This systematic review and meta-analysis finds that cross-education—contralateral resistance training of the non-immobilised limb—is likely to attenuate losses in muscle strength and size during immobilization.

Important paper from a group with established expertise in glutathione measurements, presenting a simple assay to measure GSH/GSSG ≈ 681:1 in 10 μL of blood, including capillary, using a spectrophotometer.

Useful for exercise/nutrition/clinical studies.

Volume vs Intensity? The science just answered it.

A massive 2025 meta-analysis (6,000 participants) breaks it down:

1. Mitochondria ↑ across ALL training styles
- Endurance: +23%
- HIIT: +27%
- Sprint: +27%

2. Time efficiency matters
- Sprint training = 2–3x more gains per hour

3. VO₂ max improves regardless of method
~9–12% increase across the board

4. Capillaries favor endurance work
~ +5–10% greater density vs HIIT/sprints

5. Beginners win big
- Lower fitness = larger gains
• Age, sex, health status? No major limitations to improvement

Bottom line:
Intensity saves time. Volume builds the engine. Consistency wins everything.
