In the trained group, the triceps brachii muscle exhibited greater concentric power during the DS than during the RDS.

Furthermore, a negative correlation was detected between the area under the Oxy-Hb curve and triceps brachii muscle thickness among the whole study population (Figure 7).

(2007) analyzed the effects of different ageing times and calcium chloride injection on the color, WHC and tenderness of lamb biceps femoris, longissimus and triceps brachii muscles. They found that ageing affects the reduction of WHC of the triceps brachii muscles but not of the biceps femoris and longissimus muscles, even though the SF values of the biceps femoris and longissimus muscles are affected by ageing.

Prime movers for the bench press exercise include pectoralis major, anterior deltoid, and triceps brachii muscles (Ojasto and Hakkinen, 2009).
