Engaging in physical activity will help Engaging in physical activity will help lower the risk of getting many diseases, lower the risk of getting many diseases, and researchers are trying to eliminate and researchers are trying to eliminate obesity in young adultsobesity in young adults

Students should be doing about 30 Students should be doing about 30 minutes of moderate exercise to raise the minutes of moderate exercise to raise the heart rate heart rate

Purpose of studyPurpose of study

To determine if playing DDR is a correct To determine if playing DDR is a correct way of replacing physical activity such as way of replacing physical activity such as walking outsidewalking outside

To determine if experienced players burn To determine if experienced players burn more calories than inexperienced playersmore calories than inexperienced players

For students to get more physical activity For students to get more physical activity to minimize obesity and diseases to minimize obesity and diseases

MethodsMethods

Nineteen male students volunteeredNineteen male students volunteered 12 of the males were experienced (level 12 of the males were experienced (level

4) and 7 were not experienced (level 1-2)4) and 7 were not experienced (level 1-2) Males had to be non smokers and free Males had to be non smokers and free

from medical conditionsfrom medical conditions Each male had to complete 2 laboratory Each male had to complete 2 laboratory

consisting of a treadmill test and a session consisting of a treadmill test and a session of DDRof DDR

Methods (Continued)Methods (Continued) Before starting their sessions, they had to Before starting their sessions, they had to

rest for 15 minutesrest for 15 minutes The researchers recorded resting oxygen The researchers recorded resting oxygen

consumption (VO2), respiratory exchange consumption (VO2), respiratory exchange rate (RER), and heart rate (HR)rate (RER), and heart rate (HR)

Each participant was asked to refrain from Each participant was asked to refrain from eating 2 hours before and to avoid heavy eating 2 hours before and to avoid heavy exercise 24 hours before and no 48 hours exercise 24 hours before and no 48 hours beforebefore

Methods (Continued) Methods (Continued) During their session they wore shorts, t-During their session they wore shorts, t-

shirts, and athletic shoes to avoid changes in shirts, and athletic shoes to avoid changes in metabolic responsesmetabolic responses

They collected their still heart rate, walking They collected their still heart rate, walking at a self pace for 5 minutes, then increasing at a self pace for 5 minutes, then increasing it every 2 minutes until they were joggingit every 2 minutes until they were jogging

Then their heart rate the 30 minutes they Then their heart rate the 30 minutes they were playing DDRwere playing DDR

They collected how long it took each one to They collected how long it took each one to reach the 150 kcal lossreach the 150 kcal loss

FindingsFindings Due to this study the researchers were able Due to this study the researchers were able

to determine an estimate for the exercise to determine an estimate for the exercise intensity for experienced and for intensity for experienced and for inexperienced participantsinexperienced participants

Tell the differences between the groups by Tell the differences between the groups by doing repeated measures of the datadoing repeated measures of the data

The experienced players were younger than The experienced players were younger than the inexperienced players, but similar height, the inexperienced players, but similar height, etc. etc.

Findings (Continued) Findings (Continued)

No significant differences were seen in the No significant differences were seen in the metabolic rates in every malemetabolic rates in every male

The experienced players had a higher The experienced players had a higher average on all cardiovascular variablesaverage on all cardiovascular variables

The experienced players were able to The experienced players were able to achieve the 150 kcal where as the achieve the 150 kcal where as the inexperienced were not able under the 150 inexperienced were not able under the 150 kcalkcal

Discussion of FindingsDiscussion of Findings Energy expenditureEnergy expenditure during 30 minutes of during 30 minutes of

upper body exercise there is less upper body exercise there is less physically interactive video gaming going physically interactive video gaming going on then generated with the treadmill on then generated with the treadmill walkingwalking

Although that occurred all the participants Although that occurred all the participants enjoying playing DDR than the treadmillenjoying playing DDR than the treadmill

Playing at higher levels of DDR will allows Playing at higher levels of DDR will allows you to reach the 150 kcal needed dailyyou to reach the 150 kcal needed daily

Discussion of findings (Continued) Discussion of findings (Continued)

Body weight did not affect how quickly the Body weight did not affect how quickly the calories were lostcalories were lost

Experienced players are able to lose more Experienced players are able to lose more calories because they use their body more calories because they use their body more than the inexperienced than the inexperienced

The researchers also believed that the The researchers also believed that the experienced may have felt more relaxed experienced may have felt more relaxed playing then inexperienced playing then inexperienced

Discussion of Findings (Continued)Discussion of Findings (Continued)

The researches realized that increased concentration may increase playing time that would help increase energy expenditure

Limitation of the StudyLimitation of the Study This test is limited because it was only This test is limited because it was only

given to male college studentsgiven to male college students All the students attended the same All the students attended the same

college, they were not collected from college, they were not collected from different onesdifferent ones

The researchers used the cross-sectional The researchers used the cross-sectional approach to determine the influence that approach to determine the influence that playing experience would have on energy playing experience would have on energy expenditure during physically interactive expenditure during physically interactive video gamesvideo games

Limitations of the Study Limitations of the Study (Continued)(Continued)

The researchers only used one game to The researchers only used one game to determine if 150 kcal’s could be lost, and determine if 150 kcal’s could be lost, and the game was focused on lower body the game was focused on lower body movement movement

Suggestion for Future Research Suggestion for Future Research

They should get a larger group of people, They should get a larger group of people, and include woman and childrenand include woman and children

The researchers should also include other The researchers should also include other games that include physical activitygames that include physical activity

They should promote playing DDR so They should promote playing DDR so more people play and reach the amount of more people play and reach the amount of kcal's they should be losing everydaykcal's they should be losing everyday

Suggestion for Future Research Suggestion for Future Research (Continued)(Continued)

In future studies they should also include In future studies they should also include body composition rather than BMI to see if body composition rather than BMI to see if you lose body fat as wellyou lose body fat as well

Conclusions Conclusions Participants that had more experience Participants that had more experience

playing DDR did better than the people playing DDR did better than the people who did not have experience who did not have experience

The experienced players were able to The experienced players were able to reach the recommended loss of kcal’s reach the recommended loss of kcal’s unlike the inexperiencedunlike the inexperienced

DDR may be a way that many people will DDR may be a way that many people will begin exercising rather than going for a begin exercising rather than going for a walkwalk

Conclusions (Continued)Conclusions (Continued)

Playing games like DDR may reduce Playing games like DDR may reduce diseases that are caused by obesity or diseases that are caused by obesity or other risksother risks

Playing DDR is more enjoyable for many Playing DDR is more enjoyable for many people and may motivate them to become people and may motivate them to become more activemore active
