Yet, studies have shown that NaHC[O.sub.3] may not only be an ergogenic, but also an ergolytic
substance (Deb et al., 2018).
It is convenient to consider BA as ergolytic
in PD patients, but given the limitations of the present study this conclusion is speculative.
Rats treated with p-CPA showed no reduction of the time to fatigue after icv administration of TRP, confirming that the ergolytic
action caused by increased central TRP was a consequence of the conversion of the amino acid to 5-HT, and excluding the direct participation of this amino acid in the modulation of fatigue (Figure 1) (12).
Controversies of antioxidant vitamins supplementation in exercise: ergogenic or ergolytic
effects in humans?
Coverage includes special topics such as maximizing one's glycogen stores before a mission and consuming ergogenic rather than ergolytic
foods, however, the focus is mostly on general foods.

Research indicates the majority of low-carbohydrate diets are potentially ergolytic
(performance decreasing) to endurance and high-intensity exercise.
Most reviews evaluating the central fatigue hypothesis suggest that BCAA is not an effective ergogenic supplement, nor is it ergolytic
. Further research is needed for better evaluation of the safety and efficacy of many of these supplements, especially focussing on their use in specific sporting situations.
They conclude, based on the best available scientific evidence, that an athlete should consider The Zone Diet to be ergolytic
, not ergogenic.
However, of the seven trials which found caffeine to be ergolytic
, or have no impact on performance, two of these utilised a low dose of caffeine (Astorino et al., 2012; Forbes et al., 2007), whereas five utilised moderate or high (>6 mg x [kg.sup.-1]) doses (Crowe et al., 2006; Glaister et al., 2012; Greer et al., 1998; Lee et al., 2012; Pruscino et al., 2008).
Physical training decreased the ergolytic
effect caused by the central administration of a 5-HT agonist, which suggests decreased sensitivity in trained animals.
