Abstract:

Compressive neoprene knee sleeves are marketed to improve performance during resistance training exercise. They have been approved for competition by several different strength sport organizations, including the International Powerlifting Federation. However, there is currently minimal research examining whether wearing commercially available neoprene knee sleeves have a positive effect on resistance training performance. PURPOSE: The purpose of this study was to determine whether wearing a commercially available neoprene knee sleeve affects number of repetitions performed, blood lactate (BL), heart rate (HR), ratings of perceived exertion (RPE), or muscle activity during a leg press exercise. METHODS: Seventeen resistance-trained individuals (eleven men and six women; age: 21.7 ± 2.9 y; mass: 74.9 ± 9.2 kg; height: 1.7 ± 0.1 m) participated in three testing sessions, with each session being separated by one week. In the first session, participants performed one repetition maximum (1RM) testing on a plate-loaded leg press machine. In sessions two and three, participants performed six sets at 80% 1RM until failure with three minutes rest between sets, either with knee sleeves (KS) or without (NS). The order of the KS and NS conditions were randomly determined for each subject. BL, RPE, and HR were collected after each set. Surface electromyography (EMG) of the vastus lateralis muscle was recorded to compare muscle activity during KS and NS conditions. The mean, max and integrated EMG (iEMG) of the middle three repetitions of every set were used for analysis. A one-way repeated measures ANOVA with Bonferroni post-hoc corrections were performed to assess the effect of knee sleeves on BL, RPE, HR, repetitions performed, and muscle activity. Significance was set at p≤0.05 and values are presented as mean ± SD. RESULTS: No significant differences were seen in total number of repetitions for all sets (p=0.3; KS 77.8 ± 35.2, NS 83.3 ± 36.1) or number of repetitions per individual set between KS and NS conditions, within participants (Set 1=KS 19.8 ± 8.8, NS 20.6 ± 10.3; Set 2=KS 15.2 ± 6.7, NS 14.4 ± 5.2; Set 3=KS 12.9 ± 5.5, NS 13.7 ± 5.6; Set 4=KS 10.9 ± 5.8, NS 12.2 ± 6.2; Set 5=KS 9.8 ± 4.9, NS 11 ± 6.3; Set 6=KS 9.6 ± 6.5, NS 11.3 ± 6.3). No significance differences were seen for BL, HR, and RPE (p≥0.05). For muscle activity, no significant differences were seen within participants (p≥0.05) for mean, max, and iEMG between KS and NS conditions. CONCLUSIONS: These results suggest wearing compressive neoprene knee sleeves has no effect on improving performance and associated variables during lower body resistance training. PRACTICAL APPLICATION: Despite their popularity, based on the results of the present study, wearing neoprene knee sleeves during high load, high volume lower body resistance training with the goal of improving performance is not supported.
