This study aimed to assess the effects of repeated menthol mouth swilling upon strength and power performance. Nineteen (10 male) participants completed familiarisation and experimental trials of repeated menthol mouth swilling (0.1% concentration) or control (no swill) in a randomised crossover design. Participants performed an isometric mid-thigh pull (IMTP; peak and mean force; N), vertical jump (peak; cm) and six second sprint (peak and mean power; W) under each condition. Participants completed three efforts per exercise task interspersed with three-minute recoveries. Mean best values were analysed via a two-way mixed repeated measures ANOVA, and differences reported as effect sizes ± 95% confidence intervals, with accompanying descriptors and p values. Differences in peak IMTP values were unclear between familiarisation and experimental trials, and between menthol and control conditions. Mean IMTP force differed between familiarisation and control (0.51; −0.15 to 1.14; p = 0.001) and familiarisation and menthol conditions (0.50; −0.15 to 1.14; p = 0.002) by a small degree, but were unclear between control and menthol conditions. Unclear differences were also noted on vertical jump performance compared to familiarisation and between experimental conditions, with repeated six second peak and average power performance also showing unclear effects across all comparisons. We conclude that repeated menthol mouth swilling does not improve strength or power performance.

  El objetivo de esta investigación fue valorar los efectos de distintos tipos de calentamientos aplicados en escolares sobre la calidad de movimiento de las habilidades motrices y el rendimiento de salto y carrera. La metodología utilizada fue a partir de un diseño estudio cruzado aleatorizado (n=27 escolares), que incluyó tres condiciones experimentales para valorar el efecto agudo de distintos tipos de calentamiento (tradicional, basado en juegos adaptados reducidos y FIFA 11+) sobre el salto vertical, sprint en 20 metros y habilidades motoras de locomoción y control de objetos en niños y niñas. Se utilizó estadística descriptiva y comparativa a través de ANOVA de medidas repetidas y Friedman con sus pruebas post-hoc según corresponda. Los resultados muestran que todos los tipos de calentamiento mostraron diferencias significativas en sprint, salto vertical y habilidades motoras, respecto al a la condición control sin calentamiento. El calentamiento basado en juegos adaptados reducidos presentó efectos superiores que las otras modalidades en las habilidades motoras de locomoción (p< .05). Las comparaciones entre calentamientos mostraron que la intervención basada en FIFA 11+ mostró ser más eficaz en reducir el tiempo de sprint en 20 metros y aumentar la altura del salto vertical (p< .05). En conclusión, este estudio sugiere que, la selección de una estrategia adecuada basada en una diversidad de experiencias motrices como las ofrecidas por los protocolos de calentamiento FIFA11+ y de juegos adaptados reducidos podría ser clave para mejorar el rendimiento motor y la magnitud de los beneficios asociados al calentamiento.  Abstract: The objective of this research is to assess the effects of different types of warm-ups applied in schoolchildren on the quality of movement of motor skills and jumping and sprint performance. The methodology used was based on a randomized crossover study design (n = 27 schoolchildren), which included three experimental conditions to assess the acute effect of different types of warm-up (traditional, based on reduced adapted games and FIFA 11+) on the vertical jump, sprint in 20 meters and motor skills of locomotion and control of objects in children. Descriptive and comparative statistics were used through repeated measures ANOVA and Friedman with its post-hoc tests as appropriate. The results show that all types of warm-up showed significant differences in sprint, vertical jump and motor skills, compared to the control condition without warm-up. The warm-up based on reduced adapted games presented greater effects than the other modalities on the motor skills of locomotion (p <.05). Comparisons between warm-ups showed that the intervention based on FIFA 11+ was shown to be more effective in reducing sprint time by 20 meters and increasing vertical jump height (p <.05).  In conclusion, this study suggests that the selection of an appropriate strategy based on a diversity of motor experiences such as those offered by the FIFA11 + warm-up protocols and reduced adapted games could be key to improving motor performance and the magnitude of the benefits associated with warm-up.

