Agonist muscles and antagonist muscles are the muscles that cause or inhibit a movement. Agonist muscles cause a movement to occur through their own activation, whereas antagonist muscles produce an opposite joint torque to the agonist muscles controlling the movement.  

Hamstrings are the group of the muscles and tendons located in the upper leg. They include the biceps femoris, semimembranosus and semitendinosus which play an important role in walking, running and jumping. They bend the knee and move hip backward. The muscle that is antagonist to the hamstrings are the quadriceps. Quadriceps are the group of muscles located in the front of the thigh which include the vastus lateralis, vastus medialis, vastus intermedius and the rectus femoris. They help in extending or straightening the knee. Hamstrings contract to bend the legs and the quadriceps relax. Quadriceps contract to straighten the leg and the hamstrings relax.

The correct answer to this open question is the following.

Unfortunately, you did not include the two maps. Without them, we do not know your specific reference.

However, trying to help you and after doing some deep research, we can say the maps portray the Spanish, British, and Dutch trade maritime routes from 1750 to 1850. The other map shows the many trade routes in 2010 that practically crossed all over the world.

That is why we can answer that one significant reason for changes in the patterns of global economic interactions from circa 1750 to circa 2000, as illustrated by the two maps are the technology and modernization of means of transportation that today include land, air, and sea.

Trade has been the activity that has developed most rapidly all over the world in those years. Today, there are international organizations and free trade agreements that connect the world through trade.

More people on the planet started to require more products from all places and developed nations exploited natural resources and raw materials and produced more and better goods in their industrialized cities that were exported.
