Weighted regressions were used for abdominals and sternopleurals as the sample sizes were not constant for all populations.
Losses of quantitative versus molecular variation best-fitting quadratic relationships for our experiments, the predicted values of proportions of quantitative genetic variation retained were 0.90 for abdominals and 0.66 for sternopleurals.
The longest median suture is between the abdominals and the shortest is between the gulars, which equals about one half that between the humerals.
The suture between the pectorals is not shorter than the suture between the abdominals.
The plank strengthens the abdominals, back, and shoulders.
The equipment is mainly used for the lower back, but can also target the gluteal muscles and the abdominals.
It is a convergence of the diaphragm and the abdominals, so that when both sets of muscles (diaphragm and abdominals) tense, the epigastrium pushes forward.
While breathing and engaging abdominals in this position, no strain should be felt through the lower back.
