Exploring the Importance of Planes of Motion

Can understanding the planes of motion help individuals adjust fitness training to maximize fitness for physical and sports performance and reduce the risk of injury?

Planes of Motion

The body’s planes of motion are the sagittal, frontal, and transverse planes, which divide it into left and right, front and back, and top and bottom halves. The body moves in different dimensions during daily work, house chores, and physical activity/exercises. The movements in each plane correspond to forward/backward, side-to-side, and rotational motions. Think of each plane as an imaginary line or a pane of glass that divides the body into opposing segments when standing in the anatomical position. (National Academy of Sports Medicine, 2024)

  • Sagittal plane -Divides the body into right and left sides.
  • Frontal plane – Divides the body into front and back.
  • Transverse plane – Divides the body into top and bottom sections.

To determine the plane of motion of a particular movement, consider how the movement would interact with the imaginary lines or plates. When a movement runs parallel to the imaginary line, the movement is occurring in that plane of motion. For example, when going upstairs, the forward and upward movement at the hip, knee, and ankle occurs primarily in the sagittal plane because that movement runs parallel to the imaginary line that divides the body into right and left sides. Frontal plane movements occur while you walk up the stairs and reach for the handrail. The movement is in the frontal plane because the lateral hand reach runs parallel to the line, dissecting the body into front and back sections. If you turn around to look behind, the rotational movement occurs in the transverse plane because your upper torso runs parallel to the line, dissecting the body into an upper and lower section. Individual movements at any joint in the body can occur in a single plane or multiple planes. Complex movements usually happen in several planes of motion concurrently.

Sagittal Plane

Movement in the sagittal plane generally happens in front or behind. This is the most familiar plane of motion because many typical day-to-day activities happen within arm’s reach in front. Walking, texting, or computer work involves movement primarily in the sagittal plane.  Several eating mechanics occur in the sagittal plane. Movements include:

  • Flexion – A bending movement that decreases the angle at a joint
  • Extension – An extending movement that increases the angle at a joint
  • Hyperextension – Extending the angle at a joint beyond neutral
  • Dorsiflexion – Bending at the ankle so the top of the foot moves toward the shin
  • Plantarflexion – Pushing the foot down and away from the body

Many strength-training exercises in the sagittal plane include biceps curls, forward or reverse lunges, squats, vertical jumping, running, downward dog, and yoga chair poses.

Frontal Plane

The frontal plane divides the body into front/anterior and back/posterior sections. Frontal plane movements are lateral or side-to-side and include:

  • Abduction – Moving the body or a limb laterally and away from the body’s midline.
  • Adduction – Moving the body or a limb towards the body’s midline.
  • Elevation – Moving the shoulder blades up.
  • Depression – Moving the shoulder blades down.
  • Eversion – Rolling the foot towards the inside/medial side.
  • Inversion – Rolling the foot towards the outside/lateral side.

Frontal plane movements are less common than sagittal movements. For example, individuals walk forward more than side to side or reach for something in front rather than directly to the side. Frontal plane movements in fitness include side lunges, lateral shoulder raises, and side shuffles, and in yoga poses, standing side bends and the triangle.

Transverse Plane

The transverse plane divides the body into upper/superior and lower/inferior sections. Transverse plane movements generally involve rotation. Movement in this plane is less common. Exercise injuries most often occur during transverse/rotational movements. (National Academy of Sports Medicine, 2024) Movements include:

  • Rotation – Moving the torso or a limb around its vertical axis.
  • Pronation – Rotating the forearm or foot to a palm-side or foot-side down position.
  • Supination – Rotating the forearm or foot to a palm-side or foot-side-up position.
  • Horizontal Abduction – Moving the upper arm away from the body’s midline when elevated to 90 degrees.
  • Horizontal Adduction – Moving the upper arm towards the body’s midline when elevated to 90 degrees.

Typical everyday activities in the frontal plane include turning the head to look behind or turning a doorknob. Exercises in the transverse plane include hitting a golf ball, swinging a baseball bat, or performing a seated twist.

Training Within the Planes of Motion Benefits

Training in all three planes can help with movement in several ways, providing greater ease in life and sports.

Prepares Body for Daily Tasks

Many traditional strength-training programs focus on training one muscle at a time, often in a single plane of motion. For example, weight lifters might do bicep curls to primarily work the biceps in the sagittal plane, a chest fly exercise to primarily work the pectoral muscles in the transverse plane, or lateral raises to work the shoulders in the frontal plane. However, compound exercises have recently become much more common. Compound movements allow individuals to train several muscle groups simultaneously and in different planes of motion.

In this way, training activities mimic daily living activities. For example, individuals often lift several heavy bags of groceries and turn to open the car or trunk, involving both sagittal and transverse movement. Preparing the body for complex activities with compound exercises allows individuals to perform them more easily throughout the day.

