The document summarizes a student's science project investigating which sport develops the strongest biceps. The student hypothesized that gymnasts or tennis players would have the strongest biceps. They surveyed classmates on their sports and tested bicep strength of those who play different sports by timing how many times they could lift a 1kg weight in 1 minute. The results showed that softball players had the strongest biceps. The student was surprised gymnastics did not score higher and that dancers had the weakest biceps. They concluded that softball requires more arm usage than hypothesized sports.

1. Question
Which sport develops the
strongest biceps?

2. Why I Chose This
Question
With the Olympics on TV and lots of athletes from around the
world competing in lots of different sports it seemed a good
time to incorporate sports into my project. I have always been
interested in sport, and in particular I like gymnastics. I have
meet Matthew Palmer who is a gymnast that competed in the
commonwealth games. He is originally from Blenheim. I am
interested in how the body works, and staying fit and healthy.
My family enjoy lots of sports and a healthy lifestyle.
I have been doing some background research on the body, and
have decided to focus on muscles and how they work. There
are many muscles in the human body, so I have decided to look
at arm muscles in particular.

3. Hypothesis-What I
Think
• I think that the people who participate in
tennis or gymnastics will have the strongest
biceps because you use your arms to hold
the racket and hit the ball when your
playing tennis.You use your arms for
balance and support in gymnastics.

4. TEST MATERIALS
• Survey sheet
• Timer/clock
• 1kg water bottle
• Some people around the same age
that do different sports.
• pencil

5. Test-Method
• 1. Take pencil and survey sheet. Survey the
class to find out what sports everyone
does.
• 2. Choose some people in the class aged 9
or 10 year olds that do different sports.
• 3. Fill a water bottle with rocks (so it weighs
1kg)
• 4. Test each person separately. Get the
person to stand against a wall holding the
1kg weight in their right arm.

6. • 5: Tell each student when you say GO lift the 1kg
weight as many times as you can.
• 6. Time them for 1 minute.
• 7. Say GO and count how many times they can
lift the weight.
• To make the test fair make sure that the
students hand touches the wall when they lower
the weight. Also make sure that when they lift
their arm that the weight touches their shoulder.
• measure

7. Results
I counted how many times the students could lift the 1kg
weight in 1 minute The results were as follows:
• Didn’t do any sports lifted the weight 35 times.
• Play softball lifted it 75 times.
• Dance lifted it 28 times.
• Play lots of sports lifted it 51 times.
• Play soccer lifted it 40 times.
• Play taekwondo lifted it 44 times.
• Gymnastics lifted it 44 times.
• Play squash lifted it 41 times.
• Play tennis lifted it 38 times.
• Play netball lifted it 42 times.

8. RESULT
I found out that the people who play softball
have the strongest biceps.
I also found out that the people who dance
have the least strongest biceps.

9. Blue bars indicate the number of people who
participated in my survey.

10. Conclusion
Of the sports the children in my class do, those that play softball have the
strongest biceps. I am surprised that gymnastics didn’t score higher.
My results have proven my prediction wrong, I though that people who do
gymnastics or tennis would score higher on my strength test.
I think the people who play softball had the strongest biceps because you use
your arms to hold the bat, hit the ball and throw the ball in softball. I also
think the people who dance have the least strongest biceps because you only
use your arms for graceful movements when you are dancing.
If I did this test again I would ask the people that got the highest
scores if they did lots of other sports and if they did sports in Summer
and Winter ( all year round ) This could have effected my results.

11. Future Action
• I could find out if the type of sport people
do result in stronger legs.
• I think dancers and cyclists would have
stronger and bigger leg muscles!

12. • I found out that the children that do more
sports have better endurance. They got
higher scores on the task.
• Boys and Girls that do 3 or more sports
have the same higher levels of endurance.
• The type of sport didn’t really matter but
the top 4 all played a ball passing and
hitting sport- netball, basketball, softball.
