Abstract Succi, PJ, Dinyer-McNeely, TK, Voskuil, CC, Abel, MG, Clasey, JL, and Bergstrom,
HC. Responses to exercise at the critical heart rate vs. the power output associated with the …

Objectives: This study examined the time course of changes and patterns of responses in
electromyographic amplitude (EMG AMP) and EMG mean power frequency (MPF) for the …

Firefighting tasks may require near maximal levels of cardiorespiratory fitness. Previous
research has indicated that body fat percentage (BF%) and aerobic capacity (VO2peak) are …

Abstract Purpose This study examined:(1) the sustainability of the critical heart rate (CHR)
minus 5 b min− 1 (CHR− 5) and CHR plus 5 b min− 1 (CHR+ 5);(2) the ratings of perceived …

Purpose This study examined the power output adjustments and subsequent shifts in
metabolic (V̇O2) demands as well as minute ventilation (V˙ E), respiratory rate (RR), and …

Vol. 56, No. 5, pp. 917n926, 2024. Purpose: This study quantified the metabolic demands
(oxygen uptake (VO2)), power output adjustments, changes in the VO2/power output ratio …

of Critical Power, Critical Heart Rate, Time to Exhaustion, and Average Heart Rate during …

Recommendations for endurance exercise prescription are often based on percentages of
heart rate (HR) or the volume of oxygen consumption (V˙ O2) maximum or reserve that is …

PURPOSE This study compared the V̇O 2 corresponding to the critical heart rate
(CHRV̇O 2) and the physical working capacity at the heart rate fatigue threshold (PWC hrt …

Aerobic exercise with the correct intensity can attenuate motor and non-motor symptoms of
Parkinson's disease (PD) and improve the quality of life. However, a specific, validated, non …
