One exercise I like to incorporate in training is movement with eyes closed. This is a more advanced way to load up the vestibular system and decrease reliance on the visual system for ownership of movement. Alternating lunges with eyes closed are a great example of a simple, but not necessarily easy way to train… Continue reading The Vestibular System and Maintaining Position

Breaking Down Threshold Assessment: The Sensorimotor Components
Slicing the Pie Slicing the Pie involves a slight head tilt and re-orienting the head upright. The ability to perform this skill quickly while maintaining visual clarity requires the vestibular system. Specifically, the vestibulo-ocular reflex (VOR) in the roll plane. Kettlebell oblique sidebending is performed in this same plane, and through the addition of a… Continue reading Breaking Down Threshold Assessment: The Sensorimotor Components
Sensorimotor Skills
Blasts have been used in war for centuries. In fact, there is evidence of gunpowder bombs that date back to the Tang dynasty (circa 618-907 AD). [1] Though warfare and weapons have evolved since the Tang dynasty, blasts have remained a consistent variable of war. Sensorimotor skills are also a consistent variable of war, the… Continue reading Sensorimotor Skills
Astronaut Training for Mars: What Tactical Teams can Learn
Astronauts undergo rigorous training in preparation for spaceflight. One challenge that astronauts face in preparation for mission to Mars is what is called sensorimotor dysfunction. During spaceflight, astronauts experience prolonged zero gravity conditions, so the sensory systems responsible for movement – vestibular, visual, and proprioception – are sending altered information to the brain than when… Continue reading Astronaut Training for Mars: What Tactical Teams can Learn
Target Training: Breacher
I’ve been building out a 12-week program on Teambuildr that develops situational awareness capabilities specific to the demands Breachers face. No matter the position, situational awareness, target focus and acquisition, and ownership of movement can all be broken down to loading the visual, vestibular, and somatosensory systems. We can just load in different ways. Here… Continue reading Target Training: Breacher
Blasts and the Ear Canal
Primary blast injury is that due to the overpressure of the blast. Primary blast overpressure can travel through the abdomen, ears, eyes, nose, neck and mouth. The brain, lungs, intestines, eardrum, and peripheral vestibular system are particularly vulnerable to primary blast overpressure. Study by Sandlin et. al 2018 isolated blast overpressure waves to the… Continue reading Blasts and the Ear Canal
How I Progressively Load Vergence
Vergence is a vital situational awareness capability. It is the ability to keep a target in focus with forward/backward movements. Vergence requires your eyes to move in separate directions, like “cross-eyed” as a target is moving closer to you, as well as back away from you. Vergence is important to train in tactical athletes as… Continue reading How I Progressively Load Vergence
Keeping Target Focus with Forward/Backward Acceleration
A force with a forward or backward linear acceleration is unique as it will trigger a vergence response with the eyes. This means that the eyes are moving in opposite directions as they track a target moving closer or further from you. Placing the target on the ground in front of him, Ben then performs… Continue reading Keeping Target Focus with Forward/Backward Acceleration
Target Focus and the Vestibular System
In this video Ben is holding the camera while he walks and then transitions to a run. You’ll notice that as he walks we are able to maintain good focus of the gym, but as he transitions to a run we lose that ability to keep clear vision on the environment. But he didn’t lose… Continue reading Target Focus and the Vestibular System
Testosterone, Subconcussions, and Vestibular Function
Decreased testosterone levels are common after brain trauma. One study found testosterone suppression in 100% of men within 10 days after a mild traumatic brain injury. [1] “…administration of testosterone following injury to cranial neurons has been shown to upregulate the expression of neuroprotective genes…” [2] In other words, testosterone can help with brain health.… Continue reading Testosterone, Subconcussions, and Vestibular Function
