PURPOSE: The main purpose of the present study was to determine physiological responses in wheelchair basketball (WB) matches in relation to heart rate (HR), match load (ML), differentiated perceived exertion (dRPE), lactate concentrations (LA), and tympanic temperature (TEMP), while specifying the individual player's playing time during different types of matches. METHOD: Nine Spanish First Division WB players participated in the study. Three groups were determined for each observation (i...

This study examined complex terrain march performance and cardiorespiratory responses when carrying different Soldier loads. Nine active duty military personnel (age, 21 ± 3 yr; height, 1.72 ± 0.07 m; body mass (BM), 83.4 ± 12.9 kg) attended two test visits during which they completed consecutive laps around a 2.5-km mixed terrain course with either a fighting load (30% BM) or an approach load (45% BM). Respiratory rate and heart rate data were collected using physiological status monitors. Training impulse (TRIMP) scores were calculated using Banister's formula to provide an integrated measure of both time and cardiorespiratory demands...

PURPOSE: This study provides a retrospective analysis of a large competition database describing the intensity and load demands of professional road cycling races, highlighting the differences between men's and women's races. METHOD: Twenty male and ten female professional cyclists participated in this study. During 4 consecutive years, heart rate (HR), rating of perceived exertion (RPE) and power output (PO) data were collected during both male (n = 3024) and female (n = 667) professional races...

PURPOSE: To assess and compare the validity of internal and external Australian football (AF) training-load measures for predicting preseason variation of match-play exercise intensity (MEI sim/min) using a variable dose-response model. METHODS: Twenty-on professional male AF players completed an 18-wk preseason macrocycle. Preseason internal training load was quantified using session RPE (sRPE) and external load from satellite and accelerometer data. Using a training-impulse (TRIMPs) calculation, external load expressed in arbitrary units (a...

The aim of this study was to validate the quantification of internal training load (session rating perceived exertion, sRPE) and the effect of recall timing of sRPE during high-intensity functional training (HIFT) sessions. Thirteen male HIFT practitioners (age 27.2 ± 33 years, height 177.1 ± 4.0 cm, body mass 81.1 ± 9.0 kg) were monitored during two common HIFT training sessions: Fight Gone Bad (FGB) and Fran. The Edwards summated heart-rate-zone method was used as a reference measure of internal training load...

The cortisol awakening response (CAR) is commonly used as a marker of psychological stress, however it is unknown whether CAR is affected by regular physical exercise induced stress. PURPOSE: Therefore, the purpose of this study was to assess the relationship between training load and CAR. METHODS: Recreational endurance athletes were recruited from local club running groups. Subjects (n = 15) completed training logs for two weeks, with various training loads, including psychometric analysis (RESTQ-Sport)...

PURPOSE: Session rating of perceived exertion (sRPE) is an often-used measure to assess athletes' training load (TL). However, little is known about which factors could optimize the quality of data collection thereof. The aim of this study was to investigate the effects of the survey methods and the time points when sRPE was assessed on the correlation between subjective (sRPE) and objective (heart-rate training impulse; TRIMP) assessment of TL. METHODS: In the first part of the study, 45 well-trained subjects (30 men and 15 women) performed 20 running sessions with a heart-rate monitor and reported sRPE 30 min after training cessation...

PURPOSE: To assess the sensitivity of nocturnal heart-rate-variability-monitoring methods to the effects of late-night soccer training sessions in female athletes. METHODS: Eleven female soccer players competing in the first division of the Portuguese soccer league wore heart-rate monitors during sleep at night throughout a 1-wk competitive in-season microcycle, after late-night training sessions (n = 3) and rest days (n = 3). Heart rate variability was analyzed through "slow-wave sleep episode" (10-min duration) and "hour by hour" (all the RR intervals recorded throughout the hours of sleep)...

BACKGROUND: The associations between internal and external measures of training load and intensity are important in understanding the training process and the validity of specific internal measures. OBJECTIVES: We aimed to provide meta-analytic estimates of the relationships, as determined by a correlation coefficient, between internal and external measures of load and intensity during team-sport training and competition. A further aim was to examine the moderating effects of training mode on these relationships...

This study evaluated the changes in ratios of different intensity (rating of perceived exertion; RPE, heart rate; HR, power output; PO) and load measures (session-RPE; sRPE, individualized TRIMP; iTRIMP, Training Stress Score™; TSS) in professional cyclists. RPE, PO and HR data was collected from twelve professional cyclists (VO2max 75 ± 6 ml∙min∙kg-1 ) during a two-week baseline training period and during two cycling Grand Tours. Subjective:objective intensity (RPE:HR, RPE:PO) and load (sRPE:iTRIMP, sRPE:TSS) ratios and external:internal intensity (PO:HR) and load (TSS:iTRIMP) ratios were calculated for every session...

The aims of the study were to describe the physiological profile of a 65-km (4000-m cumulative elevation gain) running mountain ultra-marathon (MUM) and to identify predictors of MUM performance. Twenty-three amateur trail-runners performed anthropometric evaluations and an uphill graded exercise test (GXT) for VO2max, ventilatory thresholds (VTs), power outputs (PMax, PVTs) and heart rate response (HRmax, HR@VTs). Heart rate (HR) was monitored during the race and intensity was expressed as: Zone I (<VT1), Zone II (VT1-VT2), Zone III (>VT2) for exercise load calculation (training impulse, TRIMP)...

Enteral supplementation for nutritional support in pediatric oncology patients remains nonstandardized across institutions and between providers. Pediatric oncology patients frequently fail to meet their growth curve percentiles, lose weight, and/or are malnourished due to both the oncologic process as well as side effects from chemotherapy and radiation treatments. Methods of increasing weight include enteral feeding (nasogastric, nasoduodenal/jejunal, or gastrostomy), parenteral intravenous feeding, and oral supplementation...
