Experiment Design and Methods
3.1.
Participants
Fourteen physically active students (7 female, 7 male) who were attending under- or postgraduate
programs at the Faculty of Sports Science participated voluntary in the study. Participants were
excluded if there was a history of musculoskeletal problems or functional mobility impairments.
All participants provided informed consent according to the procedure approved by the Review
Board of the University of Extremadura (Appendix A).
The mean age, stature and mass (and standard deviation) of the participants was of 22.6 (2.1)
years, 68 (9) kg, and 171 (10) cm, respectively. Table 3.1 shows descritive statistics of age and
anthropometric characteristics for both genders. Male subjects’ height ranged from 50 th to 99 th
percentile stature for Spanish male workforce, while female subjects’ height ranged from 5 th to
95 th percentile stature for Spanish female workforce. The male subjects were in the 5 th percentile
of body mass index (BMI) for Spanish male workforce, while female subjects were on the the
second quartile of BMI for Spanish female workforce, with BMI of about 23 kg/m2 for both genders
(Benjumea, 2001).

Instrumentation
The study was conducted in the Biomechanics of Human Movement and Ergonomics lab at the
University of Extremadura. The lab was equipped with a video-based optoelectronic stereophotogrammetric system (OSS) (MaxPRO, Innovision Systems, Inc.), a force measurement system
with two force platforms mounted on a ground-level concrete slab (Dinascan 600M, IBV, Valencia,
