In the realm of competitive swimming, swimmers and coaches are always on the lookout for ways to shave precious seconds off race times. One area that has gained significant traction in recent years is the optimization of swim techniques, particularly focusing on hand placement, stroke frequency, and body position during the critical moment of the catch and pull. This article explores the concept of "CM improvements" - an innovative approach to enhancing swimming performance by maximizing the power generated during the catch phase of the freestyle stroke.
Before delving into the intricacies of CM improvements, let's first understand the fundamentals of the freestyle stroke and the importance of the catch phase. The freestyle stroke, also known as the "front crawl," is the fastest and most energy-efficient swimming stroke. During the stroke, the swimmer's body maintains a horizontal position, with the arms moving in a circular motion under the water. The catch phase, which occurs as the hand enters the water, is a crucial aspect of the stroke as it generates propulsion and sets the stage for a powerful pull through the water.
Understanding the Catch Phase
The catch phase initiates as the swimmer's hand breaks the water's surface and begins to move downward and backward. During this time, the swimmer's hand and forearm should form a C-shape, with the palm facing backward and the fingertips pointing downwards. This position allows the swimmer to maximize their surface area, which in turn creates resistance and generates forward momentum.
Traditionally, swimmers have focused on the high elbow position during the catch phase to facilitate a strong pulling action. However, CM improvements take a different approach, emphasizing the role of the hand and fingers in generating power and minimizing drag during the stroke. By optimizing the hand and finger placement, swimmers can improve their catch efficiency, reducing the energy expended during each stroke and ultimately enhancing their swimming performance.
Maximizing Power with Hand Placement
A key aspect of CM improvements is the strategic placement of the hand during the catch phase. In essence, swimmers should aim to place their hands higher on the back of the forearm, creating a steeper angle of attack relative to the oncoming water. This positioning optimizes the swimmer's ability to redirect the water flow, generating more propulsion and minimizing drag. To achieve this, swimmers should focus on entering the water with their hand positioned high on the back of their forearm, with the thumb leading the way.
To further illustrate this concept, consider the analogy of hitting a golf ball. A golfer would never hit the ball flat on with their clubface, as this would result in minimal power transfer. Instead, the golfer employs a steep angle of attack, allowing them to drive the ball forward with maximum force. Similarly, swimmers should strive to employ a steeper angle of attack during the catch phase, maximizing their power output and enhancing their swimming performance.
Incorporating Finger Action
In addition to optimizing hand placement, CM improvements emphasize the role of finger action during the catch and pull phases of the stroke. By actively engaging the fingers and spreading them wide, swimmers can increase the surface area of their "paddle," further enhancing their ability to redirect water flow and generate propulsion. To incorporate finger action into their stroke, swimmers should focus on spreading their fingers wide as their hand enters the water, maintaining this position throughout the catch and pull phases of the stroke.
Swimmers can practice this technique by performing drills that emphasize finger action, such as the "fist grab" or "corkscrew" drill. These drills encourage swimmers to engage their fingers actively during the stroke, helping them develop the muscular memory required to incorporate this technique into their regular freestyle training.

Body Position and Stroke Rate
While CM improvements focus primarily on optimizing hand and finger placement during the catch phase, maintaining an efficient body position and stroke rate are equally crucial for enhancing swimming performance. To maximize the benefits of CM improvements, swimmers must maintain a horizontal body position throughout the stroke, minimizing drag and preserving their energy. Additionally, swimmers should strive to maintain a consistent stroke rate, balancing power and efficiency to maximize their swimming speed.
To maintain a horizontal body position, swimmers should focus on minimizing movements of their head and hips. By keeping their head and hips still, swimmers can reduce unnecessary Suprema energy expenditure and maintain a stable platform for their arms and legs to work from. They can also employ training aids, such as a snorkel or pull buoy, to help maintain a stable body position during practice.
Stroke Rate and Efficiency
In addition to maintaining a stable body position, swimmers must also balance power and efficiency in their stroke rate. A faster stroke rate can generate more power, but it also increases the energy expended during each stroke. To maximize performance, swimmers should aim to find the optimal balance between power and efficiency, maintaining a stroke rate that allows them to generate sufficient propulsion without expending excess energy.
To determine the optimal stroke rate, swimmers can use target times for specific distances, such as 25 meters or 50 meters. By dividing the target time by the number of strokes taken, swimmers can calculate their stroke rate and adjust their training accordingly. For example, if a swimmer aims to complete a 50-meter sprint in 25 seconds and takes 12 strokes per 25 meters, their stroke rate would be 102 strokes per minute (SPM) for the 50-meter sprint.
Incorporating CM improvements into your swimming training can lead to significant enhancements in performance, helping you shave precious seconds off your race times. By optimizing hand and finger placement, maintaining a stable body position, and balancing power and efficiency in your stroke rate, you can unlock your full swimming potential. To get started, consult with a certified swimming coach or attend swimming technique workshops to ensure you're incorporating these principles safely and effectively. Happy swimming!
