Lumbosacral Muscle Sensitivity & Pressure Pain Threshold After Kettlebell Swings

June 3, 2024 updated by: University of Central Florida

Tensiomyography and Pressure Algometry: Assessing the Effects of an Acute Bout of Kettlebell Swings on Muscle Sensitivity and Pressure Pain Threshold.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Kettlebell Swing Group
Participants will perform two-handed kettlebell swings
Other: Kettlebell Swing
Participants will perform two-handed kettlebell swings using the interval training protocol outlined in the study carried out by Jay et. al. (2011). The protocol calls for 30 seconds of work, followed by 30-60 seconds of rest for a total of 10 intervals. The mechanics of the kettlebell swing will follow those outlined in the study carried out by McGill et. al. (2012). All male participants will perform the intervention with a 16kg kettlebell and all female participants will perform the intervention with a 12kg kettlebell to assure reliability. The weight is higher than previous and similar study by Brandon et al to ensure measurable differences between experimental and comparison groups.
Active Comparator: Active Comparator Group
Participants will perform an isometric hold of a kettlebell for 30 seconds followed by 30 seconds of rest for a total of 10 intervals.
Other: Isometric Hold
Participants will perform an isometric hold of a kettlebell for 30 seconds followed by 30 seconds of rest for a total of 10 intervals. Participants will mimic initial kettlebell swing position by standing shoulder width apart with their back straight, and hips and knees flexed. Participants will be cued to squeeze their glutes and look straight ahead while they hold the weight for the 30 second interval. All male participants will perform the intervention with a 16kg kettlebell and all female participants will perform the intervention with a 12kg kettlebell to assure reliability.
Other: Control group
participants will be educated on the benefit of a kettlebell swing.
