Brainstorming (Osborn, 1957), as an idea generating technique, is widely used in businesses and organizations despite evidence that it fails to produce more ideas than non-interacting groups (e.g., Mullen, Johnson, & Salas, 1991). Past tests of the technique employ comparisons instructed follow rules brainstorming (i.e., focus on quantity, free-wheeling, non-evaluation, piggy-backing) witho...

To understand the meaning of the lactate threshold (LT) and to test the hypothesis that endurance training augments lactate kinetics [i.e., rates of appearance and disposal (Ra and Rd, respectively, mg·kg(-1)·min(-1)) and metabolic clearance rate (MCR, ml·kg(-1)·min(-1))], we studied six untrained (UT) and six trained (T) subjects during 60-min exercise bouts at power outputs (PO) eliciting the...

During moderate exercise breathing a low inspired O(2) fraction (F(I)O(2)), arterial O(2) desaturation may depend on the fitness level. Seven trained (TM) and seven untrained men (UTM) cycled in normoxia and in hypoxia (F(I)O(2)=0.187, 0.173, 0.154, 0.13 and 0.117). We compared TM and UTM at submaximal intensities below the ventilatory threshold. Ventilatory variables were monitored and arteria...

The effects of 16 weeks of football or strength training on performance and functional ability were investigated in 26 (68.2 ± 3.2 years) untrained men randomized into a football (FG; n = 9), a strength training (ST; n = 9), or a control group (CO; n = 8). FG and ST trained 1.6 ± 0.1 and 1.5 ± 0.1 times per week, respectively, with higher (P < 0.05) average heart rate (HR) (∼140 vs 100 bpm) and...

To test the hypothesis that endurance training is associated with a decreased lipemia after a high fat meal, 16 young men [22 to 34 years old, nine of whom were trained (T) and seven of whom were untrained (UT)] were recruited. T ran greater than 30 or biked greater than 100 miles a week, while UT had been sedentary for at least the preceding 3 months. Daily caloric intake and daily caloric exp...

background: cardiovascular disease is the most common cause of death in the world. the aim of this study was to determine the effect of aerobic exercise on serum inflammatory markers in untrained middle-aged women. methods: nineteen healthy female middle-aged were selected by convenience sampling method and were randomly divided into two experimental (n=11) and control (n=8) groups. the exercis...

This essay looks at the historical significance of two APS classic papers that are freely available online: Gollnick PD, Armstrong RB, Saubert CW IV, Piehl K, and Saltin B. Enzyme activity and fiber composition in skeletal muscle of untrained and trained men. J Appl Physiol 33: 312–319, 1972 (http://jap.physiology.org/cgi/reprint/33/3/312).

Over the past 10 years, researchers have studied the effects of recreational football training as a health-promoting activity for participants across the lifespan. This has important public health implications as over 400 million people play football annually. Results from the first randomised controlled trial, published in the BJSM in January 2009, showed that football increased maximal oxygen...
