TLDR
The dynamics of lactate accumulation in working muscle was studied in three subjects performing maximal bicycle exercise of 2, 6, and 16 min duration.Abstract:
The dynamics of lactate accumulation in working muscle was studied in three subjects performing maximal bicycle exercise of 2, 6, and 16 min duration. In separate experiments, the two longer maxima...read more

Failure of dobutamine to increase exercise capacity despite hemodynamic improvement in severe chronic heart failure
TL;DR: Administration of dobutamine in patients with severe chronic heart failure increased the cardiac index during maximal exercise but failed to increase exercise capacity, since arteriovenous oxygen difference is reduced and do butamine probably increases blood flow to the nonexercising tissues and not to the actively metabolizing muscles.

Lactate and contractile force in frog muscle during development of fatigue and recovery.
Robert H. Fitts,John O. Holloszy +1 more
TL;DR: Recovery of contractile force lagged behind the decrease in lactate; a given concentration of muscle lactate was associated with a higher contractiles force early during development of fatigue than late during recovery.

Factors determining symptoms in heart failure: comparison of fast and slow exercise tests.
TL;DR: The sensation of breathlessness in congestive heart failure is not simply related to raised pulmonary capillary wedge pressure, but may in part be due to stimulation of peripheral chemoreceptors in response to metabolic acidosis.

The maximally accumulated oxygen deficit as an indicator of anaerobic capacity
TL;DR: MAOD was higher for the sprinters and middle distance runners than for the long distance runners and control subjects, indicating a greater anaerobic capacity for the former two groups, and significant correlations were found between MAOD and both Wingate power and treadmill work for all subjects and betweenWingate power, Wingate capacity, treadmill work, and 300 m time for the athletes, suggesting that relationships do exist among MAOD
