When compared to puma kicks, frame by frame video analysis
revealed that 23 test subjects took a longer period of time to move from heel
strike to heel lift while running in cleated shoes. (Figure 5). Freeze frame
analysis demonstrated a more dorsiflexed foot position during full foot contact
(an average of 7 degrees) during stance phase while running in cleated shoes in
26 air max shoes (figures 6a, 6b).
F-scan sensor data was able to capture a characteristic plantar pressure
"foot print" of very highly focused pressures in the rearfoot as well
as a rough transition from rearfoot to forefoot while running in cleated shoes
(figures 7a, 7b). A characteristic footprint was reproducible in 21 of the 36
test subjects. It should be noted that the "air jordan shoes" was most reproducible in test subjects who had pes planus foot types
with limited ankle dorsiflexion. The "foot print" was least
reproducible in test subjects with cavus foot types. The average plantar
pressure was noted to be in the 3O-psi(pounds per square inch) range in
non-cleated shoes, and in the 70 psi range wearing cleated shoes. See also figures
8a, 8b. Discussion Data gathered from both the video and F-scan analysis
between running shoes and soccer cleats confirms the negative heel nike shox r4. It is this negative heel
that plays a crucial role in the high percentages of young soccer players who
develop Sever's disease, by not only increasing the direct pressure placed on
the calcaneal epiphysis, but by also increasing the traction on the epiphysis
primarily via the Wholesale football
shirt shop In addition to the increased pull and pressure on the calcaneal
epiphysis, the repetitive nature of the sport, constant running in cleated
shoes, must also be considered as a factor. If one is able to decrease the
amount of negative heel (via. Heel lifts, orthotic management, soccer shoe
redesign, etc...), then one can decrease the tendency for young soccer players
to develop heel pain and or posterior heel cord tendinitis. Treatment options
for mild heel pain or calcaneal apophysitis should include 1/8" to ¼"
heel lifts in both shoes, elastic ankle bracing, ice massage before, during and
after play, and warm up stretching exercises. If the pain persists or increases
than turf or china wholesale soccer jersey
should be worn with heel lifts, bracing, and a reduction in both playing and
training time should be implemented. When the symptoms persist and the player
is noticeably limping from the pain, discontinuation of play is recommended
with immobilization of the foot and anide in a short leg walking cast, cast
boot, or soft replica soccer
jersey store cast.
