Mechanical loading, particularly cyclic stretch, produces engineered cardiac tissues with higher maturity in terms of twitch force, elastic modulus, sarcomere length and molecular signature, when comparing to static stretch or non-stretched controls.
2. How long do I need to hold a static stretch?
Yang, H. et al. Dynamic myofibrillar remodeling in live cardiomyocytes under static stretch.
How long you hold a static stretch helps dictate how many repetitions (reps) of the stretch you should do.
Although opinion varies on this, the ACSM recommends holding a static stretch for 10 to 30 seconds.
The ACSM says 60 seconds of cumulative time per static stretch is optimal and recommends doing two to four reps to achieve this total time.
Does static stretch positioning combined with simultaneous neuromuscular electrical stimulation (NMES) in the subacute phase after stroke have beneficial effects on basic arm body functions and activities?
The undamped, finite amplitude horizontal motion of a load supported symmetrically between identical incompressible, isotropic hyperelastic springs, each subjected to an initial finite uniaxial static stretch, is formulated in general terms.
Study Design: Freshly isolated myometrial smooth muscle cells (from virgin rats) were plated on flexible culture plates that were coated with either collagen I, laminin, elastin, or pronectin and were subjected to a static stretch with a computerized strain unit.
Static stretch led to significant increases (P < 0.01) in E app) beginning at 2 days.
Results show that AQP1 expression significantly increased 2-fold with 10% static stretch and 3.5-fold with 20% static stretch at 8h (n=4, p<0.05) and 24h (n=6, p<0.05).
