Lumbar- and Cervicothoracic-Spine Loading During a Fast-Bowling Spell

Area of Science:

• Sports Biomechanics
• Injury Epidemiology
• Wearable Technology

Background:

• Cricket fast bowlers experience high rates of lumbar vertebrae injuries.
• Traditional biomechanical analysis lacks ecological validity for on-field assessment.
• GPS microtechnologies offer potential for measuring mechanical intensity during play.

Purpose of the Study:

• To evaluate GPS-mounted accelerometers for quantifying accumulated body load in cricket fast bowlers.
• To investigate how GPS unit placement affects load measurement and relates to injury data.

Main Methods:

• Field-based repeated measures study on a regulation cricket pitch.
• 10 injury-free male fast bowlers completed a 7-over spell.
• Two GPS units measured triaxial acceleration at cervicothoracic and lumbar spines.

Main Results:

• No significant increase in accumulated body load or triaxial contributions was found across the 7-over spell.
• The lumbar spine GPS unit recorded significantly higher load than the cervicothoracic unit across all triaxial planes.

Conclusions:

• Governing body guidelines for spell duration appear safe for this age group, showing no cumulative fatigue.
• Higher load at the lumbar spine supports epidemiological findings of injury incidence.
• GPS microtechnologies show promise for screening and monitoring players to prevent injuries.
