Tonic Contractions

Question

Tonic contractions
A) help maintain posture
B) cause an oxygen debt in the body
C) produce large amounts of lactic acid
D) both B and C

Accepted Answer

Tonic contractions help maintain posture by providing a constant low-level contraction in the muscles involved in standing or sitting upright. They do not typically cause an oxygen debt or produce large amounts of lactic acid, as they are not as intense or sustained as phasic contractions.
