“…For example, Nagano et al (2006) demonstrated that static stretching of plantar extensors for 3 min decreases postural stability in a quiet standing task. Further, Cornwell et al (2002) and Chaouachi et al (2008) showed that countermovement jump and 30-m sprint performance decreased after 3-min of static stretching.…”

“…Past findings demonstrated that shorter-duration (\3-min) static stretches decrease both postural stability (Nagano et al 2006) and isometric peak torque of the plantarflexors (Ryan et al 2008). On the other hand, static stretching shorter than 2-min produced conflicting results; decreased (Behm and Kibele 2007) and invariant jump performance (Cronin et al 2008).…”

Acute effects of static stretching on leg-spring behavior during hopping

Despite the fact that a stiffer leg spring is prerequisite for achieving a better performance during sports activities, effects of various types of warm-up on the leg stiffness is not well-known. The purpose of this study was to determine if static stretching influences the leg stiffness during two-legged hopping. Fourteen male subjects performed two-legged hopping at 2.2 Hz before and after a 3-min passive stretching of the triceps surae (dorsiflexion of 30°). Based on a spring-mass model, we calculated leg stiffness, which is defined as the ratio of maximal ground reaction force to maximum center of mass displacement at the middle of the stance phase. It was found that there was no significant difference in leg stiffness after passive static stretching. These results suggest that 3-min passive static stretching does not affect the leg-spring behavior and stiffness regulation during two-legged hopping. Finally, possible explanations for the invariant leg stiffness after the passive stretching are discussed.

“…The majority of these studies employed relatively moderate durations of static stretching ranging from 90 s to over 2 min for each muscle group. Whereas the mean percentage strength and force impairments ( ) and balance Nagano et al 2006). These static stretch-induced impairments can continue for 2 h. For example, Power et al (2004) had subjects stretch the quadriceps, hamstrings and PF with two different stretches of three repetitions each for 45 s (270 s/muscle).…”

A review of the acute effects of static and dynamic stretching on performance

An objective of a warm-up prior to an athletic event is to optimize performance. Warm-ups are typically composed of a submaximal aerobic activity, stretching and a sport-specific activity. The stretching portion traditionally incorporated static stretching. However, there are a myriad of studies demonstrating static stretch-induced performance impairments. More recently, there are a substantial number of articles with no detrimental effects associated with prior static stretching. The lack of impairment may be related to a number of factors. These include static stretching that is of short duration (<90 s total) with a stretch intensity less than the point of discomfort. Other factors include the type of performance test measured and implemented on an elite athletic or trained middle aged population. Static stretching may actually provide benefits in some cases such as slower velocity eccentric contractions, and contractions of a more prolonged duration or stretch-shortening cycle. Dynamic stretching has been shown to either have no effect or may augment subsequent performance, especially if the duration of the dynamic stretching is prolonged. Static stretching used in a separate training session can provide health related range of motion benefits. Generally, a warm-up to minimize impairments and enhance performance should be composed of a submaximal intensity aerobic activity followed by large amplitude dynamic stretching and then completed with sport-specific dynamic activities. Sports that necessitate a high degree of static flexibility should use short duration static stretches with lower intensity stretches in a trained population to minimize the possibilities of impairments.

“…Blurring of proprioceptive input from leg muscles, as produced by vibration during stance, leads to post-vibration instability (Wierzbicka et al 1998). Postural after-eVects also follow a period of stance or stepping on an inclined surface with eyes closed, and induce body leaning, thereby producing a body-to-surface relationship as if subjects still stood on the incline (Kluzik et al 2005(Kluzik et al , 2007Nagano et al 2006). Long-lasting body leaning also follows neck muscle isometric contractions, likely connected to a change in postural reference resulting from increased proprioceptive inXow (Duclos et al 2004).…”

Quiet stance control is affected by prior treadmill but not overground locomotion

Treadmill locomotion is different with respect to overground walking and may require an adapted control mode. The relevant neural computational effort may produce lasting effects encroaching upon the performance of a subsequent postural task. The hypothesis of the present study was that, contrary to overground walking, treadmill walking has effects on quiet stance variables, in the assumption that the imposed locomotor activity is more critical to stance control than natural walking. Nine young subjects performed three different walking sessions: treadmill with eyes closed, treadmill with eyes open, overground walking with eyes open. Body sway area and sway path and the position of the centre of foot pressure during stance were recorded by a dynamometric platform under control, post-walking and post-recovery conditions, alternatively with eyes closed and eyes open. At variance with overground walking, treadmill locomotion produced an effect on body orientation in space during the subsequent stance trials. This consisted in a forward inclination of the body, not accompanied by increased body sway, lasting for a few minutes. Presence or absence of vision during treadmill locomotion did not induce differences in the amplitude or time-course of the post-effect. We argue that body inclination would be the consequence of a change in the postural reference produced by a message arising from treadmill locomotion itself, possibly connected to particularities in the control mode of this type of walking.
