Here are descriptions of the events you see above from the WEIO website:

Ear Pull

In this event, there are two people sitting down facing each other with twine looped around each other’s ear – right ear to right ear, left to left. The two begin a “tug-of-war” to see who the winner is. Best two out of three wins the match. There are times when the loop will slip off one opponent’s ear – that person is the loser of that round. Each participant alternate each round using alternate ears. A game of stamina to pain, the victor demonstrates he/she can withstand pain, a trait sometimes needed to survive the harsh realities of the North.

Two-foot High Kick

This event is similar to the one-foot high kick with the difference being the athlete jumps off the floor using both feet, hits the suspended target with both feet together, and maintains balance upon reaching the floor. When landing both feet must touch the floor at the same time.

Years ago, in the coastal whaling villages, in order for the village to know that a whale has been taken, a runner would run back to the village and when within sight of the village, the messenger would jump and kick both feet into the air while running. In that manner, the people of the village would know a what was caught and prepare themselves to help in “beaching” the whale.
