Exercise after thoracic aortic disease — no serious adverse events across nine studies
A scoping review of nine studies in thoracic aortic disease found physical function generally improved and no serious adverse events occurred. Systolic blood pressure responses, however, varied greatly.
Strength improved in difficult-to-control asthma — what changed was muscle, not lungs
In a triple-blind randomised trial, adding photobiomodulation to resistance training improved peripheral muscle strength and exercise capacity further. Neither arm improved lung function or asthma control.
In aged rats, resistance training alone barely raised the growth signal
Eight weeks of training on its own produced only mild increases in mTOR and IGF-1 signalling. The significant rise appeared only when probiotics, vitamin D and leucine were added.
A high-protein diet cut gut microbial richness — and training did not restore it
In mice fed 60% of energy as protein, gut microbial richness fell, and eight weeks of resistance training did not bring the community back. What training changed was performance.
Blood sugar benefits peaked at 704 MET-minutes of exercise per week
A dose-response meta-analysis in older adults with type 2 diabetes. HbA1c reduction maxed out near 704 MET-min/week, and pushing past it did not keep the curve climbing.
COPD is a muscle problem too — and lifting was feasible even with severe obstruction
Chronic obstructive pulmonary disease damages skeletal muscle, not just lungs. Resistance exercise improved lower-limb function and stayed feasible under significant dyspnoea.
Combining cardio with lifting cut inflammation more than either alone
A network meta-analysis of 28 randomised trials in metabolic syndrome. Combined training ranked first for both CRP and TNF-α; resistance alone only led on IL-6.
An athlete's enlarged heart and a diseased one differ at the RNA level
Cardiac hypertrophy is not one phenomenon. Specific lncRNAs distinguish exercise-induced from pathological growth — and some encode an antihypertrophic memory.
Biological aging sped up during chemotherapy — and only the lifting group stopped the acceleration
In a randomised trial of colon cancer patients, GrimAge acceleration rose 0.45 SD over six months in usual care alone. The resistance training group showed no significant acceleration.
Mood benefit peaked at 801 MET-minutes a week and stopped climbing
The relationship between exercise volume and depressive symptoms is not a straight line. Across 31 randomised trials and 2,247 people, the curve flattened at a moderate dose.
Training raised peak VO2 by 2.3 in 205 patients with a thickened heart
Hypertrophic cardiomyopathy long meant scaling exercise back. Pooled data now shows gains in capacity, with adding resistance work no worse than endurance alone.
There is still no exercise prescription for pregnancy hypertension — 13 studies in 17 years
Only 13 studies published between 2008 and 2025 tested structured exercise in women at high risk of or diagnosed with hypertensive disorders of pregnancy. The direction is mostly favourable, but intensity and safety criteria are too inconsistent to build a prescription from.
Losing weight during adolescence can lower the muscle and bone ceiling for life
GLP-1 drugs clearly improve weight and cardiometabolic markers in pediatric obesity. The complication is that the treatment window overlaps the one period when muscle and bone accrue fastest.
Eleven weeks of lead-leg strength work added 2.8 km/h to shot speed
Twenty-nine youth elite field hockey players were randomised, and one group added six lead-leg exercises twice a week. The controls stayed flat; the trained group got 3.4% faster.
BDNF rose over 30% after light high-rep sets, not heavy ones
Nine women aged 65+ completed all four resistance training modalities. Only the low-set, high-repetition protocol produced a significant post-exercise rise in serum BDNF.
Cholesterol rises at menopause, not with age — and the sharpest change lands within a year of the final period
LDL cholesterol and triglycerides climb during the menopause transition independently of chronological ageing, with the largest increases inside one year of the final menstrual period. Regular aerobic or resistance training is named as a mitigation.
In oestrogen-deficient mice, resistance training protected bone better than running
Sixty-four ovariectomised mice trained for eight weeks; the ladder-climbing group beat the treadmill group on bone-formation markers. This is an animal study, so it points at a mechanism, not a prescription.
Brain health runs through muscle and arteries: the muscle-vascular-brain axis
The brain has long been treated as a top-down regulator. This synthesis argues the traffic runs the other way too, through myokines from skeletal muscle and stiffness in the arteries.
A case report proposes that muscle lost while dieting can push blood sugar back up
This is a hypothesis built from one patient's course, not a trial. Weight fell from 84kg to 70kg while strength declined and fasting glucose climbed to 300 mg/dL.
Stretch grows muscle longer, not thicker — and mTORC1 was the switch in rodent diaphragm
In rat and mouse diaphragm, mechanical stretch produced longitudinal growth, and blocking mTORC1 abolished it. This is surgical mechanism work in rodents, not a human lifting the bar in a stretched position.
