Comparisons Of Physical Activity And Energy Consumption In PE-Major And Non PE-Major College Students

Objective:The purpose of this study is through surveying the Physical Activity and EnergyConsumption of PE-Major and Non PE-Major college students to analyze thecharacteristics of their school days and weekend’s physical activity levels and energyconsumption, to compare their differences, and to explore the impact of physical educationcourse to the Physical Activity level and Energy Consumption of college students.Methods:The study recruited180volunteers from PE-Major and Non PE-Major college students ofCapital University of Physical Education and Sports. We record the volunteer’s height,weight, sex, date of birth, and other basic information. And then using the RT3accelerometer to record their physical activity levels and energy consumption. Thevolunteers were asked to wear the device continuously seven days (including five schooldays and two weekend days). The screening criteria of valid data is that the subjects Atleast wear8hours effectively in a day and wear two school days and one weekend day intotal. Using independent samples T test to compare differences between gender and major,using paired sample T test to compare differences between school days and weekend days.Results：In this study, there are86students providing a valid accelerometer data, including45(male19, female26) people from PE-Major and41(male21, female20) from NonPE-Major. Their average age was19.33±0.77years old and19.59±0.67years oldrespectively.1. PE-Major students’ daily meditation time were significantly lower than Non PE-Major(445.76±103.73min/d vs491.43±86.29min/d, P<0.05); the low-intensity physicalactivity time(LPA) and the high-intensity physical activity (MVPA) time of PE-Majorstudents were significantly higher than those of Non PE-Major (152.81±46.50min/d vs119.35±42.33min/d, P<0.05)(124.19±39.28min/d vs79.71±25.65min/d, P<0.05), andthey have the same energy consume trend; Both PE-Major and Non PE-Major malestudents daily MVPA time were significantly higher than female (149.07±33.82min/d vs106.01±32.83min/d,82.76±31.50min/d vs76.52±17.87min/d, P <0.05).2. PE-Major students’ school day LPA and MVPA were significantly higher than NonPE-Major, and they have the same energy consume trend;(166.05±54.90min/d vs133.45±50.49min/d, P <0.05),(147.17±43.92min/d vs100.53±29.46min/d, P<0.05), and they have the same energy consume trend;3. PE-Major students’ weekend meditation time were significantly lower than NonPE-Major (431.26±124.17min/d vs484.83±110.56min/d, P<0.05) were significantlylower than non-sports majors, but their LPA and MVPAwere significantly higher thanthose of Non PE-Major (141.23±63.42min/d vs105.24±50.15min/d, P<0.05),(102.67±44.50min/d vs58.90±35.54min/d, P <0.05), and they have the same energy consumetrend.4. PE-Major students’ school day LPA and MVPA were significantly higher than weekends,(166.05±54.90min/d vs141.23±63.42min/d, P<0.05),(147.17±43.92min/d vs102.67±44.50min/d, P <0.05); And non PE-Major students’ school day LPA and MVPA were alsosignificantly higher than weekends,(133.45±50.49min/d vs105.24±50.15min/d, P<0.05),(100.53±29.46min/d vs58.90±35.54min/d, P<0.05), and they also have the sameenergy consume trend.Conclusions:1. Both PE-Major and Non PE-Major students achieve the recommended amount (carriedover60min in high-intensity physical activity every day) physical activity whichFormulate by School of Medicine (IOM) for college students.2. Compared with Non PE-Major, PE-Major have lower sit-time,and longer physicalactivity time, and much more energy consumption.3. Both PE-Major and Non PE-Major students show a same characteristics: the physicalactivity and energy expenditure keep higher in school days than weekends, and boys arehigher than girls.4. Physical education courses have positive effect in promoting physical activity levels andenergy consumption of PE-Major and Non PE-Major college students.
