Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

Area of Science:

  • Sports Science
  • Biomechanics
  • Running Performance

Background:

  • Optimizing running economy is crucial for marathon performance.
  • Training modifications can alter biomechanical parameters.
  • Understanding the impact of step frequency on running is essential.

Purpose of the Study:

  • To investigate the effects of step frequency manipulation on biomechanical parameters during incline running.
  • To determine if altered step frequency impacts running economy at iso-efficiency speed.
  • To provide insights for coaches on improving athlete performance.

Main Methods:

  • 24 male marathon runners were divided into two groups: step frequency manipulation (SFM) and free step frequency (SFF).
  • Training involved a 2% incline for three weeks.
  • Lower limb kinematic parameters were measured pre- and post-training.

Main Results:

  • The SFM group showed a significant increase in step length (4.30%) and flight time (29.48%).
  • The SFM group also demonstrated a significant decrease in contact time (14%).
  • The SFF group did not exhibit similar biomechanical improvements.

Conclusions:

  • Step frequency manipulation during incline training can enhance key biomechanical variables associated with improved running performance.
  • This training strategy may be a valuable tool for coaches seeking to increase step length and improve athlete speed.
  • The findings suggest a potential method for achieving faster race times in marathon runners.
