What does this research mean for the field?

Variable resistance training using chains promotes greater muscle fatigue compared to traditional training in Paralympic powerlifting athletes, while both methods positively influence biomarkers of oxidative stress and muscle damage. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Overview

Comparative trial reveals variable resistance induces greater acute fatigue but enhances torque development in Paralympic powerlifters, indicating distinct neuromuscular recovery profiles.

Key Points

To compare the acute effects of variable resistance training using chains versus traditional invariable resistance on peak torque, rate of torque development, oxidative stress biomarkers, and muscle damage in Paralympic powerlifting athletes.
Fourteen Paralympic powerlifters (N=14; age 28.00 ± 5.64 years; 1RM 141.43 ± 47.43 kg) participated in a 3-week study involving 1RM bench press familiarization followed by training sessions of 5 sets of 5 repetitions at 80% 1RM.
Outcomes including peak torque (PT), rate of torque development (RTD), oxidative stress markers (sulfhydryl), and muscle damage markers (lactate dehydrogenase) were measured pre-training, immediately post-training, and at 24 h and 48 h post-training.
Peak torque was significantly lower with chains than traditional resistance immediately post-exercise (368.48 ± 119.47 vs. 440.98 ± 116.38, p=0.022), at 24 h (420.36 ± 114.84 vs. 500.99 ± 103.67, p=0.004), and at 48 h (444.96 ± 111.25 vs. 502.90 ± 122.89, p<0.001, η2p=0.561).
Rate of torque development was significantly higher with chains than traditional training at 24 h (12,101.89 ± 5070.36 vs. 7915.32 ± 4486.39, p=0.002) and at 48 h (12,133.42 ± 6399.98 vs. 8187.01 ± 4903.53, p=0.016, η2p=0.452).
Traditional training significantly elevated sulfhydryl production from pre- to post-exercise and up to 48 h, whereas lactate dehydrogenase differed significantly between chain and traditional training only at the 24 h mark.
