The Influence of Periodized Resistance Training on Recreationally Active Males with Chronic Nonspecific Low Back Pain
Bibliographic record
Abstract
The most common musculoskeletal health issue is chronic nonspecific low back pain (CLBP). CLBP increases pain and disability, which reduces quality of life (QoL). Generally, pain, disability, and QoL are improved with a moderate volume and intensity of physical activity. Recently, periodized resistance training (PRT) was shown to be effective at improving CLBP in sedentary young, middle-age, and older adults. The purpose of this study was to determine if PRT would increase strength, reduce pain and disability, and improve QoL in recreationally active, moderately trained middle- and older-age males. Forty-five male subjects were divided according to age into 1 of 3 groups: (a) middle-age exercise (ME), (b) old-age exercise (OE), or (c) control (C). All subjects suffered from CLBP and were considered to be moderately trained, participating in recreational ice hockey for 60 minutes, 2 times per wk(-1) for ∼5 months/year along with other recreational activities. The study ran for 16 weeks (3-week familiarization and 13 weeks of testing and PRT) with 5 repetition maximum testing at baseline and weeks 8 and 12. The PRT program systematically and progressively overloaded all major muscle groups (whole-body workout). The results indicate that middle- and old-age recreationally active males with CLBP respond similarly in magnitude to PRT, with improvements in all outcome measures (strength, pain, disability, QoL) across all time points of the study. Clinical significance (≥ 25%) in outcome measures was reached on most variables for the ME and OE groups. The results suggest that PRT may be effectively applied as rehabilitation for moderately trained recreational athletes with CLBP.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
