Abstract
Objective:To evaluate the effects of exercise training at the maximal fat oxidation(FATmax)intensity on physique and cardiovascular function in the obese elderly.Method:Thirty-three obese elderly people(sixteen males,seventeen females and aged 60-70)were recruited as subjects for the study.The FATmax was identified through a graded exercise test for each subject,and a corresponding intensity was applied to design the individualized exercise program for them.Exercise training program lasted 12 weeks.BMI,WHR,vital capacity,grip strength,choice reaction time,sit and reach,the dynamic balance,blood pressure,EF,RPP,AI,VO_2 max,TG,TC,HDL-C and LDL-C were measured both pre and post the exercise training program.Result:1)The obese old males showed an average FATmax Rate of 0.44±0.14g/min and with a running speed of 4.13±0.80km/h at the moment.Compared with values obtained pre exercise program,BMI,WHR,abdominal fat percentage,visceral fat level,grip strength,AI,VO_2 max,EF,TG,HDL-C and LDL-C of the males presented significant improvements(P<0.05)post exercise program.2)The obese old females showed an average FATmax rate of 0.32±0.11g/min and with a running speed of 3.30±0.67km/h at the moment.Compared with values obtained pre exercise program,BMI,WHR,abdominal fat percentage,grip strength,SBP,AI,VO_2 max,RPP difference,cardiac output,EF,TG,HDL-C and LDL-C of the females presented significant improvements(P<0.05)post exercise program.Conclusion:Physique and cardiovascular function of the obese elderly improved significantly through a 12-week FATmax exercise based training program.
