Background: Conditioning activities such as resistance training can cause excitation of central nervous system resulting in Post-activation Potentiation phenomenon. Plyometric exercise also has an important role to develop Post-activation Potentiation following a resistance stimulus. So the purpose the study was to investigate the immediate effects of weighted plyometric exercise on sprint, agility and jump performance. Materials and methods: Twenty male university football players (age=21.3±1.5 years, body mass=63.3±9.5 kg, height=169.8±6.4 m) participated in this Single group pre-test post-test study. Agility Time (AT), Sprint Time (ST) and Counter-Movement Jump (CMJ) height were measured prior to and 1st and 5th minutes following plyometric exercise. Results: A repeated measures ANOVA employed at baseline (T0), 1 minute (T1), and 5 minutes (T5) post intervention showed significant effect for all the three outcome measures (p<0.001). Post-hoc Bonferroni pairwise comparison showed a significant decrease in both AT and ST from baseline to assessments at both T1 (p<0.001) and T5 (p<0.001), whereas there was a significant increase in the CMJ height. However, no statistical difference was found between T1 and T5 (p=0.058) in ST, but AT was significantly lower at T5 than at T1 (p=0.008), and CMJ height showed significant increase from T1 to T5 (p=0.001). Conclusion: Our results suggest that weighted plyometric exercises have an acute response on sprint, agility and counter movement jump (CMJ Height) following Post-Activation Potentiation (PAP) effect developed after plyometric exercises.

Background: Cryotherapy is a favourable treatment for post-traumatic injuries in the acute stage because of its effect on inflammation and pain. A novel cooling cuff, which can be easily used and can be wrapped around the injured area that does not require freezing, has been developed. Its efficacy compared to traditional ice therapy has not been established.Aim: To establish the effect of a cooling cuff on radial artery blood flow and lumen diameter compared to moist ice.Setting: Chiropractic clinic and radiographic laboratory.Method: A controlled laboratory pre-test post-test investigation assessed asymptomatic participants who were randomly allocated into a moist ice pack (n = 22) or the cooling cuff (n = 21) group. The intervention was placed on the participants forearm over the radial artery for 15 min. Data was collected by a qualified diagnostic radiographer using Doppler ultrasound. Data was analysed, using repeated measures analysis of variance to assess changes in blood flow and lumen diameter pre- and post-intervention. A p-value of less than 0.05 was considered significant.Results: Both groups showed a significant decrease in radial artery blood flow (p < 0.001) after 15 min with no significant changes being observed in diameter size. No significant differences were observed between the groups for radial artery blood flow or diameter.Conclusion: The cooling cuff resulted in a similar effect on radial artery blood flow and lumen diameter as moist ice, indicating that patients and practitioners may utilise the cooling cuff in the acute phases of an injury to alter blood flow.

Physician Order Entry

The multiplicity of dosing frequencies that are attached to medication orders poses a challenge to patients regarding adhering to their medication regimens and healthcare professionals in maximizing the efficiencies of health care service delivery. A multidisciplinary team project was performed to simplify medication regimens to improve the computerized physician order entry (CPOE) system to reduce the dosing frequencies for patients who were discharged from the hospital. A 36-month pre-test–post-test study was performed, including 12-month pre-intervention, 12-month intervention, and 12-month post-intervention periods. Two-pronged strategies, including regimen standardization and prioritization, were devised to evaluate the dosing frequencies and prescribing efficiency. The results showed that the standardized menu reduced the dosing frequencies from 4.3 ± 2.2 per day in the pre-intervention period to 3.5 ± 1.8 per day in the post-intervention period (p < 0.001). In addition, the proportion of patients taking medications five or more times per day decreased from 40.8% to 20.7% (p < 0.001). After prioritizing the CPOE dosing regimen, the number of pull-down options that were available reflected an improvement in the prescribing efficiency. Our findings indicate that concerted efforts in improving even a simple change on the CPOE screen via standardization and prioritization simplified the dosing frequencies for patients and improved the physicians’ prescribing process.

