Antarctica is a challenging habitat for humans. A group of 6 explorers (3 women and 3 men) participated in an expedition in Antarctica. The objective was to observe the physiological acclimatization of the explorers using the following strategies: physical preparation, highcaloric nutritional intake, and the latest physiological monitoring and outdoor equipment. Anthropometric measures (dual x-ray absorptiometry), specific maximal aerobic test, maximal aerobic running speed test, submaximal aerobic cold testing, strength tests (grip strength, leg press and chin up), and endurance tests (bar suspension and chair position) were conducted pre- and post-expedition. Due to the sample size, a paired t-test was …

Intraindividual Variability And Validity In Smart Apparel Muscle Activity Measurements During Exercise In Men, Jonathan Aquino, Jenevieve L. Roper
International Journal of Exercise Science
International Journal of Exercise Science 11(7): 516-525, 2018. The purpose of the study was to compare smart apparel (SA) muscle activity measurements to surface electromyography (sEMG) muscle activity measurements during exercise, and determine if any systematic bias of the apparel exists. Thirty-five male participants (Ages 23.1±2.92 yrs, height 178±0.09 cm, mass 81.14±10.59 kg, body fat percentage 15.4±4.79%) provided informed consent for participation. During two separate exercise sessions, participants performed three sets of 12 bodyweight squats and pushups in both SA and sEMG. Conditions (sEMG or SA) were randomly counterbalanced. During sEMG, sensors were placed at selected anatomical locations on the …

A Cross-Training Program Does Not Alter Self-Reported Physical Activity Levels In Elementary School Children, Melody L. White, Matthew S. Renfrow, Richard S. Farley, Dana K. Fuller, Brandi M. Eveland-Sayers, Jennifer L. Caputo
International Journal of Exercise Science
International Journal of Exercise Science 11(5): 308-318, 2018. The purpose of the study was to examine the effects of a school-based cross-training program on body mass index (BMI), attitudes toward physical activity (ATPA), and physical activity (PA) levels of children in the 4th and 5th grades. Children (N = 118) were divided into control (n = 60) and experimental (n = 58) groups based on class availability. While the control group continued academic classes as usual, the experimental group participated in cross-training involving resistance training (RT), calisthenics, and stretching twice a week for 10 weeks. …
