“…Unfortunately, passive twitch was not measured or muscle biopsies taken in the present study in order to confirm the speculation. Malisoux et al (2006) found some evidence that SSC training could also increase the cross-bridge mechanics of fast twitch muscle fibers by reporting increased normalized peak power of type IIa muscle fibers after 8 weeks of SSC training. Whatever the mechanism, it is suggested that an increase in fascicle stiffness after training enables the tendon to utilize more elastic energy since it is the difference in stiffness between these two structures that determines the amount of lengthening on them when force is applied (Zajac 1989).…”

TG performed supervised bilateral short contact hopping training with progressively increasing training volume. Measurements were performed before the training period (BEF) as well as after 2 weeks (2W) and 11 weeks (11W) of training. During measurements the gastrocnemius medialis -muscle (GaM) fascicle and its outer Achilles tendon length changes during hopping were examined by ultrasonography together with electromyographic (EMG) activities of calf muscles, kinematics, and kinetics.Results: At 2W the ankle joint stiffness was increased by 21.0 ± 19.3 % and contact time decreased by 9.4 ± 7.8 % in TG.Thereafter, from 2-11W the jumping height increased 56.2 ± 18.1 % in TG. Simultaneously tendon forces increased 24.3 ± 19.0 % but tendon stiffness did not change. GaM fascicles shifted to shorter operating lengths after training without any changes in their length modifications during the contact phase of hopping. Normalized EMG amplitudes during hopping did not change with training.Conclusions: The present study shows that 11 weeks of hopping training improves the performance of physically active elderly men. This improvement is achieved with shorter GaM operating lengths and therefore increased fascicle stiffness and improved tendon utilization after training. Based on these results hopping training could be recommended for healthy fit elderly to retain and improve rapid force production capacity.

“…This training requires the coordination of several muscle groups to sustain precisely timed and rhythmic plyometric movements, in order to be able to involve a high-intensity concentric contraction immediately after a rapid and powerful eccentric contraction (13). Since the rope has been considered a safe, inexpensive and portable tool, jump rope training has been preferred for adolescent population (14).…”

Purpose: The aim of this study was to compare the effects of 12-week standard versus weighted jump rope training on physical fitness tests including anaerobic power, speed, agility and flexibility in female adolescent volleyball players.Methods: Twenty-five female volleyball players were recruited to the study. Participants were randomly separated into three study groups; weighted jump rope training (n=8), standard jump rope training (n=9) and control group (n=8). All participants were assessed at baseline and after 12-week training. Physical fitness was measured by using vertical jump test, 30-meter sprint test, hexagonal obstacle test, zigzag test and sit and reach test. Repeated-measures ANOVA was used for statistical analysis. Results:Comparisons showed that after 12-week training, weighted jump-rope training resulted in higher improvements in anaerobic power (p=0.03) and agility (p=0.003) when compared to control training; and higher improvement in agility when compared to standard jump rope training (p=0.001). In addition, at the end of training, speed and flexibility gains were similar in all groups (p>0.05).Discussion: Weighted jump rope training resulted in higher improvements of anaerobic power and agility in female adolescent volleyball players. The findings of the study provide basic knowledge for developing training protocols for adolescent volleyball players. Yöntemler: Yirmi beş kadın voleybol oyuncusu çalışmaya dahil edildi. Katılımcılar ağırlıklı ip atlama (n=8), standart ip atlama (n=9) ve kontrol grubu (n=8) olmak üzere 3 gruba ayrıldı. Tüm katılımcılar eğitim öncesi ve 12 haftalık eğitimin ardından tekrar değerlendirildi. Fiziksel uygunluk, dikey sıç-rama, 30 metre sprint, beşgen engel, zikzak test ve otur-uzan testleri kullanılarak değerlendirildi. İstatistiksel analizde ANOVA kullanıldı. Sonuçlar:On iki haftalık eğitimin ardından ağırlıklı ip atlama grubunda kontrol grubu ile karşılaş-tırıldığında anaerobik güç (p=0.03) ve çeviklikte (p=0.003); standart ip atlama grubu ile karşılaş-tırıldığında ise çeviklikte (p=0.001) daha fazla gelişme kaydedildi. Ayrıca, eğitim sonucunda hız ve esneklik kazanımı tüm gruplarda benzer bulundu (p> 0.05).Tartışma: Adolesan kadın voleybol oyuncularında ağırlıklı ip atlama eğitimi anaerobik güç ve çe-viklikte daha fazla kazanım ile sonuçlanmıştır. Bu çalışmanın bulguları, adolesan voleybol oyuncuları için eğitim protokolleri geliştirilmesinde temel bilgi sunmaktadır.Anahtar kelimeler: Adolesan; pliometrik egzersiz; sporcu sağlığı; voleybol.

Effects of stretching stimulation with different rates on the expression of MyHC mRNA in mouse cultured myoblasts

In vivo studies have shown that changes in the characteristics of skeletal muscle fiber are determined by type of exercise or training. These earlier studies on mechanical stimulation, however, have all employed stimulation applied at a constant intensity, and no studies appear to have investigated change with variation of intensity of stimulation. In this study, we investigated the characteristics and differentiation of myoblasts stretched at different rates. Myoblasts were stimulated at 3 different rates, and the numbers of cells and nuclei on days 1, 3, and 5 were compared. The myosin heavy chain (MyHC) mRNA expression level was also compared. We investigated expression of MyHC-perinatal to determine speed of differentiation of myoblasts, and expression of MyHC2b, 2d, and 2a to ascertain muscle cell characteristics. Counting cells and nuclei of myoblasts revealed clear promotion of differentiation with stretching. With rapid stretching, expression of MyHC-perinatal was high at first, but then showed a decrease. In terms of effect on muscle fiber characteristics, MyHC-2b, MyHC-2d, and MyHC-2a were high with rapid, medium, and slow stretching, respectively. This indicated that myoblast differentiation was promoted regardless of difference in stretching speed, with the myoblasts acquiring the muscle-fiber characteristics appropriate to each rate of stretching.Exercise and training are known to bring about changes in the characteristics of skeletal muscle fibers (26,27). Numerous studies of the human (2,3,4,12,13,17,20,24) have shown that skeletal muscle fiber characteristics change depending on the mode of exercise. Anaerobic exercise facilitates increases in fast-twitch muscle, while aerobic exercise facilitates increases in slow-twitch muscle. Studies using rats have reported that long-term low-intensity exercise increases slow-twitch muscle and decreases fast-twitch muscle (9,15). In this manner, in vivo studies in the rat and the human have shown that exercise changes muscle fiber characteristics. From the perspective of stress, severing a nerve controlling skeletal muscle not only decreases muscle weight, but also changes muscle fiber characteristics (7,14). Studies in which muscle blood flow was regulated using devices such as a tourniquet have shown that even low-intensity training caused marked muscle hypertrophy and increased muscle force (25). However, few in vitro studies have been conducted to support and clarify these findings. In vitro studies have attempted to ascertain the effects of exercise and training by applying different stimuli. The first study (18) removed cells from rat hindlimb and soleus muscle and applied electrical stimuli via a culture solution to measure expression of myosin heavy chain (MyHC) isoforms. In the second study (11), osteoblasts were compressed using glass boards to ascertain morphological and bio-