AbstractPurpose. Kicking, jumping and agility are important skills in football. These activities require adequate lower limb strength, which can be enhanced with resistance training. The objective of the study was to evaluate the effect of resistance tube exercises on kicking accuracy, vertical jump performance and 40-yard technical test results in competitive football players. Methods. The study involved 23 competitive football players (11 males, 12 females) aged from 18-20 years recruited from three different universities in Belgaum, Karnataka, India. Back heel kick accuracy, vertical jump height and 40-yard technical test time were evaluated before and after a 2-week resistance tube exercise program. Results. Significant improvements in post-intervention kicking accuracy were found when males and females were treated as a single group (p = 0.01). Vertical jump height also showed a highly significant post-intervention improvement in the males and for the combined group of males and females (p = 0.001). The 40-yard technical test values significantly improved in the females and in the combined results for males and females (p = 0.001). Conclusions. The two-week resistance tube exercise program was found to have an effect on kicking accuracy, vertical jump height and 40-yard technical test performance in competitive football players. Resistance tube exercises can thus be included as a component of a regular strength training program for such athletes.

The purpose of this study was to identify the effects of warm-up strategies on countermovement jump performance. Twenty-nine male college football players (age: 19.4 ± 1.1 years; body height: 179.0 ± 5.1 cm; body mass: 73.1 ± 8.0 kg; % body fat: 11.1 ± 2.7) from the Tuzla University underwent a control (no warm-up) and different warm-up conditions: 1. general warm-up; 2. general warm-up with dynamic stretching; 3. general warm-up, dynamic stretching and passive stretching; 4. passive static stretching; 5. passive static stretching and general warm-up; and, 6. passive static stretching, general warm-up and dynamic stretching. Countermovement jump performance was measured after each intervention or control. Results from one way repeated measures ANOVA revealed a significant difference on warm-up strategies at F (4.07, 113.86) = 69.56, p < 0.001, eta squared = 0.72. Bonferonni post hoc revealed that a general warm-up and a general warm-up with dynamic stretching posted the greatest gains among all interventions. On the other hand, no warm-up and passive static stretching displayed the least results in countermovement jump performance. In conclusion, countermovement jump performance preceded by a general warmup or a general warm-up with dynamic stretching posted superior gains in countermovement jump performance.

AimTo assess the utility of a multiple-encounter in-situ (MEIS) simulation as an orientation tool for multidisciplinary staff prior to opening a new paediatric emergency service.MethodsA single-group pretest/post-test study was conducted. During the MEIS simulation, multidisciplinary staff with participant or observer roles managed eight children (mannequins) who attended triage with their parent/guardians (clinical facilitators) for a range of emergency presentations (structured scenarios designed to represent the expected range of presentations plus test various clinical pathways/systems). Participants were debriefed to explore clinical, systems and crisis-resource management issues. Participants also completed a pre-intervention and post-intervention questionnaire comprising statements about role confidence and orientation adequacy. Pre-test and post-test results were analysed using t-test and Wilcoxon signed rank test.ResultsEighty-nine staff participated in the MEIS simulation, with the majority completing the pre-simulation and post-simulation questionnaire. There was a significant improvement in post-intervention versus pre-intervention Likert scores for role confidence and orientation adequacy (p=0.001 and <0.001, respectively); effect sizes suggested the greatest impact was on orientation adequacy. Nearly all scenarios resulted in significant increases in participants’ confidence levels.ConclusionsThe MEIS simulation was of utility in orientation of staff, at least with respect to self-reported role confidence and orientation adequacy. Its effectiveness in practice or compared with other orientation techniques was not assessed, but it did identify several flaws in planned systems allowing remediation prior to opening.