Prepares Body for Sports and Physical Activities

Complex multi-planar movements help prepare for safe and effective physical activity and sports performance (National Academy of Sports Medicine, 2024). Researchers and experts understand that many physical and athletic activities require the body to move in different directions, often quickly and under high stress. Several studies have found that anterior cruciate ligament/ACL injuries are more likely to occur during multi-planar rather than single-planar movements. (Quatman C. E., Quatman-Yates C. C., & Hewett T. E. 2010) Training the body to perform multi-planar movements safely and effectively through exercise can help reduce the risk of injury during daily activities or stressful athletic competitions.

Encourages Variation For Full Body Strengthening

Individuals tend to fall into certain movement patterns, such as repeatedly performing the same fitness activity or exercises. This can cause them to have a favorite plane of motion. One way to break away from the same routine is to include movement from all planes of motion. For example, many abdominal workout machines help train in multiple planes of motion, challenging your body to move in different ways. Dumbbells, kettlebells, TRX straps, and bands allow individuals to move joints freely in various planes of motion and work several muscles.

Runners train primarily in the sagittal plane, even if they cross-train by swimming, cycling, or using cardio machines. For this reason, trainers and coaches often recommend doing some form of yoga or weight training that allows them to move their joints in different ways, including lateral movements or rotation. Even flexibility training should incorporate all three planes of motion. For example, walkers might choose to do a simple calf or hamstring stretch at the end of their workout but may also benefit from a seated spine rotation or a lying hip stretch.

Mastering the Hip Hinge: A Key Movement for Back Health

Can performing the hip hinge exercise movement help individuals with lower back pain?

Hip Hinge Exercise

A hip hinge is a controlled movement that involves bending forward from the hips while keeping the spine neutral. The thoracic, lumbar, and pelvis stay neutral while bending forward. The movement comes from the hips, preventing the thoracic and lumbar spine from flexing or rounding. It is a fundamental movement that helps prevent back injuries and strengthens the glutes. It’s used in everyday activities, like picking up objects and sitting down.

The hip hinge exercise targets the posterior chain or back muscles, including the lower back, the glutes, and the hamstrings. It also strengthens the core or abdominal muscles to assist in the movement. When the body hinges at the hips, the bend occurs at the hips, and the spine stays neutral. When the lower back hinges or bends, this causes pain and reduces the range of motion.

Performing the Movement

A wooden dowel, broom handle, or PVC pipe can be used as a guide to help achieve the proper positioning and learn the correct form. Place the dowel or pipe vertically on your back, anchoring it to the head, shoulder blades, and tailbone.

Grasp one end with your right hand in the natural curve of your neck and the other with your left hand in the small of your back. Ensure the dowel touches the back of your head, upper back, and the area where the lower back meets the sacrum. To perform the hip hinge:

  • Stand with your feet shoulder-width apart
  • Shift your weight to your heels and
  • Push your hips back while hinging your torso forward
  • Keep your chest open and back flat
  • Slightly bend your knees
  • Visualize sticking the butt out
  • The dowel should not lose contact with the three points as you hinge. If it does, the movement is incorrect.
  • Lower your torso until it’s midway between vertical and parallel to the floor.
  • Pause when your torso is about 45 degrees
  • Keep a slight bend in your knees during the downward and upward phases.
  • Reverse the movement by contracting your glutes and pushing your hips forward and upward to return to the starting position.
  • Repeat

Benefits

The hip hinge is a fundamental movement pattern that helps the body perform essential tasks such as bending over and picking things up without worry of pain or injury. It’s also required in strength training exercises like the deadlift, kettlebell swing, power clean, and more. The exercise can help strengthen the core, reduce back pain, improve balance, and improve flexion, extension, and trunk rotation. (Michaud F. et al., 2021) Stronger core muscles can increase fitness and athletic performance. (Clark D. R. et al., 2018)

Variations

It is a challenging movement that requires plenty of practice. Individuals who can’t perform it correctly after a few tries may need to modify the movement.

Wall Variation

  • Using a wall as a guide is an easy way to make the movement easier.
  • To do this, stand with your back to a wall, about three inches away.
  • Start hinging at the hips by sticking your butt out touching the wall.
  • Keep a neutral spine and a flat back.

Once you can do this several times, try stepping out another inch or two and perform the same modified motion. Stick with this until you are away from the wall and can do a full hinge without the wall.

With A Kettlebell

  • Once you master the basic hinge, you can elevate it using a kettlebell to make this move more difficult.
  • Start with the kettlebell swing exercise and progress to more challenging moves with the kettlebell.

Common Mistakes

Be aware of common mistakes to keep the move effective and reduce the risk of injury.

Treating the Move Like a Squat

  • The hip hinge is not the same as a squat.
  • This is a common misconception. When squatting, the knee joint determines the movement pattern.
  • But when hip hinging, the movement starts at the hips.

