Project Description

Exercise device for training in a pool. The benefits of exercising in the pool have long been established.  However, there have been relatively few innovations that encourage pool activity. While swimming laps or playing water polo or other games are both challenging and aerobic, persons with limited swimming skills may be interested in other activities.  We propose a buoyant ball for enhancing activity in the pool.  Actually, the buoyant ball is more likely to be neutrally buoyant.  It would remain submerged most of the time and be capable of being dribbled across the pool similar to kicking a soccer ball across a field. Additionally, the ball would be capable of realistically estimating the amount of energy used (calories burned, etc.) during use.

Design Constraints

The device should be of a size and weight that can be easily used in a swimming pool. The device should withstand adult kicks and should realistically estimate the energy used during a period of activity. Buoyancy requirements must be determined and thus are not specified. It must be user friendly and operable by elderly persons.

Expected Performance Outcomes

This device is expected to be capable long-term use in a aqueous environment. It must withstand 1 million cycles of kicking, and it must be at least 90% accurate in estimating the total energy used during active use.

Group Size and Expertise Required

2-3 persons are expected to work on this project. The required expertise includes: Mechanical Design and CAD, Signal detection, analysis, and post processing, Electronics and computer hardware integration, knowledge of human anatomy and physiology, and Knowledge of materials science and biomechanics.
