  • A September 9, 2026 study in Frontiers in Bioengineering and Biotechnology found that 240 young adults changed their trunk, hip, and ankle position at ground contact when a mental-math task was added to jump-landing.
  • Trunk flexion range of motion and trunk flexion angle at contact were among the top five features separating distracted landings from focused ones in that study's analysis.
  • A January 2026 pilot study of 20 athletes found those with prior ACL reconstruction scored 3.8% to 14.1% lower on combined cognitive-and-movement testing than uninjured peers.
  • A May 2026 systematic review of 8 randomized trials (224 patients) found dual-task training matches or outperforms single-task training for ACL reconstruction, ankle instability, and jump-landing mechanics.
  • P.O.W. PT, led by Dr. Josh Lombardi DPT, CSCS, layers dual-task drills into late-stage rehab and return-to-sport programming once baseline movement quality is established.

The Hook

Dual-task training — practicing movement while your brain is also busy with a mental task — just picked up new scientific backing. On September 9, 2026, researchers publishing in Frontiers in Bioengineering and Biotechnology reported that when 240 physically active young adults did simple mental math while jump-landing, their trunk, hip, and ankle positions at the moment of ground contact shifted in measurable, predictable ways compared to landings with full attention. That single finding puts hard numbers behind something our physical therapy team at P.O.W. has coached for years: an athlete's landing mechanics aren't just a strength or flexibility problem, they're a brain-and-body problem. If a distracted mind changes how you land, then rehab that only trains the body while attention is fully focused may be missing half the job.

Short answer:

Dual-task training pairs a physical movement, like a landing, cut, or hop, with a mental challenge, such as math, reaction cues, or decision-making, to train the body to move safely even when attention is divided. A September 2026 study found landing mechanics change measurably under mental distraction, and dual-task training is how physical therapists prepare athletes for that real-world demand before full return to sport.

The Science

Landing mechanics change when the brain is asked to do two things at once because attention is a limited resource, not an unlimited one. Controlling a knee, hip, and trunk position during a jump-landing normally draws on a mix of automatic reflexes and conscious motor control. When a cognitive task, like solving a math problem or scanning the field for a teammate, competes for the same attentional resources, the brain shifts control toward faster, less deliberate movement strategies.

In the September 2026 Frontiers study, that shift showed up as changes in base-of-support width, hip flexion angle, ankle position, and trunk flexion at the instant of ground contact, the same variables clinicians already watch closely in ACL-injury-prevention screening. The authors were careful to note their model distinguished distracted landings from focused ones, not injured athletes from healthy ones, so these findings describe a mechanism, not a proven injury-risk score.

Still, the direction of the evidence lines up with earlier work: a January 2026 pilot study found athletes with prior ACL reconstruction had measurably worse combined cognitive-motor performance than uninjured controls (a 3.8%–14.1% gap), and a May 2026 systematic review of eight randomized trials found dual-task training performs as well as, or better than, single-task training for postural control after ACL reconstruction and for jump-landing mechanics in chronic ankle instability. Sport itself is rarely single-task, athletes cut, land, and decelerate while reading a defender, tracking a ball, or reacting to a teammate's call. Training the body to move well only when attention is fully available leaves a gap between the clinic and the field.

The Solution at P.O.W.

At P.O.W. PT, Dr. Josh Lombardi, DPT, CSCS, treats dual-task training as a layer added on top of, and not a substitute for, solid fundamentals. The sequence typically looks like this: first, we build clean, well-controlled landing and cutting mechanics with the athlete's full attention on the task. Once that baseline movement quality is consistent, we begin adding a second demand, a verbal math problem, a color or number cue that changes the landing target, a reaction-light drill, or a sport-specific scanning task, while the athlete performs the same movement.
The goal isn't to trick the athlete; it's to rehearse the exact situation they'll face in competition, where the brain is never devoted 100% to footwork. This approach fits naturally into return-to-sport programming after ACL reconstruction, ankle ligament surgery, or any lower-extremity injury where an athlete needs to prove they can move safely under game-like mental load, not just in a quiet gym. Because the current evidence (including the September 2026 study) shows dual-task performance and single-task performance don't always move together, we track both separately rather than assuming clean mechanics on a simple hop test mean an athlete is ready for the chaos of a real game.

Frequently Asked Questions

What is dual-task training in physical therapy?

Dual-task training is any rehab exercise that combines a physical movement, like landing, hopping, or cutting, with a mental task, such as math, verbal recall, or reacting to a visual or auditory cue. The idea is to train the nervous system to control movement even when attention is split, which mirrors real sport and daily life far more closely than movement practiced in silence with full focus.

Does mental distraction really change how you land?

Yes. A September 2026 study of 240 physically active adults found trunk, hip, and ankle position at ground contact shifted in measurable, consistent ways when participants solved simple math problems during a jump-landing task. The researchers were clear that this shows a change in movement pattern under distraction, not a proven injury diagnosis, but the pattern is worth paying attention to.

Can dual-task training help prevent ACL injuries?

It may help, though the direct injury-prevention evidence is still developing. A May 2026 systematic review of eight randomized trials found dual-task training matches or beats single-task training for postural control after ACL reconstruction and for landing mechanics in chronic ankle instability, which supports adding it to a well-rounded prevention and rehab program rather than relying on it alone.

When should dual-task training start in ACL rehab?

Dual-task training is typically introduced in the later strengthening and return-to-sport phases, after an athlete has already rebuilt strength, range of motion, and clean single-task landing mechanics. Adding cognitive load too early, before basic movement control is reliable, can reinforce poor patterns instead of correcting them.

Is dual-task training only for athletes recovering from an injury?

No. While it's especially useful in ACL and ankle rehab, dual-task drills also fit general injury-prevention programs for in-season athletes, since practices and games always demand attention be shared between movement and decision-making. Any athlete who wants their mechanics to hold up under game speed can benefit.

How is dual-task training different from a standard return-to-sport test?

A standard return-to-sport test — like a single-leg hop for distance — measures movement quality with an athlete's full attention on the task, in a quiet, controlled setting. Dual-task training and testing add a mental challenge on top of that movement, checking whether the same quality holds up when attention is divided, which is closer to what actually happens on the field.
