Abstract on Acute Effects of Ammonia Inhalants on Strength and Power Performance in

The aim of the present study was to investigate the influence of ammonia inhalants on lower body power and maximal isometric strength in trained men. Twenty experienced resistance trained men (age = 26.7 ± 3.7 y; body weight = 80.59 ± 9.0 kg; body height = 179.5 ± 5.7 cm) were tested for counter movement jump power (CMJP), maximal force and rate of force development (pRFD20) expressed during an isometric mid-thigh pull (IMTP). Assessments were performed using either an ammonia salt inhalants (AI), a placebo (PL) or no inhalants (N). One-way analysis of variance (ANOVA) with repeated measures was used to compare strength and power performance between the different trials. A significant (p < 0.01) increase in pRFD20 was detected following the use of AI. No significant effects of trial were noted for CMJP and IMTP maximal force (p = 0.251 and p = 0.075, respectively). Results of the present study showed a potential ergogenic effect of AI on rate of force development (i.e, explosive force output), with a trend towards an improvement in maximal force production. The mechanism of action may be related to the stimulatory action of AI often reported by athletes as a “psyching-up” effect. The positive effect of AI on the rate of force development may represent an advantage in sports requiring high rates of force production.

Practical Implication: Ammonia salt inhalants may be helpful for increase rate of force development, but it isn’t clear if this translates to significant improvements in swimming results. Consult a healthcare professional before trying and do not attempt if pre-pubescent.
