Resistance training can reduce inflammation

In a meta-analysis of 19 randomized controlled trials in 728 older adults, resistance training reduced C-reactive protein (CRP) and improved physical function.

The resistance training programs lasted 6 to 38 weeks, with 2 to 3 weekly sessions. The exercises included squats, leg presses, bench presses, and rows, performed at 30% to 85% of 1-repetition maximum (1RM) for 1 to 5 sets of 4 to 25 repetitions. The training methods used elastic bands, body weight, free weights, or machines.

Overall, resistance training reduced CRP levels with a moderate-to-large effect size, and interleukin 6 and TNF-alpha remained unchanged. Resistance training also improved walking speed and leg extension strength and reduced body fat percentage.

Resistance training likely reduced CRP by lowering chronic low-grade inflammation, possibly through improved muscle function,[1] increased release of anti-inflammatory cytokines,[2] and reductions in body fat, especially visceral fat (a key driver of inflammation).[3] However, interleukin 6 and TNF-alpha remained unchanged, likely because interleukin 6 has both proinflammatory and anti-inflammatory roles, whereas TNF-alpha is associated with short-term rather than long-term inflammation.

Outside magazine: aging and muscle power decline by Alex Hutchinson

https://www.outsideonline.com/health/training-performance/declining-muscle-power/

It’s not just a general decline in activity, though. Subjects in Sundberg’s study wore an accelerometer to measure their daily step count as a rough estimate of their physical activity levels. There was almost no connection between daily physical activity and peak power: step count explained only 3 percent of the variance in peak power. I’m a big fan of aerobic exercise, but simply staying fit doesn’t seem to be enough to keep those fast-twitch fibers firing.

I’m venturing beyond what the study found, but the message I take from it is that if you want to hang on to as much explosive power as possible, you need to move and train in explosive ways. Plyometric exercises, which includes things like box jumps and bounding, are one approach. Another option is resistance training with lighter weights—less than about 60 percent of one-rep max, according the American College of Sports Medicine’s guidelines—where you focus on performing the movement as quickly as possible.

For the specific goal of hanging on to your fast-twitch fibers, there may also be a case for doing some heavy resistance training, with sets of six reps of fewer. If the weight is heavy enough, you’ll need to recruit your fast-twitch fibers to lift it. It’s worth remembering, after all, that power is force times velocity—so increasing the force you’re able to deliver is a key part of the equation. There’s evidence that once strength drops below a critical level, usable power drops off a cliff.

Which of these various approaches is most effective remains to be seen. For now, my plan is simple: more hill sprints.

The BEST WAYS To Heal Chronic Pain & Trauma WITHOUT Medication | Howard ...

Headaches, migraine, back, neck or joint pain, irritable bowel syndrome (IBS), fibromyalgia – they’re just some of the common causes of chronic pain, which is estimated to affect between a third to half of all UK adults, or just under 28 million of us. Emerging neuroscience tells us our brains actually create what we experience in our bodies, through a process called predictive processing. Pain doesn’t come from the body part where it’s felt, it’s created by our brain, signalling that something needs attention. #feelbetterlivemore ----- Show notes available at: https://drchatterjee.com/310 Find out more about Howard: Website https://unlearnyourpain.com/ Twitter   / hschubiner   This Might Hurt (documentary) https://www.thismighthurtfilm.com/ Howard’s books: Unlearn Your Pain: A 28-day process to reprogram your brain US https://amzn.to/41SoEqU UK https://amzn.to/3DIm7nr Unlearn Your Anxiety and Depression: A self-guided process to reprogram your brain US https://amzn.to/41QtyVe UK https://amzn.to/3WHt2WE Hidden From View: A clinician's guide to psychophysiologic disorders https://unlearnyourpain.com/hidden-fr...

The Underestimated Role of Resistance in Body Recomposition

Having a healthy body composition, with plenty of lean mass – in the form of muscle and bones – is essential for health throughout the lifespan. Achieving a healthy body composition requires a balanced approach that emphasizes resistance training – and calorie reduction where appropriate.


In this Aliquot, Dr. Brad Schoenfeld describes a balanced approach to maximizing muscle growth and strength and dispels early myths about possible blunting effects of aerobic training, the need to train to failure, and the "go heavy or go home" philosophy.


Here's what you'll find in this episode...

(00:00) Can resistance training amplify fat loss? 

(03:33) Why weight loss burns muscle — and how to prevent it 

(06:25) The role of protein in muscle preservation 

(08:21) Does aerobic exercise blunt gains? 

(16:07) The role of failure in resistance training 

(18:29) Reps-in-reserve vs. training to failure
