The Integration ofElectronic Timing in
Speed TrainingChristopher Glaeser
Trends in Electronic Timing
• Transition from periodic testing to training
• Integration of timing into speed training
• Olympic and World Champion medalists, elite track teams
• High Schools and Colleges
• Ballistic events: Sprints, hurdles, horizontal jumps, pole vault
• Accels, fly-in sprints, hurdle splits, tempo runs
Benefits of Electronic Timing• Can increase arousal of athletes (speed workouts)
• Can motivate athletes (tempo runs)
• Immediate feedback can reinforce good technique (posture, relaxation, …)
• Provides Intervention (focus on quality over quantity)
• Increased accuracy of assessment (tempo and recovery)
• Coach can focus on other tasks (stand anywhere, watch anything)
Freelap Timing System
Benefits of Freelap
• Can time multiple athletes simultaneously
• Extremely versatile
• No tripods that require extra lanes
• Long battery life
• Rugged, water resistant, transmitters do not blow over
• Easy setup
• Accurate, wireless, expandable
• Lower cost compared to laser beams
• Small and compact for storage and travel
Freelap Watch
• Sprint belt for increased accuracy
• Store 765 splits organized into files
• Files are date and time stamped
• Data can be downloaded to Windows PC using IrDA USB dongle
Freelap Transmitters
• Tx Touch for block starts and three-point stance
• Tx Junior for splits
• Tx Touch is optional; Tx Junior can be used for fly-in starts
Versatility
• Example: 4x100 relay
• Relay leg selection
• Time 35 m fly (low hurdle marks) on the straight; repeat for turn
• Select legs based on performances in straight versus turn
• Do some speed work on the turn with baton
• Some athletes will hesitate for incoming athlete
• Time athlete in exchange zone without incoming athlete
• Compare exchange zone baseline with incoming athlete
Sprint Calculator
• Based on research by Bundle, Hoyt, WeyandHigh-speed running performance: a new approach to assessment and prediction
• Primary focus is practical coaching application
• Web-based implementation
• http://www.freelapusa.com/sprint-calculator
• Online User Guide
• Sample Data Set
Sprint Calculator (continued)
• ASR uses a short and long sprint to calculate all other distances
• Can be used for Intervention (quality versus quantity)
• ASR algorithm is based on fly-in sprints
• Calculator will convert block starts to fly-in sprints
• Can use times from track meets
• Can use any distance (e.g. high and low hurdle marks)
• Can predict new long distance
Sprint Calculator (continued)
• Work in Progress
• New features to be included with future releases
• Questions, comments, and feedback are welcomed
