Lecture 3: executive control is impaired directly following a concussion, plan what it is you want to do, know what it is you want to do, inhibit - ex. 26 or greater on mmse (mini-mental state exam) generally are in good cognitive shape, very simple test. Moca (montreal cognitive assessment) more dif cult/ complex test: people who have a score of 24 or less on moca considered to have objective impairment. 2 groups: whether or not 24 week exercise program would improve executive function in ppl with mild cognitive impairment and cognitive impairment. Fast twitch, fatiguable (ff) [fast motor unit: characterized by highest conduction velocity, 100 m/s, largest alpha motor neuron in diameter, innervates fast twitch muscle bres, fatigue very easily, ii. Fast twitch, fatigue resistant (fr: characterized by medium conduction velocity, 60 m/s, medium bre diameter, innervates fast and slow twitch muscle bres, iii. Marathoner - 20% fast and 80% slow motor units: iii.
