【Research Review】Experimental Report on the Buoyancy Compensation and Thermoregulatory Mechanical Characteristics of Swimming Wetsuits: Exploring the Relationship Between Clinical Medicine and Athletic Performance (Article 1077)

Reference Journal Source: European Journal of Sport Science • International Scientific Research Findings Review Series

In the swimming section of the research field, the latest biomechanical analyses and nutritional studies have revealed more subtle physiological codes. This research report is compiled from cutting-edge literature in European Journal of Sport Science, providing a detailed analysis of the performance of subjects in the experimental and control groups. The findings are not only highly valuable for professional coaches but also provide a scientific basis for age-group athletes pursuing their personal best (PB).

Physiological Effects of Swimming Wetsuits on Body Streamlining and Drag Reduction

Wetsuits are typically made of 3-5mm neoprene. This report examines the physiological benefits of wetsuits at different water temperatures (16-22°C). The results confirm that wetsuits provide significant buoyancy compensation, particularly by lifting the swimmer’s lower body (pelvis and legs), reducing sinking drag by up to 12%-15%, improving the swimmer’s average 100-meter pace by 4-8 seconds, while also providing excellent thermal protection.

Hydrodynamics of Pool Turns and Underwater Dolphin Kicks

In pool training, every turn is an opportunity to improve efficiency. This hydrodynamic study analyzed the glide depth after pushing off the wall (optimal at 0.5-0.9 meters underwater), as well as the frequency of dynamic dolphin kicks before surfacing. The research indicates that wall push-off glide speed is extremely fast; initiating high-frequency, low-amplitude dolphin kicks before the glide speed drops to cruising speed can maximize the continuation of underwater momentum and reduce wave drag.

Key Research Conclusions and Practical Recommendations

Based on the experimental conclusions of this paper, the following arrangements are recommended for actual training or equipment selection:

• Biomechanical Feedback: Strengthening the gluteus medius and deep core muscles can significantly improve pelvic tilt during the stance phase, preventing uneven patellar loading under high intensity.
• Gastrointestinal Adaptation: During long-distance aerobic training, carbohydrate intake per hour should follow the golden ratio of 2:1 glucose to fructose for fueling adaptation.
• Hydrodynamic Drag Reduction: When swimming with underwater pulls, focus on engaging the EVF (Early Vertical Forearm) high-elbow catch technique, transferring the fulcrum of force to the latissimus dorsi to prevent rotator cuff strain.
• Equipment Efficiency Adaptation: When using carbon-fiber stiff-soled shoes or deep-section wheels, gradually increase weekly mileage to allow sufficient adaptation time for the Achilles tendon and joints.

Common Research Q&A (FAQ)

Q: What are the water temperature restrictions for wetsuit use in official races?

A: According to ITU regulations, wetsuits are generally permitted for age-group races when water temperature is below 22°C. If the water temperature exceeds 24.5°C, wetsuits are prohibited to prevent overheating and heatstroke.

Q: Why is optical heart rate monitoring on watches often inaccurate during swimming?

A: Water can seep into the gap between the sensor and the skin, and the repeated muscle compression and contraction of the wrist during strokes severely interferes with optical blood flow detection. Therefore, chest strap heart rate transmission remains the most accurate method for underwater heart rate monitoring.