INTRODUÇÃO: A potencialização pós ativação é o fenômeno do aumento da potência muscular quando precedido de uma atividade condicionante (AC) de força a partir de cargas de alta intensidade.OBJETIVO: Verificar o efeito agudo de três diferentes intensidades de atividade condicionante sobre o desempenho do salto vertical. MÉTODOS: Quinze homens com experiência no treinamento de força visitaram o laboratório em seis ocasiões. As duas primeiras visitas foram destinadas exclusivamente para identificar a carga de 1RM no exercício agachamento. As demais visitas foram realizadas de forma aleatória compreendendo três condições experimentais e um controle. Os procedimentos experimentais foram compostos com a AC realizada em 3 séries de 3 repetições com 20,55 ou 90% de 1RM no exercício agachamento. Tanto antes, como 10 minutos após a realização da AC, os voluntários realizaram 3 saltos verticais. Na visita controle, nenhuma AC foi realizada entre as séries de saltos. Como variável dependente, tanto a maior altura obtida (melhor desempenho) quanto a média de altura das séries de saltos foram consideradas. Após a verificação da normalidade pelo teste de Shapiro-Wilk, uma ANOVA two-way com medidas repetidas foi utilizado para verificar se havia interação ou efeito principal. O nível de significância adotado foi de p0,05.RESULTADOS: ANOVA two-way com medidas repetidas não observou interação grupo x teste (p=0,938) e nem efeito principal grupo (p=0,486) ou teste (p=0,658) quando se considerou a média dos 3 saltos. O mesmo resultado foi observado quando se avaliou o salto de melhor desempenho (p=0,582; p=0,873; p=0,119).CONCLUSÃO: Os protocolos adotados no presente estudo parecem não interferir no desempenho do salto vertical para indivíduos experientes no treinamento de força, mas não atletas. A individualidade biológica é um importante fator de influência, indicando a necessidade de testar o desempenho individual antes de prescrever este modelo de treino.ABSTRACT. Effect of conditioning contraction with different intensities on vertical jump performance.BACKGROUND: Post-activation potentiation is the phenomenon of increased muscle power when preceded by a high intensity conditioning activity (CA).OBJECTIVE: To verify the acute effect of three different intensities of conditioning activity on the vertical jump performance.METHODS: Fifteen men with strength training experience visited the laboratory on six occasions. The first two visits were intended exclusively to identify the 1RM load in the squat exercise. The other visits were carried out at random, comprising three experimental conditions and one control. The experimental procedures were composed with the CA performed in 3 sets of 3 repetitions with 20,55 or 90% of 1RM in the squat exercise. Before and 10 minutes after performing the CA, the volunteers performed 3 vertical jumps. In the control visit, no CA was performed between the sets of jumps. As a dependent variable, both the highest height obtained (best performance) and the average height of each sets of jumps were considered. After checking the normality by the Shapiro-Wilk test, a two-way ANOVA with repeated measures was used to check if there was an interaction or main effect. The level of significance was p0.05. RESULTS: Two-way ANOVA with repeated measures did not observe group x test interaction (p=0.938) and neither main group effect (p=0.486) nor test (p=0.658) when considering the average of the 3 jumps. The same result was observed when the best performance jump was evaluated (p=0.582; p=0.873; p=0.119).CONCLUSION: The protocols adopted in the present study do not seem to interfere with the vertical jump performance for individuals experienced in strength training, but not athletes. Biological individuality is an important influencing factor, indicating the need to test individual performance before prescribing this training model.

