Brisk Walking Effect Assessment For 40-49 Years Old Adults In China

With the development of economy, individual's lifestyle changes a lot. Chronic disease incidence increases year by year. Long-term research has made it clear that every week 3-5 times, more than 30 minutes per time of moderate-intensity physical activity is benefit to health. But the existing assessment manuals don't contain of the biochemistry indicators and they are not comprehensive enough.Objectives:To form the exercise effect assessment system for 40-49 adults on brisk. This assessment will provide effective evaluation system for brisk intervention programs.And provides a constructing model for the formation of all ages and other types of exercise effect assessment system.Methods: We consulted articles on medline, EBSCOhost and PROquest databases by the keywords physical activity, physical fitness, assessment, evaluate, etc. We also recruited Volunteers to take part in the intervention project.Results:1) Establish the brisk walking effect assessment system for 40-49 adults. Choosing cardiorespiratory Fitness index, morphological index, physical fitness indexes, blood biochemical indicators and the WHOQOL-BREF. The weighting of each indexes is 22.9%, 20%,20%,19.5% and 17.6%, respectively.2) Ascertain each indicators and the weighting of the 5 indexes by factor analysis. Male:SBPrest, relative V02max, WC, bone strength index, push-ups, TC, HDL-C, hsCRP, WHOQOL-BREF. Female:SBPrest, relative V02max, body fat percentage, bone strength index, sit-ups, TC, TG, hsCRP, WHOQOL-BREF.3) Ascertain evaluation standards for the exercise effect assessment system for 40-49 adults. Single indicator takes five score method. Comprehensive evaluation takes 4 class rank method.4) 23 subjects completed intervention plans. Significant differences indicator:men, SBPrest, WC, TG; Female, body fat percentage, TC, TG.5) The indicators between the long-term exercising adults and sedentary adults statistically significant differences.Male:HRrest, relative VO2max, vital capacity, WC, WHR, body fat percentage, BMI, sit-and-reach, HDL-C; Female:HRrest, relative VO2max, vital capacity, steps index, WHR, BMI, bone strength index, grip, back force, sit-ups succession, sit-and-reach, TC, TG, HDL-C, hsCRP, blood sugar. These indicators directly support long-term aerobic exercise health effects.Conclusion:In this rereach we found that, active lifestyle people at 40-49 years old has significant lower risk factors for chronic disease than the sedentary ones, and have higher level of fitness. after 12 weeks brisk walking intervention, the sedentary subjects has significantly improved their fitness by body composition and TC, TG, etc, which implied the brisk walking intervention has decreased the risk foctors on chronic diseas. and by this exercise effect assessment could clearly evaluate the effectivness of the intervention plan on the risk factors of 40-49 years old adults.
