Which press-up produced a net vertical force of 575 vs. 856 N on the force plates shown in the diagram?

Did you say A = 856 N and B = 575 N?

Could you use the diagram in the middle to explain the differences?

It is a diagram of the force-length relationship and I have placed A and B on the curve denoting that as muscles extend to greater or longer lengths (anterior deltoids and triceps in this exercise) they lose force capability.

Can you explain A and B from an actin-myosin overlap perspective?

What is the functional significance of training at shorter muscle length vs. longer muscle lengths?

Which muscle length training causes greater hypertrophy?

Which type of training is less likely to produce distal region hypertrophy?

So many questions? If you know the answers, all good? However, if you don’t you might enjoy a top up, check out our Eccentrics, Concentrics and Isometrics Online Course.

A shout out to Brad Thorpe and his MSK isorack, perfect for studying the force-length relationship and training at short and long muscle lengths.
