Physical Fitness Test Method
The experiment mainly uses the physical fitness test method to test the physical quality indicators before and after the test subjects. the items of this test were selected according to the National Physical Health Standards for Students (2014 Revision), as shown in Table 1.

Experimental Content
This experiment was mainly modified in accordance with the books "Modern University Physical Education Tutorial", "Physical Training Theory and Practice" and "Physical Training", and under the guidance of the physical fitness teacher, Gao Di. The time of this experiment was. The experiment was 16 weeks, every 4 weeks for a total of 4 cycles. Training occurred once a week with mainly 90 minutes. The warm-up part before the training is 10 minutes, which is divided into 400 meters of warm-up running, freehand exercise and simple sports games. The training part is 75 minutes, and the relaxation activity is 5 minutes, including the upper and lower limb relaxation and whole-body muscle relaxation exercises. Specific training contents are shown in Table 2.  (2)

Results of the Subject Test Index after the Experiment
To further analyze the results of the physical reinforcement class, the results of the two groups were tested, and the test results are shown in Table 3.

Analysis of the Test Index Results of the Experimental Subjects after the Experiment
As shown in Table 3, after 16 weeks of physical intensive training, the 50 m timing running performance was 8.69 ± 1.04 and 50 m paired sample T-test of 50 m ± 1.00 showed the p-value of 0.000 (P <0.05), indicating that after 16 weeks of training, the performance was greatly improved and significantly different after the 50 m running training. Vertical long jump results were 193.70 ± 29.60 before training, 207.01 ± 31.62 after 16 weeks of training. The results of the paired sample of the two groups showed a p-value of 0.000 (P <0.05), indicating the significant improvement after training and the significant difference between the two groups. After 16 weeks of training before and after training, 13.22 ± 7.17 and 14.97 ± 6.35, a paired sample T test of the two groups showed a p-value of 0.000 (P <0.005), showing a significant difference in pre-training performance. The average score of the 800 m run before training was 4.64 ± 0.50 and 4.32 ± 0.44, and a paired sample T test for the two groups showed a p-value of 0.000 (P <0.05), thus indicating that the physical intensive training effect was very significant between the two groups. As shown in the chart above, the average 1000 m run was 4.47 ± 0.49 and 4.27 ± 0.45 after 16 weeks of physical intensive training, which shows a certain improvement in pre-training performance. The two groups of data were further subjected to a paired sample T-test, and the p-value was 0.000 (P <0.05), indicating that the results of the two groups were significantly different. With one-minute sit-ups of 29.60 ± 7.13 before training and 39.78 ± 8.89 after 16 weeks of training, data were a paired sample T test showing a p-value of 0.000 (P <0.05) with significant differences between the two groups. The pull-up average was 3.60 ± 3.55 and 5.39 ± 4.13 after 16 weeks of physical reinforcement class training, and the paired sample T test showed a pvalue of 0.000 (P <0.05), indicating a significant difference between the two groups.

Conclusion
(1) After 16 weeks of physical reinforcement training, the T test p-value of the last paired samples of the 7 physical test items showed a significant difference, indicating that the physical reinforcement class had a significant effect on the students who failed the physical test.
(2) Most students who failed the special physical training have reached more than 60 points, indicating that the physical class has played a positive effect, improving the physical quality is better than the regular physical education class.
(3) It can be concluded from the data that although both sit-ups and pull-ups are significantly improved, the growth of sit-ups is far high and pull-up. This can show that the more difficulty for boys requires more core forces.

Suggestions
(1) After 16 weeks of physical intensive training, it is found that it has a good effect in improving students 'physical quality and exercise methods. It is suggested to appropriately add physical intensive training to the usual physical education teaching of college students, so as to better develop students' speed and strength quality and optimize the physical fitness teaching effect.
(2) The amount of physical reinforcement training is large, so the training load can be reasonably adjusted according to the situation in the future training, which can increase the diversity of physical training and increase students' interest.
(3) Pull-up for boys in the future course training arrangement should be arranged more training time to strengthen the core strength training of the trunk and other related auxiliary exercises.
