[0064] Example 1-3, Comparative Example 1-4: Each group was gavaged with the sports endurance enhancing food formula prepared by the corresponding group once a day, 2 g / kg each time, for four consecutive weeks;

[0065] Blank group: The mice were gavaged with the same dose of saline during the corresponding time period, and were free to drink water and eat during the rest of the time.

[0066] The mice were weighed before, during (two weeks after intragastric administration), and at the end of the experiment (four weeks after intragastric administration).

[0067] 1.2 Exhaustive swimming test method

[0068] 30 minutes after the last administration, the mice in the blank group and Example 1-3 and Comparative Example 1-4 groups were subjected to an exhaustive swimming test. Each mouse was loaded with 5% of its body weight and swam in a water tank at a temperature of 25±1°C and a depth of 30 cm. The exhaustive swimming time was recorded from the start of swimming to the time when the mouse sank under water and could not float up for 10 seconds.

[0069] 1.3 Experimental methods for the effects of different formulas on serum urea nitrogen and liver glycogen after exercise

[0070] 30 minutes after the last administration, the mice in the blank group and Example 1-3 and Comparative Example 1-4 groups swam in a water tank at 30±1° C. without weight for 90 minutes, and then rested for 60 minutes, and then the levels of serum urea nitrogen and liver glycogen were measured.

[0072] 30 minutes after the last administration, the mice in the blank group and Example 1-3 and Comparative Example 1-4 groups swam without weight in a water tank at 30±1°C for 10 minutes, then rested for 20 minutes, and the blood lactate levels were measured before swimming, just after swimming, and after resting for 20 minutes.

[0073] 1.5 Results and Analysis

[0074] (1) The effects of the food composition on the body weight of mice are shown in Table 1 below.

[0075] Table 1

[0076]

[0077] (2) The results of exhaustive swimming time and biochemical indicators such as serum urea nitrogen and liver glycogen are shown in Table 2.

[0079]

[0080]

[0081] Note: In the same column, * Compared with the blank group, P<0.05; # compared with Example 1, P<0.05.

[0082] (3) The results of the biochemical index blood lactate levels of mice before and after swimming are shown in Table 3.

[0083] Table 3

[0084]

[0085] Note: In the same column, * Compared with the blank group, P<0.05; # compared with Example 1, P<0.05.

[0086] Result analysis: Compared with the blank group, the mice gavaged with the food composition of the present invention in Examples 1-3 had significantly longer exhaustive swimming time. After strenuous exercise, the decrease in serum urea nitrogen content and the increase in liver glycogen content were significantly slowed down. After a short exercise, the increase in blood lactate slowed down, and after rest, the metabolism of blood lactate was enhanced. It can be seen that the food composition of the present invention can significantly improve the body's exercise endurance.
