Injuries often occur because athletes must maintain balance on unstable water surfaces while enduring high speeds and impacts, which place stress on joints and muscles. Dr. Taeseob Kim, an orthopedic surgeon at Bupyeong Himchan Hospital, explains, ‘These activities demand considerable strength to maintain posture, and when the body is tense during impact, joints are more prone to injury.’ He emphasizes the importance of choosing sports suited to one’s skill level and mastering proper technique to reduce risks.
Shoulders and Knees Most Vulnerable
Waterskiing and wakeboarding, driven by high-speed motorboats, require sustained full-body tension and often cause overuse injuries. The rotator cuff, a group of muscles and tendons that stabilize the shoulder, is particularly vulnerable. Persistent pain in the front of the shoulder or outer arm—especially when lifting the arm—may signal a tear that warrants medical evaluation.
Surfing also places significant strain on the shoulders. Repeated paddling can cause inflammation or muscle fatigue that may progress to tendon tears if left untreated. Knee injuries are likewise common, with the anterior cruciate ligament (ACL) and meniscus vulnerable to twisting during falls. Symptoms such as pain, swelling, or joint locking warrant prompt diagnosis and treatment.

Preparation Prevents Injuries
Many water sports injuries result from insufficient preparation, especially among vacationers who overexert themselves after limited practice. Stretching and mobility exercises are vital to improve flexibility in key joints such as the shoulders, knees, and lower back.
For waterskiing and wakeboarding, a crouched, horse-riding stance with eyes fixed forward is recommended. Relying on lower body and core strength, rather than the arms, helps maintain balance and reduces injury risk. When landing, bend the knees to absorb impact. In case of a fall, tuck the chin and curl the body to lessen the collision force with the water.
Surfers should focus on shoulder-strengthening exercises and choose waves suited to their abilities. When standing on the board, relying on leg and core strength rather than the lower back ensures stability. Keeping ample distance from other surfers also helps avoid collisions.
Prompt Response Enhances Recovery
If a joint injury occurs, rest immediately and avoid moving the affected area. Apply an ice pack for 15 to 20 minutes to reduce pain and swelling, and use a bandage or compression wrap to control edema.
Dr. Kim warns, “If pain persists beyond a few days or worsens, it is unlikely to be simple muscle soreness. Ignoring symptoms can lead to chronic problems, so if swelling or warmth continues, apply ice and seek medical attention promptly.”
As South Korea’s rivers and coasts continue to draw water sports enthusiasts, experts underscore that thorough preparation and proper technique are the strongest safeguards against the inherent dangers of these exhilarating pursuits.
