Static stretching

Static Stretching

Stretching has been performed for thousands of years, commonly before warriors would go into battle (Chaabene et al., 2019). These days the practice of stretching is more commonly used in the athletic, fitness, rehabilitation and recreation settings (Chaabene et al., 2019). Stretching these days is broken down into static, dynamic, ballistic, proprioceptive neuromuscular facilitation (Chaabene et al., 2019). Although in this post, static stretching is going to be the focus. Static stretching involves controlled continuous movement to the end range-of-motion (ROM) of a single joint or multiple joints by either actively contracting the agonist muscles or by using external forces such as gravity, partner, stretching aids (Behm et al., 2016). Recently some social media influencers have asserted that static stretching is bad for performance and strength. According to literature findings from Bacurau et al., 2009, Nelson et al., 2005 & Young & Elliott, 2001, static stretching caused a decrease muscle-force production capacity. Muscle force production is depended on the output of the cross-bridge form during an isometric contraction (Fitts et al., 1991). A easier way to understand this is.

Reynolds (2022) “Strength is the ability to produce force against an external resistance” therefore “strength is muscle force production” (Barbell logic, 2022)

The findings of these study alone, would support these influences narrative. Furthermore, there is a large body of scientific evidence has recommended not to use StS immediately before the performance of strength- and power-related activities (McHugh & Cosgrave, 2010; Peck et al., 2014; Simic et al., 2013).

Although, two big literature review findings suggested less than 60 seconds of static stretching did not have impact on strength like static stretching of greater than 60 seconds (Behm et al., 2016,Kay & Blazevich 2012). Palmer et al., (2019) study also support these findings. Furthermore, recent literature would suggest that there is very little impact static stretching on muscle force when using less than 60 seconds. (Chaabene et al., 2019, Cramer et al., 2007). Contradicting findings from the literature. However, the significant differences is in the methodology section, where previous studies focused on longer durations of stretching. Therefore it is the interruption of the findings. The main weakness of social media post is that it has to look good and pull you in, thus caution must be applied when reading these posts. Despite this, a recent study suggested 20 seconds of static stretching could help improve range of movement and with limited impact of strength (Sato et al., 2020). Although this was only a limited population study, this does leave food for thought when stretching.

Take away stretch.

The 90/90 hip stretch, can be a great move to do when you are wanting to feel freedom into the hip area. How the 90/90 hip stretch works is that it has one hip into internal rotation and the opposite hip into external rotation. As shown in the youtube link below. Stretch both sides and enjoy.
