- Hippocrates, known as the "father" of modern medicine, made significant contributions to medical knowledge
- Galen, a prominent physician in AD 131-201, emphasized the "laws of health" including proper diet, exercise, and emotional control
- Renaissance figures like Leonardo da Vinci, Michelangelo Buonarroti, Vesalius, and William Harvey made key anatomical and physiological discoveries
- Claude Bernard, a renowned psychologist, discovered the liver's internal secretion of glucose
- A.V. Hill and other Scandinavian researchers pioneered studies on gas exchange in the lungs and blood flow redistribution during exercise
- Martti Karvonen is known for the "Karvonen formula" to predict optimal exercise training heart rate
- Exercise physiology concepts include homeostasis, stress, and the distinction between exercise and training
- The body's response to exercise intensity, as well as the impact of exercise on mortality rate and daily sitting, were discussed
- The concept of stress-adaptation and the potential negative effects of overtraining on the body were highlighted
- The energy continuum, specifically the breakdown of ATP and its significance in bodily function, was explained
