Background Rating of perceived exertion (RPE) is considered a valid method for prescribing prolonged aerobic steady-state exercise (SSE) intensity due to its association with physiological indicators intensity, such as oxygen uptake (V̇O 2 ) or heart rate (HR). However, these associations between psychological and were found during graded tests (GXT) but are currently used prescribe SSE even though the transferability validity relationships GXT not investigated. The present study aims verify whether (a) RPE-HR RPE-V̇O relations GXTs SSEs, (b) duration affect relations. Methods Eight healthy physically active males (age 22.6 ± 1.2 years) enrolled.

Purpose The Talk Test (TT ) is recognised as a practical method for prescribing exercise intensity during incremental exercise, although its applicability to prolonged steady-state – particularly with respect physiological drift remains underexplored. Therefore, this study aimed evaluate whether workloads at different TT stages predict responses training. Methods Well-trained individuals (1–3 h of hiking, 3–4 times per week) performed (2-min stages) determine the equivocal (EQ), last positive (LP) and positive-1 (LP-1) stages. Participants then completed 60-min uphill walking bouts LP-1, LP EQ intensities in random order. Repeated measures ANOVA Tukey post-hoc tests assessed differences across exercise. Results During LP-1 bouts, stable conditions were observed percentage maximum heart rate (% HRmax) (< 85% HRmax), rating perceived exertion (RPE) 4/10), blood lactate (2–3 mmol · l–1) score (~1.2/3). In contrast, EQ, all values showed significant drift, including HR (> 95% RPE (~7/10), (~7 (~2.4/3). Conclusions Training based on or provides consistent moderate-intensity domain, minimal Steady-state stage results comparable heavy severe domain maximal steady-state).

Monitoring is a fundamental part of the training process to guarantee that programmed loads are executed by athletes and result in intended adaptations enhanced performance. A number monitoring tools have emerged during last century sport. These capture different facets (eg, psychophysiological, physical, biomechanical) acute bouts chronic while presenting specific advantages limitations. Therefore, there need identify what more efficient each sport context for better process.We present discuss fine-tuning approach monitoring, which consists identifying combining best with experts' knowledge settings, designed improve (1) control actual (2) understanding athletes' adaptations. Instead using single-tool approaches or merely subjective decision making, identification combination assist decisions (ie, triangulation) necessary understand link between their impact on health Future studies should elaborate setting.The requires simultaneous use several valid practical tools, instead single tool, effectiveness practices when added knowledge.

Optimizing endurance exercise intensity prescription is crucial to maximize the clinical benefits and minimize complications for individuals at risk or with cardiovascular disease (CVD). However, standardization remains incomplete due variations in guidelines. This review provides a practical updated guide health professionals on how prescribe rehabilitation (CR) populations, addressing international guidelines, applicability across diverse settings resource availabilities. In context of CR, cardiopulmonary test (CPET) considered gold standard assessment, based ventilatory thresholds (VTs) preferable methodology. where this approach isn't accessible, which frequently case low-resource environments, approximating VTs involves combining objective assessments—ideally, tests without gas exchange analyses, but least alternative functional like 6-minute walk test—with subjective methods adjusting prescriptions, such as Borg's ratings perceived exertion Talk Test. Therefore, enhancing offering personalized physical activity guidance patients CVD rely aligning workouts individual physiological changes. A tailored promotes consistent impactful routine outcomes, considering patient preferences motivations. Consequently, selection implementation best possible should consider available resources, an ongoing emphasis strategies improve delivery quality training FITT-VP model (frequency, intensity, time, type, volume, progression).

The perceived exertion construct creation is a landmark in exercise physiology and sport science. Obtaining relatively easy, but practitioners often neglect some critical methodological issues its assessment. Furthermore, the definition, neurophysiological basis, practical applications have evolved since construct’s inception. Therefore, we revisit careful work devoted by Gunnar Borg with psychophysical methods to develop construct, which resulted of two scales: rating (RPE) category-ratio 10 (CR10). We discuss contemporary definition that considers as conscious perception how hard, heavy, strenuous is, according sense effort command limbs feeling heavy breathing (respiratory effort). Thus, other exercise-evoked sensations would not hinder reported exertion. then describe mechanisms involved genesis during exercise, including influence peripheral feedback from skeletal muscles cardiorespiratory system (i.e., afferent feedback) efferent copies motor respiratory drive corollary discharges), well interaction between them. highlight essential details should consider when using RPE CR10 scales, such original scales utilization, descriptors anchoring process. Finally, present can use assess fitness, individualize intensity prescription, predict endurance performance, monitor athletes’ responses physical training.

Deficits myopathy may include weakness, atrophy, stiffness, myalgia, extra‐muscular manifestations.

Abstract Background Endurance exercise intensities can be categorized into moderate, heavy, and severe domains based on physiological responses during incremental testing. Since the evaluation of metabolic thresholds is not always possible, this study assessed accuracy fixed intensity anchors to estimate lactate thresholds. Methods 165 (64 females, 101 males) recreational runners performed a maximal treadmill test. The first (LT1) second (LT2) were determined as percentages maximum heart rate (HR), oxygen consumption (VO 2 ), running speed, alongside rating perceived exertion (RPE). Sex-specific mean values used determine threshold analyze error magnitude for each method. Results Females had higher relative HR, VO , speed at LT1 compared males ( p < 0.001). In pooled data, absolute estimating varied from 0.6 0.8 km/h 4.9–7.4 bpm while LT2 errors ranged 0.4 2.8–5.2 bpm, respectively. speed-derived estimations yielded smallest magnitudes, RPE-derived least accurate. Estimating increased respective 1.0 8.4 LT1, 1.1 6.7 LT2. Conclusion occurred in suggesting need sex-specific anchors. estimates most accurate, but estimation impaired prediction accuracy. Thus, optimal method also depends availability values.
