Journal ArticleDOI
Changes in force, cross-sectional area and neural activation during strength training and detraining of the human quadriceps
TL;DR: Hypertrophy produced by strength training accounts for 40% of the increase in force while the remaining 60% seems to be attributable to an increased neural drive and possibly to changes in muscle architecture.
Journal ArticleDOI
Energy cost of walking and running at extreme uphill and downhill slopes
TL;DR: The estimated maximum running speeds on positive gradients corresponded to those adopted in uphill races; on negative gradients they were well above those attained in downhill competitions.
Journal ArticleDOI
Force of knee extensor and flexor muscles and cross-sectional area determined by nuclear magnetic resonance imaging
TL;DR: It is concluded that no significant difference exists between the maximum stress of knee extensor and flexor muscles despite large differences in their absolute values of force and CSA and that the NMR imaging technique enables accurate in-vivo determination of the CSA of individual muscles.
Journal ArticleDOI
Skyscraper running: physiological and biomechanical profile of a novel sport activity
TL;DR: Experiments revealed that best skyscraper runners maintain a constant vertical speed and HR throughout the race, while others suddenly decelerate, negatively affecting the race performance.
Journal ArticleDOI
Impact of telerehabilitation after sports injuries on psychological outcomes during the COVID-19 pandemic
TL;DR: The telerehabilitation program carried out during the emergency, was effective in promoting clinical improvements, maintaining almost all psychological outcomes stable and preventing the worsening of psychological distress.
