Cricket is a widely played sport, characterized by intermittent efforts with varying intensities, including persistent low intensity activity. However, it includes some high-intensity movements as well, such as bowling and batting [1]. Several physical attributes like muscular strength, endurance, speed, power, and agility affect the game. Muscle strength, power and speed are the essential components for batting, chasing the ball, running between the wickets, bowling, fielding and throwing.

Chronic exertional compartment syndrome of the lower leg accounts for approximately 75% of sports-related chronic leg pain. Nevertheless, the exact and timely recognition in athletes might pose a great challenge to sports physicians. Among a variety of possible differential diagnoses such as tenosynovitis, stress fractures, periostalgia, or popliteal artery entrapment syndrome the physician has to be able to identify the correct entity as promptly as possible.

This observational study used field tests to investigate the association between physiological parameters and rowing performance in athletes during ergometer and on-water Swiss national competitions. 25 Participants between 15 and 35 years who compete at national level were recruited among different clubs. We assessed anthropometric parameters such as weight, height, aerobic capacity during an incremental test on a rowing ergometer, anaerobic capacity during an on rowing ergometer Wingate test and lower limb strength and power during countermovement- and squat jumps.

Exercise testing in athletes and patients is an important and valuable diagnostic tool in the hand of the physician and sport scientist. A close collaboration between sport scientist and sport physician creates a win-win-win-situation for athletes and patients and professionals equally. According to the demands of the sport an incremental lactate threshold test (determination of the anaerobic threshold), testing of ­VO2max and performance at VO2max, and a testing of aerobic capacity (performance at competitional level) are the tests of choice. All tests need to be valid, reliable and sport specific. Sport specificity in testing is for practical purposes the most important.

Background: Heart rate variability (HRV) as a measure of the cardiac autonomic nervous system activity (CANA) has the potential to tailor endurance training and may contribute to the prevention of overtraining. We aimed to investigate whether there are sex differences and sex-specific reactions of the CANA to different training periods (TPs) in Swiss elite runners. Methods: Two HRV measurements (each 5 minutes supine and 5 minutes standing) per athlete were performed, the first during preparation period (PP) and the second during competition period (CP).
