Determining the optimal balance between training load and recovery contributes to peak performance in well‐trained athletes. The measurement of heart rate (HRR) monitor this has become popular. However, it is not known whether impairment performance, which associated with training‐induced fatigue, accompanied by a change HRR. Therefore, aim study was retrospectively analyze relationship changes HRR cycling group cyclists ( n =14) who participated 4‐week high‐intensity (HIT) program. Subjects...
Objective: The purpose of this study was to examine ratings perceived exertion (RPE) and performance during repetitive maximal effort 40 km time trials as well after an intervention that aimed decrease certainty about the remaining distance exercise bout. In addition, we examined RPE bouts markedly different duration. Methods: Part 1: 12 well-trained, competitive-level cyclists completed five trials. During final trial all feedback withheld until kilometre. cause confusion distance, they...
Objective: The purpose of this study was to measure the effects an amphetamine (methylphenidate) on exercise performance at a fixed rating perceived exertion 16. Methods: Eight elite cyclists ingested 10 mg methylphenidate in randomised, placebo-controlled crossover trial. Results: Compared with placebo, subjects receiving cycled for approximately 32% longer before power output fell 70% starting value. At equivalent time which placebo trial terminated, had significantly higher outputs,...
Objective The purpose of this study was to determine the reliability and predictive value performance parameters, measured by a new novel submaximal cycle protocol, on peak power endurance cycling in well-trained cyclists. Methods Seventeen competitive male road racing cyclists completed four output (PPO) tests 40-km time trials (40-km TT). Before each test, all performed test (Lamberts Lambert Submaximal Cycle Test (LSCT)). Parameters associated with such as power, speed, cadence rating...
Purpose : Road cycling is a sport with extreme physiological demands. Therefore, there need to find new strategies improve performance. Heart-rate variability (HRV) has been suggested as an effective alternative for prescribing training load against predefined programs. The purpose of this study was examine the effect prescription based on HRV in road Methods Seventeen well-trained cyclists participated study. After initial evaluation week, performed 4 baseline weeks standardized establish...
This study aimed to investigate if performance measures are related success in professional cycling and highlight the influence of prior work done on these success.Power output data from 26 cyclists, a total 85 seasons, collected between 2012 2019, were analyzed. The cyclists classified as "climber" or "sprinter" into category 1 (CAT.1; ≥400 PCSpoints (successful)) CAT.2 (<400 (less successful)), based number procyclingstats-points (PCSpoints) for that particular season. Maximal mean power...
Object Selective dorsal rhizotomy (SDR) has been widely performed for the reduction of spasticity in patients with cerebral palsy during past 2 decades. The objective this study was to determine whether surgery yielded long-term functional benefits these patients. Methods authors present results from a prospective 20-year follow-up locomotor function 13 who underwent an SDR 1985. For comparison, we also gait data 48 age-matched healthy controls (12 at each 4 time points). Patients were...
The HIMS test, which consists of controlled exercise at increasing workloads, has been developed to monitor changes in training status and accumulative fatigue athletes. As the workload can influence day-to-day variation heart rate, intensity, is associated with highest sensitivity, needs be established goal refining interpretability these rate measurements. aim study was determine within-subject submaximal recovery subjects who reached different intensities. Thirty-eight participated this...
To present normative data for the record power profile of male professional cyclists attending to team categories and riding typologies.Power output registered from 4 teams during 8 years (N = 144 cyclists, 129,262 files, 1062 total seasons [7 (5) per cyclist] corresponding both training competition sessions) were analyzed. Cyclists categorized as ProTeam (n 46) or WorldTour 98) all-rounders 65), time trialists 11), climbers 50), sprinters general classification contenders 7). The was...
Purpose : To investigate how cycling time-trial (TT) performance changes over a season, both in “fresh” state and “fatigued” (durability). Additionally, the aim was to explore whether these are related underlying physiological factors such as gross efficiency, energy expenditure (EE), substrate oxidation (fat [FatOx] carbohydrate [CarbOx]). Methods Sixteen male semiprofessional cyclists visited laboratory on 3 occasions during season (PRE, START, IN) underwent test fresh fatigued states...
A change in heart rate at a controlled submaximal exercise intensity is used as marker of training status. However, the standard error measurement has not been studied systematically, and therefore rate, which can be considered relevant, determined. Forty-four subjects (26.5 +/- 5.4 years; mean deviation) participated running test same time day for 5 consecutive days. Heart rates were determined during each 4 intensities (2 minutes each) increasing 1-minute recovery period after stage. The...
In high-performance cycling, it is important to maintain a healthy balance between training load and recovery. Recently new submaximal cycle test, known as the Lamberts Lambert Submaximal Cycle Test (LSCT), has been shown be able accurately predict cycling performance in 15 well-trained cyclists. The aim of this study was determine predictive value LSCT 102 trained elite cyclists (82 men 20 women). All performed an test followed by peak-power-output (PPO) which included respiratory-gas...

To provide insights into a dose-response relationship between training and time-trial performance, as assessed in both "fresh" "fatigued" state (durability), including proposed underlying factors for durability: gross efficiency substrate oxidation (FatOx CarbOx). Ten male semiprofessional cyclists underwent performance test (after 38.6 [4.6] kJ·kg-1) before after an 8-week period, containing the measurement of efficiency, FatOx, CarbOx at submaximal intensity maximal time trials 1 (PO1) 10...
Abstract Purpose Selective dorsal rhizotomy (SDR) is a neurosurgical treatment used worldwide to reduce spasticity. The procedure has undergone many changes since its introduction in the early 1900s, and currently, different centers vary aspects of procedure. We surveyed on continents regarding SDR indications, surgical techniques, postoperative rehabilitation. Methods Ten with experience participated an online survey preparing for pre-conference workshop 2022. main topics were patient...
The aim of our study is to investigate whether coupling power output (PO) and heart rate (HR) data semi-professional road cyclists collected in the field helpful for optimising training process. Therefore, HR PO during all cycling activities were from 23 2 years. Weekly cyclist-specific response times (recovery, delay maximal time) extracted models connecting PO. Linear regression was performed between performance, defined as mean a 1- 10-min indoor time trial (TT) under controlled...
