Effects of a Reathletization protocol after ACL ligamentoplasty on performance of Algerian professional soccer player: A case study

Abstract

Purpose: this study checks the effects of the reathletization protocol following anterior cruciate ligament (ACL) reconstruction in each of the anthropometric param-eters, muscle strength and aerobic capacity. Material & Methods: we present a 12-weeks case-study account for an Algerian professional soccer player participated in this study (age: 21 years, height: 1.71 m, weight: 62.5 kg, body mass index: 21.37 and %body fat: 9.17%). Results: the authors have comparing the results recorded in measurements and tests before and after 12-weeks of reathletization protocol applied to the professional soccer player, which was intended. First: anthropometric parameters; weight increased by (+3.6 kg, +5.76%) and body mass index by (+1.23, +5.75%). % body fat had decreased by (-1.8 kg, – 19.62%). Their thigh perimeter at 10 and 15 cm from the patella had increased respectively ((injured side; at 10 cm (+4 cm, 9.75%) and at 15 cm (3cm, 6.83%)), ((healthy side; at 10 cm (+2.5 cm, 5.61%) and at 15 cm (2.5 cm, 5%)). Second: muscle strength tests increased in; Prone plank test (1.14 min, 52.77%). Countermovement jump (14.68 cm, 45.66%). Single-leg jump (healthy side; 0.57 cm, 39.04%), (healthy side; 0.1 cm, 4.76%) and Two legs jump increased by (0.43 cm, 22.63%). Third: aerobic capacity; intermittent fitness test increased in: IFT; (2.5 km/h, 14.28%) and maximal O2 consumption (5.65 mL/min/kg, 11.85%). Heart rate measurements decreased in maximum HR (10 bpm, 5.26%), and resting HR (10 bpm, 16.66%). Conclusions: after 12-weeks of reathletization protocol, the statistics values in-dicated a greater significant improvement in the performances of the soccer player. A study with larger population should be undertaken.
