If you're training for #muscle strength, power, or hypertrophy, STOP ice bathing after your sessions. It's almost certainly diminishing your returns. 1/5 #strength#training Evidence summary ->
Exhibit 1. Cold-water immersion blunts the muscle's anabolic response to strength training. @JPhysiol@LlionARoberts 2/5
Exhibit 2. Cold-water immersion lowers the muscle's capacity for myofibrillar protein synthesis after resistance exercise. @JPhysiol@27CJ 3/5
Exhibit 3. Cold-water immersion has a deleterious effect on adaptations to resistance training (SR and meta-analysis). @SportsMedicineJ@BlueSpotScience 4/5
Ice bathing / cold-water immersion has its benefits. But strength or resistance training will likely suffer. The practice endures because of popularity, not efficacy. 5/5

I learned about this study after Dr. Rhonda Patrick (Ph.D. in biomedical science) shared it among her nearly 400,000 Twitter followers who, in turn, retweeted it more than 500 times. 🧵3/13
I was asked recently to provide some examples of health and fitness marketing that makes false claims and/or exploits human biases. I came up with a billion examples. Here are just 6:
The official #Olympics website endorsing #cryotherapy as an effective form of post-exercise recovery. Despite the fact the literature is very unimpressive, littered with low-quality studies, and tiny effects. #IOC
