... Considering that the shooting technique is one of the most important skill in basketball and that its's accuracy is decisive for winning or losing the competition, it is interesting to see which motor skills affects shooting accuracy. Vertical Jump performance has been regarded as measure of athleticism in sport (Montalvo et al., 2021). Also, it can be said that one of the basic movement skills applied during shooting in basketball is vertical jump (Hoffman, Stavsky, & Folk, 1995). ...

... Studies have found that moderate physical activity in the elderly can help stimulate their bodies [18][19][20], enhance muscle strength to produce real benefits, and improve overall muscle fitness. Proper muscle strength exercises can prevent injuries and slow down the degeneration of the body as well as avoid the symptoms of muscle loss. ...
... Historically, the vertical jump has been used as an indicator of neuromuscular performance by many coaches of different disciplines in the world (Montalvo et al., 2021). During the decade of the sixties, Professor Rodolfo Margaria was the first person to talk about the relevance of the so-called Stretch-Shortening Cycle (SSC) stating that a concentric contraction preceded by an eccentric one could generate higher levels of strength than an isolated concentric contraction (García-López et al., 2003). ...
... Despite the suggested application of the modified FMS for the older adult population, very few studies have investigated the feasibility of this tool for this population (Dietze-Hermosa, 2019;Fawcett, 2014;Ulrike et al., 2016). For example, recently, although Dietze-Hermosa et al. (2019, 2020 reported normative values for the modified FMS in active older adults, the relation between modified FMS scores and physical fitness in older adults remains unclear. Specifically, it is unknown whether better scores on the modified FMS are associated with enhanced physical fitness as measured by commonly used physical fitness tests. ...
