The purpose of this investigation was to explore the effects of barefoot and minimally shod footwear on effective mass, and determine the implications that this has for transient loading during running. Fifteen male runners ran at 4.0 m/s in five different footwear conditions (barefoot, running trainer, Nike-free, Inov-8 and Vibram five-fingers). Kinematics were collected using an 8 camera motion capture system and ground reaction forces via an embedded force platform. Effective mass was examined using impulse-momentum modelling and differences between footwear were examined using one-way repeated measures ANOVA. The findings showed that effective mass was significantly larger in the barefoot (11.47 %BW), Nike-free (9.81 %BW), Inov-8 (12.10 %BW) and Vibram five-fingers (8.84 %BW) compared to the running trainer (6.86 %BW). Furthermore, instantaneous loading rate was significantly larger in the barefoot (347.55 BW/s), Nike-free (178.76 BW/s), Inov-8 (369.93 BW/s) and Vibram five-fingers (339.37 BW/s) compared to the running trainer (133.18 BW/s). It was also revealed that there were significant positive associations between effective mass and the instantaneous rate of loading for each footwear. The findings from the current investigation indicate that effective mass has key implications for the generation of transient forces and also that running barefoot and in minimally shod footwear may place runners at increased risk from impact related injuries compared to the traditional running shoes

PURPOSE:The aim of the current investigation was to utilize a musculoskeletal simulation 17 approach to resolve muscle forces during the pedal cycle, in order to specifically examine the 18 effects of chainring geometry on patellofemoral loading during cycling.
RESULTS:No significant (P>0.05) differences in patellofemoral force or stress were found 26 throughout the pedal cycle between chainring conditions. It was also shown that no 27 significant (P>0.05) differences in patellofemoral force per 20 km joint were evident (round 28
Effects of tennis shoes and running footwear on anterior cruciate ligament loading1 during a maximal change of direction manoeuvre. The aim of the current investigation was to examine the effects of tennis shoes and running 7 footwear on the loads experienced by the ACL during a maximal change of direction task.
8Thirteen male participants performed maximal change of direction movements in tennis 9 shoes and running footwear. Lower limb kinematics were collected using an 8 camera motion 10 capture system and ground reaction forces were quantified using an embedded force In addition, it was shown that the peak rotational moment was a significant predictor of peak
