OBJECTIVES Individual differences in adolescent exercise behavior are strongly influenced by genetic factors. The affective response to exercise is a potential source of these genetic influences. To test its role in the motivation to exercise, we estimated the heritability of the affective responses during and after exercise and the overlap with the genetic factors influencing regular voluntary...

High volume low intensity training sessions such as one hour rowing ergometer sessions are frequently used to improve the fitness of elite rowers. Early work has suggested that technique may decline over this time period. This study sought to test the hypothesis that "elite rowers can maintain technique over a one hour rowing ergometer session". An electromagnetic device, in conjunction with a ...

BACKGROUND Patients in Intensive Care Units (ICU) are often exposed to prolonged immobilization which, in turn, plays an important role in neuromuscular complications. Exercise with a cycle ergometer is a treatment option that can be used to improve the rehabilitation of patients on mechanical ventilation (MV) in order to minimize the harmful effects of immobility. METHODS/DESIGN A single-bli...

The purpose of this study was to develop a 3-minute, all-out test protocol using the Monark cycle ergometer for estimating the critical power (CP) and anaerobic work capacity (AWC) with the resistance based on body weight. Twelve moderately trained adults (mean age ± SD = 23.2 ± 3.5 years) performed an incremental cycle ergometer test to exhaustion. The CP and AWC were estimated from the origin...

Rowing injuries have been attributed to poor technique, suggesting a need to understand the mechanics of rowing and the influence on technique of different training regimes and ergometers. The aims of this study were to investigate the repeatability of the kinematics of the lumbopelvic region during rowing and to compare these kinematics between rowing on two different ergometers. An electromag...

The goal of this study was to assess the effects of amount of ergometer cycle training on Vo2max and body composition in overweight women. Forty-one sedentary premenopausal women, age 25 to 45 years, were randomly assigned in three groups. Cycle ergometer training consisted of one day per week for group A, two days per week for group B and three days per week for group C. Participants trained f...

Pre-participation screening is very important for prescribing and practising exercise safely. The aim of this study was to investigate both ratings of perceived exertion (RPE) and blood pressure responses in two different types of exercises with matching duration and indirectly determined working heart rate (HR). Participants were 23 male students, who were generally healthy but sedentary. The ...

An “all-out” tethered running on the treadmill represents an alternative form of exercise used for the assessment of anaerobic capacity. Contrary to the well known and frequently used “all-out” test on the cycle ergometer (Wingate anaerobic test), there is a lack of information concerning the parameters of anaerobic capacity obtained from tethered running on the treadmill. The aim of our study ...

The aim of the present study was to investigate effects of muscle fatigue on oxygen costs of ergometer cycling and slow component of pulmonary oxygen uptake (VO2) kinetics. Seven young men performed 100 drop jumps (drop height of 40 cm) with 20 s of rest after each jump. After the subsequent hour of rest, they cycled at 70, 105, 140 and 175 W, which corresponded to 29.6 ± 5.4, 39.4 ± 7.0, 50.8 ...
