• 1 other identifier: 00001277
• Study Type: interventional
• Target: 41

Brief Summary

The purpose of this randomized control trial is to determine the extent of muscle fatigue in the lumbar erector spinae musculature secondary to a high-intensity interval kettlebell swing protocol utilizing TMG previously published by Jay et. al in 2011.

Conditions

Exercise Training

Outcome Measures

Primary Outcomes (1)

• Tensiomyography

  Research has progressed to support the test-retest and inter-rater reliability using TMG for measurement of muscle contraction. TMG demonstrates good to excellent relative reliability(0.80-0.99) and inter-rater ICC between 0.77-0.97 Across all five TMG parameters.4-7

  Baseline, immediate after exercise, 24 hours after exercise

Study Arms (2)

Rest

NO INTERVENTION

Subjects in the control group were instructed to complete the general warm up followed by a 10-minute rest period.

Exercise

EXPERIMENTAL

The intervention group completed two-handed Russian KBSs using an interval training protocol outlined by Jay et al.10 involving 30 seconds of work followed by 30 seconds of rest for 10 total intervals. Prior to completing the intervention, participants completed a general warmup consisting of 10 non-weighted squats, 10 non-weighted dead-lifts, and 10 dowel rod shoulder flexion repetitions. Participants were instructed to perform all warm-up activities at an intensity of 70% of maximal effort using a Rate of Perceived Exertion scale(RPE).