Not Engaging the Core Muscles

  • This exercise requires core engagement throughout the entire movement.
  • If these muscles relax, there is an increased risk of dipping the hips during the hinge, which can cause the lower back to dip and cause pain.

Using the Lower Back

  • Bending or hinging with the lower back rather than letting the hips generate the movement.
  • Using the wall as a guide can help reduce and eliminate excessive bending at the waist.

Lost Dowel Contact 

  • If the dowel loses contact with one or more set-up positions on the back, the hinge is not being executed correctly.
  • If your head loses contact with the dowel, the neck is flexing too far forward.
  • If you lose contact with the sacrum or lower back area, the spine is flexing too much.
  • If you lose contact with the mid-back, the knees are bending rather than the hips.

Safety

Stop and check your form if you feel back pain during any part of the movement. The movement may need to be modified further or decrease how far the hinge is at the hips. If the pain continues, discontinue the exercise and talk with a doctor or a physical therapist before reattempting the exercise. The dowel is a great tool to help maintain a neutral spine. If you cannot perform the hip hinge while keeping the dowel in contact with the body, you might benefit from working with a personal trainer or physical therapist who can walk you through the steps with the correct form.

Sleeping with Lower Back Pain and Sciatica: Finding Relief 

Sleeping with lower back pain and sciatica can be difficult and frustrating. What are ways to get more comfortable sleep?

Sleeping With Lower Back Pain and Sciatica

Various factors can affect sleeping with lower back pain and sciatica, including age, injury and medical history, the mattress (e.g., soft vs. firm mattress), and sleep positions. Unfortunately, there’s no one-cure-all solution for this problem, and depending on the underlying cause/s, they can worsen the pain and cause sleep problems. For example, if a herniated disc places added pressure on the nerves in the lower back, twisting the spine can worsen the lower back pain, and sleeping in a fetal position can exacerbate the nerve pain. (UCF Health, N.D.)

Lower-Back Pain

Low-back pain can be activity-related, intermittent, or constant. (American Association of Neurological Surgeons, 2024) For some, it only occurs occasionally, such as when performing specific movements. For others, it can be excruciating, chronic, and disabling. Low-back pain is unique for everybody and can differ depending on the cause. Some low-back pain symptom descriptions include (Förster M. et al., 2013)

  • Aching pain deep in the back
  • Shooting pain flare-ups
  • Pain caused by slight pressure
  • Burning
  • Tingling

Sciatica Not Present

For some, low-back pain may be confined to a specific area known as axial back pain. (Förster M. et al., 2013) The pain may be felt in a band along the lower back and does not radiate down the legs or anywhere else.

Sciatica Present

Low-back pain with sciatica pain that radiates from the lower back or hip down the leg is the most common symptom of lumbar radiculopathy (compression of spinal nerve roots). (North American Spine Society, 2020) Sciatica symptoms include: (American Academy of Orthopaedic Surgeons, 2021)

  • Shooting pain from the lower back down the leg
  • Feeling like a bad leg cramp
  • Leg weakness
  • Sensory changes radiating down the leg – numbness, burning, and or tingling

Sleep Tools

Consider changing the mattress to improve sleeping with lower back pain and sciatica. For the best spinal support, choose a medium to firm mattress. Pillows, wedges, and other tools can also help improve sleep. (UCF Health, N.D.) It is recommended that individuals who sleep on their backs place a small pillow under their knees to reduce pressure on their lower backs. For those who sleep on their side, placing a pillow between the knees can keep the spine in a neutral/straight position. To relieve lower back pain, consider sleeping in a reclined, angled position with the head and shoulders higher than the hips. This can be accomplished with an adjustable bed or a wedge to prop the body in a regular bed.

Back Sleeping

Easing back pain while sleeping involves maintaining the body in a neutral or straight position. Extending the muscles, tendons, and ligaments too far in any one direction while sleeping with lower back pain and sciatica can cause stiffness, muscle spasms, and pain. Sleeping on the back puts the spine in neutral alignment with the least stress on the neck and back. It evenly distributes body weight to avoid exerting pressure on the joints and prevent backaches. In addition, a supine position allows outstretched ligaments to shrink and recover to their normal positions. (Keck Medicine of USC, 2019)

Chiropractic Assessment

Chiropractic care aims to help individuals improve movement with less pain due to condition, after injury, or surgery. A chiropractic physical therapy team may be best for individuals with acute back, neck, and musculoskeletal pain and discomfort symptoms. A chiropractor can quickly assess your condition and develop a customized treatment plan to expedite pain relief and improve mobility. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to build optimal health and wellness solutions. We focus on what works for you to relieve pain, restore function, prevent injury, and help mitigate issues through adjustments that help the body realign itself.
