The use of wearable sensor technology for athlete training monitoring is growing exponentially, but some important measures and related devices have received little attention so far. Respiratory frequency (fR), example, emerging as a valuable measurement monitoring. Despite the availability unobtrusive measuring fR with relatively good accuracy, not commonly monitored during training. Yet currently measured vital sign by multiparameter in military field, clinical settings occupational...
Perfectionism in sports has been shown to be associated with burnout athletes. Whether perfectionism predicts longitudinal changes athlete burnout, however, is still unclear. Using a two-wave cross-lagged panel design, the current study examined perfectionistic strivings, concerns, and 101 junior athletes (mean age 17.7 years) over 3 months of active training. When structural equation modeling was employed test series competing models, best-fitting model showed opposite patterns for...
To compare critical speed (CS) measured from a single-visit field test of the distance-time relationship with "traditional" treadmill time-to-exhaustion multivisit protocol.Ten male distance runners completed and tests to calculate CS maximum performed above (D'). The involved 3 runs on single visit an outdoor athletics track over 3600, 2400, 1200 m. Two field-test protocols were evaluated using either 30-min recovery or 60-min between runs. exhaustion at 100%, 105%, 110% velocity VO2max, 24...
Recent theory and research suggest that perfectionism is a personal factor contributing to athletes’ vulnerability doping (using banned substances/drugs enhance sporting performance). So far, however, no study has examined what aspects of in junior athletes. Employing cross-sectional design, this attitudes towards 129 male athletes (mean age 17.3 years) differentiating four perfectionism: perfectionistic strivings, concerns, parental pressure be perfect, coach perfect. In the bivariate...
Perfectionism in sports has been shown to predict longitudinal changes athlete burnout. What mediates these over time, however, is still unclear. Adopting a self-determination theory perspective and using three-wave design, the current study examined perfectionistic strivings, concerns, autonomous motivation, controlled burnout 141 junior athletes (mean age = 17.3 years) 6 months of active training. When multilevel structural equation modeling was employed test mediational model,...
Training load (TL) is a widely used concept in training prescription and monitoring also recognized as an important tool for avoiding athlete injury, illness, overtraining. With the widespread adoption of wearable devices, TL metrics are increasingly by researchers practitioners worldwide. Conceptually, was proposed means to quantify dose predict its resulting effect. However, has never been validated measure dose, there risk that fundamental problems related calculation preventing advances...

The purpose of this study was to assess the validity and reliability Wattbike cycle ergometer against SRM Powermeter using a dynamic calibration rig (CALRIG) trained untrained human participants. Using CALRIG power outputs 50–1 250 W were assessed at cadences 70 90 rev.min−1. Validity data also obtained from 3 repeated trials in both populations. 4 work rates used during each trial ranging 50–300 W. demonstrated significant differences (P<0.05) between across cadences. Significant existed...
To monitor training-related changes in gross efficiency (GE) over the course of a competitive cycling season.Fourteen trained cyclists (mean +/- SD: 34 + 8 yr, 74.3 7.4 kg, Wmax = 406 43 W, V O2max 59.5 3.8 mL x kg min) with at least 3 yr experience completed five laboratory tests during season. The measured lactate threshold (LT), onset blood accumulation (OBLA), maximal oxygen uptake (V O2max), minute power (Wmax), and GE. data were analyzed using repeated-measures ANOVA Pearson's...
Exercising at the maximal lactate steady state (MLSS) results in increased but stable metabolic responses. We tested hypothesis that even a slight increase above MLSS (10 W), by altering state, would reduce exercise performance capacity. Eleven trained men our study performed: one ramp-incremental tests; two to four 30-minute constant-load cycling trials determine PO (MLSSp ), and ten watts (MLSSp+10 which were immediately followed time-to-exhaustion test; test with no-prior exercise....
Perfectionistic athletes may train harder and for longer than non-perfectionistic athletes, leaving them susceptible to elevated levels of training distress. So far, however, no study has investigated the relationships between perfectionism distress, a key indicator overtraining syndrome. Furthermore, determined psychological predictors Using two-wave design, present examined perfectionistic strivings, concerns distress in 141 junior (mean age = 17.3 years, range 16–19 years) over 3 months...

Purpose This study was designed to examine the effects of moderate-intensity exercise on performance, gross efficiency, 30-s sprint power output. Methods Two separate experiments were conducted. After a controlled warm-up, subjects completed as much work possible 5-min test (EXP1) or maximal (EXP2). These initial bouts followed by...
Swain (1997) employed the mathematical model of Di Prampero et al. (1979) to predict that, for cycling time-trials, optimal pacing strategy is vary power in parallel with changes experienced gradient and wind speed. We used a more up-to-date validated coefficients (Martin al., 1998) quantify time savings that would result from such optimization strategy. A hypothetical cyclist (mass = 70 kg) bicycle 10 were studied under varying velocities (-10 m x s(-1)), gradients 10%), strategies. Mean...
The purpose of this study was to assess the influence age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one four groups: young old trained cyclists, untrained individuals. All participants completed an incremental ramp test measure their peak O2 uptake, maximal heart rate, minute power output; a submaximal gross efficiency (GE) at series absolute relative work rates; and, in only, 1-h time trial. Finally, all underwent biopsy right...
