Project Title: Achieving Maximum Oxygen Consumption By Effectively Working Out             

  1. Question or Problem being addressed
  • What effect does the type of workout have on heart rate and how can oxygen consumption be maximized? 
  1. Goals/Expected Outcomes/Hypotheses
  • Goals: Gather data from all 4 groups and identify the maximum oxygen consumption 
  • Hypothesis: The group that only runs will have the highest oxygen consumption, making it the most efficient workout. 
  • Expected Outcomes: The group that runs and bikes will have the highest oxygen consumption. The group that only lifts will have the least oxygen consumption. The group that performs all the workouts will have an efficient workout, but not have the highest oxygen consumption. 
  1. Description in detail of method or procedures (The following are important and key items that should be included when formulating ANY AND ALL research plans.)
  • Procedures: 
    • Materials:
      • Oxygen Tracker
        • Product Name: Fingertip Pulse Oximeter Bluetooth Blood Oxygen Saturation Monitor and Pulse Rate Monitor for Apple and Android, with OLED Screen 2 X AAA Batteries and Lanyard 
        • Brand/Manufacturer: HealthTree 
        • Item Weight: 2.12 ounces 
        • Product Dimensions: 2.36 x 2.76 x 1.97 inches
        • Color: Black 
        • ASIN: B09MVYNYQ5
        • Country of origin: China 
        • Item Model Number: JKS50B 
  • Groups (4):
  1. Running Only (5 participants) 
  2. Biking Only (5 participants) 
  3. Muscle Training/Lifting Only (5 participants) 
  4. All types of exercise (5 participants) 
  • Age Range: 17-50
  • Workout Outline 
  1. Running 
  • Running at steady pace on the treadmill at 6 mph for 30 minutes with no incline
  1. Biking 
  • Cycling for at least 30 minutes at a steady pace around 15.5 mph speed at a 1% incline 
  1. Muscle Training/Lifting 
  • Bench Press 35 lbs 10 reps x 4, Rest Time: 30 seconds 
  • Shoulder Press 40 lbs 15 reps x 3, Rest Time: 30 seconds 
  • Deadlift 50 lbs 20 reps x 2, Rest Time: 30 seconds 
  • Bent-Knee Deadlift 40 lbs 15 reps x 4, Rest Time: 30 seconds 
  • Half Squat 40 lbs 20 reps x 3, Rest Time 30 seconds
  1. All types of exercise
  • Run at a steady pace on the treadmill at 5-6 mph for around 15 minutes with no incline 
  • Bench Press 35 lbs 10 reps x 4, Rest Time: 30 seconds 
  • Shoulder Press 40 lbs 15 reps x 3, Rest Time: 30 seconds 
  • Instead of this workout, could play a sport (Basketball or Volleyball) for 30 minutes    
  • Exercise is being done at school, the gym, or at their home 
  • Participants below 18 are being monitored by their coach or their parents and participants above 18 are held accountable for themselves because they signed the consent forms 
  • Participants can change the weights and number of reps based on what they can do and what they can’t 
  • Participants determine themselves if they are capable of completing these exercises 
  • Participants can change an exercise or opt out of an exercise 
  • Steps: 
    • For a duration of 3 weeks (Jan 2 - Jan 20), for 5 days a week, each participant will perform at least 30 minutes of their workout and measure their oxygen levels before and then measure their oxygen levels after 
      • This will test to see which workout allowed for oxygen consumption to be maximized 
  • Data will be stored on a spreadsheet, with each participants names and their oxygen levels 
    • Participants names will only be revealed to me and will not be mentioned in the final product 
    • Human participants research:
  • Participants:
    • There will be a mixture of all genders, any racial/ethnic composition, and any age. There will be no participants part of the vulnerable populations. 
  • Recruitment: 
    • The participants will be from the high school and my father’s friends. They will be invited to participate through request. 
  • Methods: 
    • The participants will be asked to perform 30 minutes of their given workout 5 days a week for 3 weeks and record their oxygen levels before and after the workout. 
  • Risk Assessment
    • Risks
      • There most likely will not be any risks or discomforts. To minimize the risks, the participants can workout at any time of the day and it only has to be for a duration of 30 minutes. 
    • Benefits
      • The benefits are that it can improve the brain health of the participants, help manage weight, strengthen the bones and the muscles, and allow the person to stay active and be a healthier individual. 
    • Protection of Privacy: 
      • The participants' full name, gender, and age will be collected. This data will be confidential and only I will know the data, and none of the participants personal information will be shared in the final product of the research. This data will be stored on a google spreadsheet and at the end of the study the data will be discarded, so that the data can’t be leaked and can’t be accessed by anyone else. 
    • Informed Consent Process: 
      • I will inform the participants about the purpose of the study by talking to them in person and explaining what they have to do and making sure they give their consent first. I will make sure to inform them in the beginning that this study is voluntary and that if they don’t feel comfortable being a part of the study, they may leave. 
  • Data Analysis: 
    • Tracking the oxygen levels before and after the workouts will allow for the data to be compared 
      • Check to see which workout provided the most efficient way to maximize oxygen consumption 

Questions and Answers

1. What was the major objective of your project and what was your plan to achieve it? 

       a. Was that goal the result of any specific situation, experience, or problem you encountered?  

- The goal of this project was to determine how to maximize you oxygen consumption while working out. 

       b. Were you trying to solve a problem, answer a question, or test a hypothesis?

- I was trying to test a hypothesis. 

2. What were the major tasks you had to perform in order to complete your project?

       a. For teams, describe what each member worked on.

- Each person worked on different workouts and they had to measure their oxygen consumption before and after their workout each time they worked out. There were 4 different workout groups and they had to workout for 5 days a week for at least 30 minutes. 

3. What is new or novel about your project?

       a. Is there some aspect of your project's objective, or how you achieved it that you haven't done before?

- There isn't any aspect that I have achieved that I haven't done before. 

       b. Is your project's objective, or the way you implemented it, different from anything you have seen?

- No, the objective isn't anything different that I haven't seen. 

       c. If you believe your work to be unique in some way, what research have you done to confirm that it is?

- My work is not unique, there have been other research projects similar to this. 

4. What was the most challenging part of completing your project?

      a. What problems did you encounter, and how did you overcome them?

- The problems that I encountered were determining how accurate these results were because since the participants were manually inputting the information it may have been inaccurate. 

      b. What did you learn from overcoming these problems?

- I learned that it is best to try to use the results and accurately depict them and analyze them. 

5. If you were going to do this project again, are there any things you would you do differently the next time?

- Next time, I would have more participants and widen the types of work outs. 

6. Did working on this project give you any ideas for other projects? 

- I want to test how to maintain a healthy heart rate and what that would consist of. 

7. How did COVID-19 affect the completion of your project?

- COVID-19 didn't affect the completion of my project.
