Guide to Stretching and Flexibility Training for Swimming
Q: Why is it necessary to stretch before and after swimming? Do Stretch Bands Really Work?
A: 游泳是全身性運動,肩、背、髖、踝關節活動度直接影響划水效率與打水推進力。拉伸帶 (Stretch Cord / Resistance Band) 能輔助泳手在岸上完成模擬划水動作,強化肩袖肌群、提升關節活動度,是專業泳手提升成績與預防受傷的關鍵工具。
Q: How to choose the poundage of resistance band?
A: 阻力帶通常以顏色區分磅數。輕磅 (黃/紅) 適合熱身與初學者;中磅 (綠/藍) 適合一般訓練;重磅 (黑/紫) 適合進階肌力訓練。建議從輕磅開始,動作標準後再逐步增加,避免拉傷肩膀。
Q: Is stretching equipment suitable for use at home? What equipment is needed?
A: Very suitable. Stretch and resistance bands are small and easy to store, making them ideal for home training. Paired with the Door Anchor, you can perform simulated paddling training on any door frame in your home, no gym space required.
