Reaction Time, Usain Bolt and the Pareto 80-20 Rule
November 30, 2008 by Jimson Lee
The 100 meters can be broken down into 3 parts:
reaction time,
acceleration to top speed,
speed endurance,
If you take Usain Bolt’s 9.69 time from Beijing 2008 as a percentage of time, you get:
Reaction time = 0.165 (1.7%),
0-60m without reaction time = 6.155 (63.5%),
60-100m including celebration = 3.37 (34.8%),
The term “Acceleration”, or roughly the first 60 meters or […]
Comparing 100 meter Freestyle and 400 meter Sprinting
November 27, 2008 by Jimson Lee
The 100 meter freestyle in swimming resembles the 400 sprint in running.
Their Elite times are in the mid 40’s second range and both events have similar energy systems: Alactic anerobic and Lactic anerobic.
Between 1968 and 2004, only 7 men has run under the magic 44 seconds barrier for the 400 meters (and two of them […]

Training and the 80-20 rule of Pareto’s Principle
November 20, 2008 by Jimson Lee
Last month, I wrote about the Plan-Do-Check-Act components of the Deming Cycle.
Another theoretical concept that applies to training is the 80-20 rule of Pareto’s Principle. This is not to be confused with the Law of Diminishing Returns.
The 80/20 Rule is a general rule of thumb, or as I call it, a “guesstimate”. It […]
