Summary
Ankle dorsiflexion range of motion significantly changes after the first warm-up in speed skating. This finding helps optimize athlete preparation and tailor ankle mobility training for better performance.
Area of Science:
- Sports Medicine
- Biomechanics
Background:
- Optimal ankle dorsiflexion is crucial for the crouched position in speed skating.
- Understanding changes in ankle mobility during training is key for performance.
Purpose of the Study:
- To investigate the evolution of ankle dorsiflexion range of motion throughout a training day.
- To identify factors influencing ankle dorsiflexion in speed skaters.
Main Methods:
- Thirty short-track speed skaters' maximum ankle dorsiflexion was measured using a digital inclinometer.
- Measurements were taken multiple times per side, per day, over two training days.
- The study analyzed the impact of repetition, day, side, team level, sex, and time point.
Main Results:
- Ankle dorsiflexion did not significantly change with repeated measures or across training days.
- A significant difference was observed between the first measurement and subsequent measurements.
- Sex and team level did not significantly influence ankle dorsiflexion.
Conclusions:
- Ankle dorsiflexion range of motion significantly changes only after the initial warm-up.
- Findings can inform pre-competition preparation and ankle mobility training for speed skaters.

01:10Ankle Joint
1.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:28Muscles of the Leg that Move the Foot and Toes
1.4K
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....
