Abstract

Pull-up and modified pull-up tests are frequently used for shoulder muscles
endurance evaluation by physical educators. Despite of using these tests, the
difference of muscle activation pattern in pull-up and modified pull-up tests has
not been documented clearly. However, the role of some important muscles
such as anterior deltoid, posterior deltoid, trapezius and latissimus dorsi have
not yet examined during these tests. This study aimed to determine effects of
pull-up and modified pull-up tests on the EMGs recordings from selected
muscles including anterior deltoid, posterior deltoid, biceps, triceps, pectoralis
major, trapezius and latissimus dorsi. Ten able-bodied males (age: 25.32 ±
3.95 yrs; weight: 72.31 ± 7.24 kg) who were able to do at least 5 pull-ups were
selected to participate in the study. Surface electromyographic data were
recorded from selected muscles using De Luca and Basmajian’s method.
ANOVA with repeated measures was employed for comparison of
electromyographic activity in the selected muscles during pull-up and modified
pull-up tests (p  0.05). The results revealed that in modified pull-up test
anterior deltoid, posterior deltoid and trapezius muscles activation were
significantly higher in comparison with pull-up test, while the EMG activity of
biceps, triceps and pectoralis major was significantly higher in pull-up test.

Abstract

Ankle sprain is one of the most commonly damaged lower extremities. More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (Coper people) and do not suffer from chronic ankle instability. The aim of this study was to compare EMG activity of the selected involved muscles in balance control strategies in athletes with chronic ankle instability, coper and healthy athletes during one leg standing. 11 noninjured controls and 13 participants with CAI and 10 ankle sprain ‘copers’ participated in this study. Each participant for 20 seconds maintained their single-foot balance on the 3rd and 12th balance points of Biodex, and EMG activity of the muscles was recorded by the electromyography device during this period.The significance level for all analyses was set as p≤0/05. The results showed Tibialis Anterior, Gastrocnemius and rectus abdominal in the participants with CAI had significantly lower levels of activity than coper group and rectus femoris and Gastrocnemius muscle activity in the participants with CAI had significantly lower levels of activity than control group (p≤0/05). Increasing muscle activity in the Coper group can be due to compensatory mechanisms, which results in greater stability of the trunk and ankle set.
