Roller Skating Movement On The Effect Of Body Function In The Elderly In The 50 To 60 Years Old

This thesis chooses the middle-aged and the old, who have participated in rollerskating in parks and squares such as Baoding Botanical Garden and the MilitaryAcademy Plaza as the research subjects, adopting the document-data method,experimental method, survey method, interview method and statistical approach totake study on the indices related to those skaters’ cardiovascular system, respiratorysystem, nervous system, and the athletic ability. The main purposes are to analyze theeffects of roller skating on the physical function of the50-to-60-year-old, and then toselect the physical fitness activities for the elderly, and provide reference for thestudies on the roller skating of this group and the effective popularization of it.Results of the Study:The changes of major indices of subjects after the roller skating exercises are asfollows:(1) Cardiovascular function indices:Heart rate: the Basal Heart Rate changes from76.43±8.36to70.47±7.54beats/min, which has a very significant difference (P <0.01); the heart rate in exerciseschanges from130.77±4.45to115.40±3.79beats/min, which has a very significantdifference (P <0.01); the immediate heart rate changes from127.10±4.06to116.10±BPM4.11/min, which has a very significant difference (P <0.01); and therestoration of heart rate at5-10minutes after exercises changes from99.23±7.86to79.20±8.66beats/min, which also has a very significant difference (P <0.01).Blood pressure: early morning blood pressure: the diastolic pressure changesfrom83.63±4.35mmhg to76.80±3.51mmhg, and systolic pressure from127.40±6.31mmhg to118.23±5.49mmhg, both of which have a very significant difference (P<0.01); the immediate blood pressure after exercise: diastolic pressure changes from82.90±4.34mmhg to75.06±3.47mmhg, systolic pressure from138.93±3.02mmhgto141.83±2.15mmhg, both of which have a very significant difference (P <0.01);the blood pressure at30minutes after exercise: the diastolic pressure changes from82.90±4.37mmhg to75±3.34mmhg, systolic pressure from125.07±6.57mmhg to 113.80±4.91mmhg, both of which have a very significant difference (P＜0.01).The cardio function index: the index of heart function changes from161.42±12.88to137.44±10.80, which has a very significant difference (P <0.01).(2) Respiratory system function indices:Spirometry: vital capacity changes from3154.6±706.99to3630.1±636.47,which has a very significant difference (P <0.01).Pulmonary ventilation: the pulmonary ventilation volume changes from4573.80±1302.79to4933.70±1266.75, which has a very significant difference (P <0.01).(1,2) Cardio-pulmonary function indices (adopting the maximal oxygen uptake):Maximal oxygen uptake varies from2.52±0.44L/min to2.66±0.45L/min,which has a very significant difference (P <0.01).(3) Nervous system function indices (adopting the reaction time):Light reaction time changes from311.39±39.94to292.90±40.40MS, whichhas a very significant difference (P <0.01); nelson bar reaction time changes from200.65±10.42to191.65±9.34MS, which has a very significant difference (P <0.01); whistle reaction time changes from280.58±24.84to258.18±24.21MS, witha very significant difference (P <0.01).(4) Athletic ability indices:Blind stance on a single foot: one-legged standing time changes from10.66±3.42to18.74±5.74seconds, which has a very significant difference (P <0.01).Sliding ability on single-legged support: the sliding distance changes from4.77±1.54to15.31±6.88meters, which has a very significant difference (P <0.01).Coordination ability: cross-legged sliding ability: the frequency of slidingchanges from3.87±3.04to22.90±13.24, with a very significant difference (P <0.01).Variation of shape and weight: the weight changes from69.40±8.14kg to67.88±7.44kg, which is not a significant difference (P=0.062, P>0.05); thighcircumference changes from51.2±4.33cm to51.08±4.25cm, which is not asignificant difference (P=0.326, P>0.05); waist circumference changes from87.23±6.16cm to84.98±4.88cm, which has a very significant difference (P=0.001, P < 0.01).Results of the questionnaire: after6months of roller skating, there are74%people feeling energetic and pleasant, and becoming calmer and less likely to losetemper. The elderly who are less healthy decrease from the previous15.5%to7%.And those with good appetite increase by14%while people with bad appetite reduceby8%. Although there is no significant difference after the exercises, it reflects thatthe phenomena of the anorexia, bloating, constipation significantly decline.Conclusion:Firstly, after24weeks of exercises of roller skating, there has been a great andpositive improvement in the indices of cardiovascular system, respiratory system,nervous system, and athletic ability of the subjects (the elderly skaters in BaodingCity).Secondly, the questionnaires reflect that after24-week roller skating, thesubjects’ mood and sleep get obviously improved. So it is evident that roller skatingcan positively help prevent neurasthenia, neurological disorders, insomnia, andimprove the digestive system of the elderly, which is proved by the reduction ofanorexia, bloating, constipation.