Although velocity control in resistance training is widely studied, its utilization in eliciting post-activation performance enhancement (PAPE) responses receives little attention. Therefore, this study aimed to evaluate the effectiveness of heavy-loaded barbell squats (BS) with velocity loss control conditioning activity (CA) on PAPE in subsequent countermovement jump (CMJ) performance. Sixteen resistance-trained female volleyball players participated in this study (age: 24 ± 5 yrs.; body mass: 63.5 ± 5.2 kg; height: 170 ± 6 cm; relative BS one-repetition maximum (1RM): 1.45 ± 0.19 kg/body mass). Each participant performed two different conditions: a set of the BS at 80% 1 RM with repetitions performed until a mean velocity loss of 10% as the CA or a control condition without CA (CNTRL). To assess changes in jump height (JH) and relative mean power output (MP), the CMJ was performed 5 min before and throughout the 10 min after the CA. The two-way analysis of variance with repeated measures showed a significant main effect of condition (p = 0.008; η2 = 0.387) and time (p < 0.0001; η2 = 0.257) for JH. The post hoc test showed a significant decrease in the 10th min in comparison to the value from baseline (p < 0.006) for the CNTRL condition. For the MP, a significant interaction (p = 0.045; η2 = 0.138) was found. The post hoc test showed a significant decrease in the 10th min in comparison to the values from baseline (p < 0.006) for the CNTRL condition. No significant differences were found between all of the time points and the baseline value for the CA condition. The CA used in the current study fails to enhance subsequent countermovement jump performance in female volleyball players. However, the individual analysis showed that 9 out of the 16 participants (56%) responded positively to the applied CA, suggesting that the PAPE effect may be individually dependent and should be carefully verified before implementation in a training program.

Abstract The evaluation of match officials’ neuromuscular performance is now an important consideration and the vertical jump test is considered suitable for assessing lower limb power, partly because it is directly related to refereeing. The aim of this study, therefore, was to determine the effect of soccer matches on match officials’ vertical jump performance by assessing various biomechanical variables. Eighteen field referees (FRs) and 36 assistant referees (ARs) who officiated in 18 official matches participated in this study. Before the match, at half time and immediately after the match, officials performed two countermovement jumps. Flight phase time (FT), maximum force production (MFpropulsion), time to production of maximum force (TMFpropulsion), production of maximum power (MP), maximum landing force (MFlanding) and time to stabilization (TTS) were calculated for all jumps. There was a tendency for match officials’ jumping performance to improve after matches than beforehand (FR: effect size (ES) = 0.19 ± 0.36, possibly trivial; AR: ES = 0.07 ± 0.17, likely trivial). There were also likely small and very likely moderate differences between FRs’ MP in pre-match and half-time jumps (ES = 0.46 ± 0.47) and in their pre- and post-match jumps (ES = 0.71 ± 0.48). These results indicate that refereeing soccer matches does not reduce vertical jump performance; the subsequent neuromuscular fatigue is not sufficient to affect landing technique.

Research background. Stretching is believed to enhance performance, reduce injury, and be an effective means of developing flexibility and alleviating muscular soreness (Shellock, Prentice, 1985; Brandy et al., 1997). A review of the current literature shows that the results of many studies conflict with others; some report that static stretching diminishes vertical jum (VJ) performance (Cornwell et al., 2001; McNeal, Sands, 2003; Wallmann et al., 2005), whereas others report that static stretching has no effect at all on VJ (Church et al., 2001; Power et al., 2004; Unick et al., 2005). Research aim, was to examine the effects of different durations of stretching on performance and to find the stretching durations that affect the performance negatively or positively. Research methods. The subjects of the study were 27 rhythmic gymnasts with the mean age of 10.00 ± 1.2 years. The subjects as a whole group participated in two different stretching programs on nonconsecutive days to eliminate the effect of individual differences on the performance. On the first day, athletes were asked to warm up by 5 minute jogging after the pretest was administered. The posttest measured the vertical jump performance after athletes stayed inactive for 20 minutes. They rested for a day and on the third day, their performance was measured again. After the 5 minute warm-up period, 10 repetitions of 15 seconds static stretching exercises for hip flexor, hamstring and gastrocnemius muscle groups were followed by the posttest. Moreover, on the fifth day 30-second exercises were repeated five times on the same type of muscles. The participants in this investigation were tested in individual vertical jump performances following warm-up only, warm-up plus 15 seconds static stretching, and warm-up plus 30 seconds. Research results. Results of a one-way repeated-measures ANOVA indicated a nonsignificant difference for vertical jump performance (F = 2.052; p > 0.05). Discussion and conclusions. Stretching exercises are referred in rhythmic gymnastics more intensively than other sports. Relevant literature displays fewer stretching repetitions and durations. These durations and repetitions may not be realistic and practical for rhythmic gymnasts. Therefore, the durations and repetitions utilized in this study are considered more appropriate for rhythmic gymnastics trainings. Rhythmic gymnasts may make use of duration and repetitions determined in this study that will not affect their performance.Keywords: anaerobic power, gymnastics, exercise.

