Hamstring training involving eccentric loading is an important protective factor in hamstring injuries. However, the effect of this mode of training on lower extremity loading in landing maneuver performance is unknown. The purpose of this study was to examine variations in eccentric hamstring strength after 10-weeks training program and the possible changes in landing kinetics. Twenty five recreational female athletes were voluntarily assigned to the Nordic Hamstraing Strength Training (N = 13) or control groups (N = 12). The training group performed 10-weeks eccentric hamstring strength training program. Baseline measures of landing kinetics were collected using a force plate while strength data was evaluated using an isokinetic dynamometer. Results indicated that NHST group increased their eccentric hamstring strength (pre = 2.34 +/- 0.28, post = 2.57 +/- 0.25 Nm/kgbw; p < 0.05) after training program albeit without changes in the dynamic control ratio. There were also significant decreases in peak anterior-posterior ground reaction force (PAPGRF; pre = 1.14 +/- 0.21 BW, post = 0.85 +/- 0.27 BW; p < 0.05) and peak vertical ground reaction force (PVGRF; pre = 6.27 +/- 1.00 BW, post = 5.34 +/- 1.01 BW; p < 0.05) scores for NHST group. The present study supports the positive effect of eccentric hamstring strength in altering landing kinetics in order to decrease the applied forces.

A Multivariate Approach to Assessing Anaerobic Power Following a Plyometric Training Program
Koçak, Mehmet Settar (Ovid Technologies (Wolters Kluwer Health), 1997-01-01)
This study used a multivariate approach to assess anaerobic power in 20 athletes and 20 nonathletes undergoing 6 weeks of plyometric training, and 20 controls. A 3 x 2 mixed model MANOVA was done to analyze the pre-and posttest scores of vertical jump, 50-m dash, and Margaria-Kalamen stairclimbing test. The Group x Test interaction was significant (p < 0.001). Both groups that underwent plyometric training improved significantly (p < 0.01) on all tests of anaerobic power. Of the dependent measures, the Marg...
The Effects of Rhythm Training on Tennis Performance
Söğüt, Mustafa; Kirazcı, Sadettin (Walter de Gruyter GmbH, 2012-06-01)
Rhythm training is an integral part of sports. The purposes of the study were to analyze the effects of rhythm training on tennis performance and rhytmic competence of tennis players, to compare the improvement levels of tennis specific and general rhythm training and to examine the effects of shorter and longer tempos on rhythmic competence. Thirty university students whose mean score of International Tennis Number (ITN) was 7.3 (+/- 0.9) were divided randomly into three sub-groups: Tennis Group, General R...

Shoulder proprioception in male adolescent tennis players and controls: The effect of shoulder position and dominance
BOYAR, ALAADDİN; SALCI, YAŞAR; Koçak, Mehmet Settar; KORKUSUZ, FEZA (IOS Press, 2007-01-01)
Proprioceptive information appears to play an important role in stability and movements of shoulder joint in sporting activities especially in tennis. The purpose of this study was to measure the shoulder proprioceptive sense differences between male tennis players and control group, in sitting and standing positions. 15 young male tennis players with a mean age 14.6 +/- 0.7 years and 15 young male sedentary individuals with a mean age 14.8 +/- 0.9 years participated in this cross-sectional descriptive stud...
