Cardiac remodelling: concentric versus eccentric hypertrophy in strength and endurance athletes (2008) -> The part "Remodeling: endurance vs. strength training" ("Figure 1" in that part and the explanations around it).I would respectfully request some evidence for these two very strong statements. To wit:
- strength training induced maladaptive left ventricular hypertrophy, and;
- stiffening of heart muscle leading to diastolic disfunction and early death.
Regarding strength/resistance training: "...As a consequence, the wall thickness increases. This pathological condition is called concentric hypertrophy (figure 1).Combined with a reduced compliance due to increased stiffness of the ventricle, this leads to diastolic dysfunction."
Effects of Resistance Training on Ventricular Function and Hypertrophy in a Rat Model (2007)-> "Although diastolic function was not completely investigated, we cannot exclude the possibility that resistance training results in diastolic dysfunction."
Resistance training and cardiac hypertrophy: unravelling the training effect. - PubMed - NCBI (2002)-> States that there are no negative effects to the left ventricule. Oldest study, so maybe outdated by the newer ones.
Included it nonetheless to show that there's still a debate going on.
Also the book (and referenced studys in there) "The Cardio Code", which is the main thing that raised my awareness about this.
I should have phrased everything I wrote in my original post as "can lead to". It's not like every powerlifter out there dies by the age of 50 through a heart attack caused by diastolic dysfunction...
