    Fitness and health

    Rowing is one of the few nonweight bearing sports that exercises all the major muscle groups, including quads, biceps, triceps, lats, glutes and abdominal muscles. Rowing improves cardiovascular endurance and muscular strength. Highperformance rowers tend to be tall and muscular: although extra weight does increase the drag on the boat, the larger athletes increased power tends to be more significant. The increased power is achieved through increased length of leverage on the oar through longer limbs of the athlete. In multiperson boats 2,4,or 8, the lightest person typically rows in the bow seat at the front of the boat.

    Rowing is a low impact activity with movement only in defined ranges, so twist and sprain injuries are rare. However, the repetitive rowing action can put strain on knee joints, the spine and the tendons of the forearm, and inflammation of these are the most common rowing injuries. If one rows with poor technique, especially rowing with a curved rather than straight back, other injuries may surface, including back pains. Blisters occur for almost all beginner rowers as every stroke puts pressure on the hands, though rowing frequently tends to harden hands and generate protective calluses. Holding the oars too tightly or making adjustments to technique may cause recurring or new blisters.
