RESUMEN
Objective To investigate the current situation of long-term care needs of the elderly with home-based disabil-ity in Beiliu City,and provide data support for the development of Internet plus care services in Beiliu City.Methods A ques-tionnaire survey method was used to design and distribute a survey questionnaire titled"Survey Questionnaire on Home Care Serv-ice Needs of Disabled Elderly People",to investigate the nursing service methods and home care needs of disabled elderly people in Beiliu City.Results Disabled elderly people mainly choose home-based nursing services,with a high demand for basic care,comfortable care,rehabilitation care,psychological care,and other aspects.Conclusion Home care is of great significance for improving the quality of life of disabled elderly people,and requires policy support such as medical insurance to promote the sup-ply of nursing services and meet the care needs of disabled elderly people.
RESUMEN
Objective To explore whether remote ischemic preconditioning(RIPC)can prolong the time of ultra-intense exercise(110%VO2max)by increasing the maximum cumulative oxygen deficit(MA-OD),and the specific ways of energy supply of the anaerobic metabolic system.Methods Twenty-four racquet athletes(22.2±2.0 years;174±9 cm;67.1±12.4 kg)completed three supramaximal intensi-ty tests on a treadmill at 110%VO2max intensity to exhaustion separated with Control,Placebo and RIPC interventions.RIPC was induced on the limbs on both sides(5×5 min alternating bilateral occlu-sion 220 and 60 mmHg for Placebo and RIPC interventions,respectively).Moreover,all groups under-went a fourth test with incremental load,and a fifth test with constant load at 40%,50%,60%,70%and 80%VO2max.Results The time to exhaustion and the MAOD of the RIPC group were both greater than those in the Placebo and Control groups(P<0.05).However,no significant differences were found in the average alternative maximal accumulated oxygen deficit(MAODALT),lactic anaerobic metabolism,alactic anaerobic metabolism and parameters of excess post-exercise oxygen consump-tion dynamic curve of the three groups(P>0.05).Meanwhile,in the RIPC group,the average MAOD was significantly higher than MAODALT(P<0.05).Pearson correlation analysis showed a significant rela-tionship between the improvement of MAOD and an increase in exhaustion time after RIPC interven-tion.Conclusion RIPC can improve supramaximal exercise performance of racquet athletes by enhanc-ing their MAOD,and the enhancement of glycolysis energy supply and lactic acid elimination is a po-tential intermediary of the improvement of sports performance.
