The lactate responses to incremental exercise, particularly the lactate threshold (LT), correlate strongly with various types of endurance performance. LT, however, possesses some disadvantages, such as
A scarce number of methods to identify LT
The need for a "subjective" identification of LT
The influence of external factors, such as CHO ingestion
All options (combination of A, B, and C) are correct
The relationship between power output and the time for which it can be sustained is better described by
A hyperbolic curve
A sigmoidal curve
A parabolic curve
An exponential curve
The amount of work that can be done during exercise above critical power is termed as
W′
D'
CP
All options (combination of A, B, and C) are correct
In an exercise intensity below the critical power, it could be expected
Absence of an accentuated slow component of pulmonary oxygen uptake (VO2)
Relatively stable blood lactate concentrations
Relatively stable muscle phosphocreatine levels
All options (combination of A, B, and C) are correct
In an exercise intensity above the critical power, it could be expected
Presence of an accentuated slow component of pulmonary oxygen uptake (VO2)
Relatively stable blood lactate concentrations
Relatively stable muscle phosphocreatine levels
All options (combination of A, B, and C) are correct
The power–time relationship is fundamental in exercise physiology because
It offers a framework for exploring and understanding skeletal muscle bioenergetics and the metabolic and cardio-respiratory responses to exercise
It provides a powerful tool for fitness diagnostics and monitoring the physical impact of different types of interventions
It provides performance prediction in continuous high-intensity endurance exercise
All options (combination of A, B, and C) are correct
The process of fatigue development during severe-intensity exercise may be linked to
The reduced recruitment of type II muscle fibers
The reduced muscle efficiency
The increased concentration of blood lactate
The stability of muscle substrates and metabolites
According to Joyner's model, three main factors play a role in endurance performance. These factors are
VO2max, "lactate threshold", and "efficiency"
VO2max, "efficiency", and maximal speed
"lactate threshold", "efficiency", and maximal speed
"lactate threshold, "maximal speed, and anaerobic reserve
According to Joyner's model, "efficiency" interacts with the performance to establish
The speed or power that can be generated at this oxygen consumption
The speed or power that can be generated without any increase in blood lactate concentrations
The oxygen consumption that can be sustained for a given period of time
The oxygen consumption that can be sustained for an infinite time
The exercise intensity can influence the development of fatigue. During exercise at a severe domain, for example, a common responses is
Loss of efficiency
Reduced accumulation of fatigue-related metabolites
Reduced glycogen depletion
All options (combination of A, B, and C) are correct
