Lower limb in the preparticipation examination (PPE)

This article described the clinical examination of the lower extremity during a pre-participation screening in regard of sports ability, presence of injuries and musculoskeletal disorders as well as predisposing risk factors for injuries and prevention. It divided into global static and dynamic testing but also isolated analysis of joint function.

Recovery strategies for football players

Recovery from intense efforts and matches demands special consideration, and recent years have seen the development of multiple new modalities which promise faster and better recovery. The world of professional football has taken notice, especially due to the repetition of matches and reduction of number of days in between for the best teams playing in the Champions League. Abd-Elbasset Abaïdia presented at the #SportSuisse2018 conference for Grégory Dupont, who was on duty with the World Cup winner French National team.

The burden of muscle injuries in youth football

Background: Muscle injuries affect up to 72% of professional soccer players within one season and there are well reviewed, but muscle injuries in youth soccer players are not widely documented. The aim of this study was to investigate incidence, localization, pathomechanism and point of time of indirect muscle injuries in youth soccer players. Methods: Prospective cohort study. 5 teams (U15, U16, U17, U18 and U21) with 110 young male football players (age 16,8 (14,3–21) years, height 174,5 (146,1–190,0) cm, weight 65,7 (35,5–84,6) kg) were monitored for 12 months. Every muscle injury was documented and monitored on a standardized evaluation score.

Correlation between RPE and blood lactate concentration in resistance training

Quantifying actual individual training intensity in resistance training is essential for athletes and trainers, but is at present only possible with methodological problems. Thus, the purpose of this article is to examine the relationship of different types of RPE (rating of perceived exertion) with blood lactate concentrations in hypertrophy training. Hereby it is possible, to deduce conclusions about the validity of the RPE-scale and different times of monitoring. In this article two studies with male subjects are presented (study 1: n=10, 23.7 ± 2.8 years; study 2: n=16, 24.9 ± 2.0 years). In both surveys, subjects had to complete 3 sets with 3 minutes of rest between sets in every exercise. Blood lactate was measured before each exercise and two minutes after the completion of each set.

The correlation between dynamic and isometric maximal strength parameters and muscle cross sectional area/volume

The aim of the study was the evaluation of the correlation between maximal strength and muscle mass depending on the kind of analysis which was used. Two different methods of strength evaluation and several morphological parameters were used. 77 male participants (age: 27,2 ± 6,6 years; body height: 179,9 ± 4,0 cm; body weight: 82,5 ± 10,4 kg) joined the study. Maximal strength was tested by measuring the isometric force (MIF) and analysing the one repetition maximum (1RM). The morphological data was captured by magnetic resonance imaging. The volume of the muscle (VOL), the biggest cross sectional area (QSMAX), the cross sectional area of the upper (QS30), middle (QS60) and lower (QS90) third of the scanned area of the arm flexors were examined.
