Indoor cycling training in rehabilitation of patients after myocardial infarction
AbstractBackgroundStandard endurance training used from the second stage of cardiac rehabilitation has many common features with indoor cycling training which is used in fitness clubs. In the study, an attempt was made to evaluate the usefulness of this form of training in a 24-day rehabilitation program for patients after myocardial infarction. The study examined a group of 64 patients (51.34  ± 8.02 years) who were divided into two groups: the IC group (32 patients aged 53.40 ± 4.31 years) with indoor cycling training instead of standard endurance training; and the ST g...

Finishing stationary cycling too early after anterior cruciate ligament reconstruction is likely to lead to higher failure
ConclusionsExtended use, minimum up to a year or even longer, of a current rehabilitation technique, namely moderate intensity low resistance stationary cycling, is recommended preferably at the end of the day. This exercise therapeutic strategy should be a supplementation to the currently used rehabilitation best practices as a knee anti-aging maintenance effort.

Absence of menstruation in female athletes: why they do not seek help
ConclusionBy informing athletes, coaches, trainers, and mentors about menstrual cycle problems in athletes, more awareness among those groups can be created. According to the athletes, more research is needed on the long-term consequences of amenorrhea in sports, to enable them to make a better assessment of their possible future health risks. Women experience a taboo on discussing menstrual problems; role models discussing the problem may help in decreasing the taboo. A multidisciplinary collaboration of health care providers may improve care around female athletes with menstrual problems. (Source: BMC Sports Science, Med...

Which assessments are used to analyze neuromuscular control by electromyography after an anterior cruciate ligament injury to determine readiness to return to sports? A systematic review
ConclusionsDespite a wide range of EMG outcome measures for neuromuscular control, none was used to decide upon return to sports in these patients. Additional studies are needed to define readiness towards RTS by assessing neuromuscular control in adult ACL patients with EMG. Further research should aim at finding reliable and valid, EMG-related variables to be used as diagnostic tool for neuromuscular control. Moreover, future studies should aim at more homogenous groups including adequately matched healthy subjects, evaluate gender separately and use sport-specific tasks.Registration The protocol for this systematic revi...

Side differences of upper quarter Y balance test performance in sub-elite young male and female handball players with different ages
ConclusionThe detection of limb asymmetry above the proposed injury-related cut-off value in younger players (13- and 14-year-olds) but not in older players (15- to 18-year-olds) may be indicative for an increased injury risk for the younger age group. Thus, prevention programs should be implemented in the handball training routine, especially for the younger ones. (Source: BMC Sports Science, Medicine and Rehabilitation)

Evaluating match running performance in elite Australian football: a narrative review
AbstractDuring Australian football (AF) matches, players are subjected to high running loads, which are intermittent in nature. There is a growing body of research that highlights factors which can both positively and negatively affect this match running performance (e.g., the total distance travelled by a player during match-play). In order to appropriately evaluate these factors, a thorough search of MEDLINE, SportDiscus and Web of Science databases was performed, with a total of 17 manuscripts included within the final evaluation. The main findings from this review highlighted that match running performance is increased...

Advancing motor rehabilitation for adults with chronic neurological conditions through increased involvement of kinesiologists: a perspective review
AbstractMany people with neurological conditions experience challenges with movement. Although rehabilitation is often provided acutely and sub-acutely following the onset of a condition, motor deficits commonly persist in the long-term and are exacerbated by disuse and inactivity. Notably, motor rehabilitation approaches that incorporate exercise and physical activity can support gains in motor function even in the chronic stages of many neurological conditions. However, delivering motor rehabilitation on a long-term basis to people with chronic neurological conditions is a challenge within health care systems, and the on...

Comparison of different symmetry indices for the quantification of dynamic joint angles
ConclusionEven for healthy individuals, small asymmetries of movements were found and presented as reference values using 3 different symmetry indices for dynamic lower limb joint angles during 3 different movements. For the quantification of symmetrical movements differences between the joints, movements, and especially their interaction, are necessary to be taken into account. Moreover, a bias between the methods should be noted. The potential for each presented symmetry index to identify pathological movements or track a rehabilitation process was shown but has to be proven in further research.Trial registration: DRKS00...
