Randomized Controlled Trial Comparative Study Clinical Trial
Randomised, controlled walking trials in postmenopausal women: the minimum dose to improve aerobic fitness?
The American College of Sports Medicine recommends 20-60 minutes of aerobic exercise three to five days a week at an intensity of 40/50-85% of maximal aerobic power (VO(2)MAX) reserve, expending a total of 700-2000 kcal (2.93-8.36 MJ) a week to improve aerobic power and body composition. ⋯ Walking (for 24 weeks) at moderate intensity 45% to 55% of VO(2)MAX, with a total weekly energy expenditure of 1000-1500 kcal, improves VO(2)MAX and body composition of previously sedentary, non-obese, postmenopausal women. This dose of exercise apparently approaches the minimum effective dose.

Clinical Trial
Ultrasound guided sclerosis of neovessels in painful chronic Achilles tendinosis: pilot study of a new treatment.
The mechanism that causes pain in chronic Achilles tendinosis is not known. However, high resolution colour Doppler ultrasound has shown that neovascularisation may be involved. ⋯ Sclerosing neovessels appears to be an effective treatment for painful chronic Achilles tendinosis, suggesting that neovessels play a key part in causing chronic tendon pain.

The treatment of pectoralis major tendon ruptures has been the subject of much debate. The classical history of the injury is forced abduction and external rotation. ⋯ After surgery and a graduated rehabilitation programme, both men were able to return to their sporting activities. These two cases highlight the advantage of operative management in this uncommon condition.

Randomized Controlled Trial Comparative Study Clinical Trial
Identifying college athletes at risk for pathogenic eating.
To evaluate the effectiveness of a discriminant function that predicts risk of pathogenic eating in comparison with a standard self report measure (EAT) and a clinical interview. In addition, to determine the effectiveness of this discriminant function using a variety of collegiate athletes. ⋯ This information may be helpful in the development of a simple, accessible tool to identify athletes at risk of engaging in pathogenic eating behaviours.

Comparative Study
The impact of face shield use on concussions in ice hockey: a multivariate analysis.
To identify specific risk factors for concussion severity among ice hockey players wearing full face shields compared with half face shields (visors). ⋯ The use of a full face shield compared with half face shield by intercollegiate ice hockey players significantly reduced the playing time lost because of concussion, suggesting that concussion severity may be reduced by the use of a full face shield.
