Inclusion criteria
Inclusion criteria: We included subjects that declared to be right or left handed dominant. Participants must reported no recent injury or participation in strength training program of the upper limb (three times/ week) in the last six months. All participants were required to refrain for upper body strength training outside the study and to maintain their normal daily routines.
Exclusion criteria
Exclusion criteria: Trained subjects, and women without oral pills contraceptive use or pregnancy knowledge
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Changes in strength and muscle activation Maximal voluntary isometric contraction (MVIC) MVIC of the elbow flexors will assess on both arms at 90º of elbow flexion and 30º of shoulder flexion on an adapted Scott bench (Fig. 1A). Subjects will perform a warm-up set for both arms at 50% 70% and 80% of the self-perceived maximum with 45 s rest between contractions. After warm-up, the subjects will perform three attempts of 3-s duration of their maximal isometric strength with 60 seconds of rest between attempts. The Scott bench will be adapted with a force cell to ensure elbow and wrist joint position (Revere transducers 200lb, Netherland). A strong verbal encouragement will give for each repetition for all participants, which will instruct to “pull as hard and fast as possible”. The load cell signal will amplified and record using a Trigno EMG system (Delsys EMGworks®, National Instruments, Boston, Massachussets, USA) connected to a personal computer (HP-15-ax001Ia, Hewlett-Packard, Inc., California, USA). The greater isometric force value out of three measurements will use for statistical analysis. | — |

| Functional performance of Upper limb The balance of the upper limb will assess with the modified Upper Quarter Y Balance Test (mUQYBT). The mUQYBT will perform following the guidelines of the YBT (Plisky et al., 2009). All participants will provide a demonstration of the procedures and allowed three practice trials, according the UQYBT procedures, in each direction on their right and left upper limb prior to data collection. Before to the test, the upper limb length will measure with the subjects in standing position and the shoulder abducted to 90° with the elbow full extended and the wrist and hand in neutral position. The measurements will take from the spinous process of C7 to the tip of the longest digit. The participants perform the testing procedures barefoot to eliminate any stability and balance issues from footwear. Three trials in each direction (upper-lateral, medial, and lower-lateral) will record for both arms. The best value from each of the three directions will add together and divided by three times the upper limb length and then multiplied by 100 to get the total composite score from each participant on both arms according to described recommendations (Gorman, Butler, Plisky, & Kiesel, 2012). | — |
