Talent identification and development programs seek to recognise promote athletes with long-term potential in a particular sport. Coaches involved these are often required make inclusion or exclusion decisions based on their perceptions of an athlete’s potential. However, biological maturity can influence physical capabilities adolescent may bias coaches’ This study explored the relationship between variations maturity. Talented male Australian footballers (n = 264) from nine different teams...

Twenty-three athletes (age = 12.2 ± 0.9 years; height 1.63 0.08 m; mass 51.8 8.5 kg) completed two testing sessions separated by 7-weeks and were randomly assigned either...

It is believed that increasing the X-factor (movement of shoulders relative to hips) during golf swing can increase ball velocity at impact. Increasing may also risk low back pain. The aim this study was provide recommendations for three-dimensional (3D) measurement and lower trunk movement swing. This three-part validation involved; (1) developing validating models related algorithms (2) comparing 3D data obtained static positions representative visual estimates (3) dynamic swings images...

A total 40 male (23.9 ± 3.5 years) participated in 3, five-a-side SSGs; defined as “small” (20 × 30 m; 600 m 2 ), “medium” (30 1,200 “large” (40 50 2,000 ). Notational analyses enabled...

This study aimed to compare the perceptions of boys and girls regarding their gender-specific talent development environments (TDEs) in state-level youth soccer. Seventy-one players (girls, n = 35; boys, 36) aged 11–18 years completed Talent Development Environment Questionnaire (TDEQ-5), Sports Motivation Scale (SMS-6), Coach-Athlete Relationship (CART-Q), Self-Efficacy Outcome Expectancies (SEOE) strength training questionnaire. Mann–Whitney U tests Hedges’s g effect sizes were used...

Purpose: To confirm the effect of maturational differences on anthropometric and physical testing explore maturation technical skill coaches’ perceptions in adolescent Australian footballers. Methods: Athletes were recruited from a semielite under 16 competition ( n = 94, age 15.7 ± 0.3 years) completed anthropometric, physical, tests. Coaches each team provided subjective ratings athletes’ skills. Maturation groups derived years peak height velocity estimates, with classifications either...

Cue reactivity (CR) research has reliably demonstrated robust cue-induced responding among smokers exposed to common proximal smoking cues (eg, cigarettes, lighter). More recent work demonstrates that distal stimuli, most notably the actual environments in which previously occurred, can also gain associative control over craving. In real world, always occur within an environment; thus, a more informative test of how affect might be present these two cue types simultaneously.Using...

This study investigated the return to baseline of movement velocity and maximal strength following a strength-orientated session power-orientated in free-weight back-squat performed with concentric velocity. Fourteen strength-trained males completed (five sets five repetitions @80% one-repetition maximum) (three six @50% maximum ) randomised order over two weeks (e.g. week 1, power 2). The was then loads 20%, 40%, 60%, 80%, 90% 100% at 24, 48, 72 96 h exercise sessions assess squat strength....

This study aimed to investigate the influence of chronological age and maturation status on sprint acceleration characteristics in junior Australian football (AF) players. Biological maturity 109 subjects was assessed were grouped according predicted years from peak height velocity (PHV) (pre-, mid-, post-PHV) (13 years, 14 15 years). A one-way multivariate analysis variance magnitude-based decisions used determine between-group differences. Instantaneous measured during two maximal 30m...

Skilled golfers are reported to be more flexible than lesser able golfers, which may assist in increased x-factor (shoulder-pelvis separation) at the top of backswing. However, it is unknown if flexibility produces faster clubhead speed. The aim this study was investigate correlations amongst trunk and x-factor, as well association between speed low handicap golfers. Fifteen male who displayed a modern swing, had their static anatomical end-range motion (flexibility) driver swing kinematics...
