We evaluated the benefits and relationship of the number of steps per day to the cardiometabolic risk factors: adiposity indicators; insulin resistance; and metabolic syndrome (MetS) in apparently healthy Brazilian middle-aged men. ⋯ Brazilian middle-aged men performing more than 10,000 steps per day have better cardiometabolic conditions than those walking fewer than 10,000 steps. The number of steps per day is inversely related to the indicators of total and regional adiposity, insulin resistance and MetS.

Observational Study
The effect of transversus abdominis activation on exercise-related transient abdominal pain.
Exercise-related transient abdominal pain (ETAP) affects 40-60% of the physically active population, is detrimental to performance but of unknown aetiology. Excessive movement of abdominal peritoneum is one proposed mechanism. Transversus abdominis (TrA) function may play a role reducing in the incidence of Exercise-related transient abdominal pain via the tensioning of the thoracolumbar fascia or increasing intra-abdominal pressure. The aim of this study is to identify any relationship between transversus abdominis function and exercise-related transient abdominal pain, hypothesing that those with stronger transversus abdominis will have lower incidence of exercise-related transient abdominal pain. ⋯ Participants who had stronger trunk muscles and larger resting Transversus abdominis size experienced Exercise-related transient abdominal pain less.

Review Meta Analysis
Exercise and the treatment of depression: a review of the exercise program variables.
There is growing interest in the use of exercise in the treatment of depression. A number of randomized controlled trials (RCTs) have demonstrated a reduction in depressive symptoms with both aerobic and non-aerobic exercise interventions. This has been supported in a number of systematic reviews and meta-analyses. However, the heterogeneous nature of the exercise intervention trials makes determining the appropriate program variables (frequency, intensity, duration and type of exercise) difficult. ⋯ There is evidence for the use supervised aerobic exercise, undertaken three times weekly at moderate intensity for a minimum of nine weeks in the treatment of depression. Further research on the manipulation of program variables is warranted.

Achilles tendon pathology (ATP) is a multifactorial condition for which genetic risk factors have been identified. The ADAMTS, ADAM12 and TIMP2 genes encode enzymes that are important regulators of tendon homeostasis. ADAMTS2 and ADAMTS14 proteins are procollagen N-propeptidases for pro-collagen type I, type II, and type III. ADAMTS2, like COL5A1, has been linked to Ehlers-Danlos syndrome. Variants within ADAMTS5 and ADAM12 have been associated with osteoarthritis. TIMP2, a metalloprotease inhibitor, maintains homeostasis in the ECM by inhibiting ADAM, ADAMTS and MMP functions. We sought to determine whether single nucleotide polymorphisms (SNPs) within the ADAMTS2, ADAMTS5, ADAMTS14, ADAM12 and TIMP2 genes were associated with the risk of ATP in two independent populations. ⋯ Our data show that DNA sequence variation within the TIMP2 gene is a risk factor for ATP in Caucasians. Furthermore, carriage of the ADAMTS14 rs4747096 GG variant appears to delay onset of the injury in the ATP group.
