China Sport Science, launched in 1981, is the official publication of China Sport Science Society and hosted by China Sport Science Society. General Administration of Sport is its authorities concerned. Under the new background of sports development, the journal aims at publishing more high-level research results which reveals the development of sports science in China. More academically innovative and pratically significant papers are expected to inject new vitality into this influential and comprehensive sports academic journal.

Objective: To compare the energy metabolism characteristics in different modes of sprint speed endurance training. Methods: The blood lactate (BLA) and energy metabolism levels of 14 well-trained sprinters (age: (18.57 ± 2.56) years old, height: (181.00 ± 5.16) cm, weight: (68.00 ± 6.45) kg, training years: (6.35 ± 2.92) years, 200 m PB: (22.19 ± 1.06) s) in the four speed endurance training modes (i.e., HV-1, HV-2, HI-1 and HI-2) were obtained and analyzed with a portable blood lactate analyzer and a portable gas analyzer, respectively. The sprinters’ energy supply profiles in these four speed endurance training modes were calculated and compared according to their oxygen uptake (VO2) , BLA and the fast component of the excess post-exercise oxygen consumption (EPOC) . Results: The energy supply from the ATP-CP system in HV-1, HV-2, HI-1 and HI-2 modes were (217.35 ± 43.78) kJ, (206.15 ± 25.49) kJ, (117.10 ± 18.79) kJ and (120.31 ± 19.10) kJ, respectively. The energy supply form the glycolytic system in HV-1, HV-2, HI-1 and HI-2 modes were (77.13 ± 8.88) kJ, (99.74 ± 16.64)(81.75 ± 8.23) kJ and (95.47 ± 8.46) kJ, respectively. The energy supply from the aerobic system in HV-1, HV-2, HI-1 and HI-2 modes were (155.62 ± 27.16) kJ, (172.05 ± 37.12) kJ, (56.04 ± 14.17) kJ and (55.62 ± 15.52) kJ, respectively. Conclusion: Different speed endurance training modes have different energy metabolism characteristics, the grouping pattern was a key factor affecting the proportion of anaerobic glycolytic systems involved in energy supply, double-set modes (HV-2 and HI-2) were more effective than single-set modes (HV-1 and HI-1) in enhancing athletes’ speed endurance. The athletes were recommended to develop their speed endurance mainly by performing HV-2 mode during the general preparation phase, and the HI-2 mode can be used to develop their speed endurance during the special preparation phase.

The evaluation of rural sport governance is an important theoretical and practical problem. Based on the guidance of good governance, this paper constructed an evaluation index system of rural sport governance from three-dimensional perspectives, namely, governance input, governance process, and governance output, by using the methods of literature research, investigation and mathematical statistics and other methods, and referring to the evaluation theory and the social index theory. The index system constructed in this paper included three first-level indexes, 16 second-level indexes and 40 third-level indexes, which had been tested empirically in this paper. The empirical results showed that the level of rural sport governance was generally a ladder-like distribution in the eastern, central and western regions, but some of the third-level indexes did not show obviously ladder-like characteristics, and there were even a few indexes in an anti-ladder distribution. The results of comprehensive empirical research showed that the current rural sport governance should change the focus from paying attention to the hardware investment, such as venue and facilities, to the software investment, such as organization and propaganda work, and then combine hard and soft investment to promote the development of rural sport governance in the new period. In addition, although the government is the core force of rural sport governance, the social forces should not be neglected. Therefore, we should give full play to the positive role of social forces in rural sport governance, so as to form a pattern of good governance with multiple coexistences and combined efforts.
