During the preparation period, 35 soccer players performed an isokinetic measurement of knee flexors and extensors (60°.−1 and 180°sec.−1). 15 of these had muscular imbalances or deficits and followed a specific isokinetic training program for 2 mo., 3 times per week. After the completion of the isokinetic training program, the 35 players underwent the same isokinetic test. Significant differences were noted between the pre- and posttraining measures at both angular velocities in peak torque values, in differences from one limb to the other, and in peak torque ratios for flexors and extensors. Consequently, the application of this specific isokinetic training program can restore imbalances in knee muscle strength efficiently.

Methods: A total of 162 gymnasts (83 male and 79 female athletes) participating in the Greek artistic gymnastic championships were observed weekly for the 1999-2000 season. Results: Ninety three (61.6%) acute injuries and 58 (38.4%) overuse syndromes were recorded. The most common anatomical location was the ankle (69 cases, 45.7%), followed by the knee (40 cases, 26.5%). The rate of mild injuries was 26.6% (25 cases), that of moderate injuries was 44% (41 cases), and that of major injuries was 29% (27 cases). The incidence of injury to the ankle and knee was significantly higher in the floor exercise, especially during the landing phase, than in the other events. Conclusions: By its nature, gymnastics predisposes to acute injuries, but up to 75% are mild or moderate. Special attention should be paid to the floor exercise, especially the landing phase.

The sample consisted of 100 young soccer players, from four different soccer teams. Two teams were the experimental group, (N = 50), and two the control group (N = 50). During the competition period, the experimental group followed a proprioception training program, 2 times per week, with 20 minute sessions. The frequency and the characteristics of injuries occurred were also recorded. Balance tests on the stability system (Biodex) were performed before and after the competition period. For the balance tests repeated measures Anova was used and the results revealed significant differences between the pre and post training measures for the experimental group. Also, the results revealed an important difference between the experimental and control group in the incidence rate of the injuries. Finally, an important difference was found between the experimental and control group in moderate severity injuries. The application of a specific balance training program on healthy young soccer players can improve their proprioception and prevent low limb injuries.

OBJECTIVE The aim of the present study was to investigate the effect of half-squat training with free weights and flywheel device on isokinetic knee muscle strength for well-trained amateur soccer players. METHODS Forty eight players were randomly divided into three groups (n= 16 each): Desmotech Training group (DT), Free Weight Training group (WT) and one Control Group (CON). DT and WT performed an eight-week half-squat training program, with two sessions per week. The DT group performed training with a flywheel device. Isokinetic concentric-eccentric strength assessments of the knee extensors-flexors muscle groups were performed at different angular velocities (60, 180 and 240∘/s). RESULTS The eight-week training program improved all the isokinetic joint moment indicators examined in the DT and WT groups (p< 0.01). The DT group achieved higher performances at all the isokinetic parameters examined, however, without statistically significant differences to the WT group. CONCLUSIONS Flywheel-based exercise is an effective training method and is suggested to be used to strengthen the lower limbs of soccer players.

Thirty collegiate students with functional ankle instability were randomly divided into 2 groups. Both groups followed an intervention balance program for 6 weeks, 3 times per week, 20 minutes per session, using balance boards. One of the 2 training groups performed the exercises on the ground—the “Land” group ( n = 15), and the other in a swimming pool—the “Aquatic” group ( n = 15). Balance ability was assessed before and after the 6-week intervention program. Balance assessments included static (stability indices: total, anterior–posterior, medial–lateral) and dynamic (dynamic moving the cursor) stability tests on the Biodex Stability System (Biodex, Inc, Shirley, NY). The results showed that in both training groups balance ability of the injured leg was significantly improved after the training period. In the final measurements, no statistically significant differences between the injured and healthy limb were found. The present study indicates that the performance of balance exercises in or out of water by collegiate students with functional ankle instability improves their balance ability. Level of Evidence: Therapeutic, Level 1

Evidence, however, is limited and the optimal program has to be identified. OBJECTIVE: To investigate the effects of two post-acute supervised proprioceptive training programs in individuals with ankle sprain. METHODS: Participants were recruited from a physiotherapy center for ankle sprain rehabilitation. In a pre-post treatment, blinded-assessor design, 22 individuals were randomly allocated to a balance or a proprioceptive neuromuscular facilitation (PNF) group. Both groups received 10 rehabilitation sessions, within a six-week period. Dorsiflexion range of motion (ROM), pain, functional and balance performance were assessed at baseline, at the end of training and eight weeks after training. RESULTS: Follow-up data were provided for 20 individuals. Eight weeks after training, statistically significant (p < 0.017) improvements were found in dorsiflexion ROM and most functional performance measures for both balance and PNF groups. Eight weeks after training, significant (p < 0.017) improvements in the frontal plane balance test and pain were observed for the balance group. CONCLUSIONS: Balance and PNF programs are recommended in clinical practice for improving ankle ROM and functional performance in individuals with sprain. Balance programs are also recommended for pain relief.
