Exercise Fatigue Injury Under Sport Resistance

Abstract

Introduction Athletes are prone to local muscle fatigue due to high-intensity training and to long-term accumulation of musculoskeletal injuries. Musculoskeletal complications represent a large proportion of occupational health problems and, for this reason, have received increased attention from the sports industry. In this sense, studies on muscle fatigue should be intensified. Objective Verify muscle fatigue and injury involving the strain characteristics of lower limb joints in the eccentric and centripetal contraction of the jump. Methods A total of 691 individuals aged 20 to 40 years were selected. Fatigue was caused by active muscle contraction. The characteristic curves of active muscle contraction in different isometric, isotonic, and isokinetic training were analyzed. The degree of fatigue caused by three different sports states was tested by experimentation. The corresponding active muscle contraction characteristics were also analyzed. The potential for homeostasis at different ages was compared. Results The delay in recovery to fatigue is directly proportional to the athlete’s age. The return to post-exercise relief proportion from fatigue gradually decreases. Conclusion The experimental results showed that active muscle contraction could reduce exercise fatigue to some extent. This beneficial biochemical property of active muscle contraction is not found in people with advanced age. The findings have a guiding potential for the relief of sports fatigue. Evidence Level II; Therapeutic Studies - Investigating the result.

Stilbenes-enriched peanut sprouts alleviated physical fatigue via regulating interactions of nutrients–microbiota–metabolites revealed by multi-omics analysis

“…causing reduced skeletal muscle force production and physical fatigue. 25,28 Moreover, excessive ROS could alter oxidative-antioxidative balance (increased MDA content and decreased antioxidant enzyme activities), and under hypoxia conditions, the LD content and activity of CK and LDH would be enhanced. 29 It is commonly known that various antioxidants with antifatigue effect can regulate oxidative-antioxidative homeostasis.…”

Data-Driven Approach for Upper Limb Fatigue Estimation Based on Wearable Sensors

“…Estimating MF is relevant for applications in sports, medicine, and ergonomics [5]. In athletes, MF occurs due to high-intensity training, leading to musculoskeletal injuries and reduced motor performance [6,7]. In medicine, the MF analysis in the diagnosis of neuromuscular diseases is essential [8].…”
