“…The Upper Quarter Y Balance test (YBT-UQ) is a widely used test procedure carried out in the field to obtain valid and reliable measurements of shoulder mobility/stability in healthy youth [1,2]. Carrying out the YBT-UQ test requires the subject to assume a push-up position on the floor (Fig 1A -1D) supported by one arm and reach as far as possible to the (a) medial (MD), (b) inferolateral (IL), and (c) superolateral (SL) direction with the other arm [3].…”

Background The Upper Quarter Y Balance test (YBT-UQ) is a field test for measuring shoulder mobility/stability. However, there is a lack of information regarding age- and sex-specific reference values for classifying the YBT-UQ performance of children and adolescents. Objective The aim was to investigate YBT-UQ performance in youth and to provide age- and sex-specific normative values. Method Six hundred and sixty-five persons (325 girls, 340 boys) aged between 10 and 17 years carried out the YBT-UQ test. Following this, maximum reach values, normalised in terms of arm length, were calculated for each arm (i.e., left and right) and reach direction (i.e., medial [MD], inferolateral [IL], superolateral [SL]), and the composite score (CS) per arm. Additionally, percentiles were displayed graphically and in tabular form, distinguished according to age and gender. Results In boys, those aged 14–15 years showed a higher achievement (e.g., MD direction) compared with both younger (12–13-year-olds) and older (16–17-year-olds) persons. In girls, differences related to age could only be observed for the IL direction and the CS, where the youngest age group (10–11-year-olds) achieved better results than the older groups. Sex-specific differences to the girls’ advantage could be observed in 12–13-year-olds (i.e., SL and CS), and to the boys’ advantage in 14–15-year-olds (i.e., for all reach directions) and 16–17-year-olds (i.e., IL and SL direction and CS). Further, curvilinear developments were observed with regard to the 10th, 50th, and 90th percentiles, and were more strongly marked in boys than in girls. Conclusions The obtained age- and sex-specific normative values for the YBT-UQ can be used by teachers, coaches, and therapists to classify the level of shoulder mobility/stability among 10–17 year-old children and adolescents.

“…Participant’s LL was determined from the anterior superior iliac spine to the most distal aspect of the medial malleolus [ 6 ]. The YBT-LQ test is a valid (concurrent, discriminative, and predictive) and reliable (moderate to excellent) tool to assess balance performance in youth [ 7 – 9 ].…”

Objective Previous studies reported significant improvements in static and dynamic balance performance following balance training during adolescence. However, it is unclear how equal training volume but different training frequencies per week affect training-induced adaptations. Thus, the present study investigated the effects of balance training frequency (i.e., 2 × 30 min per week or 3 × 20 min per week) on measures of static and dynamic balance in healthy male adolescents. Results Irrespective of balance training frequency, significant pretest to posttest improvements were detected for static (i.e., One-Legged Stance test, standing time duration) and dynamic (i.e., Lower Quarter Y Balance test, reach distance) balance performance. However, no group × test interactions were found. These results imply that balance training is effective to improve static and dynamic balance performance in healthy male adolescents, but the effectiveness seems unaffected by the applied balance training frequency.

Background The aim of this study was to compare the positional transversal release (PTR) technique to stretching and evaluate the acute effects on range of movement (ROM), performance and balance. Methods Thirty-two healthy individuals (25.3 ± 5.6 years; 68.8 ± 12.5 kg; 172.0 ± 8.8 cm) were tested on four occasions 1 week apart. ROM through a passive straight leg raise, jumping performance through a standing long jump (SLJ) and balance through the Y-balance test were measured. Each measure was assessed before (T0), immediately after (T1) and after 15 min (T2) of the provided intervention. On the first occasion, no intervention was administered (CG). The intervention order was randomized across participants and comprised static stretching (SS), proprioceptive neuromuscular facilitation (PNF) and the PTR technique. A repeated measure analysis of variance was used for comparisons. Results No differences across the T0 of the four testing sessions were observed. No differences between T0, T1 and T2 were present for the CG session. A significant time × group interaction for ROM in both legs from T0 to T1 (mean increase of 5.4° and 4.9° for right and left leg, respectively) was observed for SS, PNF and the PTR. No differences for all groups were present between T1 and T2. No differences in the SLJ and in measures of balance were observed across interventions. Conclusions The PTR is equally effective as SS and PNF in acutely increasing ROM of the lower limbs. However, the PTR results less time-consuming than SS and PNF. Performance and balance were unaffected by all the proposed interventions.
