[Effects of low intensity resistance training of blood flow restriction with different occlusion pressure on lower limb muscle and cardiopulmonary function of college students].

The study compared the effects of low intensity resistance training with blood flow restriction (BFR) with different occlusion pressure on lower limb muscle and cardiopulmonary function. Twenty-seven college students were randomly divided into three groups by different occlusion pressure: 0 mmHg (group C), 120 mmHg (group L) and 180 mmHg (group H). Before and after training (3 times a week for 12 weeks) with an inflatable cuff (20% 1RM, half squat), the muscle thickness(MTH)of rectus femoris and medius femoris, relative peak knee extensor moment(rM), peak power(P), relative maximal oxygen uptake(rVOmax), stroke volume(SV), cardiac output(CO), ejection fraction(EF) and other indicators were measured for all subjects.

[The effects of 10-week core strength training on the body balance in the middle-aged men].

Objective: To observe the effects of core strength training on the body balance of middle-aged men, which could provide evidence for improving the body balance and reducing the risk of falls in the middle-aged men.

Methods: Sixteen 50~60 years old men were randomly divided into experimental group (core strength training, =8) and control group(=8). Intermittent core strength trainings were used for dynamic and static training, push-pull training and unarmed lower limb strength training by suspension ropes and yoga mat.

[The effects of endurance training on IL-18 and IL-10 in athero-genic ApoE mice].

Objective: To investigate the effects of endurance training on interleukin-18(IL-18) and IL-10 in atherogenice apolipoprotein E gene knockout(ApoE)mice and explore its possible mechanism preventing atherosclerosis occurrence.

Methods: Twenty male ApoE mice (age:8 weeks) were randomly divided into atherosclerosis(AS)model group(AC) and exercise group(AE) and chose male C57BL/6J mice (age:8 weeks) as control group (CC). After 12 weeks, the aortic trunk closed heart was prepared for frozen section, which were used to observe the changes of plaque area and pathology.

[The effects of high fat diet and endurance exercise on the aorta wall structure of experimental animal].

Objective: Based on high fat diet induced the model of atherosclerosis (AS) in C57BL/6J mice, authors studied the effect of endurance exercise on the atherosclerostic formation.

Methods: Forty eight 8-week-old C57BL/6J mice were divided into four groups randomly (n=12): control (group N), 12-week atherosclerosis model group(group H), 12-week atherosclerosis model plus 11-week treadmill training group (group H + E) and 22-week atherosclerosis model group (group HS). Then, we observed the effects of endurance exercise on the ultra structure of aorta by electron microscope.
