Swimming, water sports and spinal injury
Swimming is widely recognised as one of the best forms of exercise for the spine. The buoyancy of water reduces pressure on the joints, allowing many people with back pain to stay active with less discomfort.
However, like any sport, swimming and other water-based activities can place significant demands on the spine, particularly when technique is poor or activity levels increase suddenly.
As the summer months encourage more people to swim, paddleboard and water ski, it’s worth understanding how these activities can affect the neck and back, and when symptoms may indicate something more than simple muscle soreness.
Swimming and the spine
Different swimming strokes place different stresses on the spine. Recent research examining spinal loading during swimming found that the butterfly stroke places the greatest demands on the lower back. The powerful undulating movement requires repeated lumbar hyperextension, increasing stress on the lower lumbar spine, particularly the L5-S1 level.
The same review also identified increased loading through the cervical spine, as swimmers repeatedly lift the head and neck during the stroke.
By comparison, freestyle and backstroke were associated with lower spinal loading due to their more symmetrical movement patterns. For many people with existing back problems, these strokes are often better tolerated, although technique remains important.
Water sports and lower back strain
Water skiing, wakeboarding, paddleboarding, kayaking, and other popular summer activities place different types of stress on the spine.
Wakeboarding and water skiing require powerful twisting movements and repeated loading through the lower back, particularly when accelerating or recovering from falls. Paddleboarding demands continuous balance and core muscle activation, while prolonged standing on an unstable surface can fatigue the muscles supporting the spine.
For people who aren’t accustomed to these activities, the sudden increase in physical demand may result in muscle strain or aggravate existing spinal conditions.
Why sciatica can flare up
Many people only participate in water sports during holidays, meaning the body is often asked to perform movements it hasn’t practised for months.
Repeated bending, twisting, lifting equipment, or sudden impacts can irritate a pre-existing disc problem. If a lumbar disc bulges or herniates, it may compress the sciatic nerve. This can lead to pain that radiates from the lower back into the buttock and leg.
Sciatica may also be accompanied by tingling, numbness, or weakness, and symptoms sometimes develop several hours or even days after the activity itself.
When to see a back specialist
Dr Hussien El-Maghraby specialises in diagnosing and treating spinal conditions, including herniated discs, sciatica, and cervical nerve compression. Following a thorough assessment, he can recommend the most appropriate treatment.
If swimming or water sports have left you with ongoing neck, back, or leg pain, seeking specialist advice can help identify the underlying cause and ensure you receive the most appropriate care.