The importance of vertical jump in sport fields and rehabilitation is widely recognized. Furthermore, Force-Time variables of vertical jump are factors affecting jumping height. Exclusive review of each of this variables, in eccentric and concentric phases, can lead to a specific focus on them during jumping exercises. So, the aims of his study were to a) reviewing the relationship between force-time curve variables of eccentric and concentric phases with jump height and b) description of this variables in Iran national youth volleyball players society. This is an observational study. 12 elite volleyball player (Male, Iran national youth volleyball players, 17&plusmn;0.7 years) have participated in this study. Correlation between Force-Time variables - included peak force (PF), relative peak force (RPP), peak power (PP), average power (AP), relative peak power (RPP), and Modified Reactive Strength Index (MRSI) - in eccentric and concentric phases and ultimate jump height has been studied. Results showed that the average power (r=0.7) and relative peak force (r=0.75) of concentric phase and MRSI (r=0.83) have significant correlation with ultimate jump height (JH). Relative peak power and average power of concentric phase can massively effect Jump Height in sports like volleyball, which vertical jump is an integral part of them. Focus on both of these factors, which has been studied in this research, in training programs, can improve athlete jump performance significantly.

Purpose: The aim of this study was to examine the effects of 2 weeks of creatine hydrochloride (CrHCl) supplementation on physical performance and hormonal changes in army soldiers. Materials: Eighteen male army soldiers were randomly assigned in a double-blind fashion to either a CrHCl (n=9) or placebo (Pl) (n=9) groups. CrHCl group costumed 3g of creatine per day, whereas Pl group was given dextrose. Before and after supplementation period, the subjects performed a battery of performance tests including one repletion maximum (1RM) of bench press and back squat, vertical jump (VJ) and Wingate anaerobic test. In addition, blood samples were obtained to determine changes in testosterone and cortisol concentrations per and post supplementation. Results: There were significant increases in VJ, peak and mean power, and 1RM back squat test following the 2 weeks of CrHCl supplementation (p < 0.05) without any significant change for the Pl group. In addition significant changes were observed in testosterone and cortisol concentrations from before to after supplementation in CrHCl group (p < 0.05) and compared with Pl group (p=0.001). Conclusions: In conclusion, the present study indicates that CrHCl supplementation can improve VJ, power performance, 1RM back squat and hormonal changes in army soldiers.

