Years of research suggest that vision, lung function, immune system performance, and even sperm count can all be improved by omega-3s. A study of endurance athletes suggests that overtraining increases morning resting heart rate by about 10 beats per minute[*]. Login here Want to become an Insider for free? These are the 5 hidden dangers of overtraining, from heart rate changes to poor sleep. HRV is being touted as the new RHR when it comes to monitoring stress and recovery. I didn’t think there was much point before I read this and I think there is less reason now.

Hi Stephen, thanks for the comment, we actually posted the references at the bottom of this page if you would like to read further into the studies.

Glutamine is produced in the muscles and is used extensively by the cells of the immune system to support production of lymphocytes, white blood cells that defend the body against cancerous cells, pathogens and foreign matter. Resting heart rate refers to the frequency of your heart beats when you’re completely at rest. (2006) say HRV measurements are noninvasive and most reliable when performed under standardized conditions. Testosterone also promotes many metabolic activities, including the Muscles and bones inevitably experience damage during exercise and tend to require 24 to 48 hours of rest between workouts for adequate recovery.

I moticed that over about a month, my resting heart rate increased from 55 bpm to 70 bpm. Very interesting findings, thanks for sharing. Higher heart rate variability means that your heart rate can fluctuate between, for example, like 80 BPM and 100 BPM in frequency. Overtraining indicators in the literature were semi-reliable at best – things like resting T:C ratios, resting heart rate measures and bodyweight fluctuations tended to respond clinically only at the point of severe over-training, i.e. Meeusen et al.
