Centers for Disease Control and Prevention United States (CDC) currently recommended at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous exercise per week. However, only 54% of Americans Do 150 minutes of aerobic activity per week. “Lack of time is one of the main reasons people don’t exercise,” said study author Matthew Ahmadi. Therefore, it is hoped that only needing 8 minutes a day instead of 30 can convince busy patients to get the exercise they need.
Beyond exercise prescriptions for improving overall health and preventing cardiovascular disease, several recent studies have identified specific benefits in certain conditions. I know found that short aerobic exercise increased benefits Exposure therapy in patients with post-traumatic stress disorder (PTSD). Researchers randomized 130 adults (mean age: 39 years; 61% female; 76% white) with PTSD will receive nine 90-minute exposure therapy sessions with aerobic exercise or passive stretching (n = 65 in each group). Exposure therapy sessions were similar. After these sessions, the participants performed their own exercises for 20 minutes. At 6-month follow-up, greater reductions in PTSD severity were observed in the aerobic exercise group compared to the stretching group (mean difference: 12.1; 95% confidence interval). [IC 95%]: 2,4a – 21.8; p = 0.023), indicating a “moderate effect size” (D = 0.6 [0,1 a 1,1]). A mean difference of 5.7 in the Beck Depression Inventory-2 score (95% CI: 10.9 out of 0.5; p = 0.022), giving a “moderate effect size” (0.5, 95% CI 0.1 to 1.0).
Migraine is another condition where exercise can be particularly beneficial. recent research It has been shown that resistance exercise reduces migraine better than the first-line drugs topiramate and amitriptyline. Systemic review with network meta-analysis It includes 21 clinical trials with an exercise program group and a control group as a comparison. The total sample size collected was 1,195 migraineurs (mean age: 35.5 years; female:male ratio: 6.7:1). All exercise interventions were more effective than placebo in reducing migraine frequency. In terms of ranking, resistance exercise was best compared to placebo, with an average of -3.55 (95% CI -6.15 to -0.95) on migraine days per month. The next most effective interventions were high-intensity aerobic exercise (-3.13, 95% CI: -5.28 to -0.97) and moderate-intensity aerobic exercise (-2.18, 95% CI: -3.25 to -1.11) followed by topiramate. placebo and amitriptyline.
Exercise can significantly improve cognitive function of patients who have had a stroke. Results from a new proof-of-concept trial showed that patients with mild to moderate cognitive impairment regain near-normal cognition with intervention. new single-blind, single-center study120 patients (mean age: 70 years; 62% men) who had an ischemic or hemorrhagic stroke were included. They were randomized to a stronger exercise program, a cognitive training and social activities program, or a balance and toning exercise program.
At the end of the intervention, participants in the exercise group had significantly better cognitive scores than the balance and toning group (estimated mean difference -0.24, 95% CI -0.43 to 0.04; p = 0.02). However, this difference did not persist at the end of follow-up (estimated mean difference: -0.08; 95% CI, -0.29 to 0.12). “It’s intuitively and biologically logical to say that if you don’t keep doing the exercises, the benefits will wear off over time; it’s a use it or lose it,” said study researcher Teresa Liu-Ambrose. D. In conclusion, “Any core exercise can be beneficial for people in the chronic stage of stroke, and improving some of the more basic motor functions, such as balance, can translate into people’s ability and desire to engage in more physical activity.” .
From discoveries about specific conditions where prescription exercise can provide significant benefits, to recent research into general advice to patients, fitness has been a major focus of attention lately and is this week’s Top Trend.
