An Examination and Critique of Current Methods to Determine Exercise Intensity

摘要: Prescribing the frequency, duration, or volume of training is simple as these factors can be altered by manipulating number exercise sessions per week, duration each session, total work performed in a given time frame (e.g., week). However, prescribing intensity complex and controversy exists regarding reliability validity methods used to determine prescribe intensity. This arises from absence an agreed framework for assessing construct different In this review, we have evaluated based on their ability provoke homeostatic disturbances changes oxygen uptake kinetics blood lactate) consistent with moderate, heavy, severe domains exercise. Methods include percentage anchor measurements, such maximal ( $${\dot{\text{V}}\text{O}}_{{{\text{2max}}}}$$ ), peak ( $${\dot{\text{V}}\text{O}}_{{{\text{2peak}}}}$$ ), maximum heart rate (HRmax), (i.e., power velocity— $${\dot{\text{W}}}_{{\max}}$$ $${\dot{\text{V}}}_{{\max}}$$ , respectively), derived graded test (GXT). despite common use, it apparent that fixed anchors has little merit eliciting distinct domain-specific perturbations. Some advocated using submaximal anchors, including ventilatory threshold (VT), gas exchange (GET), respiratory compensation point (RCP), first second lactate (LT1 LT2), steady state (MLSS), critical (CP), speed (CS). There some evidence support LT1, GET, VT delineate moderate heavy there most commonly methods, exception CP CS, As acute responses are not always predictive chronic adaptations, studies required verify whether will affect adaptations training. Better ways should help sport scientists, researchers, clinicians, coaches design more effective programs achieve greater improvements health athletic performance.
