Final answer:
True, an impinged shoulder affects overhead pressing movements because rotator cuff injuries or conditions like adhesive capsulitis (frozen shoulder) lead to reduced shoulder mobility and pain during these activities. (option a)
Step-by-step explanation:
Impinged shoulder indeed affects overhead pressing movements, and thus the correct answer to the question is a) True. The rotator cuff, which consists of the tendons of the deep subscapularis, supraspinatus, infraspinatus, and teres minor, is critical for shoulder stability during overhead activities. Repetitive overhead motions, such as those seen in throwing sports, can lead to rotator cuff injuries, causing inflammation, impingement, or tearing of the tendons. This can greatly compromise shoulder function and cause pain during overhead pressing movements. Additionally, conditions like adhesive capsulitis (frozen shoulder), where scar tissue leads to reduced shoulder mobility, can also impair the ability to perform such exercises.
The statement "Impinged shoulder affects overhead pressing movements" is true. Individuals with shoulder impingement should exercise caution and, if necessary, consult with a healthcare professional or a qualified fitness trainer to modify their exercise routine to avoid exacerbating shoulder issues.
