The effects of aerobic fitness on resistance to psychosocial stressors are reviewed. To unravel the inconsistent results in studies examining the relationship between aerobic fitness and psychosocial stress response, a meta-analysis was conducted. The results of 34 studies having 92 effect size estimates from 1,449 subjects were statistically combined to(More)
The purpose of this investigation was to determine the attentional focus patterns associated with golf putting performance. Highly skilled golfers (N = 34) were assessed using electroencephalographic (EEG) measures of the motor and temporal cortices during the 3 s prior to the golf putt. Players completed 40, 12-ft putts and performance was measured in cm(More)
Previous sport research on elite athletes has shown systematic changes in psychophysiological measures, such as heart rate (HR) deceleration and hemispheric asymmetries in EEG activity, in the few seconds prior to executing a motor response. These changes are believed to be due to a more focused attention on the external environment. Using archery (an(More)
Psychological well-being has been generally associated with vigorous aerobic activity and structured aerobic activity in adolescents and children. Low-income children are at greater risk than the general population for experiencing high environmental stress and increased mental health problems. This study investigated the effects of a structured physical(More)
The effects of smokeless tobacco (ST) on psychophysiological response and performance were examined in two studies. Study 1 compared heavy and moderate ST users on psychomotor tasks (simple reaction time/anticipation time and choice reaction time/movement time) in ST (2 g amount) and no smokeless tobacco (NST) conditions. Moderate users performed(More)
BACKGROUND The 'yips' is a psychoneuromuscular impediment affecting execution of the putting stroke in golf. Yips symptoms of jerks, tremors and freezing often occur during tournament golf and may cause performance problems. Yips-affected golfers add approximately 4.7 strokes to their scores for 18 holes of golf, and have more forearm electromyogram(More)
The purpose of the present research was to determine whether EEG biofeedback training could improve archery performance as well as self-reported measures of concentration and self-confidence. Experienced pre-elite male (N = 16) and female (N = 8) archers were randomly assigned to one of three treatment conditions: (a) correct feedback (i.e., greater left(More)

The primary purpose of the present review was to critique studies that examined the influence of psychological state (i.e., affect, perception, and cognition) on running economy (RE). However, only six studies included measures of oxygen consumption at a given workload (i.e., economy) and used running as the mode of exercise. Two of the six studies(More)
At the beginning of the twenty-first century, there are 30,000 golf courses and 55 million people who play golf worldwide. In the USA alone, the value of golf club memberships sold in the 1990s was US dollar 3.2 billion. Underpinning this significant human activity is a wide variety of people researching and applying science to sustain and develop the game.(More)
