What is the Longevity Research Library?

The Longevity Germany Research Library curates recent peer-reviewed studies on longevity, nutrition, exercise, sleep, and supplements. Each study is rated by evidence strength: Strong, Moderate, or Preliminary.

How are evidence levels determined?

Evidence levels are based on study type (meta-analysis, RCT, cohort study), sample size, journal impact factor, and reproducibility of findings.

66 studies

Cardio vs. Weights for Type 2 Diabetes: Different Wins for Each

In adults with Type 2 diabetes, cardio and resistance training help in different ways. Aerobic exercise was best for boosting adiponectin and lowering leptin, two hormones tied to fat regulation. Resistance training showed bigger drops in inflammatory markers like TNF-alpha and IL-6, especially in younger or overweight people. The authors caution these results are hypothesis-generating, not firm exercise prescriptions.

Exercise Helps Older Adults With Sarcopenic Obesity, but Evidence Quality Is Mixed

Pooling 20 trials of older adults with sarcopenic obesity (low muscle plus excess fat), exercise reduced body fat, BMI, and LDL cholesterol while boosting muscle mass, grip strength, and walking speed. Resistance training stood out for building muscle and strength. Combined training (resistance plus cardio) improved the broadest range of outcomes. However, the authors caution that evidence quality was only moderate for body composition and low for metabolic benefits.

Strength Training May Reshape Brain Markers in Older Adults With Early Alzheimer's Signs

A 24-week strength training program altered Alzheimer's-related brain signatures in cognitively healthy older adults. The effect was strongest in participants who already had amyloid buildup in their brains. Those reductions in brain thickness markers were linked to better executive function, suggesting the changes were adaptive rather than harmful. This was a small trial of 90 people around age 72, so the results need replication.

Why Even One Workout Sharpens Your Thinking, According to Research

A single session of moderate to vigorous exercise reliably boosts executive function, processing speed, and working memory in adults. Cardio led the pack, but resistance training also improved executive function in many trials. The brain benefits seem tied to short-term spikes in BDNF, lactate, and prefrontal brain activity. So even one workout appears to give your brain a temporary lift.

Resistance Training Plus Amino Acids Beat Either Alone for Muscle in Older Women

In healthy women aged 65 and older, combining resistance exercise with essential amino acid supplements for 12 weeks increased muscle mass more than doing either one alone. The combo group also showed the biggest improvements in fitness tests and the best shift in muscle-related hormones. Inflammatory markers dropped too, with one key marker only declining in the combined group. Each intervention helped on its own, but pairing them produced clearly stronger results.
