  1. Individual factors that effect performance in sport
    1. Age
      1. Strategy
        1. Motiation
          1. Reaction Times
            1. Agility/Mobility
              1. Anthropometry/Somatatype
                1. Ectomorph
                  1. Narrow-shaped body with little fat or muscle. Ideal body type for long-distance runners.
                  2. Endomorph
                    1. Pear-shaped body, wide hips, wide shoulders, can have a lot fat on body, arms and thighs. When fit, ideal body type for weightlifting, wrestling
