现代短跑技术理论对短跑专门性练习的启示   总被引:1,自引:0,他引:1  
通过文献资料法对现代短跑技术理论中途中跑的动力来源、途中跑的屈蹬技术、途中跑的支撑阶段、心理调试在短跑技术训练中的运用、短跑的放松技术进行回顾,总结认为:途中跑中两大腿应以髋为轴进行剪绞—制动;曲蹬时重心应相对放低,着地时间要短;要系统地看待短跑专门性练习。由半高抬小步跑、折叠高摆腿、小车轮跑这三个练习手段按照其固定顺序组成跑的专门性练习组合是比较合理的。  相似文献

在针对青少年短跑运动员进行的全面身体素质教学训练中,应该经常注意柔韧性的训练。因为柔韧性在短跑中是决定动作幅度的关键因素,再加之青少年时期是人体生长发育的最佳时期,肌健、韧带、肌肉和关节等可塑性大,如此时期忽视了柔韧性练习,无疑是失败之举。短跑运动员要增大步幅,很大程度上在于加大腾空时两腿的夹角。有研究证明,运动员在腾空时两腿的夹角加大5°~7°,步幅可增加10~12厘米。因此,加强青少年短跑运动员的柔韧性练习具有重要意义。 进行柔韧性的基本练习方法为拉伸法,从形式上分动力性拉伸和静力性拉伸。这两种拉…  相似文献

Abstract

Since the turn of the 21st century, there has been a resurgence of vibration technology to enhance sport science especially for power and force development. However, vibration exercise has been trialled in other areas that are central to athlete performance such as warm-up, flexibility and sprint speed. Therefore, the aim of this review was to attempt to gain a better understanding of how acute and short-term vibration exercise may impact on warm-up, flexibility and sprint speed. The importance of warming up for sporting performance has been well documented and vibration exercise has the capability to be included or used as a standalone warm-up modality to increase intramuscular temperature at a faster rate compared to other conventional warm-up modalities. However, vibration exercise does not provide any additional neurogenic benefits compared to conventional dynamic and passive warm-up interventions. Vibration exercise appears to be a safe modality that does not produce any adverse affects causing injury or harm and could be used during interval and substitution breaks, as it would incur a low metabolic cost and be time-efficient compared to conventional warm-up modalities. Acute or short-term vibration exercise can enhance flexibility and range of motion without having a detrimental effect on muscle power, however it is less clear which mechanisms may be responsible for this enhancement. It appears that vibration exercise is not capable of improving sprint speed performance; this could be due to the complex and dynamic nature of sprinting where the purported increase in muscle power from vibration exercise is probably lost on repeated actions of high force generation. Vibration exercise is a safe modality that produces no adverse side effects for injury or harm. It has the time-efficient capability of providing coaches, trainers, and exercise specialists with an alternative modality that can be implemented for warm-up and flexibility either in isolation or in conjunction with other conventional training methods.  相似文献

Abstract

Thirty-three college men doing the toe-touch test were used as subjects to ascertain the relative contribution of the back and hamstring muscles to hip joint flexibility. The subjects, performing six tests over a 5-week period, were photographed during each of their tests. Anthropometric measurements were taken prior to testing to determine if there was any relationship to flexibility. Making use of concentric circles and marking reference points on the subject prior to testing, it was possible to ascertain the curvature of the back, the angle of straight back flexibility, and the angle of bent back flexibility.

Results indicate that the extensibility of the hamstring muscles appeared to be one of the main contributing factors to hip joint flexion, and since the warm-up did not affect the flexibility of the back, one might conclude that the back made no increased contribution to hip joint flexion, as measured in this study. There was no significant relationship to the angle of bent back flexibility.  相似文献

Abstract

The purpose of this study was to determine the effects of an absence of a warm-up, a warm-up, and a warm-up with leg-elevation recovery techniques on repeated performances of three all-out trials in the 300-yd dash. The subjects were 15 male varsity high school runners who ran a total of nine 300-yd dashes consisting of three trials of each treatment with a 20-min rest period between trials on three different testing days. Approximately two months later the same pattern of nine 300-yd dashes was administered a second time. A randomized blocks factorial design (2 × 3 × 3) was used, followed by tests for simple main effects and Tukey's HSD test. Statistically significant differences at the .05 level were found between the overall means of the two administrations, among the means between the three methods, and among the means between the three trials. A significant interaction among methods and trials was also found. Tests for simple effects coupled with Tukey's HSD test revealed that by the time trial 3 comes about, the warm-up with recovery techniques demonstrated significant superiority of performance over no warm-up.  相似文献

