eccentric cycle ergometers. To overcome such difficulty, the components used to build an eccentric cycle ergometer have been briefly described. 3 – 5 However, these early ergometers were constructed using mostly custom parts that resulted in rather complex and costly designs. With the advancements in

In high-performance sprint kayak settings, laboratory tests are commonly used to track changes in fitness and performance. 1 Even though commercially available kayak ergometers have been designed to replicate the specific technical demands of kayaking, the metabolic demands of the different

The kayaking stroke is complex and involves upper limb and trunk movements in 3 dimensions combined with coordinated leg movements. Kinematic analyses of elite flat-water paddlers during paddling on a kayak ergometer 1 – 4 and during on-water paddling 4 , 5 have previously been conducted. Upper

Rowing ergometers can be found in most gyms and fitness centers, but many people who use them regularly have little or no instruction in rowing technique. It is not known whether nonrowers who regularly practice ergometer rowing are at risk of musculoskeletal problems. This study was done to quantify the differences in kinematics, kinetics, and musculoskeletal loading of competitive rowers and nonrowers during ergometer rowing. An experiment was performed to collect kinematic, external force, and EMG data during er-gometer rowing by 5 university-level competitive rowers and 5 nonrowers. Kinematic and external force data were input to a 3-D whole-body musculo-skeletal model which was used to calculate net joint forces and moments, muscle forces, and joint contact forces. The results showed that competitive rowers and nonrowers are capable of rowing an ergometer with generally similar patterns of kinematics and kinetics; however, there are some potentially important differences in how they use their legs and trunk. The competitive rowers generated higher model quadriceps (vastus) muscle forces and pushed harder against the foot cradle, extending their knees more and their trunks less than the nonrowers during the drive phase. They also had higher contact forces at the knee and higher peak lumbar and knee flexion moments. The ratio of average peak vastus force to average peak erector spinae force in the experienced rowers was 1.52, whereas it was only 1.18 in the nonexperienced rowers.

Maximal sprints in the leg cycle ergometer exercise are commonly used in routine athletic testing as well as in studies investigating the physiological adaptations to strenuous exercise. 1 These tests provide valid measures of anaerobic performance, which is a determinant of success in short
