Walk-through angina dates back more than 200 years. It was first described in a letter to the British physician, William Heberden. The term is used to describe patients with ischemic heart disease who have reduced symptoms after an episode of angina. It is related to ‘‘warm up’’ angina or, when playing golf, ‘‘first hole’’ angina. The mechanisms responsible for warm up angina are not yet clear,...

The purpose of this case series was to test the effectiveness of an active warm-up for recreational golfers using a whole-body vibration (WBV) platform. The variables that the warm-up tested for were increased flexibility, power, and golf performance. Ten adult men (age: 45 ± 15 yr) volunteered to perform their personal warm-up and record 7 of their golf swings. They then participated in an act...

PURPOSE Soccer referees' physical match performances at the start of the second half (46-60 min) were evaluated in relation to both the corresponding phase of the first half (0-15 min) and players' performances during the same match periods. METHODS Match analysis data were collected (Prozone, UK) from 12 soccer referees on 152 English Premier League matches during the 2008/09 soccer season. ...

Purpose. To examine the effects of static and proprioceptive neuromuscular facilitation (PNF) stretching of the shoulder internal rotators on throwing velocity. Subjects. 27 male throwers (mean age = 25.1 years old, SD = 2.4) with adequate knowledge of demonstrable throwing mechanics. Study Design. Randomized crossover trial with repeated measures. Methods. Subjects warmed up, threw 10 pitches ...

AIM The interaction between running, stretching and practice jumps during warm-up for jumping tests has not been investigated. The purpose of the present study was to compare the effects of running, static stretching of the leg extensors and practice jumps on explosive force production and jumping performance. METHODS Sixteen volunteers (13 male and 3 female) participated in five different wa...

[1] Two aspects of the onset of a warm event in the Southern Oscillation are 1) the subtropical South Pacific High is weakened in early southern winter which weakens subtropical sea level pressure (SLP) gradients, and thus reduces the trade winds and upwelling along the equator, and 2) in the months that follow, and particularly during the mature phase of the warm event during southern summer, ...

[1] Three alternate China-wide temperature composites covering the last 2000 years were established by combining multiple paleoclimate proxy records obtained from ice cores, tree rings, lake sediments and historical documents. Five periods of temperature variation can be identified: a warm stage in AD 0–240, a cold interval between AD 240 and 800, a return to warm conditions from AD 800–1400, i...

Warming up before performing rigorous physical activity is typically done to increase range of motion and improve athletic performance. Common warm-up techniques in college athletics include static stretching, proprioceptive neuromuscular facilitation (PNF) stretching, dynamic warm-ups, and sport-specific activities. However, the type of warm-up routine used in the college setting varies based ...
