Brief summary: The primary purpose of the study is to assess the muscle contractility and sensitivity of lumbar erector spinae, biceps femoris, and gluteus maximus short-term response to Tabata kettlebell swing protocol.

Detailed description: While there are many studies that combine resistance exercise with TMG, there are no studies that combine TMG or pressure algometry with an isometric hold of a kettlebell. This will be the first study that will observe the relationship between these specific variable

It has also been noted that kettlebell swings have an acute effect on muscle sensitivity. A study conducted by Hanney et al. (2017) demonstrated that there was an increase in the mean lumbosacral muscle pain pressure threshold across three locations measured.

Research by Hanney et al. is also the only article that has combined kettlebell swings and pressure algometry. As mentioned earlier, these researchers measured the effects of kettlebell swings on pressure pain threshold in the quadratus lumborum, paravertebral muscles, and the piriformis after an acute bout of 2 handed kettle-bell swings. Compared to a control group, the kettlebell swing group had significantly higher pressure pain thresholds for all three of the testing sites.

Researchers believe this may be due to an increased hyperemia-state post exercise, where the increased blood flow and vasodilation flushes out muscle metabolites. Clearing of these metabolites which normally activate chemo-nociceptive free nerve endings, are theorized to decrease pain sensitivity. This post-exercise hyperemia, leading to decreased pressure pain thresholds, may be directly related to the changes in contractility of the muscle after resistive exercise.
