The elderly athlete in the sports medicine consultation

Senior sportsmen and -women still participate in great numbers in sport events, particularly in endurance sports. Among the participants of the Jungfrau Marathon 2014 were 43% of the 3046 runners older than 50 years. These persons beeing active in sports have age related sportmedical problems. With four case reports the article tries to give concrete propositions to the sportsmed physician. Some of the graphics and tables are particularly appropriate for the counselling of active seniors in sports.

Validation of an electronic jumping ability measurement device for handball specific jumps

The aim of this study was to examine the validity of the electronic jump measurement system Training TesterTM to measure team handball specific jump performance. For this reason, standing reach height and team handball jump specific reach height were determined simultaneously with the Training TesterTM and a motion capture system as criterion measure. The Training TesterTM slightly underestimated the variables of interest. This can be explained by the relative small measuring zone of the Training TesterTM in comparison to the motion capture system. However, the correlation coefficients between both measurement methods were found to be very high.

Position paper for a a strength training programmation based on demands

Strength training guidelines tend to be based on stress factors such as relative weight, repetitions, sets, rest inbetween sets, muscle action velocity and number of sessions per week. Based on the stress-strain-concept, empirical results and training experience require additional parameters related to the molecular and cellular adaptations for an effective strength training concept. In contrast to what has generally been assumed, it is notable that the individual percentage of 1-Repetition-Maximum (1 RM) is not the intensity but only a relative training load and therefore a stress factor. Intensity is referred to here as a strain factor, operationalized as the level of effort applied to a given load.

Analysis of different variants of squats based on the literature – a focus on overuse injuries an adaptations

In the science and practice of strength training it is sometimes suggested that the deep squat entails an increased injury risk of the lumbar spine and the knee joint. Avoiding deep flexion is believed to minimize the magnitude of knee joint forces. Because within the first 50° of knee flexion calculated retropatellar compressive stress is lower, execution of quarter or half squats is recommended when overuse injuries and degenerative changes of the patella-tendon-complex exist.
