About this study

After meeting the eligibility criteria for the study, university athletes have their general athletic condition variables evaluated in the laboratory and in the field. Subsequently, athletes with high and low arches perform 12-week foot muscle strengthening exercises to re-evaluate the variables in both athletes with high and low arch types who performed the strengthening exercises, as well as those with neutral arch who did not perform the exercises.

Primary outcomes

  1. Alterations change from baseline of the muscles of the center of gravity at 12 weeks

    Time frame: Baseline and week 12

    Measurement of the activity of the muscles of the center of gravity with electromyography

    • Voltage amplitude of the anterior rectus muscle measured in millivolts
    • Erector spinae muscle voltage amplitude measured in millivolts
    • Voltage amplitude of the external oblique muscle measured in millivolts
    • Voltage amplitude of the Internal oblique muscle measured in millivolts

    Electrodes were placed on the subjects according to literature recommendations (Oliva-Lozano & Muyor, 2020). Three sets of three exercise repetitions were performed (García-Vaquero et al., 2012).

  2. Alterations change from baseline of static stability: total mean distance, Anterioposterior distance and mediolateral distance at 12 weeks

    Time frame: Baseline and week 12

    The static stability in terms of total mean distance, Anterioposterior distance and mediolateral distance were measured in millimeters.

    The stability was measured when the athlete stood on the dominant leg trying to maintain balance for 10 seconds.

  3. Alterations change from baseline of static stability: total mean speed, anterio-posterior speed and mediolateral speed at 12 weeks

    Time frame: Baseline and week 12

    The static stability in terms of static stability: total mean speed, anterio-posterior speed and mediolateral speed were measured in millimeters/seconds The stability was measured when the athlete stood on the dominant leg trying to maintain balance for 10 seconds.

  4. Alterations change from baseline of static stability: covered area at 12 weeks

    Time frame: Baseline and week 12

    The static stability in terms of static covered area was measured in millimeters² The stability was measured when the athlete stood on the dominant leg trying to maintain balance for 10 seconds.

  5. Alterations change from baseline of dynamic stability: mean power at 12 weeks

    Time frame: Baseline and week 12

    The dynamic stability in terms of mean power was measured in watts/kilogram

    The participants were instructed to perform five single-leg jumps using their dominant foot.

  6. Alterations change from baseline of dynamic stability: left-right and forward/backward displacement at 12 weeks

    Time frame: Baseline and week 12

    The dynamic stability in terms of left-right and forward/backward displacement were measured in centimeters The participants were instructed to perform five single-leg jumps using their dominant foot.

  7. Alterations change from baseline of dynamic stability: covered area at 12 weeks

    Time frame: Baseline and week 12

    The dynamic stability in terms of covered area measured in centimeters² The participants were instructed to perform five single-leg jumps using their dominant foot.

  8. Alterations change from baseline in sport performance of maximum oxygen consumption (VO2max) and anaerobic threshold (AT) at 12 weeks

    Time frame: Baseline and week 12

    We used an Ergospirometry system to assess:

    VO2max and AT measured in milliliters/kilogram/minute

    They followed Marcos' protocol for a continuous treadmill exercise test (Marcos et al., 2018) and estimated VO2max and AT.

  9. Alterations change from baseline in sport performance of countermovement jump test: maximum force measured at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of countermovement jump test: maximum force measured in Newton/kilogram.

    For the countermovement jump (CMJ), participants started upright, knees and hips flexed, and then jumped while crossing their hands behind their back (Bobbert et al., 1996).

  10. Alterations change from baseline in sport performance of countermovement jump test: rate of force development at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of countermovement jump test: rate of force development measured in Newton/kilogram/second.

    For the countermovement jump (CMJ), participants started upright, knees and hips flexed, and then jumped while crossing their hands behind their back (Bobbert et al., 1996).

  11. Alterations change from baseline in sport performance of countermovement jump test: maximum power at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of countermovement jump test: maximum power measured in Watts/kilogram.

    For the countermovement jump (CMJ), participants started upright, knees and hips flexed, and then jumped while crossing their hands behind their back (Bobbert et al., 1996).

  12. Alterations change from baseline in sport performance of countermovement jump test:maximum velocity at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of countermovement jump test: maximum velocity measured in meters/second.

    For the countermovement jump (CMJ), participants started upright, knees and hips flexed, and then jumped while crossing their hands behind their back (Bobbert et al., 1996).

  13. Alterations change from baseline in sport performance of record time 40-meter sprint test at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of of 40-meter sprint test: record time measured in seconds. To measure the 40-meter sprint, photocell sensors and biomechanical equipment were used and participants ran at their maximum speed over a distance of 40 meters

  14. Alterations change from baseline in sport performance of speed 40-meter sprint test at 12 weeks

    Time frame: Baseline and week 12

    Sport performance of of 40-meter sprint test: speed measured in meters/second. To measure the 40-meter sprint, photocell sensors and biomechanical equipment were used and participants ran at their maximum speed over a distance of 40 meters
