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.
Back Injuries Hockey players are at risk for low-back injuries due to the flexed (forward) posture of skating and the frequent hyperextension (backward) stress. Low-back pain and/or a pulled muscle are the most common injuries. Stretching of the hip flexors along with strengthening of the back and abdominal muscles will help avoid these injuries.
