Abstract [sv]

Many everyday tasks and also many sports require good grip and forearm strength. Everything from carrying boxes and lifting a child to grab the arms and legs in various martial arts, or holding a tennis racket involving the hand and forearm muscles in various ways. It is therefore important to train these muscles to prevent injuries and congestion and to perform well in sport. A well known way to train functional strength in the hand and forearm muscles is weight training with thick handles. The purpose of this study was to investigate the differences in muscle activity in the upper arm and forearm muscles as well as the deltoids between two bars of different diameter (28mm and 57mm) in two different weight training exercises using electromyography (EMG). The weight training exercises consisted of a pulling exercise in the form of a bench row and a pressing exercise in the form of close-grip bench press. The study also examines whether there is a connection between hand strength and muscle activity, and if there is any connection between hand size and muscle activity. Results show that muscle activity between the thick bars remained unchanged in the close-grip bench press. In the bench row exercise, however, significant increases were seen in the forearm flexors and m. biceps brachii while lifting the thicker bar. The forearm extensors showed an indication of muscle activity increases while lifting the thicker bar. However, there was no connection between hand strength and muscle activity and no correlation between hand size and muscle activity. The conclusion is that the pulling exercise with the thicker bar results in higher muscle activity in comparison to a standard Olympic bar in several muscles involved, not just those directly affected by the thicker bar.
