in ability of a muscle to generate force. It can be a result of strenuous exercise but unusual fatigue may be caused by interference with the different stages of muscle contraction. There are two main causes of muscle fatigue‚ nervous fatigue and metabolic fatigue. Nervous Fatigue Nervous fatigue is the decline in the ability of a nerve to sustain a signal resulting in innervation of the muscle. The muscle’s ability to generate force is most strongly limited by nerve’s ability to sustain a high-frequency

Normal Distribution:- A continuous random variable X is a normal distribution with the parameters mean and variance then the probability function can be written as f(x) = - < x < ‚ - < μ < ‚ σ > 0. When σ2 = 1‚ μ = 0 is called as standard normal. Normal distribution problems and solutions – Formulas: X < μ = 0.5 – Z X > μ = 0.5 + Z X = μ = 0.5 where‚ μ = mean σ = standard deviation X = normal random variable Normal Distribution Problems and Solutions – Example
