ABSTRACT Introduction: Ballroom dancing has become popular as an exercise method that encompasses many benefits in the social aspect. However, some middle-aged and elderly dancers have suffered from injuries and other problems from dancing. The comprehensive understanding of gymnastic training to solve this problem has not yet been raised, without which no adequate means of prevention can be outlined. Objective: Study the effect of balanced aerobic training on the physical fitness of middle-aged and elderly ballroom dance practitioners. Methods: A study was conducted with 50 volunteers practicing ballroom dancing, middle-aged and elderly, divided into experimental and control groups. According to the community square dance protocol, the control group performed the dance for one hour daily. The experimental group also used the same period and technique, introducing balanced aerobic exercises. Fitness and performance data were collected before and after the intervention, analyzed, and presented statistically. Results: In the experimental group, the growth rate of the grip strength index was 28.70%, the lumbar strength index was 32.27%, the time rate in the orthostatic position was 6.28%, and the sitting forward flexion index was 6.69%. Conclusion: Compared to traditional community sports, balanced aerobics inserted into ballroom dance training showed an improvement effect on the physical and sports fitness of middle-aged and elderly women, and may also prevent the adverse effects of aging on activities of daily living, and its implementation is valid. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: Most coordination studies are conducted in stable environments, unable to realistically simulate an environment integral to the sports field. The concept of instability training applies the principles of sports physiology, combining real situations from the soccer game to improve students’ sporting ability, and has gained attention from coaches, although it still lacks scientific evidence. Objective: Study the concept of instability training by evaluating its optimization and development effects on soccer students’ motor coordination. Methods: Fifty college soccer students were selected. The students were randomly divided into experimental and control groups, without relevant statistical differences. The experiment lasted one hour daily, three times a week, for six weeks. The control group remained with the usual training while the experimental group had the instability training protocol added. Balance test results were collected with frontal and posterior lower limb support and comprehensive posterolateral scores. Changes in activity performance were also analyzed with the results collected before and after the intervention. Results: The score of the experimental group without support was increased from 101.14 ± 8.22 to 108.73 ± 8.54, higher than the control group (103.8 ± 58.11). The comprehensive score of the experimental group was from 88.85 ± 6.10 to 99.85+8.87, also higher than the control group (88.15 ± 6.43). Conclusion: The effects of instability training to optimize and develop motor coordination in soccer students proved to be superior to usual training, and its introduction into daily training is indicated for more effective promotion of students’ fitness level. Level of evidence II; Therapeutic studies: investigation of treatment outcomes.

ABSTRACT Introduction: Badminton is a sport that demands quick decision-making and abrupt changes of direction, demanding high performance in the explosive strength of the players’ lower limbs. It is believed that the exercise of resistance in the players’ lower limbs may reflect a better performance on the court. Objective: Study the lower limbs resistance exercise effects on badminton players’ performance. Methods: 24 active badminton players were selected and randomly divided into control and experimental groups. While the control group continued the practice of existing training methods, the experimental group included lower limb strength exercise, with increased lower limb resistance with an elastic band completing the lower limb resistance exercise. Results: Before the experiment, the execution time of four points at the center of gravity was 16.83 ± 0.75 s in the experimental group and 17.15 ± 0.62 s in the control group, resulting in 15.40 ± 0.21s in the experimental group and 15.82 ± 0. 48s in the control group. The hurdle test period also changed from 10.21 ± 0.65s to 10.02 ± 0.62s in the experimental group, and from 10.82 ± 0.29s to 10.46 ± 0.32s in the control group. Conclusion: The addition of lower-limb resistance training to the daily training of badminton players can effectively improve the training efficiency and fitness of its players.

