Abstract

Background: Futsal is a ball game played by each of 5 people. With the aim of putting the ball into the opponent's goal. Agility and explosive power are required, plyometrics are used to increase lower body muscle power and increase explosive power by training muscles to perform more movements in a shorter time. This study aimed to determine the effects of plyometric zig-zag run and single leg speed hop exercises on increasing agility and leg muscle explosive power in futsal players. Subject and Method: This was a quasi experiments with no control group. The study was carried out in Kendal, Central Java, from May to June 2023. Total sample of 21 futsal players was selected simple random sampling. The dependent variable was leg muscle agility and explosive power. The independent variables were plyometric zig-zag run and single leg speed hop exercises. Leg muscle agility was measured using the agility t-test. Leg musce explosive power was measured using standing broad jump test. The data were tested using paired t-test. Result: Mean score of leg muscle agility after plyometric zig-zag run was faster (Mean= 9.86 sec.; SD= 0.58) than before (Mean= 10.03 sec.; SD= 0.53), p<0.001. Mean score of leg muscle explosive power after single leg speed hop exercises was higher (Mean= 217.05 cm; SD= 12.46) than before (Mean= 200.67 cm; SD= 10.89), p<0.001.Conclusion: Plyometric zig-zag run improves leg muscle agilty. Single leg speed hop exercises improves leg muscle explosive power. Keyword: exercise, plyometric, zig-zag run, single leg speed hop, agility, muscle explosive power

Abstract

Patellar tendinitis or jumper's knee is an injury due to overuse of the patellar tendon that often occurs in athletes, especially in jumping and running activities. This case study aims to evaluate the effectiveness of a combination of ultrasound therapy and exercise therapy program (eccentric, isometric, stretching, and strengthening exercises) in the management of jumper's knee sinistra in a 16-year-old female student who is active in volleyball at RSUD Hardjono Ponorogo. This research method is a case study, conducted three times a meeting in two weeks. Evaluation includes pain measurement using the Numeric Rating Scale (NRS), joint motion scope (LGS) with a goniometer, and functional ability using the Jette Scale. The results showed a decrease in motion pain from 4/10 to 1/10, tenderness from 3/10 to 0/10, and an increase in left knee LGS from 80° to 95°. In addition, there was an improvement in functional ability, especially in squatting and walking activities, although activities up and down stairs still require further training. The combination of exercise therapy and ultrasound proved effective in reducing pain, increasing joint flexibility, and improving functional ability in a case of jumper's knee sinistra.
