Bring muscle-activation data into return-to-play decisions

BioSensr tracks muscle activation during standardised isometric hamstring holds and compares results against athlete-specific baselines. Coaches and performance professionals can review activation changes across sessions to complement their existing assessments.

Sports teams use GPS, force platforms, and dynamometry to measure workload and output. BioSensr adds muscle-specific surface electromyography (sEMG) to quantify muscle activation during a standardised isometric hamstring hold. The platform tracks these activation measurements over time, comparing each session against athlete-specific baselines.

Muscle-specific data for return-to-play decisions

During peak training, this elite beach sprinter’s right biceps femoris muscle activation was monitored using BioSensr to track recovery trends and help manage training loads. Percentages show measurements relative to the athlete's baseline. BioSensr displays numerical differences and categorises changes as Improving, Stable, or Declining. These metrics describe data trends only and do not indicate a medical condition or determine readiness to play.

Research and field evaluation
