简要总结
The proposed study will investigate the effect of alternating footwear model and workout-type on the occurrence of running-related pain. To achieve this goal participants will be randomly assigned into one of four different groups who will perform: 1) the same workout throughout a week in the same running shoe model, 2) alternating workout-types throughout the week in the same shoe model, 3) the same workout throughout a week in alternating shoe models, and 4) alternating workouts in alternating shoes. Participants will be characterized based on body alignment, strength, injury and training history. Pain and injury status will be monitored.

Only neutral and pronated foot postures (Foot Posture Index between -2 and 8) will be recruited
排除标准
- •have a history of surgery to their plantar fascia or Achilles tendon,
- •have a diagnosis of osteoarthritis - or other degenerative musculoskeletal disorder - affecting the lower extremity,
- •take analgesic or anti-inflammatory medication 2 or more times per week over the past 4 weeks,
- •take part in high impact activities 2 or more times per week during the study period
研究组 & 干预措施
Constant training/Constant footwear
Group 1 - Runners will be assigned identical training sessions over a 7-day period and will perform these runs in two pairs of the same assigned neutral-cushioned running shoe (Nike Pegasus). The weekly training volume will increase on a weekly basis in order to progressively increase training load in preparation for the half-marathon event.
干预措施: Constant training (Other)

Alternate training/Constant footwear
Group 2 - Runners will perform a variation of workouts, consisting of interval/speed work, tempo runs, and long-slow distance runs throughout each 7-day period. As with Group 1, weekly training volume will increase on a weekly basis. Runners in Group 2 will perform these runs in two pairs of the same assigned neutral-cushioned running shoe (Nike Pegasus).

Constant training/Alternating footwear
Group 3 - Runners will be assigned identical training sessions over a 7-day period but will alternate use of two different models of running shoes across successive workouts (Nike Pegasus and Nike Zoom Streak). The Zoom Streak has 10mm less midsole material, a less supportive heel counter and more flexible forefoot providing a more responsive feel to the runner.
