Sprinting is a powerful, faster form of
running which can only be performed in short period. When sprinting, a runner
maintains his full speed for the entire run. In competition, sprint races
include the 100, 200, and 400 meter dash and are typically run in less than 60
Based on (Dani, 2017), there are three
stages of sprinting, namely drive, maximum velocity and maintenance. 2
sprinter begins in the drive phase, when he bursts from a dead still position
into a sprint. The sprinter will start in a crouched position, in the starting
blocks, ainter should lean with his
whole body rather than bending at the hips. In this stage, the foot is in
contact with the track below or slightly behind the hips.
2. Maximum Velocity
the runner proceeds to the maximum velocity phase. Here, the runner becomes
fully erect in his posture, standing tall without his hips lowered. The runner
achieves his maximum speed

power. For many 100 metre sprinters the winner is the athlete who slows down
the least. Power is one of the essential elements to speed.

they all refer to how fast an athlete can achieve maximum velocity within a

all joints and has numerous effects on performance. Lack of good flexibility
can have a direct negative impact on speed due to the limitations of joint
Therefore, based on (Andrew,

Difference in Time
Individual Result (Liang Ding Lern)
The overall graph of my
velocity is increasing and decreasing over the distance that is covered by me.
The maximum velocity that I had achieved is 10.10 m/s during 50m, while the
lowest velocity I got is 5.56 m/s at the beginning of the sprint.
Maurice Green Result (1999 World Championship Seville,
Difference in Time (second)
Difference in Velocity (m/s)
The velocity achieved by
Maurice Green increases and remain constant throughout the whole sprint for
100m. While the velocity I had achieved is imbalance as it increases and
decreases throughout the whole sprint for 100m. The maximum velocity of Maurice
Greene is 11.90m/s and mine is 10.10m/s. The minimum velocity of Maurice Greene
is 5.38m/s and mine is 5.56m/s.
As for acceleration,
Maurice Greene graph shows that it increases at first and then decreases
constantly through the whole sprint of 100m. While mine shows it increases and
decreases simultaneously throughout the whole sprint of 100m. The maximum
acceleration achieved by Maurice Greene is 4.21m/s² and mine is 3.09m/s². While
the minimum acceleration of Maurice Greene is -0.16m/s² and mine is -1.44m/s².
Comparison of my result and Maurice
the beginning of the 100m sprint, my starting velocity is higher than Maurice
Greene which is 5.56m/s. The reason behind this is because of the difference of
my reaction time and Maurice Greene’s reaction time based on (editorialtoday.com,
2013). 3 Throughout the whole sprint, my velocity increases and decreases
simultaneously, while Maurice’s velocity increases constantly and is maintained
throughout the whole race. The reason behind this is because I had not gone
through any sprinting training and the sport that I usually play does not
require full sprinting only but in certain situation in the match of football
requires it. As for Maurice Greene, he is a professional sprinter which only
focused on sprint, hence he had been trained well in order to maintain his
velocity. Furthermore, the technique of sprinting also plays a vital part
during sprinting. In my opinion, the sprinting style executed by myself is
incorrect while Maurice’s technique is well trained hence it gives a
for acceleration, Maurice Greene acceleration is much higher than mine at
4.21m/s². Referring to (editorialtoday.com, 2013), the power generated by
Maurice Greene is very high while mine is lower than his, therefore generating
the maximum acceleration at only 3.09m/s². 3 Besides that, Maurice Greene
undergoes deceleration at 70 meter and 100 meter, while I faced deceleration
multiple times at 40 meter, 70 meter, 80 meter and 100 meter. The reason to
explain this phenomena is because of muscle fatigue. Maurice Greene faces
muscle fatigue much lesser than me hence making him gain the advantage of less
deceleration and more on acceleration and helping him to finish the 100m sprint
way faster than me.
Comparison of my result and the stages of
The driving phase of me is at the
beginning of the 100m sprint, where I start in a crouched position and pushes
off while leaning forward. In this phase I had achieved the highest velocity at
5.56m/s, which is much higher than Maurice’s starting velocity.
The maximum velocity I had got is 10.10m/s.
The maximum velocity should be achieved during the halfway of the 100m sprint
in order to get faster and finish the race in a short period of time. While
Maurice’s maximum velocity is achieved at 60m and also higher than mine by
1.8m/s which allow him to have the advantage to finish the race at a short
period of time.
Honestly, the maintenance of me is very
poor because of the results of the graph shows that my velocity and
acceleration is increasing and decreasing simultaneously. I would need to
undergo training in order for me to improve and maintain my speed. Through
this, I will be able to achieve a faster sprint and finish the race at a short
period of time.
Question & Answer from Practical
shown in Page 5,6 & 7)
10m, which is the beginning of the 100m sprint has the lowest velocity at
5.56m/s. This is because I have to focus on applying a large amount of force
onto the ground to achieve the desired acceleration, rather than taking more
50m, which is at the halfway of the 100m sprint has the maximum velocity at
10.10m/s. The reason is I had minimise braking forces, which refer to those
forces which act in the opposite direction of the desired movement and increase
vertical propulsive forces based on (Epicontrol,2016). 4
10m, the beginning of the 100m sprint has the highest acceleration at 3.09m/s².
This is because I had focus on using a large amount of force onto the ground to
achieve the desired acceleration in order to take off and start sprinting.
