Dance training superior to physical exercise in inducing brain plasticity (2018)
Dance-based training may boost certain markers of brain plasticity in older adults more than repetitive gym-style exercise, according to a small study that compared choreography-focused classes with conventional fitness programs of similar intensity. Commenters highlight that dance layers coordination, rhythm, balance, and social interaction on top of cardiovascular effort, and relate personal experiences of improved proprioception, mood, and social life. Others are skeptical of the study’s statistical robustness and narrow scope (elderly participants, repetitive control exercises), arguing that any cognitively demanding, skill-based movement—such as martial arts, trail running, or complex weightlifting—might offer similar benefits.
Study scope and limitations
- Several commenters note the full title stresses “repetitive” exercise and “in the elderly”, criticizing the HN headline as overgeneralized.
- Participants were 63–80 years old, with dance involving constantly learning new, harder choreographies; the control group did repetitive exercises with low coordination demands.
- Some argue the result is “obvious”: adding mentally demanding learning on top of matched physical intensity should boost plasticity more than simple cardio or machines.
- Others question whether results generalize to younger adults or to more complex, skill-based sports.
Methodological skepticism
- Commenters with MRI/statistics background doubt the robustness of small structural brain changes over 6 months with this sample size.
- Concerns include tiny brain clusters, weak p‑values (e.g., BDNF around 0.046), possible multiple-comparisons issues, and limited behavioral differences (both groups improved similarly in attention and spatial memory).
- Some suspect non‑replicability and “neuroplasticity” being used too vaguely.
What might matter: complexity and learning
- Many suggest the key factor is continuous learning and complex coordination, not “dance” per se.
- Proposed equivalents: martial arts (esp. with kata/forms or BJJ problem‑solving), boxing/Olympic lifting, trail running on uneven terrain, balance training, skating/rollerblading, timing-based VR games, DDR/Beat Saber.
- The pattern: tasks that combine cardiovascular effort with balance, timing, spatial awareness, and ongoing skill acquisition.
Social and emotional components
- Dance is seen as inherently social and often partner‑based, adding touch, synchrony, and community, which are independently associated (in other research, per commenters) with mental health benefits.
- Several anecdotes describe dramatic improvements in mood, sociability, and life satisfaction in older dancers.
- Some argue social dynamics and close contact are major contributors; others note they can also be a source of anxiety or rejection.
Anecdotes and subjective effects
- Multiple participants report better proprioception, balance, musical analysis, and general “mental ease” after dance, martial arts, or balance-heavy sports.
- Others share long-lived, cognitively sharp relatives who danced or gardened extensively, highlighting that many engaging, embodied hobbies might help.
Practical takeaways in the thread
- Many emphasize that “the best exercise is the one you’ll stick with.”
- A common synthesis: choose activities that are physically demanding, cognitively complex, and ideally social—dance is one strong example among several.
