exercises are used to
strengthen muscles around the shoulder joint including pushups and
pushups plus. Modifications to standard pushups are commonly used
clinically which include knee pushups, elbow pushups and wall pushups.
Detailed activation patterns of muscles will help in planning the
rehabilitation process and the training program. Objective. To compare
the myoelectric amplitude of shoulder muscles during pushup variations.
Design and Methodology. Thirty healthy male subjects within age group
of 20-30 years and mean height of 173.65 cm were recruited from a
convenience sample of college students. Surface electromyogram was
recorded from triceps, pectoralis major, serratus anterior and upper
trapezius while performing push ups and push up plus exercises.
Results. Triceps and pectoralis major muscles showed highest activity
during push up variations.. Lowest UT/SA ratio was found in EPP both in
the eccentric and the concentric phases and highest in KPP. Conclusion.
SPP is the ideal exercise for strengthening TRI and PM while for
patients with an imbalance of UT to SA, EPP is an ideal exercise to
allow SA strengthening and reduction of imbalance. Thus muscle specific
conditioning protocols can be developed which will be of benefit to
patients and athletes.
