Linear Acceleration Flashcards
(22 cards)
What is linear acceleration?
Linear acceleration refers to the rate of change of velocity of an object in a straight line.
Fill in the blank: The initial phase of linear acceleration is primarily focused on _____ power.
explosive
What body position is recommended for optimal linear acceleration?
A forward-leaning position with a low center of gravity.
Which muscle groups are most important for linear acceleration?
The quadriceps, hamstrings, glutes, and calves.
What role does arm movement play in linear acceleration?
Arm movement helps to drive the body forward and maintain balance.
True or False: The acceleration phase lasts for the entire sprint.
False
What is the recommended angle for a sprinter’s starting position?
Approximately 45 degrees.
What is the importance of reaction time in linear acceleration?
Faster reaction time allows for a quicker start and better acceleration.
What is one common mistake athletes make during linear acceleration?
Rising too quickly from the start position.
True or False: Maintaining a straight line is critical during linear acceleration.
True
What should be the focus of training drills for linear acceleration?
