Rugby involves handling, running, kicking, pushing and pulling so that just about every muscle is used.
what is the muscle that acts as a sucking
Muscle shrinkage, or muscle atrophy, can be caused by lack of use (such as immobilization or inactivity), nerve damage, malnutrition, aging, or certain medical conditions like ALS or muscular dystrophy. It can also occur as a result of a decrease in muscle protein synthesis or an increase in muscle protein breakdown.
The Orbicularis oris muscle. It is sometimes known as the kissing muscle because it is used to pucker the lips.
If muscle contractions use ATP at or below the maximum rate of ATP generation by mitochondria, the muscle fiber will be able to sustain the contraction for a longer period without fatigue, as the ATP production can meet the energy demands of the muscle activity.
I am becoming a huge fan of rugby, so this is a fun question. I notice that very solid body types with higher weights (not overweight..just large guys) is definitely an advantage in rugby during scrums and tackles. Running, catching and kicking are areas where the lighter, taller men seem to excel. It would seem that a good rugby team has part of the line who are larger in muscle mass and heavier to help to win scrums and for good, solid defensive lines and good tackles, but there are also some taller, lighter men who handle the ball better in passing and running.

It's 50/50 they do and they don't. But rouphly they do.
In rugby when you are pushing against each other( in a rugby scrum) your muscles contract but stay the same length and this is isometric contraction. Even though you are using a lot of force your muscles stay the same length.
You use a rugby ball to play rugby. It is shaped like an egg.
