“…The main aim of these studies was to evaluate the effects of varying breakfast regimes on physiological performance but a number of the studies also included some tests of mental performance. In the first experiment of the series [7], they compared the effects of four breakfast regimes: (a) a heavy breakfast, (b) a light breakfast, (c) no breakfast and (d) coffee only. Results showed that in the no-breakfast condition, there was a tendency towards slower reaction times.…”

Breakfast and Snacks: Associations with Cognitive Failures, Minor Injuries, Accidents and Stress

One strategy for examining effects of nutrients on cognitive function is to initially investigate foods that contain many different nutrients. If effects are demonstrated with these foods then further studies can address the role of specific nutrients. Breakfast foods (e.g., cereals, dairy products and fruit) provide many important nutrients and consumption of breakfast has been shown to be associated with beneficial effects on cognitive function. Isolating effects of specific constituents of breakfast has proved more difficult and it is still unclear what impact breakfast has on real-life performance. The present study provided initial information on associations between breakfast consumption and cognitive failures and accidents. A second aim was to examine associations between consumption of snacks which are often perceived as being unhealthy (chocolate, crisps and biscuits). A sample of over 800 nurses took part in the study. The results showed that frequency of breakfast consumption (varied breakfasts: 62% cereal) was associated with lower stress, fewer cognitive failures, injuries and accidents at work. In contrast, snacking on crisps, chocolate and biscuits was associated with higher stress, more cognitive failures and more injuries outside of work. Further research requires intervention studies to provide a clearer profile of causality and underlying mechanisms.

“…The trainees are under supervision for ten hours per day on six days per week, and during this time they have three daily main meals and two snacks, an arrangement which has proved in our hands as in those of several other authors (14,17,32) more satisfactory than does a smaller number of meals. There is a good deal of self-selection in the menu during training, allowance being made for individual preferences and for individual dietary measures necessary to produce an optimum weight.…”

Diet in Training and Competitions

The principles underlying the formulation of a diet for young professionals undergoing training for, and taking part in, Competition Golf are dealt with. The composition of the diet and its supplementation are outlined. The literature on the subject is reviewed, and the absence of any really helpful work among so much which is contradictory is pointed out. The reception of the diet over a three year period and its possible contribution to enhanced performance are discussed. The necessary components of such a diet are deduced in the light of experimental evidence and this experience. The importance of making the diet appetising and yet varying the calorie content to suit the underweight and the overweight individuals is stressed. The advisability of two diets is indicated; one providing long term nourishment to support heavy training, and the other for use on competition days, when physical requirements demand rapid production of glucose and psychic inhibition prevents complicated digestion, absorption and oxidation.

“…This increase may have been due to the fact that all these studies were carried out in the morning following a light breakfast. It has previously been noted that omission of breakfast caused an increase in tremor by late morning (Tuttle et al, 1949) and, in another study, fasting tended to increase finger tremor, although the increase did not reach statistical significance (Wharrad et al, 1985).…”

1. The effects of single oral doses of three beta‐adrenoceptor partial agonists (Ro 31‐1118, flusoxolol and pindolol), two beta‐adrenoceptor antagonists (propranolol and atenolol), two beta‐adrenoceptor agonists (salbutamol and prenalterol) and placebo on sleeping heart rate, quality of sleep, supine heart rate, exercise heart rate, blood pressure, forearm blood flow and finger tremor were studied in eight healthy male volunteers. 2. Sleeping heart rate was increased by Ro 31‐ 1118, flusoxolol, pindolol, salbutamol and prenalterol and decreased by propranolol and atenolol. 3. None of the drugs studied affected quality of sleep. 4. Supine heart rate was increased by flusoxolol, prenalterol and salbutamol, unaffected by Ro 31‐1118 and pindolol and reduced by propranolol and atenolol. 5. Exercise heart rate was reduced by both beta‐adrenoceptor antagonists and the three partial agonists and unaffected by salbutamol and prenalterol. 6. Systolic blood pressure was increased by Ro 31‐1118, flusoxolol, salbutamol and prenalterol, unaffected by pindolol and reduced by propranolol and atenolol. Diastolic blood pressure was reduced by salbutamol and prenalterol. 7. Forearm blood flow was increased by Ro 31‐1118, salbutamol and prenalterol, unchanged by pindolol and flusoxolol and decreased by atenolol and propranolol. 8. Finger tremor was increased by Ro 31‐1118, flusoxolol, pindolol, salbutamol, and prenalterol. 9. beta‐adrenoceptor partial agonists have different effects on the cardiovascular system and finger tremor to beta‐adrenoceptor antagonists. 10. While Ro 31‐ 1118 and flusoxolol are antagonists mainly at the beta 1‐adrenoceptor they have agonist activity at both beta 1‐ and beta 2 adrenoceptors. 11. While pindolol is a non‐selective antagonist its agonist activity is mainly at the beta 2‐adrenoceptor.
