“…To evaluate low back and hamstring flexibility, we measured the SAR in a box with a measuring scale marked in cm with 15 cm at the level of the feet [13]. This test was performed without shoes twice and the best trial in the nearest 0.5 cm was recorded.…”

Purpose The main aim of this study was to examine differences in physical and physiological characteristics, with an emphasis on anaerobic power, of male basketball players by age and playing position. Methods Basketball players (n = 101), classified into three age groups: under 15 years (U-15, n = 35, 14.28 ± 0.72 years), under 18 years (U-18, n = 35, 16.23 ± 0.74 years) and older than 18 years (Elite, n = 31, 25.66 ± 5.09 years), participated in this study. The variables under examination were anthropometric characteristics, body composition, physical working capacity test, 3-min step test, Wingate anaerobic test, force–velocity test, sit-and-reach test, handgrip strength test and countermovement vertical jump with arm swing. Results U-15, U-18 and elite players differed for all aforementioned parameters with the older group scoring better than the younger (η 2 ≥ 0.06, p < 0.048). In Elite group, centers were heavier and taller than guards (22.3 kg and 20.9 cm, respectively) and forwards (14.3 kg and 10.6 cm), and forwards were taller than guards (10.2 cm). Guards’ scores were higher than centers in maximal power (3.61 W kg−1) and in peak power (1.39 W kg−1). Forwards scored higher than centers in mean power (1.25 W kg−1). In the U-18 group, guards were stronger in the relative strength than centers (2.4 kg kg−1). In the U-15 group, centers were taller than guards (17.8 cm) and forwards (9.7 cm), and forwards were also taller than guards (8.1 cm). Conclusions Based on the findings of this study, it is concluded that positional differences, especially in anaerobic power, in male basketball vary by age. Thus, young basketball players should not be regarded as miniature adult basketball players with regard to their physical and physiological characteristics, and their positional specializatio

Purpose. The aim of this study was to examine the relationship between player position and physical fitness, with an emphasis on anaerobic power, in female soccer players. Methods. For this purpose, 54 first league female soccer players were recruited. They included goalkeepers (n = 4, age 22.89 ± 4.37 years), defenders (n = 21, 21.92 ± 3.81 years), midfielders (n = 22, 21.71 ± 4.70 years) and attackers (n = 7, 20.43 ± 4.70 years). Participants' anthropometric characteristics were measured and a physical fitness test battery was administered. Results. significant differences were observed in body fat percentage (F 3,50 = 3.06, p = 0.036, ŋ 2 = 0.16) with goalkeepers being fatter than defenders (mean difference 6.1%; 95% CI 0.3,11.9). Positional differences were also found in the sit-and-reach test (F 3,50 = 4.46, p = 0.007, ŋ 2 = 0.21), in which goalkeepers scored lower than defenders (-11.4 cm; 95% CI -21.4, -1.5) and midfielders (-10.0 cm; 95% CI -19.9, 0). Comparison of fat mass and endomorphy were statistically significant (p = 0.057 and p = 0.062, respectively), with goalkeepers showing the highest values; these differences were in the same direction as with body fat percentage. No positional differences were found in the other physical fitness components (aerobic capacity, anaerobic power, and muscle strength). Conclusions. Differences among player positions were observed in body composition (highest body fat percentage in goalkeepers) and flexibility (lowest score in goalkeepers). These trends are in agreement with previously published data concerning elite soccer players. These findings might be used as reference data by coaches and trainers to identify talent, select players, and monitor training.

“…The test has a high intrarater reliability [intraclass correlation coefficient (ICC) = 0.92-0.98] and test-retest reliability (ICC = 0.92-0.95) for the SRT. 1,2,6,10 The SRT was performed before normal training, and the player was not allowed to do any warm-up or stretching exercises before the test. The player was tested while sitting on the floor, with the legs together, the knees extended, and the soles of the bare feet placed against the foot panel of the test box (Figure 1 see Video, Supplemental Digital Content 1, http://links.lww.com/JSM/A104).…”
