Certain sports are played alone. Certain are played as part of a team. Weight lifting, for example, is usually done alone. Football, on the other hand, must be played as part of a team. It requires team coordination and the results depend on everybody either working or not working together. Team sports are more yang.
Then there is competition, either individual or group. Competition is yang, an expression of energy becoming more and more contracted or condensed. Yin activities are those in which energy moves out to the periphery. The game of solitaire is very yin! Then there are social card games, played with others for fun: those are more balanced. Serious gambling, with direct competition, is by far the most yang. A social card game is more harmonious, played just for fun, either won or lost. It is more yang than solitaire because it requires social interaction.
Any sport you do by yourself is yin and has a yinnizing effect. Anything you do in a group becomes more yang, whatever it is. If you add competition to that, it becomes even more yang.
I hope you choose a good activity for yourself today!