The aim of this study was to examine the effect of concentric warm-up exercise on eccentrically induced changes in muscle strength, range of motion, and soreness of the elbow flexors. Ten resistance-exercise naive participants performed intermittent incremental eccentric actions (42 in total) of the elbow flexor muscles of each arm to induce muscle damage. The arms of each participant were randomly assigned either to a pre-eccentric exercise warm-up involving intermittent concentric exercise (warm-up) or no prior exercise (control). Strength, range of motion, and ratings of soreness were recorded before and 1, 2, 3, 4, and 7 days after exercise. Strength, range of motion, and soreness during muscular movements changed over time (P at most 0.01; Cohen's d at least 0.51, medium). There was an interaction (P?相似文献

The purpose of this study was to determine if warm-up with baseball bats of different moments of inertia has an effect on swing pattern and bat velocity. Ten experienced baseball players (ages 20-25 years) voluntarily participated in this study. Each participant was required to complete 10 dry swings (5 warm-up and 5 postwarm-up) at maximum effort within 3 different conditions. Post warm-up was always with a standard bat (I = .27 kgm2; 83.8 cm, 9.1 N). Warm-up for Condition 1 was with the standard bat. Condition 2 required participants to warm up with a standard bat plus a 6.1 N lead donut (I = .49 kgm2, 83.8 cm, 15.6 N). Condition 3 required participants to warm up with a hollow plastic bat (I = .08 kgm2; 83.8 cm, 3.34 N). Quantitative and qualitative analyses indicated that following warm-up with the weighted bat (largest moment of inertia), swing pattern was significantly altered, and post warm-up velocity was the lowest of the three conditions.  相似文献

Abstract

The study was made to determine the effect that different warm-up exercises of varying intensities had on the speed of leg movement. The five warm-up exercises utilized were: related warm-ups of moderate and high intensities, unrelated warm-ups of moderate and high intensities, and a passive warm-up that consisted of a hot shower. The speed of leg movement was a score that was derived from three individual speed-of-leg-movement tests: one-foot tapping (measured horizontal abduction and adduction), two-foot tapping (measured flexion and extension), and leg circling (measured circumduction). The results of the study revealed that warming-up was significantly beneficial to the speed of leg movement. More specifically, the unrelated high intensity warm-up was the most beneficial to the speed of leg movement and the high intensity warm-up was more beneficial than the moderate intensity warm-up.  相似文献

Previous research has highlighted the positive effect that different warm-up protocols have on golf performance (e.g. Sorbie et al., 2016; Tilley & Macfarlane, 2012) with the design of warm-ups and programmes targeting and improving golf performance through the activation and development of specific muscle groups. This study aimed to examine the acute effects of two warm-up protocols on golf drive performance in comparison to a control condition. Using a randomised counterbalanced design over three testing sessions, twenty-three highly skilled golfers completed the control, dynamic and resistance-band warm-up conditions. Following each condition, a GC2 launch monitor was used to record ball velocity and other launch parameters of ten shots hit with the participants’ own driver. A repeated-measures ANOVA found significant increases in ball velocity (ηp2 = .217) between the control and both the dynamic and resistance-band warm-up conditions but no difference between these latter two, and a reduction in launch angle between control and dynamic conditions. The use of either a dynamic stretching or resistance-band warm-up can have acute benefits on ball velocity but golfers should liaise with a PGA Professional golf coach to effectively integrate this into their golf driving performance.  相似文献

Purpose: The purpose of this investigation was to examine the effects of a submaximal running warm-up on running performance in male endurance athletes (n = 16, Mage = 21 ± 2 years, MVO2max = 69.3 ± 5.1 mL/kg/min). Method: Endurance performance was determined by a 30-min distance trial after control and submaximal running warm-up conditions in a randomized crossover fashion. The warm-up began with 5 min of quiet sitting, followed by 6 min of submaximal running split into 2-min intervals at speeds corresponding to 45%, 55%, and 65% maximal oxygen consumption (VO2max). A 2-min walk at 3.2 km/hr concluded the 13-min warm-up protocol. For the control condition, participants sat quietly for 13 min. VO2 and heart rate (HR) were determined at Minutes 0, 5, and 13 of the pre-exercise protocol in each condition. Results: At the end of 13 min prior to the distance trial, mean VO2 (warm-up = 14.1 ± 2.2 mL/kg/min vs. control = 5.5 ± 1.7 mL/kg/min) and mean HR (warm-up = 105 ± 11 bpm vs. control = 67 ± 11 bpm) were statistically greater (p < .001) in the warm-up condition compared with the control condition. The distance run did not statistically differ (p = .37) between the warm-up (7.8 ± 0.5 km) and control (7.7 ± 0.6 km) conditions; however, effect size calculation revealed a small effect (d = 0.2) in favor of the warm-up condition. Thus, the warm-up employed may have important and practical implications to determine placing among high-level athletes in close races. Conclusions: These findings suggest a submaximal running warm-up may have a small but critical effect on a 30-min distance trial in competitive endurance athletes. Further, the warm-up elicited increases in physiological variables VO2 and HR prior to performance; thus, a submaximal specific warm-up should warrant consideration.  相似文献
