TL;DR: The generality of the conclusion that exercise makes people feel better is questioned by proposing that (a) occasional findings of negative affective changes tend to be discounted, (b) potentially relevant negative affectives are not always measured, and (c) examining changes from pre- to postexercise could miss negative changes during exercise.

TL;DR: Ingestion of a carbohydrate-electrolyte solution during exercise enabled subjects with compromised glycogen stores to better maintain skill and sprint performance than when ingesting fluid alone.

TL;DR: Caffeine ingestion before simulated soccer activity improved players' passing accuracy and jump performance without any detrimental effects on other performance parameters.

TL;DR: It is suggested that CHO-E ingestion improves endurance capacity during intermittent high-intensity running in subjects with high preexercise muscle glycogen concentrations and may actually be a consequence of the higher plasma glucose concentration towards the end of exercise that provided a sustained source of CHO for muscle metabolism and for the central nervous system.

TL;DR: The addition of caffeine to the carbohydrate-electrolyte solution improved sprinting performance, countermovement jumping, and the subjective experiences of players, and appeared to offset the fatigue-induced decline in self-selected components of performance.
