“…In relation to SF, this variable can reveal individual strategies to increase running speed ( Dorn et al, 2012 ) or achieve top-end running speeds ( Salo et al, 2011 ). Indeed, the consistency in SF was shown to decrease as speed differences increased (tested running speeds: 10–18 km/h) ( Patoz et al, 2022 ) and each runner was shown to self-optimize his step length over SF ratio ( Hunter et al, 2017 ; van Oeveren et al, 2021 ). Even in subgroups of individuals with similar sprint velocities, a range of SF and step length combinations are present ( Hunter et al, 2004 ).…”

Duty factor (DF) and step frequency (SF) were previously defined as the key running pattern determinants. Hence, this study aimed to investigate the association of DF and SF on 1) the vertical and fore-aft ground reaction force signals using statistical parametric mapping; 2) the force related variables (peaks, loading rates, impulses); and 3) the spring-mass characteristics of the lower limb, assessed by computing the force-length relationship and leg stiffness, for treadmill runs at several endurance running speeds. One hundred and fifteen runners ran at 9, 11, and 13 km/h. Force data (1000 Hz) and whole-body three-dimensional kinematics (200 Hz) were acquired by an instrumented treadmill and optoelectronic system, respectively. Both lower DF and SF led to larger vertical and fore-aft ground reaction force fluctuations, but to a lower extent for SF than for DF. Besides, the linearity of the force-length relationship during the leg compression decreased with increasing DF or with decreasing SF but did not change during the leg decompression. These findings showed that the lower the DF and the higher the SF, the more the runner relies on the optimization of the spring-mass model, whereas the higher the DF and the lower the SF, the more the runner promotes forward propulsion.

“…The use of proper training techniques in hurdles must pay attention to speed and strength techniques. One application of strength training has been used by (Patoz et al, 2023) namely the use of dynamic body weight training. For this exercise is widely used by top athletic trainers in the world but the constraints on this exercise have not been scientifically proven in increasing speed.…”

The use of exercise in sports must be right on target on the physical component needed. Similarly, hurdling not only utilizes speed, but requires strength to get maximum results. The purpose of the study was to analyze the effects arising from the use of Running ABC exercises combined with Bodyweight Training. The study design used a two-group post-test pre-test of 22 trained male subjects enrolled in the study. The first stage includes initial tests to see initial ability and as a basis for determining the treatment group which is divided into two groups with ordinally paired patterns A-B-B-A for group alignment. Group 1 was given Running ABC exercises, and Group 2 Running ABC exercises were combined with Bodyweight Training. Each group was trained for 16 meetings. The test instrument used is a 50yard sprint over obstacles by measuring the speed of the athlete's travel time. The data analysis technique used was a difference test with IBM SPSS 24 statistics. The results of the study were obtained from data analysis there was a significant difference between group 1 who only used Running ABC exercises with group 2 who used Running ABC exercises combined with Bodyweight Training exercises with a difference value of 0.043<0.05. This means that running abc (agility, balance, and coordination) and body weight training are significant in increasing the running speed of hurdling athletes, but combining body weight training and running abc (agility, balance and coordination) is more effective than training using only one type of physical component exercise. By combining running abc exercises and body weight training, trainers can improve their athletes' overall fitness and technique, effectively improving balance, coordination, and functional strength.

“…Given that runners were injured at the time of testing in most studies assessing the association between biomechanics and AT, these findings of potential kinematic and GRF variables related to AT may primarily reflect postinjury compensations and not potential risk factors associated with developing AT. In addition, there were noted differences in testing conditions across these studies, such as running speed, which is known to have an effect on both running mechanics (15,16) and Achilles tendon peak forces and loading rates (17) and may contribute to the inconsistent findings. Given the limited prospective research assessing biomechanical differences between runners who do and do not go on to develop an AT, the aims of this study were 1) to prospectively identify preinjury running biomechanics that differ between collegiate runners who did and did not go on to develop AT and 2) determine if preinjury between-limb asymmetry in running biomechanics is associated with sustaining an AT.…”

Introduction Achilles tendinopathies (AT) are common in runners, but prospective data assessing running mechanics associated with developing AT are limited. Asymmetry in running mechanics is also considered a risk factor for injury, though it is unknown if the problematic mechanics occur on the injured limb only or are present bilaterally. Purpose To prospectively identify differences in pre-injury running biomechanics in collegiate runners who did and did not develop AT and determine if between-limb asymmetries were associated with which limb developed AT. Methods Running gait data were obtained pre-season on healthy collegiate cross country runners, and AT incidence was prospectively recorded each year. Spatiotemporal, ground reaction forces, and joint kinematics and kinetics were analyzed. Linear mixed effects models assessed differences in biomechanics between those who did and did not develop AT during the subsequent year. Generalized linear mixed effects models determined if the asymmetry direction was associated with which limb developed an AT, with odds ratios (OR) and 95% confidence intervals [95% CI] reported. Results Data from 106 runners were analyzed and 15 developed AT. Pre-injury biomechanics of runners who developed AT showed less peak knee flexion (non-injured: 45.9 degrees [45.2, 46.6], injured: 43.2 degrees [41.5, 44.9], p < 0.001), ankle dorsiflexion (non-injured: 28.7 degrees [28.0, 30.2], injured: 26.0 degrees [23.8, 28.3], p = 0.01), and knee extensor moment (non-injured: -2.18 Nm/kg [-2.24, -2.12], injured: -2.00 Nm/kg [-2.17, -1.84], p = 0.02). The limb demonstrating less peak knee flexion had a greater odds of sustaining an AT (OR = 1.29 [1.00, 1.65], p = 0.05). Conclusions Knee and ankle kinematics, in addition to knee kinetics, were associated with developing an AT. Monitoring these mechanics may be useful for prospectively identifying runners at risk of developing AT.
