Proper Usage of Resistance Training Aids (Paddles / Resistance Pants)

Introduction

Swimming training aids/tools are an important part of modern swimming training. From the most basic kickboard and pull buoy to advanced paddles, drag shorts, and parachute drags, each aid has its specific training purpose.

However, using more aids is not necessarily better. Incorrect use of training aids can not only significantly diminish training effectiveness but may also reinforce faulty movement patterns and even lead to sports injuries in areas such as the shoulders and knees. This article will focus on the two most common categories of aids—paddles and drag shorts—and explain their correct usage and common mistakes.

Paddles

Function and Purpose

Paddles are rigid, paddle-shaped aids worn on the palms that increase the surface area of the hand and forearm. Their main training effects include:

• Enhanced feel for the water: The larger contact area makes it easier for swimmers to perceive the distribution of pressure during the pull.
• Strengthened pulling muscles: Greater resistance provides a stronger training stimulus to the latissimus dorsi and pectoralis major.
• Enforced high-elbow position: With well-designed paddles (especially finger-loop models), if the elbow drops, the paddle will literally “slip off,” forcing the swimmer to maintain a high-elbow position.

Correct Usage

Item	Recommendation	Explanation
Size selection	Slightly larger than the palm	Oversized paddles mask technical flaws rather than correct them
Timing of use	Technique sets or power sets	Not recommended for prolonged use during aerobic endurance sets
Pairing with a pull buoy	Recommended	Eliminates kick interference, allowing focus on upper-body technique
Volume per session	No more than 30% of total training volume	Excessive use increases the risk of shoulder injury

Common Mistakes

Mistake 1: Bigger is better
Many swimmers choose paddles far larger than their palms, believing that greater resistance means greater training effect. In reality, oversized paddles allow swimmers to “pull water” even with a dropped elbow and poor catch position, thereby masking technical problems.

Mistake 2: Wearing them for long aerobic sessions
Paddles significantly increase the load on the shoulders with every stroke. Wearing them for extended aerobic training (e.g., swimming 3,000 meters with paddles the entire time) is one of the leading causes of shoulder impingement injuries.

Mistake 3: Using them before technique is stable
Paddles amplify existing technical issues (both correct and incorrect ones). Therefore, it is recommended to introduce paddle training only after basic technique (high-elbow catch, correct hand entry point) has achieved a certain level of stability.

Drag Shorts

Function and Purpose

Drag shorts are loose-fitting shorts worn over swimwear that create additional water resistance while swimming. Their main training effects include:

• Aerobic endurance training: More output is required at the same speed, improving aerobic capacity.
• Power training: Simulates the feeling of “riding into a headwind,” building the strength needed to overcome resistance.
• Speed perception contrast: After removing the drag shorts at the end of a session, swimmers experience a noticeable sense of speed, which helps build speed awareness.

Correct Usage

• Suitable users: Swimmers with relatively stable technique. For those with unstable technique, the reduced speed caused by drag shorts may increase tension and worsen body position.
• Training distance: Focus on moderate-distance sets (100–400 meters); avoid extremely long distances to prevent breakdown in form.
• Pace setting: A 10–20% reduction in speed while wearing drag shorts is normal; do not force the original pace at the expense of technique.
• Contrast training after removal: One of the greatest benefits of drag shorts training is the “sensory contrast” after taking them off. It is recommended to swim a set immediately after removal to feel the change in speed perception.

Other Training Aids Overview

• Kickboard: Trains kicking technique while isolating upper-body interference; suitable for all levels.
• Pull Buoy: Keeps the legs afloat and stationary, isolating the kick to focus on upper-body pulling technique.
• Parachute Drag: Provides greater resistance than drag shorts, mainly used for sprint power training; less suitable for everyday use by recreational swimmers.

Practical Recommendations

• Establish a “training aid usage plan”: Before each session, decide the primary goal (technique improvement, power, or aerobic), then choose the corresponding aid to avoid random usage.
• After using paddles, observe whether there is any shoulder discomfort (soreness or tightness). This is a warning sign that you should reduce usage or pause entirely.
• When first using drag shorts, start with short sets of 200–400 meters to confirm that your technique does not break down under increased resistance, then gradually increase usage.

Conclusion

Swimming training aids are tools, not magic. Used correctly, they can accelerate technical progress and physical development; used incorrectly, they can lead you further down the wrong path and even cause injury. Understanding the design purpose of each aid and selecting the appropriate one based on your technical level and training goals is the key to maximizing the benefit of every session.
