These include, but not limited to, the reasons for such a test, the health condition of the participant/target, where the test is to be carried out, and whether there are sufficient personnel or equipment for the process or not (Sloth et al, 2013).
Based on these factors, the sub-maximal tests have been established to have the following benefits over the maximal procedure. It is applicable even among the elderly who cannot endure thorough strains. It is also applicable even among those of the sedentary lifestyle situations, which means it can be applied in the hospital settings without much constraints (Siconolfi et al, 1981). In addition, it can as well be used where are no highly trained personnel in the setting. It is, therefore very appropriate in situations where there are a lot of constraints on money issues, time factor, inadequate equipment, and sufficiently trained personnel. However, the procedure cannot be validly used in establishing the wholesome fitness of the individual since it only predicts the consumable oxygen at the end of the study should maximal test be carried out (McArdle et al, 2010). It cannot be used to establish long term results for the individual
