Although plyometric exercises are one of the best training methods with proven effectiveness in different sports, especially in improving physical performance, no study of young women running 800m ...has been found. Therefore, this study examines the effects of plyometric exercises included in the traditional training program on the physical performance and race time of 800-m young female runners.
Twenty young female (mean age: 16.6years) 800-m run athletes voluntarily participated in this study. Athletes were randomly assigned a plyometric training group (PTG, n=10) or a traditional training group (TTG, n=10). Both TTG and PTG completed an 8-week training protocol of 70min per day each. PTG performed plyometric training on two non-consecutive days of five days, while TTG performed only traditional training for five days, Before and after the training program, the athletes conducted a series of tests including a 20-m sprint, vertical jump, and 6×35-m running anaerobic sprint test (RAST).
Both training models induced significant improvements in all parameters tested (P<0.05). PTG achieved greater improvement than TTG in vertical jump height (5% vs. 2.45%, P<0.05), explosive power (7.82% vs. 3.84%, P<0.05), anaerobic power (5.8% vs. 3.2%, P<0.05), 20-m sprint (3.47% vs 2.11%, P<0.05), and race time (1.36% vs. 0.66%). This study revealed that plyometric exercise has a more significant effect than traditional training in improving the physical performance characteristics and competition times of young female athletes running 800m.
Bien que les exercices pliométriques soient l’une des meilleures méthodes d’entraînement avec une efficacité prouvée dans différents types de sports, notamment pour améliorer les performances physiques, il n’existe à ce jour aucune étude sur les jeunes femmes courant 800m. Par conséquent, cette étude vise à examiner les effets des exercices pliométriques inclus dans le programme d’entraînement traditionnel sur la performance physique et le temps de course chez de jeunes coureuses de 800m.
Vingt jeunes femmes (âge moyen : 16,6 ans) athlètes de course de 800m ont volontairement participé à cette étude. Les athlètes ont été assignés au hasard à un groupe d’entraînement pliométrique (PTG, n=10) ou à un groupe d’entraînement traditionnel (TTG, n=10). TTG et PTG ont suivi un protocole d’entraînement de 8 semaines de 70min par jour chacun. PTG a effectué un entraînement pliométrique sur deux jours non consécutifs de cinq jours, tandis que TTG n’a effectué qu’un entraînement traditionnel pendant cinq jours. Avant et après le programme d’entraînement, les athlètes ont effectué une série de tests comprenant un sprint de 20m, un saut vertical et un test de sprint anaérobie de 6×35m (RAST).
Les deux modèles de formation ont induit des améliorations significatives dans tous les paramètres testés (p<0,05). Le PTG a obtenu une plus grande amélioration que le TTG en hauteur de saut vertical (5 % contre 2,45 %, p<0,05), la puissance explosive (7,82 % contre 3,84 %, p<0,05), la puissance anaérobie (5,8 % contre 3,2 %, p<0,05), sprint de 20m (3,47 % vs 2,11 %, p<0,05) et temps de course (1,36 % vs 0,66 %). Cette étude a révélé que l’exercice pliométrique a un effet plus significatif que l’entraînement traditionnel sur l’amélioration des caractéristiques de performance physique et des temps de compétition des jeunes athlètes féminines courant 800m.
In Unilateral (UNI) exercises are more effective than bilateral (BI) exercises in improving athletic performance is debatable.
this meta-analysis investigated the effects of UNI and BI exercises on ...different effect indicators of jump ability, sprint ability, maximal force, change of direction ability, and balance ability.
PubMed, Google Scholar, Web of science, CNKI, Proquest, Wan Fang Data.
To be eligible for inclusion in the meta-analysis, the study had to be: 1) athletes; 2) UNI training and BI training; 3) the intervention period had to be more than 6 weeks and the intervention frequency had to be more than 2 times/week; 4) the outcome indicators were jumping ability, sprinting ability, maximum strength, and change of direction and balance.
