A cohort study of risk factors for injuries in adolescent competitive tennis players

Title

Shoulder Management and Assessment Serving High performance (SMASH) – A cohort study of risk factors for injuries in adolescent competitive tennis players

Background

Tennis is one of the largest individual sports in Sweden. From an injury perspective, tennis is stressful for muscles, tendons and joints, and it is reasonable to assume that a balance between training load, competition and recovery is important.

Aim

We are investigating how our adolescent competitive tennis players train, compete and recover. In addition, the association to injuries in the shoulder and/or spine is investigated.

Method

During the 2018 spring-season, 301 tennis players, (176 boys and 125 girls) in the age 12-19 were included in the baseline screening (baseline questionnaire regarding training volume, previous injuries, years playing tennis and a clinical screening) to test isometric/eccentric strength, range of motion in the shoulder and range of motion in the thoracic spine. Weekly follow-up was then conducted for 52 weeks.

Significance

SMASH is a cohort study that may identify potential causal relationships between load and injury.

Research Principle
