Purpose: The feeling scale (FS) is a unique and underexplored scale in sport sciences that measures affective valence. FS has the potential to be used in athletic environments as a monitoring and prescription tool. We sought to examine whether FS ratings, as measured on a repetition-by-repetition basis, can predict proximity to task-failure and bar velocity across different exercises and loads. Methods: On the first day, 20 trained subjects (10 females) completed 1RM tests in the barbell bench and squat exercises and were introduced to the FS. On the following three sessions, subjects completed three sets to task-failure with either 1) 70%1RM bench-press, 2) 70%1RM squat (squat-70%), or 3) 80%1RM squat (squat-80%). Sessions were completed in a randomized, counter-balanced order. After every completed repetition, subjects verbally reported their FS ratings. Bar velocity was measured via linear position transducer. Results: FS ratings predicted failure-proximity and bar velocity in all three conditions (p<0.001, R2 range: 0.66-0.85). Specifically, a reduction of one unit in the FS corresponded to approaching task-failure by 14%, 11% and 11%, and to a reduction in bar velocity of 10%, 4% and 3%, in the bench, squat-70% and squat-80%, respectively. Conclusion: This is the first study to investigate if the FS can be used in RT environments among trained subjects, on a repetition-by-repetition basis. The results show strong predictive abilities of the FS, indicating that the scale can be used to monitor and prescribe resistance training, and that its benefits should be further explored.

This study evaluated the effects of continuous and intermittent blood flow restriction (BFR) with 70% of full arterial occlusion pressure on bar velocity during the bench press exercise against a wide range of resistive loads. Eleven strength-trained males (age: 23.5 ± 1.4 years; resistance training experience: 2.8 ± 0.8 years, maximal bench press strength – 1RM = 101.8 ± 13.9 kg; body mass = 79.8 ± 10.4 kg), performed three different testing protocols in random and counterbalanced order: without BFR (NO-BFR); intermittent BFR (I-BFR) and continuous BFR (C-BFR). During each experimental session, subjects performed eight sets of two repetitions each, with increasing loads from 20 to 90% 1RM (10% steps), and 3 min rest between each set. In the C-BFR condition occlusion was kept throughout the trial, while in the I-BFR, occlusion was released during each 3 min rest interval. Peak bar velocity (PV) during the bench press exercise was higher by 12–17% in both I-BFR and C-BFR compared with NO-BFR only at the loads of 20, 30, 40, and 50% 1RM (p < 0.001), while performance at higher loads remained unchanged. Mean bar velocity (MV) was unaffected by occlusion (p = 0.342). These results indicate that BFR during bench press exercise increases PV and this may be used as an enhanced stimulus during explosive resistance training. At higher workloads, bench press performance was not negatively affected by BFR, indicating that the benefits of exercise under occlusion can be obtained while explosive performance is not impaired.
