Research On The Effect Of Compound Training On The Lower Limb Rapid Strength Of Male Basketball Players In Ordinary Universitie

The scientific basis for compound training is the post activation and enhancement effect of muscles.It is set up to conduct heavy resistance strength training first,and then conduct rapid expansion and contraction compound training with no or light load similar to basketball technical movements,to achieve the goal of improving the maximum muscle strength and lower limb fast strength of athletes.In the experimental intervention on male basketball players from Tianjin Vocational and Technical Normal University,three groups were set up,which were experimental control group(single resistance training),experimental group Ⅰ(traditional composite training),and experimental group Ⅱ(composite training).The training plan content order of experimental group Ⅰ and experimental group Ⅱ was different.The experimental control group completed single resistance strength training;After completing a single resistance training content,experimental group Ⅰ underwent enhanced training designed based on selected biomechanical characteristics similar to those of basketball events;The exercise content of experimental group Ⅱ is the same as that of experimental group Ⅰ,but in a different order.Resistance training is conducted first,followed by alternately designed enhanced exercises.Through intervention,the intention is to explore the design and content of comprehensive training to achieve the effect of enhancing the rapid strength of the lower limbs of male basketball players.Test method: After an 8-week experimental intervention on the men’s basketball team of Tianjin Vocational and Technical Normal University,24 players were randomly divided into three groups: experimental control group(single resistance training),experimental group Ⅰ(traditional composite training),and experimental group Ⅱ(composite training).Relevant data indicators related to lower limb strength were tested using a dynamometer instrument,including: CMJ squat jump,SJ half squat jump,in-place double foot vertical jump Data collection was conducted on the average takeoff time,height,and explosive power index of the three-step layup run up single leg jump to reflect the differences in intervention.Through the use of relevant data software(SPSS23.0),reasonable statistical analysis was conducted on the experimental data,mainly to compare different situations within and between groups.(1)In the experiment of setting detection targets for jumping related actions,it can be found that most of the lower limb joint muscle groups of the experimental subjects are performing repetitive movements that complete the lengthening shortening cycle,which can better provide feedback on the lower limb fast strength of the subjects.The form of muscle contraction will be considered as a key factor in developing athletes’ rapid strength in their lower limbs.(2)After completing this short-term experiment,analysis can confirm that the training effect of compound training on experimental subjects is more prominent.Using expert interviews and literature methods,we selected test indicators to measure the rapid strength of men’s lower limbs as a test tool for this 8-week experiment.The experimental subjects were the experimental control group(single resistance training),the experimental group Ⅰ(traditional composite training),and the experimental group Ⅱ(composite training),a total of three groups.The intervention program included70% 1RM,80% 1RM,and 90% 1RM weight bearing squats as pre stimulation and rapid stretching composite training.Through comparative analysis of experimental data,experimental group Ⅰ(traditional composite training)and experimental group Ⅱ(composite training)had better data indicators than the control group(single resistance training).In the experiment,the three groups have good effects in developing the maximum strength of athletes’ lower limb muscles.(3)After analysis,it was found that the results of experimental group Ⅱ(composite training)were slightly better than those of experimental group Ⅰ(traditional composite training)due to the structural setting of training content in experimental intervention.
