Abstract:
Objective:To design a set of anti-G physical fitness training program to improve strength tolerance, and further to investigate the effects of anti-G physical fitness training.Methods:According to requirement of the fighter pilots’ anti-G physical fitness on practical training for actual combat, a set of anti-G physical fitness training program was designed. The same expiratory manner as HP maneuver was applied in every item of the training. The training program included barbell squat training, dead lift training, bench press training, tilt board crunch, seated kick, and respiratory muscle training. Eight healthy male subjects volunteered for the study were trained according to the training program for 12 weeks. The strength training was undertaken on 3 separate days per week. Four intensities of the training were performed along with the medium-highest-medium-higher or medium-higher-highest-higher modes. The indicators related to the level of anti-G physical fitness of subjects before and after training were tested. Paired test was performed for the statistical assessment of the anti-G physical fitness level with SPSS software.Results:Compared with those before training, 1 repetition maximum (1 RM) and 10 RM of barbell squat, dead lift, and bench press after training were significantly increased respectively( t=6.382-16.767, P<0.01). 10 RM of the 3 items increased respectively 51.5%, 27.6%, and 46.0%. 1 RM of the three items increased respectively 57.7%, 34.0%, and 45.2%. The number of leg-raising times of tilt board crunch significantly increased ( t=7.508, P<0.01) ,which increased 69.9% under double load of the legs after training. When the tolerance time of abdominal muscle was equivalent, the load of the legs after training was double load before training. Strength tolerance of pedal force of lower limbs significantly increased 188.7% averagely( t=8.213, P<0.01) after training. Maximal expiratory pressure (MEP) and maximum inspiratory pressure (MIP) averagely increased 42.4% and 19.7% respectively ( t=7.361, 4.119, P<0.01) after training. Strength tolerance of respiratory muscle averagely increased 270.0% ( t=7.800, P<0.01) after training. Conclusions:The anti-G physical fitness training program can effectively improve the strength tolerance of the main muscle groups correlated to anti-G ability. The effect of the program on improving the level of the subjects’ anti-G physical fitness is obvious, which establishes the basis of applying the program for verification in fighter pilots.
