By means of literature, mathematical statistics and comparative analysis we made a case study of the test results of the physical health of undergraduate students from 2016 to 2018 at Wuyi University. We statistically analyzed the results of 7 tests on three indicators, namely, the body shape index (height and weight), body function index (vital capacity), physical quality index (speed test of 50 meters running, endurance test of 1000 meters for boys and 800 meters for girls, sitting forward bending test, strength test of standing long jump, test of one minute pull-up for boys and test of one minute sit-ups for girls). The results showed that most of the indicators were decreasing compared with previous results: the proportion of obesity and overweight was increasing; vital capacity was decreasing; speed and endurance were decreasing; the overall suppleness and flexibility were decreasing; the standing long jump showed an inverted U shape and muscle strength showed an upward trend; and the general grading of the test results was up to standard.
