Schaffert N, Mattes K, Effenberg AO. An investigation of online acoustic information for elite rowers in onwater training conditions. J. Hum. Sport Exerc. Vol. 6, No. 2, pp. 392-405, 2011. Presenting acoustic information has become increasingly interesting for technique training and control in various sports. In elite rowing, acoustic feedback is a new and promising application to optimize the ...

We measured physiological responses of elderly recreational skiers of different fitness and skiing abilities. Six subjects (mean age: 61.2 ± 4.6 yrs; Wt: 76.8 ± 15.6 kg; Ht: 1.69 ± 0.10 m; BMI: 26.9 ± 5.0) were tested in a laboratory and during 30 and 75 min of recreational downhill skiing. Oxygen uptake (VO2), heart rate (HR), blood lactate (LA) concentration, and diastolic (DBP) and systolic ...

It is generally accepted that crew rowing requires perfect synchronization between the movements of the rowers. However, a long-standing and somewhat counterintuitive idea is that out-of-phase crew rowing might have benefits over in-phase (i.e., synchronous) rowing. In synchronous rowing, 5 to 6% of the power produced by the rower(s) is lost to velocity fluctuations of the shell within each row...

Alpine skiing is one of the most popular leisure time winter sporting activities. Skiing imposes high requirements concerning physical fitness, particularly regarding balance abilities. The main objective of this study was to evaluate the changes in balance performance of recreational skiers after a seven-day ski camp. A total of 78 students - 24 women and 54 men - participated in the study. Th...

PURPOSE This study evaluated the validity of ergometer tests against the criterion of on-water rowing and determined the reliability of field measurements by comparing results between ergometer (ERG) and on-water (OW) tests. METHODS Seven male rowers completed incremental tests on a Concept2 rowing ergometer and in a single scull. Average power output, oxygen consumption (VO2), heart rate (HR...

Propulsion in water requires a propulsive force to overcome drag. Male subjects were measured for cycle frequency, energy cost and drag (D) as a function of velocity (V), up to maximal V, for fin and front crawl swimming, kayaking and rowing. The locomotion with the largest propulsive arms and longest hulls traveled the greatest distance per cycle (d/c) and reached higher maximal V. D while loc...

A 40 year old man sustained a flaccid paralysis of his right upper extremity in a water skiing accident on August 22nd, 1976. At the time of the injury the patient was being towed on water skis, when another boat cut across his tow rope. The force of the boat hitting his tow rope, combined with the wakes of both boats, caused the patient to be thrown forcefully into the air, with his right arm ...

Analysis of measured kinematic parameters is commonly used in competitive sports to optimize athletes’ performance. The progress in technology offers new ways for displaying feedback information to athletes. In rowing, synchronous visual feedback is regularly used, but the presentation of acoustic information is a new and promising application for technique training and monitoring. This paper d...
