Exercise

Cervical exercises may help reduce disability related to migraines, but evidence for preventing headache frequency or severity remains weak and requires larger, better-designed trials.

Showing people individualised pictures of subclinical atherosclerosis may help sustain modest improvements in lifestyle choices, though the effect size is modest and long-term clinical benefit remains unclear.

Exercise may improve aerobic fitness, lower inflammation, and reduce depression in dialysis patients, but evidence quality is limited and benefits vary by exercise type.

Vigorous aerobic exercise may place greater acute mechanical stress on airway cells than moderate exercise, though the clinical significance of this finding in healthy young people remains unclear.

Exercise probably produces small, measurable but not clinically meaningful reductions in hip osteoarthritis pain and function compared to no activity.

Enzyme-derived deer velvet extract may help reduce subjective fatigue and support endurance capacity in adults with chronic fatigue syndrome, though a single trial of 100 participants is not yet definitive.

Community-based programs, especially those using digital platforms or peer leaders, may help adults in resource-limited settings increase physical activity, though the heterogeneity of studies limits firm conclusions about which approach works best.

Adding wearable sensor feedback to home-based digital rehabilitation after hip replacement is associated with faster early recovery, better adherence, and improved quality of life and mood, without additional cost—though the long-term hip-function benefit was smaller than the minimum clinically meaningful difference.

Fewer sprints per session appear sufficient to build aerobic fitness, which may reduce physical discomfort and dropout rates while preserving the time-efficiency advantage of SIT.

Telerehabilitation via mobile or web platforms may be a viable alternative to center-based cardiac rehabilitation for improving exercise capacity and engagement after heart procedures, though traditional risk-factor improvements occur similarly in both settings.

Lifestyle modification, particularly when combining diet and exercise, may help reduce fat stored within the pancreas—though the absolute reduction is modest and longer-term follow-up studies are needed.

Acute cold-water immersion may modestly reduce subjective soreness but does not meaningfully improve strength recovery and may temporarily impair explosive power immediately post-exercise—timing and context matter for its practical use.

Structured cardiac rehabilitation may help reduce cardiovascular risk and blood pressure in carefully selected patients with both rheumatoid arthritis and hypertension, without worsening inflammatory disease control.

Structured physical activity may be associated with small reductions in BMI and body fat in young children with obesity, but current evidence is too limited and uncertain to draw confident conclusions about effectiveness.

Regular physical activity may be associated with slower biological aging as measured by specific DNA methylation clocks, though evidence remains observational and causation is not yet established.

Different exercise types appear to target different aspects of body composition, so choosing an exercise mode may depend on whether your priority is overall weight loss, fat reduction, or specific measurements like waist or hip circumference.

Physical exercise may enhance inhibition and working memory in individuals with substance use disorder, suggesting it could be a useful complement to standard rehabilitation.

Combined aerobic and resistance training may help lower blood pressure in people with hypertension as part of an overall treatment plan, though the magnitude of benefit appears modest and complementary to, not a replacement for, medical management.

Supervised aerobic exercise is feasible and may improve cardiovascular fitness in night-shift nurses, though this small trial did not detect changes in cardiometabolic risk factors or body composition over 12 weeks.

Combined lifestyle programs that address diet and exercise together may help cancer survivors manage several cardiometabolic risk factors, though individual gains tend to be small.
