8주간의 Schizandra chinensis의 복용이 운동선수의 체력요인변화에 미치는 영향

Abstract

This study was undertaken to examine the effect of Schizandra chinensis on the physical fitness in athlete. The sample group consists of a total 22 female soccer players who are working in Kyung Hee University. The group was divided into two groups with 12 and 10 persons respectively; The experimental group and control one were given a 7g of Schizandra chinensis and a 4g of placebo three times per day after the meal for the period of 4 weeks. The effect of Schizandra chinensis was measured in terms of their back strength, arm strength, leg strength, power, agility, flexibility to evaluate the change in physical fitness. The first measurement was carried out before drug administration and the second one was done after drug administration. The results are as follows ; 1) As for the record of the back strength, it was incresed from 106.59kg before the experiment to 116.14kg after 4 weeks in the experimental group and increased from 109.45kg before the experiment to 114.00kg after 4 weeks in the control group. 2) As for the record of the arm flexion strength, it was increased from 20.70kg before the experiment to and 23.09kg after 4 weeks in the experimental group and increased from and 18.10kg before the experiment to and 20.67kg after 4 weeks in the control group. 3) As for the record of the arm extension strength, it was significantly increased from 16.00kg before the experiment to 21.71kg after 4 weeks in the experimental group and significantly increaced from 12.90kg before the experiment to 20.88kg after 4 weeks in control group. 4) As for the record of the leg flexion strength, it was increased form 22.40kg before the experiment to 23.82kg after 4 weeks in experimental group and increased from 18.50kg before the experiment to 20.67kg after 4 weeks in control group. 5) As for the record of the leg extension strength, it was significantly increased from 51.20kg before the experiment to 59.18kg after 4 weeks in experimental group. As for the record of the leg extension strength, it was reduced from 44.00kg before the experiment to 40.67kg after 4 weeks in control group. It`s in experimental group was significantly increased after 4 weeks compared to control group. 6) As for the record of the power, it was significantly increased from 44.00cm before the experiment to 48.82cm after 4 weeks in experimental group while reduced from 47.60cm before the experiment to 45.66cm after 4 weeks in control group. 7) As for the record of the agility, it was significantly increased from 17.50 frequency before the experiment to 19.27 frequency after 4 weeks in experimental group and increased from 15.00 frequency before the experiment to 15.77 frequency after 4 weeks in control group. Agility in experiment group was significantly increased after 4 weeks compared to control group. 8) As for the record of the flexibility, it was significantly increased from 27.60cm before the experiment to 28.45 after 4 weeks in experimental group and increased from 24.75cm before the experiment to 26.22cm after 4 weeks in control group.
