Effects of Different Long-Term Exercise Modalities on Tissue Stiffness.

Area of Science:

• Biomedical Engineering
• Exercise Physiology
• Tissue Mechanics

Background:

• Tissue stiffness is a crucial biological property.
• Pathologies, trauma, and interventions can modify tissue stiffness.
• Understanding exercise's role in tissue stiffness is vital for health.

Purpose of the Study:

• To investigate if specific exercise modalities induce distinct tissue stiffness adaptations.
• To review the effects of long-term exercise on muscular, connective, nerve, and arterial stiffness.
• To analyze exercise's impact on tissue stiffness in pathological populations.

Main Methods:

• Systematic literature search on PubMed, Scopus, and Web of Science.
• Inclusion of studies on long-term exercise interventions and tissue stiffness.
• Analysis of adaptations across different exercise types (resistance, aerobic, plyometric, stretching).

Main Results:

• Different exercise modalities result in varied tissue stiffness adaptations.
• Resistance, aerobic, plyometric training, and stretching all influence tissue stiffness.
• Exercise interventions normalized stiffness in pathological cohorts (e.g., tendinopathy, hypertension).

Conclusions:

• Exercise interventions demonstrably alter tissue stiffness.
• Specific exercise prescriptions should consider these stiffness adaptations.
• Further research is needed on diverse pathological populations with increased stiffness.
