ABSTRACT Introduction: Physical fitness is the athletic ability to perform physical activities safely, avoiding the risk of injuries or performance-related complications on the field. CrossFit has been an effective training method for its natural movements and integration of aerobic and anaerobic exercises. It is believed that these characteristics may benefit the physical fitness of aerobic gym athletes. Objective: Evaluate the effects of CrossFit training on the physical fitness of aerobic gymnastics athletes. Methods: A controlled experimental study involving 24 aerobic gymnastics athletes was run for 9 weeks. The athletes were divided into an experimental group with CrossFit-based training, the control group received no additional training intervention. The indices of physical fitness, motor function, and movement performance were analyzed before and after the intervention. The results of the statistical analyses were discussed. Results: Considerable variation was obtained in fitness indices in distinct groups of muscle activities: in abdominal crunches from 37.66±6.12 to 50.11±3.01; medical ball lateral throw from 8.04±1.00 to 10.80±2.21; lateral bridge from 72.60±11.40 to 113.69±14.47; the flexion in sitting position from 22.52±2.51 to 26.46±1.33; and rope climbing from 32.32±7.28 to 25.97±7.08. In functional terms, the movement response time to music was optimized from 15.38±0.36 to 13.08±0.21; and the movement performance score was increased from 72.56±2.25 to 80.91±1.02. There were no significant changes in the control group. Conclusion: CrossFit training was shown to improve the physical conditioning of aerobic gym athletes and the functional movement performance of its practitioners. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: Pilates prioritizes the control of central muscle groups, which have a strong predilection value for volleyball training. Objective: To investigate the repercussions of Pilates training on motor coordination and stability in volleyball players. Methods: 20 athletes from a female volleyball team were randomly divided between the experimental and the control groups. Pilates intervention was performed in the experimental group. The control group followed the traditional training format, finally comparing the training results after eight weeks. Results: In the flexibility index of the experimental group, the weights increased from 23,11±5,08 times to 28,02±6,42 times; the left and right axes increased from 7,74±10,13 seconds to 8,83±8,13 seconds. In terms of the stability index, the number of intervals repeated in 20 seconds increased from 35.44±0.75 to 46.45±0.91; the lateral throw of the medicine ball was increased from 59.61±16.16 meters to 78.38±16.22 meters. The range of variation of each index is more evident than that of the control group. Conclusion: Pilates training becomes superior to usual training for the improvement of coordination and stability of volleyball players. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: Despite the intrinsic benefits of sports practice, the adherence to tennis by a large part of the population without the due physical preparation apparently resulted in a high rate of knee joint injuries in tennis players, either in daily training or competitions. Objective: Prevent tennis players’ knee joint injuries by exploring ways to improve lower limb joint stability. Methods: This paper selected 50 national second-level professional tennis players and divided them into two groups. Both groups had daily tennis training, but the experimental group experienced additional lower limb flexibility exercises. Results: The tennis players in the experimental group increased their seated forward flexion from 22.19 cm to 26.96 cm, the knee joint extensor muscle strength index increased from 142.69 to 176.23, and the knee joint flexor muscle strength index increased from 93.21 to 149.28, P<0.05, with significant differences. The general stability index was changed from 0.23 to 0.20, the internal and external indices varied from 0.13 to 0.08, and the frontal and posterior indices changed from 0.13 to 0.08. Conclusion: Knee joint injuries in tennis players can be effectively combated by adding lower limb flexibility exercise protocol to daily training.

