The Effects of Equipment Modification on Children's Self-I and Basketball Shooting Performance

Abstract

The purpose of this study was to examine the effects of modification of basketball size and basket height on shooting performance and self-efficacy of girls and boys 9 to 12 years of age. Subjects (N = 74) completed a self-efficacy questionnaire before and after shooting 10 baskets under four conditions. Shooting conditions were a combination of basketball size (women's or men's) and basket height (10 or 8 ft). Repeated measures analyses of variance indicated that children made more baskets and had higher shooting scores at the 8-ft basket than the 10-ft basket. This was especially evident for girls and 9- and 10-year-old children. Self-efficacy was higher prior to shooting, and boys had higher self-efficacy than girls. Self-efficacy was highest when children shot at the 8-ft basket. These results indicated that basket height modification can positively influence children's shooting performance and self-efficacy.

Effect of two different forms of three-point line on game actions in girls’ mini-basketball

“…The frequency of shot attempts from outside the free throw lane and of lay-ups was not different between the two designs that were studied. This demonstrates that the three-point line with which participants played in the first championship better facilitated the playing and enjoyment of these youth participants in accordance with their capabilities (Piñar et al, 2002(Piñar et al, , 2003Piñar, 2005;Arias et al, 2009), which, according to the bibliography should foster an increase in the perceived competence (Hassandra et al, 2003), in the fun and enjoyment (MacPhail et al, 2008), and in self-efficacy (Bandura, 1977;Chase et al, 1994). The predominance of these motives should allow for greater adherence to mini-basketball, specifically, and to sport participation, in general (Hassandra et al, 2003;Weiss & Williams, 2004;Xiang et al, 2004).…”

“…Therefore, in the first championship, the possibilities to attempt and score a three-point shot were more suitable for the capacities of the players. This would contribute to the increase in the levels of perceived self-efficacy (Bandura, 1977;Chase et al, 1994), which likewise reflects on motivation (Bandura, 1977;Chase, 2001). Piñar (2005), when including a threepoint line in the 3-on-3 modality that was similar to the adult three-point line but at four meters from the hoop, found that the girls achieved a successful three-point basket in 4% of the ball possessions, for a total of nine baskets.…”

Reducing the pitch length: Effects on junior cricket

“…Shortening the pitch should lead to greater efficacy and self-efficacy on the part of bowlers, similar to that found when basket height was modified in basketball. 18 The difference between the numbers of double bounce deliveries in club and county bowling may be explained by the fact that under the club match rules everyone in the fielding side except the wicket keeper bowls, whilst in county games a minimum of five players from the eleven must bowl (and naturally the best bowlers are chosen). Furthermore county bowlers have effectively been selected because they can cope with the current pitch length for their age group, possibly because of better technique, but also perhaps because they are comparatively tall.…”
