Biomechanical Analysis of Running Foot Strike in Shoes of Different Mass
I-Lin Wang et al
Journal of Sports Science and Medicine (2020) 19, 130 - 137

Different shoes and strike patterns produce different biomechanical characteristics that can affect injury risk. Running shoes are mainly designed as lightweight, minimal, or traditional cushioned types. Previous research on different shoes utilized shoes of not only different mass but also different shoe structures. However, it is unclear whether biomechanical changes during running in different shoe types with differing mass are the result of the structural design or the mass of the shoe. Thus, the purpose of this study was to investigate the effect of shoes of different mass on running gait biomechanics. Twenty male runners participated in this study. The experimental shoe masses used in this study were 175, 255, 335 and 415 g. The peak vertical ground reaction force increased with shoe mass (p < 0.05), but the strike index, ankle plantarflexion at initial contact, peak moment of the ankle during the stance phase, and initial contact angles of the lower extremity joints did not change. During the pre-activation phase, the integrated EMG data showed that the tibialis anterior muscle was the most activated with the 175 g and 415 g shoes (p < 0.05). During the push-off phase, the semitendinosus, lateral gastrocnemius and soleus muscles displayed higher activation with the heavier shoes (p < 0.05). The center of pressure also moves forward; resulting in mid foot striking. The lightest shoes might increase gastrocnemius muscle fatigue during the braking phase. The heaviest shoes could cause semitendinosus and triceps surae muscle fatigue during the push-off phase. Therefore, runners should consider their lower extremity joints, muscle adaptation and cushioning to remain in their preferred movement path.

Key Points
As shoe mass increases, the peak VGRF also increases.
The lightest shoes might increase tibialis anterior muscle activity during the pre-activation phase.
The heaviest shoes could increase semitendinosus, gastrocnemius lateralis and soleus muscle activity during the push-off phase.
The heaviest shoes could increase gastrocnemius lateralis and soleus muscle activity during the stance phase.

Somatosensory Perception of Running Shoe Mass may be influenced by
Extended Wearing Time or Inclusion of a Personal Reference Shoe, Depending
on Testing Method
JAMES G. SAXTON et al
International Journal of Exercise Science 13(6): 342-357, 2020.

Consumers may purchase running shoes
on the basis of their masses, yet little is known about shoe mass perceptual abilities. In this multi-part experiment,
four groups of twenty-five young adult males (total n = 100) were challenged to gauge the relative masses of five
unfamiliar running shoes. The four groups differed by the length of time they were given to wear the shoes (up to
1 minute versus 5 minutes) and whether or not they were able to use their own personal running shoes as a
reference. After wearing each individual pair of shoes, participants provided perceived comfort and heaviness
rankings using visual analogue scales (VAS). After wearing all five pairs of unfamiliar shoes, participants gave a
verbal ranking of relative shoe mass. Participants also hefted the shoes with their hands and positioned them in
order of relative mass. Extended wearing time improved overall verbal ranking accuracy, but did not improve mass
perception accuracy as determined by comparing VAS heaviness rankings to actual shoe masses. Conversely, use
of a personal reference shoe improved mass perception accuracy as determined by comparing VAS heaviness
rankings to actual shoe masses, but did not improve overall verbal ranking accuracy. Hand perceptual scores were
similar across the four groups, likely due to a ceiling effect. VAS comfort scores were unrelated to shoe masses. The
results suggest that wearing time and reference shoes may influence mass perception by the lower limb in a contextspecific manner.

Sensory Perception of Varied Shoe Masses in Running
Bahador Keshvari et al
J Am Podiatr Med Assoc. 2023 Jan-Feb;113(1):21-229

Background: Studies on the sensory perception of mass mostly focus on the hands rather than the feet. The aim of our study is to measure how accurately runners can perceive additional shoe mass in comparison to a control shoe (CS) while running, and moreover, whether there is a learning effect in the perception of mass. Indoor running shoes were categorized as a CS (283 g) and shoes with four additional masses: shoe 2 (+50 g), shoe 3 (+150 g), shoe 4 (+250 g), and shoe 5 (+315 g).

Methods: There were 22 participants in the experiment, which was divided into two sessions. In session 1, participants ran on a treadmill for 2 min with the CS and then put on one set of weighted shoes and ran for another 2 min at a preferred velocity. A binary question was used after the pair test. This process was repeated for all the shoes to compare them with the CS.

Results: Based on our statistical analysis (mixed effect logistic regression), the independent variable (ie, mass) did have a significant effect on perceived mass (F4,193 = 10.66, P < .0001), whereas repeating the task did not show a significant learning effect (F1,193 = 1.06, P = .30).

Conclusions: An increase of 150 g is the just-noticeable difference among other weighted shoes and the Weber fraction is equal to 0.53 (150:283 g). Learning effect did not improve by repeating the task in two sessions in the same day. This study facilitates our understanding about sense of force and enhances multibody simulation in running.

Joint kinematic and kinetic responses to added mass on the lower extremities during running
Itay Coifman et al
Appl Ergon. 2023 Aug 24

Aim: We analyzed the biomechanical response (joint angles, moments, and powers) to running with added leg mass. These data may help guide the design of wearable locomotor assistive devices (i.e., exoskeletons), which are becoming more prevalent.

Methods: 15 participants (7 females, 8 males) completed treadmill running trials (3m•s-1) normally and with lead mass (300-1350 g) attached to the thigh, shank, or foot, bilaterally. We quantified the lower limb biomechanics combining motion capture and ground reaction force data using standard inverse dynamics analysis.

Results: Only moderate kinematic changes occurred in response to the distal added limb mass. Maximum hip flexion and maximum knee flexion angles during swing phase increased by approximately 9% and 6% respectively for each 1 kg added to each foot. However, adding even small masses made dramatic changes to the joint moments and powers, mostly during the swing phase. For example, adding 1 kg to each foot increased maximum joint moments by as much as 40% (knee extension in late swing) and maximum joint power by as much as 50% (hip generation in late swing).

Conclusion: Leg joint kinematics were largely conserved in response to adding mass to the legs. Adding mass to the leg distally increased joint power mainly at the knee and hip joints during the swing phase, whereas adding mass proximally mainly affected the ankle joint mechanics during the stance phase. These changes have implications for shoe designs, people who run with added mass on their legs for sport/strength training and for the design of wearable devices.
