Hypertrophy and metabolic stress. Should (could) skeletal muscle contain less buffers for metabolic stress, to inflict more hypertrophy?
For instance H+ can be buffered by carnosine.
-Would resistance training with focus on hypertrophy not have less ingestion of "buffers" or potential "buffers" to increase potential of metabolic stress and super compensation?
-This in relation to weight lifting in which "buffers" can assist in more contraction and power output?
Hi,
Maybe is not a good option for healthy and young people, if we consider that the main mechanism for promoting muscle hypertrophy is mechanical tension. In fact, recent findings support no diference in total lean mass between 5-SET to 10-SET with same repetions number ("However, a decrease in lean leg mass was observed within the 10-SET group between six and 12 weeks (p = 0.02)") (Hackett, D. A., Amirthalingam, T., Mitchell, L., Mavros, Y., Wilson, G. C., & Halaki, M. (2018). Effects of a 12-Week Modified German Volume Training Program on Muscle Strength and Hypertrophy—A Pilot Study. Sports, 6(1), 7.).
Furthermore, it is well-known that buffers capacity is related to better muscle perfomance (Parkhouse, W. S., & McKenzie, D. C. (1984). Possible contribution of skeletal muscle buffers to enhanced anaerobic performance: a brief review. Medicine and Science in Sports and Exercise, 16(4), 328-338.) and muscle health.
The interesting point of metabolic stress (i.e., vascular occlusion) is that it might be a nice approach in elderly or injured people, but more research is needed.
