8. Listany7ofthe10generalphysicalskills.
○ Cardiovascular/respiratoryendurance—Theabilityofbodysystemstogather,process
anddeliveroxygen.
○ Stamina(muscularendurance)—Theabilityofthemusclestoworkoverlongperiods
againstsubmaximalloads.
○ Strength—Theabilityofamuscularunitorcombinationofmuscularunitstoapply
force.(Note:Oftenstatedasmaximalforce.)
○ Flexibility—Theabilitytooptimizetherangeofmotionatagivenjoint.
○ Power—Theabilityofamuscularunitorcombinationofmuscularunitstoapply
maximumforceinminimumtime.(Note:Powercanbethoughtofasforcexvelocity
orastherateofdoingwork.)
