- Exercise Lowers One Key Inflammation Marker in Frail Seniors, But Not OthersStrongn = 1,2972026Frontiers in immunologyLooking at dozens of trials in older adults with frailty or muscle loss, researchers checked whether exercise calmed chronic inflammation. Exercise meaningfully lowered TNF-alpha, an inflammatory protein linked to muscle wasting. But it did not budge two other common inflammation markers, IL-6 and CRP. So exercise helps with inflammation in frail seniors, but only partially.
- How Exercise Quiets a Muscle-Wasting Inflammation Signal in Older WomenModerate2026Journal of sport and health scienceScientists found a specific inflammation signal called CXCL2 that climbs as muscle loss gets worse with age. In older adults, higher levels tracked with weaker strength and worse mobility. A year of structured exercise sharply lowered this signal and improved strength, while non-exercisers kept declining.
- Cardio vs. Weights for Type 2 Diabetes: Different Wins for EachModeraten = 2,7412026Diabetes, obesity & metabolismIn 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.
- Resistance Training Plus Amino Acids Beat Either Alone for Muscle in Older WomenModeraten = 962026Journal of the International Society of Sports NutritionIn 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.
- Vitamin K2 Didn't Help Muscle Recovery in This 12-Week TrialModeraten = 712026Medicine and science in sports and exerciseAfter 12 weeks of daily vitamin K2 supplements, neither young nor older adults saw improvements in muscle strength, soreness, or physical function after a tough leg workout. Some secondary measures in older adults showed small shifts in muscle activation speed and a damage marker at 72 hours. But the main outcomes were all null. The researchers say the age-specific signals need more study before drawing conclusions.
How this map is computed
A mark's size is the number of papers we hold on that pairing. It is a count, not a weighting by study design or sample size.
The fill shows the strongest grade in the cell. One Strong paper among four Preliminary ones still fills it dark, so open the cell to see the rest.
Grades and verdicts are assigned by a named person, never by counting.
An empty cell is a finding: nobody in our library has run that trial yet.
