The purpose of this study was to determine and to compare characteristics of the lower limb extension musculature in Chilean indoor and beach volleyball players and the muscular contribution during the CMJ. The sample was composed by 13 subjects belonging to the Chilean elite beach and indoor volleyball. The subjects performed 3 CMJ jumps for average determination of the height of the jump, ecc...

Weightlifters produce strength and power in the vertical plane, while canoeists horizontal plane. The purpose of study is to examine difference between isometric ballistic force athletes weightlifting canoeing, at which production occurs different planes. 84 aged 14-21 were included study. Demographic information was taken on a working day standard warm-up protocol applied. Dynamic Strength Ind...

The present study examined the relationship between self-generated emotions and physical performance. All participants took part in five emotion induction conditions (happiness, anger, anxiety, sadness, and an emotion-neutral state) and we investigated their influence on the force of the finger musculature (Experiment 1), the jump height of a counter-movement jump (Experiment 2), and the veloci...

Most musculoskeletal models used to analyze human movement utilize Hill-type muscle models that account for state dependent intrinsic muscle properties (e.g., force-length-velocity relationships), but rarely do these models include history dependent effects (e.g., force depression or enhancement). While the relationship between muscle shortening and force depression can be well characterized by...

PURPOSE The aim of this study was to investigate and to compare the effect of a 12-wk period of whole-body vibration training and resistance training on human knee-extensor strength. METHODS Sixty-seven untrained females (21.4 +/- 1.8 yr) participated in the study. The whole-body vibration group (WBV, N = 18) and the placebo group (PL, N = 19) performed static and dynamic knee-extensor exerci...

Paavolainen et. al. (1991) reported that national level cross-country skiers who engaged in explosive type strength training in addition to their normal training, were able improve their force-times i.e. improve their ability to produce a given amount of force in shorter time. This was also described by a significant improvement of jump heights in both static and counter movement jumps, whereas...

Whole-body vibration (WBV) has been suggested to be particularly effective on the stretch-shortening cyclebased movements, such as the counter movement jump (CMJ) test (Issurin, 2005). Nevertheless, the literature on short-term vibration exposure and lower limb explosive performance (measured by CMJ test) is contradictory. Either transient improvements (Bosco et al., 2000; Cochrane and Stannard...

Kinesiologic elastic tape is widely used for both clinical and sport applications although its efficacy in enhancing agonistic performance is still controversial. Aim of the study was to verify in a group of healthy basketball players whether a neuromuscular taping application (NMT) on ankle and knee joints could affect the kinematic and the kinetic parameters of the jump, either by enhancing o...

While it seems that whole body vibration (WBV) might be an effective modality to enhance physical performance, the proper prescription of WBV for performance enhancement remains unknown. The purpose of this study was to compare the immediate effect of various WBV accelerations on counter movement jump (CMJ) height, the duration of any effect, and differences between men and women. Forty-four pa...

Amaç: Adölesan basketbolcularda akut nöromusküler yorgunluk (NY) durumunun ''drop'' sıçrama (DS) performansına etkisinin incelenmesi dikkate değer görünmektedir. Sunulan çalışmanın amacı; adölesan tekrarlı ''counter movement'' (CMS) modelli oluşturulan NY'nin DS incelenmesidir. Gereç ve Yöntemler: Çalışmaya 18 basketbolcu sedanter olmak üzere toplam 36 erkek gönüllü olarak katılmıştır. Katılımc...
