In mathematics, binomial coefficients are represented as \(\binom{a}{b}\), where \(a\) is the \((a-1)^{\text{th}}\) row, and \(b\) is the \((b-1)^{\text{th}}\) number in that row, counting from the left, acting as an index.
Hockey is a team sport that incorporates balance, endurance, and hand-eye coordination. Choosing the proper hockey equipment is important to protect from injuries or dental damage. Hockey players need to drink plenty of water because the heat and weight of the equipment can cause dehydration.
Ice hockey is truly a full-body sport, so the entire body should be trained to prepare for the stress of hockey. However, it is wise to strengthen the core first and foremost as this is where movement starts. It is also important to have a strong core because it provides stability, deceleration of force, and force production during the hockey game.