ABSTRACT Introduction: Cyclic resistance training allows that at the end of each movement cycle, all parts of the athlete’s body return to the initial position, allowing the constant repeatability of the exercise. It is believed that this activity can significantly influence the physical capacity of the lower limbs of basketball athletes. Objective: Study the effects of cyclic resistance training on basketball players’ lower limb strength and balance ability. Methods: 36 basketball players were selected and randomly divided into experimental and control groups. The experimental group received training for eight weeks combining routine training with cyclic resistance training, while the control group remained with routine training only. Relevant performance, strength, and balance data were analyzed before and after the procedure, undergoing statistical analysis and confrontation with current literature. Results: The peak flexor moment in the experimental group increased from 94.42 ± 28.20 Nm to 101.85 ± 23.30 Nm; the peak torque of the extensor muscle increased from 161.88 ± 39.16 Nm to 186.19 ± 40.29 Nm. In the balance ability test, the left lateral test increased from 68.78 ± 4.65 cm to 74.35 ± 3.29 cm, the left increased from 109.33 ± 7.22 cm to 114.65 ± 7.54 cm. The increase in the control group was small. Conclusion: Cyclic resistance training demonstrated a beneficial effect on both lower limb strength and balance in basketball athletes, and was effective in improving the physical capacity of basketball players.Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: It is believed that the stretching method by Proprioceptive Neuromuscular Facilitation (PNF) can improve functional joint flexibility through neural stimuli, resulting in more precise movements for volleyball players. Objective: Study the effect of PNF stretching exercise on shoulder joint flexibility in volleyball athletes. Methods: A total of 30 members of a university volleyball team were randomly divided into experimental and control groups. The traditional stretching method was used in the control group, while the PNF stretching method was employed in the experimental group. Data regarding the range of motion and functional quality were collected before and after the intervention for statistical analysis. Results: After eight weeks of the experiment, the left anterior flexion functional score on the shoulder flexibility index of the experimental group increased from 147.05 ± 4.95 to 160.99 ± 4.56; the right frontal flexion score increased from 150.27 ± 5.93 to 162.16 ± 4.46. Shoulder joint stability was gradually stabilized from 88.33 to 101.17. The pass functional score increased from 4.17 ± 1.93 to 18.96 ± 1.77; the overall functional performance score increased from 9.02 ± 4.04 to 23.07 ± 3.96. The control group had an increase without statistical significance. Conclusion: PNF stretching exercises can improve the shoulder joint flexibility of volleyball players.

ABSTRACT Introduction: The standardization of body movements is essential for aerobics gymnastic practitioners and motor coordination for the execution of consecutive movements of large amplitudes is strongly related to balance ability. Therefore, it is believed that balance training can positively impact motor coordination in aerobics students Objective: Explore the influences of balance training on motor coordination in aerobics students. Methods: 100 volunteers were selected as aerobics students, divided into an experimental and a control group for a 6-week experiment. The experimental group was given a balance training protocol, while the control group maintained the traditional teaching protocol. Data on functional exercises and fitness indices were collected before and after the experiment for comparison and analysis. Results: The difference in the exercise in the unipodal orthostatic position with eyes closed was 6.45, the difference in the balance test in the swallow position was 4.04, the difference in the later-forward Y balance exercise was 1.88, the later-posterior was 2.09, and posterior Y balance was 2.53. The difference between all items in the control group was small, especially the three items of frontal, lateral, posterior, and mid-posterior Y balance. Conclusion: Balance training positively affected the motor coordination of aerobics students, resulting in a statistically significant increase in all analyzed postural balance indexes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: In recent years, high-intensity interval training has become a popular tool to help maintain body composition and reduce fat mass. It is believed that its benefits may extend to female college students. Objective: Analyze the impacts of high-intensity interval training on the body composition of female college students. Methods: Thirty high school girls at a university were selected as volunteers for an 8-week experiment. Divided equally into two groups, the experimental group received high-intensity interval training while the control group followed with routine physical training. Results were collected before and after the experiment for statistical analysis. Results: The waist circumference of the experimental group was reduced from 83.74 ± 4.55 cm to 76.49 ± 4.48 cm; hip circumference was from 101.53 ± 3.01 cm to 95.26 ± 2.99 cm; and body fat from 37.29 ± 2.09 kg to 32.93 ± 1.68 kg. The body composition index's body fat content was reduced from 29.01 ± 1.31% to 28.63 ± 1.29%. In contrast, the indexes of the control group did not change statistically compared to before training. Conclusion: High-intensity interval training can effectively improve the body composition of female college students, considerably impacting body fat reduction. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
