“…). Although CMJ performance is not directly transferred to the dive start (11,20), our results agree with those of Zatsiorsky et al (37), who showed a correlation between flight time and the swimmer's jumping ability (r = 0.68). Similarly, Counsilman et al (13), Miyashita et al (27), and Pearson et al (28) noted a significant correlation between swim start performance and vertical jumping or leg extensor power.…”

“…Zatsiorsky et al (37) noted 2 styles of conventional start (forward and full arm swing), whereas Lewis (23) observed 3 (arms back, straight arm backswing, and circular arm backswing). According to Bowers and Cavanagh (10) and Lewis (23), the conventional start enables longer flight distances than the grab start but at the expense of a longer block phase; the conventional start was therefore advised in the relay where the block time is not necessarily incorporated into the performance time.…”

Seifert, L, Vantorre, J, Lemaitre, F, Chollet, D, Toussaint, HM, and Vilas-Boas, JP. Different profiles of the aerial start phase in front crawl. J Strength Cond Res 24(2): 507-516, 2010-This study analyzed the kinematics and kinetics (jumping ability) of the aerial start phase in 11 elite front crawl sprinters. The aim was to determine whether a particular start technique leads to a short 15 m start time or whether several start profiles contribute equally well. All swimmers performed 3 starts using their preferential style, which was the grab start for all, followed by a 25-m swim at maximal velocity. Countermovement jump enabled to determine vertical jumping ability. Using a video device, phase durations, angles at takeoff and entry, and hip velocity were assessed. Correlation between all variables and the 15 m start time established the common features of an effective start but also revealed great intersubject variability. Cluster analysis enabled to distinguish 4 start profiles (flat, pike, flight, and Volkov), indicating that several individual profiles lead to short 15 m start times. It could be advised to consider the intersubject variability in relation to start time before favoring unique strategy.

“…Conversely, the delivery phase in track and field throws ranges between 150-250 ms [3,[39][40][41]. Chronic exercise training adaptations may have increased the late RFD ability of these athletes rendering them to perform better relative to their musculature as compared to taekwondo athletes, as found in the present study.…”

“…Explosive strength may be evaluated with the rate of force development (RFD; i.e., the slope of the tangent line of the force/torque-time curve during an explosive muscle contraction [1,2]), which has been linked with explosive sports performance. Indeed, lower body isometric leg press RFD at 100, 150, 200, and 250 ms from the onset of contraction, is associated with performance in track and field throwers, where the time for the final delivery of the implement is between 150-250 ms [3]. Taekwondo is also considered to be a powerful sport.…”

Abstract:The rate of force development (RFD) is vital for power athletes. Lean body mass (LBM) is considered to be an essential contributor to RFD, nevertheless high RFD may be achieved by athletes with either high or low LBM. The aim of the study was to describe the relationship between lower-body LBM and RFD, and to compare RFD in taekwondo athletes and track and field (T&F) throwers, the latter having higher LBM when compared to taekwondo athletes. Nine taekwondo athletes and nine T&F throwers were evaluated for countermovement jumping, isometric leg press and leg extension RFD, vastus lateralis (VL), and medial gastrocnemius muscle architecture and body composition. Lower body LBM was correlated with RFD 0-250 ms (r = 0.81, p = 0.016). Taekwondo athletes had lower LBM and jumping power per LBM. RFD was similar between groups at 30-50 ms, but higher for throwers at 80-250 ms. RFD adjusted for VL thickness was higher in taekwondo athletes at 30 ms, but higher in throwers at 200-250 ms. These results suggest that lower body LBM is correlated with RFD in power trained athletes. RFD adjusted for VL thickness might be more relevant to evaluate in power athletes with low LBM, while late RFD might be more relevant to evaluate in athletes with higher LBM.

“…Other principle of movement organization which was reviewed in the study was sequential action of muscle groups and body segments. Sequential action of body segments principle in tennis strokes anticipates achievement of three strategies: 1) body segment joining the movement in the proper moment; 2) operation in the direction from proximal to distal body segments; 3) active braking of the body segments in the finish of the stroke (Hochmuth, 1964;Dyson, 1978;Lanka, 2003;Winter, 1979;Zatsiorsky et al, 1982;Ivanicevic et.al., 2011). The above consists of two mechanisms -muscle-tendon complex pre-stretch and consecutive acceleration and braking of body segments, in sports literature is called whip technique or whip mechanism (Lanka, 2003;Kopsic Segal, 2003;Ivancevic et al, 2011;Шалманов, 2002).…”

The purpose of the study was to investigate biomechanical characteristics of the forehand stroke production in adult and young tennis players, such as body segments cooperation, separation angle (x-factor) and max speed of a racquet. Kinematic data was collected with an optoelectronic motion capture system Qualisys. Participants in the experiment were 6 mid-level adult tennis players (age 19.5 ± 2.3 years, weight 66.8 ± 7.7 kg, height 170.5 ± 7.8 cm, sports experience 13.2 ± 1.7 years) and 4 young tennis players (age 11 ± 0.6 years, weight 43.5 ± 4.8 kg, height 156.3 ± 4.8 cm, sports experience 5 ± 0.5 years). The task of the motion was to carry out 3 forehand strokes for 3 times, the position of the feet and type of stance was not regulated. Results showed that racquet speed during forehand follow through phase, is significantly higher in adult players. Adult athletes have significantly higher x-factor values, which indicates that they more effectively implement muscle-tendon complex pre-stretching principle during backswing and forward swing phase. As well as adults, young tennis players also perform principle of sequential action of body segments during the stroke production, according to their technical skills and level of training.
