Determinants of the gait transition speed during human locomotion: kinematic factors.
Hreljac A. Hreljac A. J Biomech. 1995 Jun;28(6):669-77. doi: 10.1016/0021-9290(94)00120-s. J Biomech. 1995. PMID: 7601866
Initially, a set of four criteria was established that must be satisfied by a variable in order to be considered a determinant of the PTS. Three of the criteria were able to be examined by searching previous literature in addition to being tested experimental …

When does a gait transition occur during human locomotion?
Hreljac A, Imamura RT, Escamilla RF, Edwards WB. Hreljac A, et al. J Sports Sci Med. 2007 Mar 1;6(1):36-43. eCollection 2007. J Sports Sci Med. 2007. PMID: 24149222 Free PMC article.
The purpose of this study was to determine whether the gait transitions during human locomotion occur abruptly, and if so, to determine the instant during a stride at which a transition occurs. ...The transition stride, however, did not resemble either a walk …

Patellofemoral compressive force and stress during the forward and side lunges with and without a stride.
Escamilla RF, Zheng N, MacLeod TD, Edwards WB, Hreljac A, Fleisig GS, Wilk KE, Moorman CT 3rd, Imamura R. Escamilla RF, et al. Among authors: hreljac a. Clin Biomech (Bristol, Avon). 2008 Oct;23(8):1026-37. doi: 10.1016/j.clinbiomech.2008.05.002. Epub 2008 Jul 15. Clin Biomech (Bristol, Avon). 2008. PMID: 18632195

On a subsequent day, subjects walked backward at speeds of 70, 80, 90, 100, and 110% of the BPTS and ran backward at speeds of 60, 75, 90, 100, and 120% of the BPTS while VO2 and RPE data were collected. ...There was a strong correlation (r = 0.82) between the BPTS …

Stride smoothness evaluation of runners and other athletes.
Hreljac A. Hreljac A. Gait Posture. 2000 Jun;11(3):199-206. doi: 10.1016/s0966-6362(00)00045-x. Gait Posture. 2000. PMID: 10802432
The purpose of this study was to compare an objective measurement of smoothness between a group of runners and a group of non-runners during running and fast walking. ...Subjects walked at a speed of 1.75 m.s(-1) and ran at a speed of 3.35 m.s(-1) on …

Individual effects on biomechanical variables during landing in tennis shoes with varying midsole density.
Hreljac A. Hreljac A. J Sports Sci. 1998 Aug;16(6):531-7. doi: 10.1080/026404198366498. J Sports Sci. 1998. PMID: 9756257
The results indicated that each subject responded uniquely to the shoes, and each demonstrated a preference for a particular pair of shoes. A need for single-subject designs exists when evaluating variations in athletic shoes....
