Speed in Athletic Performance

In the world of athletics, speed is an essential component that often determines the outcome of a competition. It's a complex characteristic that can be broken down into different categories and influenced by a host of factors. This article aims to provide a comprehensive understanding of speed, its classifications, the factors that influence it, and how it can be improved through training and supplementation.

Defining and Classifying Speed

Speed, also known as motor rapidity, is a specific athletic ability that can be segmented into two key categories:

  1. Reaction Speed: This is the ability to respond to a stimulus in the shortest possible time. It is primarily a nervous characteristic but also partly conditional. An example of an athletic activity driven by quick reaction is dodging in combat sports.

  2. Action Speed: This refers to the ability to execute an athletic movement characterized by cyclic frequency and simple acyclic action, especially when faced with minimal physical resistance. It relies heavily on the nervous system but also significantly on cellular energy metabolism. An example of an athletic activity based on action speed is sprinting in short-distance races.

Reaction speed and action speed are forms of pure speed. However, there are also more complex forms of speed where strength and/or endurance play a crucial role. This is the case with force velocity, also known as fast force, which can be differentiated into frequent athletic gestures (resistance to fast strength) and continuous athletic gestures that require maximum resistance to speed.

Phases of Speed and Influential Factors

Speed in physical movements involves four key stages:

  1. Reacting to a signal.
  2. Speeding up.
  3. Reaching peak speed.
  4. Slowing down (especially in endurance speed).

Several elements impact how fast someone can move. Personal traits like age, gender, body size and shape, overall health, skill level, and social factors matter a lot. Mental and sensory aspects are also important - things like focus, quick thinking, drive, determination, experience, ability to predict, mental toughness, and learning skills.

The way our nervous system works plays a big role too. This includes how well and how often our brain sends signals to our muscles, how our nervous system balances being alert and relaxed, and how our nerves and muscles work together. Even the chemistry of our brain and nerves counts.

Finally, our muscles and tendons are crucial for speed. Factors like the type and distribution of muscle fibers, muscle size, how quickly a muscle can contract, flexibility and stretchiness of muscles and tendons, muscle length, the mechanics of how muscles generate force, energy use, and muscle temperature all significantly affect how quickly we can move.

Speed and Energy Use

Speed depends mostly on how well our muscles use energy sources like adenosine triphosphate (ATP) and creatine phosphate (CP). Our muscles also rely on another system, the anaerobic metabolism, which breaks down glucose without oxygen. To run faster, it’s essential to improve muscle levels of ATP and CP, muscle power, and the ability to handle lactic acid.

Boosting Speed with Supplements

To sprint faster, it’s crucial to have enough ATP and CP in our muscles. Training and good nutrition can increase the levels of creatine phosphate, a key molecule in this process. For some people, taking extra creatine as a supplement can help boost their speed.

Training for Speed

Starting speed training early is ideal, but even adults can see improvements within the first eight weeks. This training increases muscle energy stores and enzymes that help produce and use energy. Effective speed training involves being well-rested, training at maximum effort, adapting to different conditions, and focusing on specific movements. Remember, it’s important to master the technique before going full speed.

The Link Between Speed and Strength

Speed is closely linked to muscle strength. Sprinters train with heavy weights to maximize strength, which helps in faster nerve responses and better muscle coordination. Training also focuses on developing different types of strength, like the ability to quickly generate force and respond to changes in movement.

In conclusion, speed is a multifaceted athletic ability that can be improved through targeted training and supplementation. Understanding the different aspects of speed and the factors that influence it can help athletes optimize their performance and reach their full potential.
