The Delta app is suitable for modern iOS-operated digital devices (e.g. smartphone, tablet). Data collected by means of a Movesense HR2 sensor are eventually used for analyzing and visualizing external workload and internal workload by the DeltaDashboard application of Delta Sport Innovation, being especially suited for sports characterized by physically challenging and demanding complex repetitive upper and lower extremity movements with constant postural variations, asking for short bursts of movement, sudden sharp changes of direction, lunges, sprints, reaches, retrievals, jumps and powerful strokes. Think of sports like badminton, tennis, padel, squash, beach volleyball, 3×3 basketball and more.
