Heel strike is often to blame for Achilles’ tendon issues, plantar fascia pain, and patella tendon issues. Research shows that the force loading rate of the shin (tibia bone) is a bigger factor in injury risk than foot strike. The loading rate is how quickly how much force is applied.
Plantar fasciitis is an inflammatory condition of the plantar fascia which is a thick, fibrous ligament that runs along the bottom of the foot and connects the heel to the front of the foot. Someone with plantar fasciitis will experience intense pain at the bottom of their heel; in some cases, pain can radiate up the leg causing discomfort in the ankle and calf.
The iliopsoas is actually two muscles: the psoas and the iliacus. The psoas originates from the vertebrae T-12 vertebrae (the vertebrae where the lowest rib attaches) down to L-4. The iliacus muscle comes from the inside of the hip bone. Once the two merge, they attach to the top of the femur (thigh bone), on the inner surface.
Clients at Custom Performance use the run/walk strategy under the supervision and instruction of the physical therapists to progress return-to-run loading after injury, cover long distances in marathon training, and increase general endurance. Recently, I re-discovered a largely underutilized run/walk application: intervals for speed.
When it comes to building a training schedule, most runners and coaches follow a 7-day training plan which usually consists of some combination of speed work, tempo, long run, and easy days. For most, this seems to make sense given that our everyday lives and routines are structured around a Monday to Friday work week followed by a two-day weekend.
