Resilience

Originally, resilience referred to something’s general ability to for something to bounce back after being stuck. Now it primarliy represents the ability to endure and stay strong, similar to being courageous or robust (Mukherjee & Kumar, 2017).
In the field of sport psychology, resilience is mainly used to describe psychological strength (Smith et al., 1990), teamwork (Morgan et al., 2013), or organizational effectiveness. At these different levels, resilience is seen as the ability of an individual, a group, or an organization to adapt to challenging situations.
