Effect of different training models on motoric and swimming performance in prepubescent swimmers

Background and Study Aim. The aim of this study was to examine the effects of different training programs on the improvement of motoric and swimming performance prepubescent swimmers. Material and Methods. Forty-five children between the ages of 9 -11 years with at least 2 years of training experiences, participated in the study. Three different [(1) dry-land with elastic resistance band group + swimming (ERB); (2) dry-land without elastic resistance band (DL) + swimming and (3) swimming group (SG) with swimming training alone] training group were formed. And a 12-week training program was implemented thought the study. Biceps, chest, waist, hip, thigh body circumference measurements were taken from all participants. Vertical jump (VJ), flexed-arm strength (FAS), speed, upper body strength (UBS), Standing horizontal jump (SHJ), flexibility, aerobic endurance (AE), balance, and 50 m freestyle swimming (FS) score were tested on the participants. As statistical analysis, normality and homogeneity of variance assumption were checked (Shapiro-Wilk and Levene tests, respectively). A non-normal distribution was found. The values of each variable were expressed as mean ± standard deviation, and median. The training effects within the groups were evaluated using analyses of Friedman for repeated measures and the level of significance was set at p<0.05 for all tests. Results. There was a significant difference in SHJ, UBS, FAS, speed, and FS score among the assessment times 1-3 and 1-4 in both of ERB and DL training groups (p<0.05). ERB and DL training were significantly effective compared to the SG on VJ, FAS, speed, UBS, and freestyle swimming performance (p<0.05). Conclusions: The study findings showed that DL training more effected relatively on motoric performance.

The effect of varying encoding conditions on jazz, instrumental, and choral musicians’ memorization accuracy: Implications for music literacy

The primary purposes of this study were (1) to determine the effect of three encoding conditions (singing, playing, studying silently) on participants’ music memorization accuracy; (2) to examine potential differences between choral, jazz, and concert band musicians’ accuracy in completing the music memorization task; and (3) to determine whether ensemble affiliation yielded any performance advantages among the three presentation conditions. Three folk melodies were selected for memorization under the three encoding conditions. Participants ( N = 81) had 75 s to commit each melody to memory while studying silently, singing, or playing on a keyboard. Participants then notated the three melodies using conventional staff notation. A two-way analysis of variance (ANOVA) with repeated measures on one factor revealed significant differences based on participants’ ensemble affiliation. A Tukey’s honest significant difference (HSD) post hoc test revealed the jazz group had higher accuracy scores than the band group. No significant differences were found based on encoding conditions, and no significant interactions were found between the encoding conditions and ensemble groups. The experiment is framed by questions related to memory, reading, and differing notions of literacy.

A rectangular slot Yagi DGS microstrip filter with sharp rolloff and wide suppression band

A compact microwave lowpass filter based on defected ground structure (DGS), consisting of Yagi slot DGS resonators etched on the metallic ground plane of a microstrip line, is studied in this paper. The proposed lowpass filter was analyzed by parameter sweeping and optimal parameters were selected to design a prototype demonstrator filter. Measurements show the developed lowpass filter exhibits a 3dB cuto frequency of 3.07 GHz with a sharp transition between the passband and the stopband, low insertion loss of less than 0.6 dB in the passband and an in-band group delay of 0.4 ns. Moreover, an ultra-wide suppression band from 3.68 to over 20 GHz with a suppression level generally better than 20 dB is also observed from measurements.

Modified two-tension-band for patellar fractures

Objective To compare a modified two-tension-band (MTTB) technique with the AO tension band in treating patellar fractures. Methods This retrospective study included patients treated with AO tension band (group 1) or MTTB (group 2). Data obtained during serial follow-up evaluations of time to bony union, range of motion (ROM), Hospital for Special Surgery (HSS) score and complication rates, were analysed. Results Fractures healed in all 51 patients included in the study (group 1, n = 28; group 2, n = 23), with no statistically significant between-group difference in time to bony union. Regarding function results, group 2 had better HSS scores at 3 and 6 months postoperatively; however, at 1 year postoperatively, both groups had similar HSS scores and achieved acceptable flexion and ROM. The overall complication rate was significantly lower in group 2, but average costs were higher in group 2 versus group 1. Conclusion MTTB provides secure fixation and improved knee function at 3 and 6 months postoperatively, and has a lower complication rate with early mobilization, compared with the AO tension-band technique.

Cancer Related Fatigue and Upper Limb Disabilities Cannot Improve after 6 Weeks Resistance Training with Thera-Band in Breast Cancer Survivors

Aim. Breast cancer and its treatments lead to cancer related fatigue and upper limb disabilities. On the other hand, resistance training has positive benefits for breast cancer survivors. Thus, the aim of present study was to clarify the effect of resistance training with Thera – Band on CRF and upper limb disabilities in breast cancer survivors. Methods. Fifty women with breast cancer aged 29-65 were divided in to 2 groups: 1) resistance training with Thera- Band group (n=25) and 2) control group (n=25). Resistance training with Thera- Band group, after 5 minutes warm up, were performed the 9 resistance training with Thera – Band, from 8 to 12 repetitions and 2 sets in the first two weeks, 8 to 12 repetitions and 3 sets in the second two weeks and 8 to 12 repetitions and 4 sets in the third two weeks. The rest between each set was started from 90 seconds in the first week and was decreased to 45 seconds in the sixth week. Control group didn’t have any supervised or regular physical activity. Cancer related fatigue (CRF) and upper limb disabilities were surveyed by Piper Fatigue Scale and DASH questionnaire, respectively. Data were analyzed using by 2-way ANOVA (p≤0.05). Statistical Results. The findings of this study demonstrated that 6 weeks resistance training by Thera – Band has no significant effect on CRF and upper limb disabilities (p≥0.05). Conclusion. It can be concluded that exercise training with Thera- Band for 6 weeks cannot improve CRF and upper limb disabilities in breast cancer survivors. Future studies with large sample size and long period of intervention is suggested.

Hochtemperatur-Gehäuselager in der Doppelbandpresse

In den Doppelbandpressen der Berndorf Band Group geht es heiß her: Bei Temperaturen um die 400 °C können beispielsweise faserverstärkte Platten aus Thermoplasten hergestellt werden. Im Rollenmodul der Anlage kommen daher Hybridgehäuselager in einer Keramik/Edelstahl-Kombination zum Einsatz. Die selbstschmierenden Gehäuselagereinheiten trotzen nicht nur der extremen Hitze, sondern können auch große Druck-Belastungen aushalten und sind außerdem wartungsfrei.

A Pilot Study: Perceptual Effects of the Voodoo Floss Band on Glenohumeral Flexibility

Even though adaption of the Voodoo Floss Band is gaining momentum, evidence-based literature on its effectiveness remains sparse. The purpose of this quantitative observational design study was to investigate the effects of the Voodoo Floss Band on soft-tissue flexibility and perception of movement. A repeated-measures ANOVA with between-subjects factor demonstrated both groups significantly improved GH flexion range of motion from pretest to post-test but there was not a statistically significant difference between the groups. Perceptions of flexibility increased more for the Voodoo Floss Band group, demonstrating a psychological increase in GH flexion, but not a physical increase.
