Muscle Fatigue: Stiffening up after exercise can result from muscle fatigue as the body works hard during physical activity.
Lactic Acid Buildup: Accumulation of lactic acid in muscles contributes to stiffness, especially after intense or prolonged exercise.
Inflammation: Exercise-induced inflammation may cause stiffness as the body responds to the stress placed on muscles and joints.
Dehydration: Insufficient hydration can lead to muscle cramps and stiffness, emphasizing the importance of staying hydrated during and after exercise.
Cooling Down Too Quickly: Skipping a proper cooldown can lead to abrupt temperature changes, causing muscles to tighten up.
Overexertion: Pushing the body beyond its current fitness level can result in stiffness as muscles adapt to increased demands.
Poor Flexibility: Lack of flexibility or inadequate stretching before and after exercise can contribute to post-exercise stiffness.
Microscopic Muscle Damage: Intense exercise can cause microscopic damage to muscle fibers, triggering a protective response that manifests as stiffness during recovery.
