Impact of swim training loads on shoulder musculoskeletal physical qualities (PhD Academy Award)

Abstract

What did I do?
I investigated the effects of swim training loads on physical qualities of the shoulder. The aim was to widen the knowledge of the interaction between training loads and potential risk factors for shoulder pain in competitive swimmers.

Why did I do it?
The aetiology of injuries is multifactorial including the dynamic interaction between multiple risk factors.1 Competitive swimmers are exposed to large training loads, swimming up to 14 000 m/day.2 Shoulder pain is the main reason for missed training,3 with up to 91% prevalence.3 Several modifiable risk factors for shoulder pain, relating to physical qualities of the shoulder (eg, range of motion (ROM), flexibility and strength), have been identified in swimmers.4 Although there is consensus that shoulder pain in swimmers is mainly caused by excessive training loads, research is lacking investigating its interaction with physical qualities of the shoulder.


How did I do it?
I performed four studies. Study 1 investigated the within-session and between-session (within-day and between-day) intrarater reliability of tests of shoulder function. The tests included shoulder rotation ROM, joint position sense (JPS), rotation isometric peak torque (figure 1), latissimus dorsi (LD) length, handgrip force (HGF) and combined elevation test (CET). Intraclass correlation coefficient (ICC), SE of measurement (SEM) and minimal detectable change (MDC 95%) were calculated for each test.