We used the random-effects model for meta-analyses. Effect sizes (standardized mean difference), calculated from measures of horizontally oriented performance, were represented by the standardized mean difference and presented alongside 95% confidence intervals (CI).
A total of 28 papers met the inclusion criteria, and Meta-analysis showed that UNI training was more effective than BI training in improving jumping ability (ES = 0.61.0.23 to 0.09; Z = 3.12,
= 0.002 < 0.01), sprinting ability (ES = -0.02, -0.03 to -0.01; Z = 2.73,
= 0.006 < 0.01), maximum strength (ES = 8.95,2.30 to 15.61; Z = 2.64,
= 0.008 > 0.05), change of direction ability (ES = -0.03, -0.06 to 0.00; Z = 1.90,
= 0.06 > 0.01) and balance ability (ES = 1.41,-0.62 to 3.44; Z = 1.36,
= 0.17 > 0.01). The results of the analysis of moderating variables showed that intervention period, intervention frequency and intervention types all had different indicators of effect on exercise performance.
UNI training has a more significant effect on jumping and strength quality for unilateral power patterns, and BI training has a more significant effect on jumping and strength quality for bilateral power patterns.
We investigated the acute effects of different whole-body vibration (WBV) interventions on the jump height ofhighly trained karate practitioners. Fifteen male karate club athletes (age: 20.0 ± 3.8 ...years; stature: 177.3 ± 4.7 cm; bodymass: 76.9 ± 11.2 kg; % body fat: 9.2 ± 4.3) performed six randomized interventions: a static half-squat (SHS); b SHSwith external loads at 30% of the body weight (SHS + 30%BW); c WBV at frequency (f) 25 Hz, and 2 mm amplitude(A) (WBV 25/2); d WBV 25/2 with external loads of 30% of the body weight (WBV 25/2 + 30% BW); e WBV at f =50 Hz, and A = 4 mm (WBV 50/4), and f WBV 50/4 with external loads of 30% of the body weight (WBV 50/4 + 30%BW). Each intervention was performed for 5 sets at 60 s/set, with a rest interval of 30 s between sets. Countermovementjump (CMJ) data were collected at 2, 4, 6, 8 and 10 min after each preconditioning intervention. Two-way repeatedmeasures ANOVA revealed a non-significant main effect of intervention F(5, 10) = 1.44, η2 = 0.42, p = 0.29) and asignificant main effect of the rest interval F(4, 11) = 3.51, η2 = 0.56, p = 0.04) on CMJ height. A rest interval of 4 minresulted in significantly higher CMJ values than a rest interval of 2 min (p = 0.031). In conclusion, utilizing a 4-min restinterval irrespective of the intervention schemes may have potential for enhancing jumping performance among highlytrained karate athletes.
Backround Problems: Circuit resistance training is a type of strength and power training mode according to short-term strength, rate of force development, and power strategy; however, priority ...maximises performance outcomes and is not used on trained and untrained resistance populations. Research Objectives: Increased performance on developing high-intensity resistance sessions and short time intervals was investigated with systematic review and meta-analysis methodology. This meta-analysis methodologic approach aimed to report popular circuit resistance training on maximal strength, rate of force development, and power able to short-time interval set-up micro-periodization. Methods: By following this way, a high-intensity resistance combination short-time interval strategy was provided between 2008 and 2023. A study using keywords of circuit resistance training, dynamic strength, explosive power, and rate of force development was conducted to explore SportDiscus, PubMed, and the and the Web of Science databases investigated in a random model meta-analysis. Findings and Results: Exploration of circuit resistance training contributed to clarifying maximise strength and power performance under probable report outcomes detected to analysis of metadologic quality risk of bias, effect size, and mean difference. Conclusion: In conclusion, circuit resistance training strategy resulted in maximising strength and power regimes, but sufficient research has not yet been carried out as a proper periodic session adapted to detect rate of force development and power combination in the literature. In addition, circuit resistance training strategic approach may be re-performed to plan strength and power.
