Outline of Final Research Achievements

The Hammerobics is a postural control exercise that approaches neuromuscular control, developed to prevent chronic fatigue resulting from repetitive exercise and to improve overall posture control, muscle balance, and coordination.　A study comparing muscle activity during the Hammerobics squat and traditional static squat was conducted on healthy individuals. The results showed a significant increase in muscle activity of the lower limb and trunk muscles during the Hammerobics squat.　Furthermore, in the Hammerobics exercises with extremely light loads, there was no difference in muscle activity compared to exercises with heavier loads, suggesting the effectiveness of light load Hammerobics. These findings have been widely disseminated through conference presentations and published papers.

Academic Significance and Societal Importance of the Research Achievements

ハンマロビクス運動において下肢体幹筋の筋活動が有意に高まり、且つ軽い重さのものでも重量のあるものと同等の活動量が認められた。このことからハンマロビクス運動が、アスリート、ノンアスリートに関わらず、バランス能力向上、また腰痛予防の新たなエクササイズとして効果が期待される。
