Purpose
This study aimed at investigating enjoyment, affective states (affective valence and perceived activation), and perceived exertion during acute resistance exercise with machines or free weights.
Methods
Thirty recreationally strength-trained males performed two training sessions on 2 separate days using a descending pyramid training system, one performed with three machines (chest press, shoulder press machine and leg press) and the other with three free weight exercises (bench press, front military press and squat). The Physical Activity Enjoyment Scale, the Borg Scale for Rating of Perceived Exertion, the Feeling Scale, and the Felt Arousal Scale were administered at the end of each session.
Results
Analyses revealed higher scores on all the variables when participants exercised with free weights (p < 0.001). Enjoyment was positively related to perceived exertion only in the free weight session (r = 0.45; p < 0.01). When looking at the circumplex model of affect, results showed that resistance exercise performed with free weights resulted in a pleasant activation feeling for all participants, while the machine training condition determined high-activation pleasant state for the majority but also cases of low-activation, displeasure state.
Conclusions
Resistance training with free weights resulted in increased pleasantness and activation compared with machine training. The establishment of resistance training programmes should consider, close to physiological and technical aspects, also the affective response to different modalities of exercise, particularly when the aim is improving the general fitness.
