Heart Rate Variability, Neuromuscular and Perceptual Recovery Following Resistance Training.

We quantified associations between changes in heart rate variability (HRV), neuromuscular and perceptual recovery following intense resistance training (RT). Adult males ( = 10) with >1 year RT experience performed six sets to failure with 90% of 10 repetition maximum in the squat, bench press, and pull-down. Changes (∆) from pre- to immediately (IP), 24 and 48 h post-RT were calculated for neuromuscular performance markers (counter-movement jump peak power and mean concentric bench press and squat velocity with load corresponding to 1.

Unexpected disasters at organized sporting events: considerations in preparation and response.

Preparing for the unexpected or unusual occurrence is always a challenge. When you add large collections of athletes and spectators, that challenge is certainly magnified, and proper planning and preparation are even more critical in reducing the damage done. The aim of this article is to stimulate thought toward preparing the medical director and staff in being ready to respond to the unexpected disaster at a sporting event.

SCUBA medicine: a first-responder's guide to diving injuries.

Self-contained underwater breathing apparatus (SCUBA) diving is an ever-growing sport, and despite a myriad of technological advances to improve safety, it remains dangerous. Providers of medical care for SCUBA divers must have an understanding of diving physiology and potential medical problems that can occur. SCUBA diving also can take participants to remote areas, so being properly prepared for potential emergencies can make a significant difference.

Medical coverage for track and field events.

Providing medical coverage at a track and field event is similar to other spectator events, but there are some important differences. With simultaneous events occurring over a large area, reliable communication with quick access to all event sites is mandatory. Preparation needs to include a prearranged emergency response plan for each event.
