STRENGTH TRAINING FOR THE FOOT – 2014


METHODS
– 12 healthy males
– Flexion of all toe joints against a 3-kg load was implemented
– 200 repetitions once per day, 3x per week, for a period of 8 weeks

RESULTS
– Significant changes for:
1. intrinsic foot flexor strength scores
2. foot arch shape
3. vertical jumping
4. 1-leg long jumping
5. 50-m dash time.


THE POTENTIAL OF TOE FLEXOR MUSCLE TO ENHANCE PERFORMANCE – 2013


INTRODUCTION/PURPOSE
– The metatarsal phalangeal joint (MPJ) and its crossing toe flexor muscles (TFM) represent the link between the large energy generating leg extensor muscles and the ground
– We examined the functional adaptability of TFM to increased mechanical stimuli and the effects on walking, running and jumping performance

METHODS

– 15 men performed a heavy resistance TFM strength training with 90% of the maximal voluntary isometric contraction (MVIC)
– 7 weeks (560 contractions) for the left and right foot

– Athletic performance was determined by measuring jump height and distance
RESULTS
– Left and right MPJ plantar flexion moments in the dynamometer, external MPJ dorsiflexion moments and jump distance in horizontal jumping increased significantly


THE POTENTIAL FOR TOE FLEXOR TO PRODUCE FORCE – 2012


INTRODUCTION/PURPOSE
– Long and short toe flexor muscles (TFM) cross the ankle joints and metatarsal phalangeal joints (MPJ) and work against gravity during human locomotion
– Measured Maximal moments around the MPJ during maximal voluntary isometric contractions (MVIC) of the TFM as a function of ankle joint and MPJ position
– 20 men performed MVIC of the TFM in a custom-made dynamometer
CONCLUSIONS
– MPJ dorsal flexion is a necessary function in the push-off phase of human locomotion to work against the loss of the mechanical output at the forefoot caused by plantar flexion of the ankle