In volleyball, spikes, and block jumps are among the most important movements when earning points and impacting performance. Many studies have found a greater jump height after acutely augmented feedback and extrinsic focus of attention on vertical jump height. However, there are limited studies on the long-term effects of using an overhead target on volleyball-specific vertical jumps (block and spike jumps). Therefore, the aim of the current study was to investigate the effects of using an overhead target on the vertical jump heights of volleyball players. Twenty-five professional male volleyball players (age: 24.44 ± 3.78 years; height: 1.82 ± 8.79 cm; body mass: 80.96 ± 9.37 kg) were randomly assigned either to the experimental group with an overhead target (OHT) ( n = 9), group without an overhead target (WOHT) ( n = 10), or the control group ( n = 8). The OHT group performed vertical jumps with an overhead target before their regular training program, while the WOHT group completed vertical jumps without an overhead target before their regular training program. Meanwhile, the control group performed only their regular training program, which was a 5 week (3 days per week) program. All participants’ spike jump (SPJ) and block jump (BJ) results were assessed before and after the intervention. A repeated-measures analysis of variance (3 × 2) did not reveal any significant between-group interactions for SPJ and BJ ( F = 7.32, p < 0.11 and F = 1.59, p < 0.22 respectively), but significant results were found for the time effect ( F = 96.33, p < 0.01 and F = 132.25, p < 0.01 respectively) and group × time interaction ( F = 42.59, p < 0.01 and F = 61.52, p < 0.01, respectively). While the pre- and post-tests for BJ and SPJ values did not change in the control group ( p > 0.05), both of these values increased in the OHT group (60.00 ± 5.95–67.44 ± 5.98 cm, p < 0.01 for d = 1.24 and 49.00 ± 6.74–56.22 ± 5.29 cm p < 0.01 for d = 1.19, respectively) and WOHT group (57.50 ± 4.86–60.50 ± 4.99 cm, p < 0.01 for d = 0.60 and 47.75 ± 4.65–50.25 ± 3.69 cm, p < 0.01 for d = 0.59). It has been suggested that trainers and professionals can use an overhead target to increase the BJ and SPJ heights of professional volleyball players.

Purpose: To examine the acute effects of 3 doses of caffeine on upper- and lower-body ballistic exercise performance and to explore if habitual caffeine intake affects the acute effects of caffeine ingestion on ballistic exercise performance. Methods: Twenty recreationally active male participants completed medicine-ball-throw and vertical-jump tests under 4 experimental conditions (placebo and 2, 4, and 6 mg·kg−1 of caffeine). Results: One-way repeated-measures analysis of variance (ANOVA) with subsequent post hoc analyses indicated that performance in the medicine-ball-throw test improved, compared with placebo, only with a 6 mg·kg−1 dose of caffeine (P = .032). Effect size, calculated as the mean difference between the 2 measurements divided by the pooled SD, amounted to 0.29 (+3.7%). For the vertical-jump test, all 3 caffeine doses were effective (compared with placebo) for acute increases in performance (P values .022–.044, effect sizes 0.35–0.42, percentage changes +3.7% to +4.1%). A 2-way repeated-measures ANOVA indicated that there was no significant group × condition interaction effect, suggesting comparable responses between low (≤100 mg·d−1) and moderate to high (>100 mg·d−1) caffeine users to the experimental conditions. Conclusion: Caffeine doses of 2, 4, and 6 mg·kg−1 seem to be effective for acute enhancements in lower-body ballistic exercise performance in recreationally trained male individuals. For the upper-body ballistic exercise performance, only a caffeine dose of 6 mg·kg−1 seems to be effective. The acute effects of caffeine ingestion do not seem to be affected by habitual caffeine intake; however, this requires further exploration.

Repeated Measures Design

This study used a single-blind, within-participant, counterbalanced, repeated-measures design to examine the relationship between emotional self-regulation and sport performance. Twenty competitive athletes completed four laboratory-based conditions; familiarization, control, emotion suppression, and nonsuppression. In each condition participants completed a 10-km cycling time trial requiring self-regulation. In the experimental conditions participants watched an upsetting video before performing the cycle task. When participants suppressed their emotional reactions to the video (suppression condition) they completed the cycling task slower, generated lower mean power outputs, and reached a lower maximum heart rate and perceived greater physical exertion than when they were given no self-regulation instructions during the video (nonsuppression condition) and received no video treatment (control condition). The findings suggest that emotional self-regulation resource impairment affects perceived exertion, pacing and sport performance and extends previous research examining the regulation of persistence on physical tasks. The results are discussed in line with relevant psychophysiological theories of self-regulation and fatigue and pertinent potential implications for practice regarding performance and well-being are suggested.
