Remedial Loading Programs: Stretch Training
/Preliminary findings suggest stretch training is a viable way to stimulate architectural adaptation. Changes in the passive elastic properties and range of motion induced by stretch training is due to both neurological increases in stretch tolerance and changes in passive properties of muscle.
These changes induced by stretch training, may have clinical implications for injury prevention and rehabilitation programs.
Stretching for Overhead Athletes
A number of papers have demonstrated the effects of stretch training on tissue stiffness, shoulder internal rotation and horizontal adduction.
4 weeks of soft tissue mobilization had an affect on tissue stiffness, shoulder internal rotation and horizontal adduction in baseball players with posterior shoulder tightness (Yamauchi et al. 2016).
Modified cross body stretch and modified sleeper stretch leads to decreased the stiffness of the teres minor and infraspinatus (Umehara et al. 2017)
Instrumented manual therapy with self-stretching significantly reduces ROM risk factors in baseball players with motion deficits (Bailey et al. 2017)
A 4-week treatment program of manual therapy or dry needling demonstrated a significant improvement in pain pressure threshold, muscle elasticity, and stiffness of neck and shoulder muscles (De Meulemeester et al. 2017).
Hamstring Stretch Training
Preliminary findings suggest nordic hamstring exercises and stretch training are a viable way to stimulate architectural adaptation. For a more indepth looks at theses changes you may want to check out Greg Lehmans recent post on hamstring stretching - or these recent studies:
In one study 8 weeks of high-intensity stretch training on biceps femoris induced architectural adaptation and improved range of motion (Freitas et al. 2015).
4 weeks of stretching training of the hamstring group (Muanjai et al. 2017).
Nordic Hamstring Extension (Alonso-Fernandez et al. 2017, Bourne et al. 2017)
Plantar Flexor Stretching
For a more indepth looks at theses changes you may want to check out these recent studies:
6 weeks of loaded stretch training of the plantar flexors resulted in hypertrophic like adaptations of the gastrocnemius (Simpson et al. 2017)
3 weeks of twice daily stretch training (4 × 30 s) lead to an increase in dorsiflexion range of motion (ROM) a 28% increase in passive joint moment (Blazevich et al. 2014).
4-week static stretch training program changes the flexibility of the gastrocnemius muscle tendon unit (Nakamura et al. 2012)
5 min of static stretching was shown to decrease shear elastic modulus in both young and elderly women (Nakamura et al. 2017)
