03A positive correlation exists between speed and swimming speed.

Application

Design takeaway

Designers of athletic training programs and equipment should focus on exercises and tools that build muscular strength and speed to improve butterfly stroke efficiency and velocity.

How to apply

When designing training regimens or performance analysis tools for swimmers, prioritize metrics and interventions that target muscular strength and speed, as these are directly linked to stroke length and overall velocity.

Project actions

01Consider how different physical attributes influence the efficiency of a specific movement.
02If your design involves physical activity, think about the underlying physiological factors that affect performance.

Method & Evidence

AimTo investigate the relationship between physical fitness components (muscular strength, endurance, speed, flexibility, agility) and kinematic parameters (arm stroke length, stroke frequency, swimming speed) in the butterfly stroke.

MethodCorrelational study

ProcedureParticipants completed a physical fitness assessment covering muscular strength, endurance, speed, flexibility, and agility. Their butterfly stroke kinematics, including arm stroke length, stroke frequency, and average swimming speed over 25m, were then measured. Pearson correlation coefficients were calculated to determine the relationships between fitness variables and kinematic parameters.

Strengths & Limitations

Strengths

+Directly links physical attributes to specific performance metrics.
+Provides actionable recommendations for training.

Limitations

The study used a very small group of experienced swimmers, so the findings might not apply to beginners or people with different fitness levels.

Reliability & validity

The study's validity is supported by the use of established physical fitness dimensions and kinematic analysis. Reliability could be enhanced with a larger sample size and repeated measurements.

Think critically

To what extent can these findings be generalized to other swimming strokes or sports that require different types of physical exertion?

Design Principles

"Optimize human physical capabilities to enhance biomechanical performance in specific motor tasks."

Understanding these biomechanical relationships allows for targeted training and design interventions. For instance, equipment or training programs can be developed to specifically enhance these physical attributes, leading to improved performance and potentially reducing injury risk by optimizing movement efficiency.

What This Means for Your Design

If you're stronger and faster, you can swim the butterfly stroke with longer arm movements and at a quicker pace.

How to use in your project

1.Use this study to justify focusing on specific physical attributes in your design, such as strength or speed, if your project aims to improve athletic performance.

Paragraph starter

This study by Alawamleh and Alkasasbeh (2024) highlights a significant correlation between physical fitness components and swimming kinematics. Specifically, it found that enhanced muscular strength positively impacts arm stroke length, while improved speed correlates with increased stroke frequency and overall swimming velocity in the butterfly stroke. These findings suggest that for designs aiming to improve athletic performance, particularly in swimming, focusing on enhancing fundamental physical attributes like strength and speed can yield direct improvements in technique and efficiency.