Vibration Training

This study investigated the effects of a short-term vibration training intervention, using a relatively low-cost side-alternating platform, on the jump performance and corresponding lower body power of a young recreationally active female population. Following institutional ethics approval, nine recreationally active females (mean: age = 21.1 ± 0.6 years; height = 1.66 ± 0.08 m; mass = 68.1 ± 9.8 kg), recruited via a convenience sampling method, were randomly assigned to a whole-body vibration training (WBVT) or control group. The WBVT group performed static squats and lunges, once-per-week over a six-week period, on a side-alternating vibration platform. The control group followed an identical training protocol without vibration exposure. Lower body muscular power was assessed pre- and post- intervention using three maximal vertical countermovement jumps (VCMJ), performed on a contact mat. Results of a repeated measures t-test revealed the WBVT group significantly improved their VCMJ performance (P= 0.012) over the six-week intervention. The control groups’ performance remained relatively stable with no significant increase in jump performance (P =0.68). The current study supports the inclusion of vibration training as part of an exercise regime to increase jumping performance and power in a recreationally active female population. As findings show comparable improvements to those from other studies following similar training protocols, using more expensive vibration platforms, further investigation is now warranted to ascertain responses to vibratory signals received from the variety of low-cost, vibration platform types currently available.

Background and Aim: The purpose of this study was to investigate the effect of jumping exercises with an overhead target on vertical jump performance of volleyball players. Method: Eighteen male volleyball players (age 21.3 ± 1.8 years, height 183.8 ± 10.0 cm, weight 78.44 ± 12.0 kg) participated in the study. The participants were divided into two groups randomly. Before the study, as a pre-test, jumping heights of all participants were measured by the Sargent method. Then, three days a week, for a total of four weeks, the control group performed 10 vertical jump exercises without targeting, while the study group performed 10 jumps with 10% more of the pretest result after the standard volleyball training. The target of a participant who reached the target three times in one session was increased by 10%. As a final test, maximal jump heights of both groups were measured again with the Sargent method. A 2X2 repeated measures analysis of variance was used to determine vertical jump height changes according to pre-test and post-test measurements of the groups.  Results: During the study, the maximal jump values ​​of the volleyball players were found to increase by 13% (55,66 ± 6,7 cm) compared to the control group (50,56 ± 7,70 cm). Conclusion: In branches such as volleyball, where jump performance is the most important determinant of success, it is suggested that exercises should be performed through an overhead target to improve vertical jump performance. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.   Özet Giriş ve Amaç: Bu çalışmanın amacı baş üstü hedef göstererek yapılan dikey sıçrama egzersizlerinin voleybol oyuncularının dikey sıçrama performansına olan etkisini araştırmaktır. Yöntem: Çalışmaya on sekiz erkek voleybol (yaş: 21,3±1,8 yıl, boy: 183,8±10,0 cm, vücut ağırlığı: 78,44±12,0 kg) oyuncusu katılmıştır. Katılımcılar rastgele yöntemle iki guruba ayrılmıştır. Çalışma öncesi tüm katılımcıların ön test olarak Sargent yöntemiyle sıçrama yükseklikleri ölçülmüştür. Daha sonra haftada üç gün, toplam dört hafta boyunca standart antrenman sonrası kontrol grubu hedef gösterilmeden 10 dikey sıçrama egzersizi yaparken, çalışma grubu ön test sonucunun %10 fazlası hedef gösterilerek 10 sıçrama çalışması yapmışlardır. Gösterilen hedefe bir çalışmada 3 defa ulaşan bir katılımcının hedefi %10 arttırılmıştır. Son test olarak her iki grubunda Sargent yöntemiyle maksimal sıçrama yükseklikleri tekrar ölçülmüştür. Grupların ön test ve son test ölçümlerine göre dikey sıçrama yükseklik değişimlerinin belirlenmesi için 2X2 tekrarlı ölçümler varyans analizi uygulanmıştır. Bulgular: Çalışma sırasında hedef göstererek (55,66±6,7 cm) yapılan egzersizlerin kontrol grubuna oranla (50,56±7,70 cm) voleybolcularda maksimal sıçrama değerlerinin daha fazla arttığı (%13) tespit edilmiştir. Tartışma-Sonuç: Voleybol gibi dikey sıçrama performansının başarının en önemli belirleyicisi olduğu branşlarda sıçrama performansının geliştirilmesi için baş üstü hedef gösterilerek yapılacak egzersizler önerilmektedir.
