Transcript of Science Investigation

How does a specific style of dance affect a dancer’s heart rate?

The student can apply this experiment to real life by using it to test a dancer’s heart rate if he or she is not in great condition. The student can use this experiment in real life by using it to see if a dancer can handle the energy needed for the routine.
Data and Observations

Normal: 80 bpm
Contemporary:93 bpm
Jazz: 105 bpm
Hip Hop: 96 bpm

How Dance Affects One's Heart Rate

The reason the student exhibitor is performing this experiment is to find out what styles of dance affect her heart rate. As a dancer, the exhibitor is interested in knowing which specific styles of dance affect her heart rate to fluctuate more or less. This experiment will allow the exhibitor to understand how her body reacts to contemporary, jazz, as well as, hip hop styles of dance.
The exhibitor of this experiment, who is also the researcher, studied the needed information to analyze the effects of specific styles of dance on a dancer’s heart rate. The exhibitor was able to determine if certain styles of dance required more energy from the performer or less. By studying heart rate before and after performance, data was collected to determine that the higher energy of the dance the heart rate was calculated after the routine was performed. Jazz, contemporary, and hip hop styles of choreography were performed. At the start of each performance, the exhibitor and dancer’s heart was measured. Afterwards, the heart rate reflected a rise in the heart’s pulse rate. Throughout the research process, it was concluded that the importance of health was vital. With all of the components considered, reflected upon, and analyzed it was determined that the specific style of dance does have a direct effect on the dancer’s heart rate due to the specific movements, muscle strength, and speed necessary to complete the choreography.

Background Information
Dancing affects one’s heart rate in many ways as it is a fast paced and hard working sport. Dancers need to understand that dance can be dangerous and that the dancers need to mindful and careful with their health. In order to stay healthy, dancers need to maintain good eating habits, and be physically fit in order to perform at their
best level.
A person’s heart rate, or pulse, is the number of times their heart beats per minute. Normal heart rate varies from person to person. Knowing one’s heart rate is important and can help understand one’s body better. When resting, adult human heart beats at about 70 bpm (males) and 75 bpm (females). However, this rate varies among people and can be lower in serious and active athletes. Changes in heart rate can be for a range of reasons which may include illness, fatigue, drug use, exertion, stress, and anxiety. People who are very active experience increased heart rate, respiration, as well as, perspiration.
If a dancer performs a fast paced routine with extensive choreography then their heart rate will increase due to the physical energy required to perform the specific style of dance.
Experiment: Procedures
1. First, the dancer has to find a person to record the dances and she needs a place to dance
2. Then, the dancer has to perform the first routine
3. Check and record heart rate
4. Repeat 2-3 two more times
5. Compare heart rates and write down results

Experiment: Variables
Independent (being manipulated or changed)- style of dance

Dependent (being measured)- dancer’s heart rate

Constants (stay the same)- dancer, video
camera, dancing area

Control (being compared)- none

Experiment: Materials
1. Dancer
2. Dance shoes
3. Area with space to dance
4. Video camera
5. Dance attire
6. Stopwatch

Analysis/ Results
In the student’s experiment process, she collected data, took pictures, and was videoed while dancing. Her heart rate before she performed all of her routines was 80 bpm. After her first jazz routine, her heart rate increased greatly. It went up to 105 bpm. This dance was very fast paced and high energy and this is the reasoning related to why the heart rate increased. The exhibitor’s next routine, contemporary, was not as fast paced as the jazz dance. At this time, the exhibitor’s heart rate went up to 93 bpm. Lastly, the exhibitor performed a hip hop routine. This dance was very fast and quick; therefore, her heart rate rose to 95 bpm.

The student who performed this experiment formed a hypothesis before experimenting to solve her problem statement. In the end of the experiment process, her hypothesis was proven correct. If she was to redo this experiment, she would have made sure to take longer breaks in between dances so she was not as tired. This experiment was very successful for the student despite her minor error. She learned how to measure heart rate and how dance really affected her physical body. She enjoyed this experiment greatly, as dance is a huge part of the exhibitor’s life and takes up 20-30 hours of her weekly schedule.
Analysis/ Results (continued)
The exhibitor collected all of the required data in the time span of a week. The data goes from a heart rate that is increasing to decreasing and then increasing once again. In order to perform her routines to her best extent, the exhibitor had to take a few quick breathers in between each routine. In the line graph shown above, it explains how her heart rate sped up and slowed down.
For this project, all of the following people and places have contributed choreography that the dancer/researcher has performed in the videos utilized for this experiment:

Contemporary and Hip Hop routines choreographed by Ms. Dani Solano

Jazz routine choreographed by Miss Casey Rosenberg (one of the many Miami Heat Dancers).

Focal Point Dance Studios
