If you can’t walk more, walk faster!
The British Journal of Sports Medicine has published a study examining associations between walking pace and cause-specific mortality.
The research used a series of population-based surveys from the UK between 1994 and 2008 which were linked to mortality records. Associations were then derived between walking pace and all-cause cancer and cardiovascular disease mortality.
50,225 walkers were analysed in total and findings revealed that walking at an average or brisk pace was linked to significant reductions in all-cause cancer and cardiovascular disease when compared to walking at a slow pace.
The authors concluded that “Walking pace could be emphasised in public health messages, especially in situations when increase in walking volume or frequency is less feasible”.
Effects of shoes on feet: New research
Research featured in The Journal of Foot and Ankle Surgery has examined the effects of wearing shoes between partially shod Maasai women’s feet and regularly shod Maasai and Korean women’s feet.
The study observed bilateral weightbearing radiographic foot and ankle examinations of 20 rural bush living Masssai women, and 20 regularly shod, urban living Maasia and Korean women. Angles measured included the hallux valgus angle, the first to second intermetatarsal angle, talonavicular coverage angle, talo-first metatarsal angle, Meary angle, naviculo-cuboidal overlap, and the medial cuneiform height.
Results showed that the talonavicular coverage angle, talo-first metatarsal angle, and naviculo-cuboidal overlap were significantly greater in the partially shod Maasai group. However, the hallux valgus angle, the first and second intermetatarsal angle, Meary angle, and the medial cuneiform height were greater in the regularly shod Maasai and Korean group. The authors concluded that “regularly wearing shoes would protect the feet from pes plano-valgus deformity, despite potentially contributing to hallux valgus deformity”
Static and dynamic navicular drop variations
A new study published in The Foot, has investigated the effects of gait and speed on dynamic navicular drop.
The cross-sectional study evaluated navicular drop in static and dynamic conditions on a treadmill while walking and running at three different speeds. Findings suggested that higher walking speed led to a significant decrease in navicular height at foot strike and a subsequent decrease of dynamic navicular drop. There was also a large effect of gait style with an increase in dynamic navicular drop when moving from walking to running at the same speed. The authors concluded that static and dynamic navicular drop measures differ substantially.
