Individuals with Down Syndrome are a diverse group, with varied skills and abilities. These swimmers are loving, social, and enjoy being in the water. Some of them can be a bit rigid, and resistant to new activities, and easily overwhelmed when activities are too hard. These individuals have low muscle tone, meaning their strength can be weak, their muscles can have a squishy feel and be less dense making them very buoyant in the water. Due to their core weakness, they have increased strain and overuse of their rectus abdominal muscle, which helps you do a straight sit up. Since this muscle is overused it may have a small split in it, (called a diastasis). This makes it very important to work on trunk rotation activities for oblique muscle strength, which helps improve this condition. They may posture with an increased arch in their lower back, and a slightly distended stomach, and may tend to lock their joints for stability.
