Identifying multiple "MAX" values?

So I have a force plate that measures the force in Newtons at 1500 Hz. If I have someone jump up and down for 30 seconds we'll see a since wave with the center at body weight and the valleys during flight and peaks during the peak landing force. Suppose they jump 50 times in 30 seconds. That's a 45,000 data point array of numbers. Can you think of a way I can find the peak number per jump without manually scanning the array and putting it into a new array of 50 data points?? It really can't be based on the timing because we may manipulate the rhythmic timing of the jumps.
