Ageing impairs skeletal muscle function, linked to reduced subsarcolemmal mitochondrial density, fragmented intermyofibrillar networks, and lower cristae density. These mitochondrial changes strongly associate with diminished physical capacity, highlighting mitochondria’s role in age-related muscle decline.
Cracking the pain code: What your symptoms are really telling you
Pain is more than just tissue damage, it’s a protective mechanism shaped by biomechanics, biochemistry, and context. Guest author, Dr Bella Lord (MOSIC), explores how pain works, why perception varies, and how addressing lifestyle factors can help manage and resolve persistent pain.
The link between elite athletic training and slower biological ageing
Olympic champions exhibit slower epigenetic ageing compared to non-champions, with rigorous, long-term exercise from adolescence showing beneficial effects on DNA methylation. This suggests elite athletes may experience decelerated ageing, reduced disease risk, and improved healthspan, highlighting the potential of intense physical activity in promoting longevity and wellness.
High-intensity exercise reduces muscle ageing through inflammation
High-intensity interval exercise (HIIE) reduces cellular senescence in human muscles through acute inflammation, as shown by decreased p16INK4a and CD11b mRNA levels. Blocking inflammation with ibuprofen attenuates these effects, highlighting the role of inflammation in exercise-induced muscle rejuvenation and its potential for enhancing healthspan and longevity.
How senescent cells help regenerate damaged cartilage
Cellular senescence aids meniscus repair. Once thought to drive ageing, senescent cells release signals that promote healing. In rats, these cells help regenerate damaged knee cartilage. Removing them impairs recovery, suggesting that harnessing their regenerative effects could offer new strategies for joint repair and longevity.
Urolithin A boosts muscle strength and endurance in middle age
Urolithin A supplementation enhances muscle strength, aerobic endurance, and mitochondrial efficiency in middle-aged adults. It activates mitophagy, improves walking distance, and reduces inflammation markers, supporting muscle function and longevity. The findings highlight its potential as a nutritional intervention for healthy ageing
Supercharge training outcomes with precise, adaptable and barefoot training
Discover how barefoot training, precision movement, and recovery can revolutionise your fitness. Learn key principles like aligning with natural biomechanics, prioritising technique, and embracing adaptability. Whether you’re an athlete or beginner, these insights will help you build strength, prevent injury, and achieve your goals effectively.
Urolithin A and its role in optimising ageing health
Urolithin A, derived from gut metabolism, enhances mitochondrial function, reduces inflammation, and improves muscle strength and endurance. It offers potential benefits for healthy ageing but does not affect body composition or overall physical function. Further research is needed to explore its impact on various systems and its long-term benefits.
The impact of TRP channel inhibition on longevity
Aminoglycoside antibiotics, such as streptomycin, can inhibit TRP channels, disrupting calcium signalling essential for muscle and adipose tissue development. This interference may impair metabolic balance, potentially affecting healthspan and longevity.
Navigating the festive season: 6 ways to protect your health gains
The festive season doesn’t have to derail your health goals. With mindful strategies like stress management, enjoying treats without guilt, staying active, and prioritising rest, you can maintain balance and vitality. Discover practical tips to navigate the holidays with ease and enjoy the moments that matter most.
