Aerobic Training And Cpet Knee Cruciate Ligament Reconstruction Applied Research In The Early Postoperative Rehabilitation

Purpose:This research intention to developed the effective programme of evaluated and maintained or improved cardiorespiratory adaptation of patients after reconstruction of cruciate ligaments of knee joint by CPET and the Upper extremity ergometry aerobic training during early rehabilitation (early4weeks).Method:41patients (with25athletes, ordinary people16)were divided into the control group and the training group respectively, then the athletes training group divided into continuous and intermittent group. Control groups exercised by general training prescription after operation, and training groups added aerobic training for4weeks. All subjects completed the CPET and serum VEGF, BFGF before and after4weeks of rehabilitation training.Results:1. Ordinary people1of control group diplayed significant reduction (p<0.05)of V02peak, V02peak/Kg, MET,02Plus. SV, RQ, VT, and Ca(a-v)02, while significant increase (p<0.05) of BR after4weeks training. And aerobic training groups showed increased markedly (p<0.05) of V02peak, V02peak/Kg, MET,02Plus, SV, Ca(a-v),02and VE, while significantly reduction of V02/WR.2. Athletes control group expressed significantly reduction of V02peak, V02peak/Kg, MET,02Plus, SV and Ca(a-v)02(p<0.05), and it is a very significant negative correlation between the initial V02pcak and the change of V02neak. At continuing training group diplayed02Plus significantly reduction only, while V02peak, V02peak/Kg, MET,02Plus, VE, VT and Ca(a-v)02are significantly increased (p<0.05) in the athletes interval training group. In continuing training group V02peak, V02peak/Kg, MET,02Plus and SV has decreased but were higher than those of the control group significantly reduced (p<0.05), and the interval training group showed significantly (p<0.05) increases.3. The serum VEGF, BFGFof Ordinary people and athletes training groups and VEGF of interval training group significantly increased after4weeks training.4. The increase of athietes V02peak, V02peak/Kg, MET,02Plus, SV, and Ca(a-v)02are significantly lower than the ordinary people (p<0.05) after aerobic training,Conclusion:1. Ordinary people is significantly reduced on cardio pulmonary adaptation after4weeks general aerobic training, while it is significant increase after added4weeks aerobic exercise.2. Athletes increased in weight and BMI after4weeks of general training, and cardio-pulmonary adaptation significantly reduced, and the drop of V02peak and initial V02peak showed highly negative correlation.3.It showed more significant improvement of cardio-respiratory adaptation after intermittent training than continuing training in athletes.4. After4weeks of aerobic training ordinary people serum VFGF, BFGF expression and athletes serum VHGF expression showed highly level, which indicates aerobic training played a positive role on repair tendons ligaments.
