Apart from one example (Artur Ashe), Type 2 diabetes is unheard of among the competitive sportiest. In contrast, Type 1 diabetes is prevalent among the sportiest participating in certain sports activities like driving bicycles, triathlon, etc. In contrast, the incidence of Type 1 diabetes among competitive sportiest in certain sports (competitive tennis players, etc.) is unheard of or almost non-existent.

1) On the one hand, Type 2 diabetes is unheard of among all competitive athletes, independent of sports activity type.
2) Type 1 diabetes is prevalent among competitive athletes of certain sports like cycling, triathlon, baseball etc. Still, it is unheard of or almost non-existent among competitive athletes in certain sports, like tennis, football, etc.
a) Competitive athletes with Type 1 diabetes get diagnosed after participating in sports activities for a while. ^{(Note! _{I didn’t find a single competitive athlete that was diagnosed with type 1 diabetes as a child.}}
b) The difference between the incidence of type 1 diabetes between certain sports activities is manifold.

An analysis of the prevalence of Type 1 diabetes and Type 2 diabetes among competitive athletes further points out that breathing biomechanics is the reason for the development of Type 1 diabetes.

Note! Certain sports and leisure activities like riding a bicycle promote mostly upper chest breathing, where the rest of the trunk becomes less active in the breathing process. In that case, the area of the trunk where the pancreas is located less expanding during inhalation and less constricting during exhalation.

People with Type 2 diabetes breathe mainly through the middle and lower parts of the trunk (belly breathing) due to their posture and musculoskeletal alignment (obese people) or habitual breathing biomechanics (non-obese people).
