study the effect of muscle loading (i.e., use of muscles and
putting weight on them), researchers have used so-called hindlimb
suspension (up to 21 days) in rats (i.e., Alway et al., 2001;
Mortreux et al., 2019). For example, useful to study the effects of
muscle unloading during space travel. Besides muscle mass can be
reduced during unloading, what effect do you think this suspension
method has on the cardiovascular system of the rat during such
experiments?