ABSTRACT Introduction: Marathon running requires stretching practices to relieve fatigue after exercise. The Proprioceptive Neuromuscular Facilitation (PNF) technique is an advanced stretching technique that allows segmenting of a specific muscle group for simultaneous stretching and strengthening. Objective: This paper explores the effect of PNF stretching exercise on relieving sports fatigue after marathon races. Methods: In this paper, 160 marathon runners were selected for the experiment, and randomly divided into experimental and control groups. The experimental group performed the PNF stretching exercise, while the control group remained with traditional stretching without any new intervention. Fatigue was assessed according to the heart rate, collected before, during, and after the experiment. Results: After nine weeks of PNF stretching training, the heart rate in the experimental group changed from 65.35 to 62.46 in the morning; during training, the group’s heart rate changed from 180.79 to 173.04; after recovery, the first group’s heart rate changed from 82.88 to 81.88. In the control group, the heart rate of the group also showed changes from 65.29 to 68.86 in the morning; during training, it changed from 180.7 to 175.49; and after recovery, from 86.23 to 88.4. Conclusion: PNF stretching exercise has a positive effect on relieving sports fatigue after marathon races. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

The Proprioceptive Neuromuscular Facilitation (PNF) technique is an advanced stretching technique that allows segmenting of a specific muscle group for simultaneous stretching and strengthening. Objective: This paper explores the effect of PNF stretching exercise on relieving sports fatigue after marathon races. Methods: In this paper, 160 marathon runners were selected for the experiment, and randomly divided into experimental and control groups. The experimental group performed the PNF stretching exercise, while the control group remained with traditional stretching without any new intervention. Fatigue was assessed according to the heart rate, collected before, during, and after the experiment. Results: After nine weeks of PNF stretching training, the heart rate in the experimental group changed from 65.35 to 62.46 in the morning; during training, the group’s heart rate changed from 180.79 to 173.04; after recovery, the first group’s heart rate changed from 82.88 to 81.88. In the control group, the heart rate of the group also showed changes from 65.29 to 68.86 in the morning; during training, it changed from 180.7 to 175.49; and after recovery, from 86.23 to 88.4.

ABSTRACT Introduction: A high index of exercise tolerance is fundamental for marathon runners, indicating a good capacity to perform the exercises considering their maximum duration and workload. Objective: Evaluate the effects of resistance training with different loads on exercise tolerance of marathon runners. Methods: 120 professional long-distance runners were selected as volunteers for the experiment. Divided into experimental groups A, B and Control, the intervention had a 9-week period. The experimental groups A and B received resistance training with different loads, while the Control group did not undergo training intervention. Results: Upper limb muscle mass increased from 3.38 ± 0.18 to 3.75 ± 0.37 in group A; from 3.40 ± 0.15 to 3.66 ± 0.31 in group B; peak biceps brachii moment increased from 53.60 ± 6.27 to 62.97 ± 8.87 in group A; from 53.67 ± 5.68 to 58.48 ± 6.16 in group B; from 5. 37 ± 2.16 to 5.73 ± 2.67 in group A; from 7.21 ± 2.62 to 6.76 ± 4.36 in group B; and from 154.86 ± 19.69 to 108.30 ± 31.75 in group A; group B presented a reduction from 156.97 ± 46.13 to 116.45 ± 39.09, and the data from the control group did not change significantly. Conclusion: Resistance training with different loads in daily training can effectively improve the endurance of long-distance runners. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: Chinese martial arts constitute an integral sport, demanding high capacity and physical fitness from its athletes. It is believed that functional balance training can enhance the performance of its athletes, as it strengthens and tones the muscles, stimulating the active proprioception of the executed movements. Objective: This paper investigates the effect of balance training on martial arts athletes and its impact on the execution of complex sports movements. Methods: Under experimental control, 100 martial arts athletes were selected and divided into two groups without statistical differences to perform the experiment. The experimental group added balance training, while the control group followed the usual training script. Sports fitness indices were measured before and after the intervention for statistical analysis. Results: The data regarding the balance index of the experimental group pre was 7.00±0.52, and after the experiment, it went to 8.40±0.47; the functional indices increased from 7.50±0.55 to 8.46±0.42. No statistically relevant changes were found in the control group. Conclusion: Functional balance training can complement daily training routines for greater benefits in martial arts athletes. The improvement of active proprioception statistically increases the ability of its practitioners in the execution of complex movements. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
