| Research purpose: Using muscle state monitoring equipment,human joint measuring ruler and heart rate testing equipment to conduct marathon event of 12 male athletes in Jiangsu Province before exercise,immediately after exercise and 1 hour after exercise(relaxation activities are arranged within 10 minutes after exercise),The muscle state data collected 6hours after exercise,compared the effects of different recovery methods on skeletal muscle fatigue recovery,and provided a theoretical basis for the selection of fatigue recovery methods after marathon exercise.Research method: 12 male marathon runners respectively performed eight different muscle relaxation programs after 20 km running,including stretching relaxation,foam roller relaxation,antagonistic muscle training relaxation,three groups of the above-mentioned two-by-two relaxation methods,The three methods are superimposed to relax and naturally recover the eight groups of the control group.The Myoton PRO muscle state monitor,joint angle measuring ruler and FIRSTBEAT heart rate monitor were used to record the muscle tension,muscle stiffness,and muscle elasticity(muscle state)of the subjects in the quiet state in the morning,immediately after exercise,1h after exercise and 6h after exercise.The indicators were used to test the internal oblique femoris,lateral femoris,intermediate femoris and rectus femoris),joint range of motion,and heart rate.Research results:(1)The muscle tension values(internal oblique femoris,lateral femoris,intermediate femoris,and rectus femoris)were not significantly different between the groups at rest and immediately after exercise(P>0.05),seven relaxation interventions The schemes all caused a significant decrease in muscle tension 1h after exercise,and the data of part of the superimposed use group was significantly lower than that of the control group(P<0.05).The muscle tension of the internal oblique muscle at 1h after exercise has extremely significant difference between the superimposed use group and the control group(P<0.01),and the single relaxation application group and the control group have extremely significant differences with the three relaxation application groups at 6h after exercise(P<0.01);The muscle tension of lateral femoris muscle is significantly different between the superimposed use group and the control group at 1h after exercise(P<0.05),and there is a significant difference between the control group and the three relaxation groups at 6h after exercise.(P<0.05);The muscle tension of the intermediary femoris and rectus femoris muscles was significantly different between the control group and the three relaxation groups at 6h after exercise(P<0.05).(2)The muscle stiffness values(internal oblique femoris,lateral femoris,intermediate femoris,and rectus femoris)were not significantly different between the groups in a quiet state and immediately after exercise(P>0.05),and all seven relaxation intervention programs caused Muscle stiffness decreased significantly after 1 hour of exercise.The hardness of the internal oblique muscles was extremely significantly different from the control group in each experimental group at 1h after exercise(P<0.01),and there were extremely significant differences between the three relaxation and superimposed application groups and the control group at 6h after exercise(P<0.01);The hardness of the lateral femoris muscle is significantly different between the two relaxation methods superimposed use group and the control group 1h after exercise(P<0.05),and the three relaxation factors superimposed use group and the control group have extremely significant differences(P<0.01));Intermediate femoris hardness at 1h after exercise,the three relaxation factors superimposed use group and the control group have extremely significant differences(P<0.01),6h after exercise,the three relaxation factors superimposed use group and the control group have significant differences Difference(P<0.05);the stiffness of the rectus femoris muscle is significantly different from the control group in the foam roller +antagonist training group and the three relaxation superimposed use groups at 1h after exercise(P<0.05),and the superimposed relaxation is superimposed at 6h after exercise The groups were significantly different from the control group(P<0.05).(3)The logarithmic attenuation values of muscle amplitude(internal oblique femoris,lateral femoris,intermedius femoris,and rectus femoris)were not significantly different between the groups at rest and immediately after exercise(P>0.05).The logarithmic attenuation value of the amplitude of the internal oblique muscle is extremely significant difference between the three relaxation and superimposed application groups and the control group at 1 hour after exercise(P<0.01),and there is a significant difference between the single factor relaxation group and the three relaxation and superimposition groups(P<0.05).At 6h after exercise,the three relaxation superimposed groups have extremely significant differences from the control group(P<0.01);the logarithmic attenuation value of lateral femoral muscle amplitude is 1h after exercise in the three relaxation superimposed groups There is an extremely significant difference from the control group(P<0.01);the logarithmic attenuation value of the midfemoris muscle amplitude is extremely significant between the three relaxation and superimposed application groups and the control group at 1h after exercise(P<0.01),the stretching group And the antagonist training group was significantly different from the three superimposed relaxation groups(P<0.05).At 6h after exercise,the three superimposed relaxation groups were significantly different from the control group(P<0.05).(4)There was no significant difference in the supplementary angle of joint range of motion between the groups at rest and immediately after exercise(P>0.05).1h after exercise,the control group has extremely significant differences from the rest of the groups(P<0.01),and the three relaxation and superimposed application groups have extremely significant differences with the other groups(P<0.01);at 6h after exercise,the control group There are extremely significant differences from the other groups(P<0.01).There are extremely significant differences between the single-factor relaxation group and the three relaxation application groups(P<0.01).Except for the stretching group,the foam roller relaxation group is The remaining groups have extremely significant differences.(5)There was no significant difference in heart rate between groups during the experiment(P>0.05).Research conclusions:(1)In this experiment,a single relaxation method can achieve the purpose of promoting the recovery of skeletal muscle fatigue,but the superposition effect of two relaxation methods is better,and the superposition effect of three relaxation methods is the best.(2)Stretching and relaxation have a better short-term effect on reducing skeletal muscle tension and increasing muscle elasticity.Foam roller relaxation has a better long-term effect on reducing skeletal muscle tension and increasing muscle elasticity.When used in combination,the combination of stretching and relaxation has a better short-term effect on reducing skeletal muscle tension and increasing muscle elasticity,and the combination of foam roller relaxation has a better long-term effect on reducing skeletal muscle tension and increasing muscle elasticity.Three types of relaxation The superimposed use of methods has the best effect on reducing skeletal muscle tension and increasing muscle elasticity.(3)Foam roller relaxation has a better effect on reducing muscle stiffness after exercise than the other two groups of relaxation methods used alone.(4)The effect of stretching and relaxation on increasing the range of joint mobility is better than that of the other two groups of relaxation methods used alone.(5)Each relaxation mode has no significant effect on the recovery of heart rate. |
