International Journal of Exercise Science: Conference Proceedings
Winter Warfare Training (WWT) is a critical component of military training to prepare individuals to move effectively in harsh conditions. Moving through snow and heavy terrain increases overall stress to the entire human system. PURPOSE: The purpose of this effort was to quantify the stress response during WWT to determine the level of physiological adaptation to extreme environments. METHODS: Mountain and mobility operators (age: 31.5±1.4 years; height: 71.1±0.5 inches; weight: 192.5±6.6 lbs.; body fat percentage: 18.0±5.0%) were recruited for this effort. Participants engaged in baseline laboratory metrics at their home station located in Colorado (CO) prior to WWT for one …

Critical Power (CP) represents a threshold of sustainable endurance exercise; work prime (W’) represents the amount of metabolic disturbance one is capable of enduring above CP before exhaustion. CP increases with endurance training, but it is unclear how much of this can be explained by differences in muscle mass and body mass. PURPOSE: Characterize relationship between training status and CP and W when normalized for body and muscle mass. METHODS: We recruited 23 individuals (10 untrained individuals; 7 female, 3 male age= ~23.8yrs and 13 trained individuals; 7 female, 6 male, age= ~25.8yrs). A graded VO2max …
Time Course Evaluation Of Mapk Phosphorylation To Resistance Exercise: A Systematic Review, Justin X. Nicoll, Christopher J. Lee
Time Course Evaluation Of Mapk Phosphorylation To Resistance Exercise: A Systematic Review, Justin X. Nicoll, Christopher J. Lee
International Journal of Exercise Science: Conference Proceedings
Mitogen activated protein kinases (MAPK) are intramuscular cell signaling proteins that regulate adaptations to resistance exercise (RE). The MAPKs extracellular signal-regulated kinase 1/2 (ERK1/2), c-jun N-terminal kinase (JNK), p90RSK, and p38-MAPK increase during and after RE. Despite the well-known increase in post-RE phosphorylation responses of MAPK, the time-course and pattern of their activation remains unclear and poorly described. The ability to clearly define phosphorylation patterns during recovery are limited due to the variety of RE protocols implemented and populations tested when investigating MPAK responses to RE. PURPOSE: To systematically review literature on exercise-induced phosphorylation of ERK1/2, JNK, p38-MAPK, and …

The COVID-19 pandemic created a situation that abruptly altered the life of nearly every individual, forcing them to adjust their daily habits. Adults who regularly engaged in daily physical activity, either as recreational, collegiate, or professional athletes prior to lockdowns had to subsequently adapt and change their training regimens. PURPOSE: To determine which characteristics (age, sex, education level, socioeconomic status, primary endurance sport, whether the athlete is being coached or following a training program, and prior competition medaling) of recreational, collegiate, and professional endurance athletes were associated with training changes due to COVID-19 safety restrictions. METHODS: A cross-sectional …
The Effect Of Sport-Specific Resistance Training On Athletic Performance Outcomes Of College Rodeo Athletes, Kenneth L. Bowen Jr.
The Effect Of Sport-Specific Resistance Training On Athletic Performance Outcomes Of College Rodeo Athletes, Kenneth L. Bowen Jr.
International Journal of Exercise Science: Conference Proceedings
Resistance training yields significant improvements to athletic performance outcomes among multiple sports. A sport-specific approach for resistance produces greater adaptation and transfer to various sports. However, few studies have examined the potential benefit of sport-specific resistance training for the sport of rodeo. PURPOSE: The aim of the current investigation was to assess the effect of sport-specific resistance training on athletic performance outcomes of rodeo athletes. METHODS: Seventeen college rodeo athletes (12 females; 5 males) participated in an 8-week, 3-days per week, sport-specific resistance training program. Muscle cross sectional area (CSA), mid-thigh pull maximal isometric voluntary contraction (MVC), height (HT), …
Improvement In Physical Function And Quality Of Life In Older Adults Following 4 Weeks Of Neuromuscular Electrical Stimulation, Monica A. Mendoza, Mitchell S. Kane, Nigel C. Jiwan, Kyndall P. Ramirez, Lindsay E. Kipp Ph.D, Joni A. Mettler Ph.D

Older adults often suffer from sarcopenia, the age-related loss of muscle mass and strength, which negatively impacts physical function and quality of life (QoL). Neuromuscular electrical stimulation (NMES) is frequently used in physical rehabilitation as a muscle strengthening modality; however, little research exists on QoL outcomes in response to NMES. PURPOSE: The aim of this study was to determine changes in QoL and physical function in older adults after 4 weeks of NMES. METHODS: Ten healthy, older adults participated in the study (67.8 ± 2.1 years-old). Each participant was seated on an isokinetic dynamometer with the knee positioned at 60°, …
