Field, laboratory, sub-maximal, and maximal test evaluation

• More likely to reflect real life due to the natural setting • Makes it hard to control extraneous variables which could influence results • Not as accurate or reliable as laboratory • Harder to replicate

• Controls extraneous variables • Replication is more possible • May lack generalisability • Low external validity • Not everyone has access to be able to do laboratory experiments

• Less accurate than maximal test • Safer than maximal test • Can be used to predict VO2 max

• Relatively time consuming • High costs involved • Requires a reasonable level of fitness and not recommended for recreational athletes or people with health problems/injuries
