Experimental Study On The Effect Of Swiss Ball Intervention On Lower Limb Muscle Strength Of Middle - Aged Women

Objective: Middle-aged women decline in muscle strengthincreases as the age of growth, leading to osteoporosis, balance, fall, leading to falls.This experiment research has Swiss ball intervention on middle-aged female lowerlimb muscle force of effects, on experiment group intervention before and aftermiddle-aged female of lower limb muscle force changes and experiment group andcontrolled group of test results for contrast and analysis, turn demonstration Swiss ballas fitness means, on middle-aged female of fitness value, for middle-aged femalefitness provides science pursuant to, while also for middle-aged female science forlower limb power exercises provides simple effective of movement prescription, andfor "Swiss ball as fitness means" of creating and the promotion provides theory.Methods: Nearby Chengdu Sports University raised body health, has exercisehabits, no metabolism sexual disease, no central nervous problem, no knee disordersand voluntary participate in and tie experiment measurement of by try who, throughhealth body suitable can institutions movement before sieve check questionnaire andPAR-Q questionnaire filter45(51.55±3.91) age above middle-aged female20name,which random filter experiment group10name, controlled group10name, first onexperiment group for Swiss ball intervention of pre-experiment, The participants ’subjective exercise intensity (RPE) as criteria for determining exercise intensity, oninitial creation of "Swiss ball fitness" modification of structure and movementbetween groups, form the final "Swiss ball fitness" exercise program. Yu weeklyMonday, and Wednesday, and Friday7:30points to8:30points in Chengdu Instituterehabilitation three floor for Shi long for60minutes of "Swiss ball fitness" movementintervention, for10week, experiment before and after in Chengdu Instituterehabilitation II floor respectively on by try who left leg for CON-TREX, speedmuscle force corner speed for60°/s and120°/s of test, meanwhile, on by try who leftleg unit four head muscle of unit inside muscle, and unit outside side muscle and unitstraight muscle for MEGA WIN ME600O eight channel (T8) collection and analysisof surface EMG.Results: Experiment before and after, experiment group knee, speed centrifugalmovement in the, corner speed60°/s territory knee flexor of conditions experimentgroup of by try who of peak torque, and relative peak torque, and total power and theunit straight muscle are has significantly sexual differences (P<0.05), experimentgroup by try who unit outside side muscle points muscle electric area (Area) andmuscle electric maximum value (Max) has very significantly sexual differences (P<0.01), and experiment group and controlled group compared to, peak torque hasvery significantly sexual differences (P<0.01); corner speed60°/s territory kneeextension of conditions experiment group peak torque, and relative peak torque, andunit straight muscle electric maximum value (Max) are no obviously differences(P>0.05), total power, and unit outside side muscle, and unit inside muscle and unitstraight muscle points muscle electric area (Area) and the unit inside muscle electricmaximum value (Max) has significantly sexual differences (P<0.05), unit outside sidemuscle electric maximum value (Max) has very significantly sexual differences(P<0.01), Experimental group and the control group compared with the relative peaktorque and total work has significant differences (P<0.05); Corner speed120°/sterritory knee flexor of conditions experiment group of peak torque has verysignificantly sexual differences (P<0.01), relative peak torque and total power are hassignificantly sexual differences (P<0.05), experiment group unit outside side muscleand unit inside muscle points muscle electric area (Area) and muscle electricmaximum value (Max) are has very significantly sexual differences (P<0.01), unitstraight muscle no obviously differences (P>0.05), The experimental group and thecontrol group compared with the peak torque and total work has significantdifferences (P<0.05), relative differences are significant peak torque (P<0.01); Cornerspeed120°/s territory under the condition of the knee extensor peak torque there arevery significant differences between the experimental group (P<0.01), relative peaktorque and total work has significant difference (P<0.05), vastus lateralis rectusfemoris and Vastus medialis muscle area (Area) and EMG Max (Max) were notsignificantly different (P>0.05), the experimental group and the control groupcompared with the relative peak torque and total work has significant difference(P<0.05).Conclusion:After10weeks of Swiss ball following the intervention ofmiddle-aged women in increasing muscle strength, effective. Long term Swiss ballstrength training can improve lower extremity muscle strength of middle-agedwomen.
