The cadets also played sports during their time in Oshkosh. Cadets could play informal pick-up games during their recreation hour held at the end of afternoon classes. Cadets played a wide variety of sports, including volleyball, touch football, horseshoes, and tennis.
The Oshkosh Recreation Department assisted the college and detachment in securing athletic fields, developing schedules, and finding referees. A 10-team softball league was established in summer, two 8-team volleyball leagues were formed in fall, and winter brought on three 8-team basketball leagues.
Although the detachment lacked regular access to a swimming pool, Captain Carson Conrad, Deputy Director of Physical Training of the Western Flying Command, had "high regard for the manner in which it [the physical training program] was administered" and the OSTC program was rated as "superior."
