1. Trainingwell supported · human data

   Pooled results from seven randomised trials in 344 adults aged 60 and over found that resistance training programmes of at least eight weeks increased bioelectrical phase angle by 0.52 degrees, a marker of cellular health read from body composition devices.

   What it shows: A consistent finding on a thin base: pooled from just seven trials with 344 older adults in total. The authors say more rigorous studies are still needed to work out which equipment and protocols get the most out of the effect.Meta-analysis · Rev Endocr Metab Disord

2. Mindwell supported · human data

   Pooled results from 22 trials found exercise therapy improved global cognitive function and reduced depression in older adults with mild cognitive impairment. Aerobic exercise was the most effective type, while multicomponent and neuromotor exercise did not improve cognition, and cognitive gains grew with higher exercise frequency.

   What it shows: A reasonably strong signal: results pooled from 22 trials in older adults with mild cognitive impairment showed a meaningful cognitive benefit. The depression finding rests on just 7 of those trials, and the studies varied in the exercise types and doses they tested.Meta-analysis · Arch Gerontol Geriatr

3. Longevitywell supported · human data

   Across 22 randomised trials, adding protein supplementation to exercise training improved frailty status, lean mass, leg strength and walking speed in frail older adults. Protein paired with resistance training gave the clearest lean mass gains.

   What it shows: Solid for direction, modest in size: results pooled from 22 trials where frail older people were assigned at random to protein plus exercise or a comparison group. Study quality averaged 6.7 out of 10 and the programmes varied, so the best formula is still unsettled.Meta-analysis · Nutrients

4. Trainingwell supported · human data

   Pooled results from 18 trials in 1,591 adults aged 50 and over with osteoporosis linked exercise, especially resistance training, to better health-related quality of life across both physical and mental domains. Programmes shorter than 20 weeks produced the most consistent benefits.

   What it shows: Promising with a wrinkle: pooled results from 18 trials in 1,591 older adults, and the clearest gains came from resistance training with moderate-certainty evidence. But when every trial was lumped together across their different questionnaires the overall effect washed out, so the headline benefit rests on smaller comparisons.Meta-analysis · PeerJ

5. Trainingwell supported · human data

   Ranking nine strategies across 24 randomised controlled trials in 1,298 older adults with sarcopenic obesity, resistance training came out best for improving handgrip strength and reducing fat mass, while multicomponent training ranked highest for lowering BMI and percentage body fat. No intervention significantly improved skeletal muscle index.

   What it shows: As strong as this kind of comparison gets: results pooled from 24 trials in 1,298 older adults, ranked against each other in one network. The programmes varied widely and no approach clearly improved the muscle index itself, so the win is on strength and fat, not on rebuilding muscle.Meta-analysis · Front Public Health

6. Trainingwell supported · human data

   In healthy adults aged 60 and over, resistance training lowered the inflammatory marker C-reactive protein and improved leg strength and six-minute walk performance, according to a pooled analysis of 19 trials with 728 participants. Two other inflammatory markers, TNF-α and IL-6, did not change significantly.

   What it shows: Fairly trustworthy on the big picture: results pooled from 19 trials in 728 healthy over-60s, all of which assigned people to lifting or a comparison group at random. The catch is that only one of three inflammation markers moved, and the trials used different programmes, so the best way to train for this effect is still unknown.Meta-analysis · Arch Gerontol Geriatr

7. Trainingwell supported · human data

   Pooling 15 randomised trials of 587 men and women aged 60 and over with overweight or obesity, resistance training of at least eight weeks improved body weight, percent body fat, fat mass, BMI and lean mass, yet the spread of results showed no true differences between individuals in how much they responded.

   What it shows: Reasonably solid: results pooled from 15 trials in 587 people aged 60 and over who were carrying extra weight, all training for at least eight weeks. It does not prove individual variation is absent, only that the trials' own numbers give no evidence for it once random variation is accounted for.Meta-analysis · Sci Prog

8. Cardiowell supported · human data

   Pooling 22 randomised trials of 552 men and women aged 60 and over, resistance training raised VO2max by an average of 1.8 ml/kg/min compared with controls, and again showed no evidence of true differences between individuals in how much they responded.

   What it shows: Decent evidence for a small effect: results pooled from 22 trials in 552 people aged 60 and over. The trials disagreed considerably with each other and the plausible range of outcomes ran from a slight decline to a clear gain, so improvement is not guaranteed for any one person.Meta-analysis · Sci Prog

9. Supplementswell supported · human data

   Meta-analyses indicate that combining creatine supplementation with resistance training improves ageing muscle mass and upper body strength beyond resistance training alone, and creatine also shows promise for bone mineral density and indices of bone biology.

   What it shows: Reasonably solid for muscle and upper body strength: the conclusion rests on pooled trials of creatine combined with resistance training in the context of ageing. The bone findings are promising rather than proven, and the abstract does not report how large the added benefits are.Meta-analysis · Endocrine

1. Longevitywell supported · human data

   Across seven randomised trials with 558 community-dwelling adults aged 60 and over with sarcopenic obesity, exercise alone or with dietary supplements increased grip strength by 1.30 kg, gait speed by 0.05 m/s and appendicular muscle mass by 0.40 kg, while cutting waist circumference by 1.40 cm and total fat mass by 1.77 kg.

   What it shows: A consistent signal with modest sizes: results pooled from seven trials in 558 older adults, and the gains, like 0.05 m/s of walking speed, are real but small. The authors still call for better-designed trials to work out which exercise or supplement mix does the work.Meta-analysis · Maturitas
