Oxygen delivery is not a limiting factor during post-exercise recovery in healthy young adults
Conclusion The present study shows that there was no improvement in the oxygen uptake and muscle oxygenation recovery kinetics in healthy subjects under hyperoxic conditions. Slower TSI and VO2 recovery kinetics under hypoxic conditions indicate that both NIRS and spiro-ergometry are appropriate non-invasive measurement tools to assess the physiological response of a healthy individual to hypoxic exercise.

Low-load bench press and push-up induce similar muscle hypertrophy and strength gain
Conclusions Push-up exercise with similar load to 40%1RM bench press is comparably effective for muscle hypertrophy and strength gain over an 8-week training period. (Source: Journal of Exercise Science and Fitness)

Association between resting heart rate, metabolic syndrome and cardiorespiratory fitness in Korean male adults
Conclusion Resting heart rate of male adults was found to be associated with cardiorespiratory fitness; the risk factors for metabolic syndrome and relative risk of metabolic syndrome increased as resting heart rate increased. (Source: Journal of Exercise Science and Fitness)

Arterialized and venous blood lactate concentration difference during different exercise intensities
Conclusion These results suggest a delayed lactate appearance in the venous blood, which is accentuated at higher exercise intensities. The lactate measured in arterialized and venous blood is interchangeable only when blood samples are collected at least 10 minutes after the exercise starts.

The reliability and validity of a video-based method for assessing hamstring strength in football players
Conclusion The eccentric mode of the video-based hamstring strength test was a moderately reliable and valid method to measure the eccentric hamstring strength in elite football players. (Source: Journal of Exercise Science and Fitness)

Field versus race pace conditions to provoke exercise-induced bronchoconstriction in elite swimmers: Influence of training background
Conclusion All conditions have poor sensitivity to diagnose EIB and total accumulated ventilation (distance swum) did not influence AHR. These results also indicate that elite swimmers, despite many risk factors, are not limited by respiratory function in race conditions. It is proposed that the swim field test not be used for AHR assessment in swimmers due to too high relative humidity. (Source: Journal of Exercise Science and Fitness)

Associations between self-reported fitness and self-rated health, life-satisfaction and health-related quality of life among adolescents
Conclusion These findings suggest that perceived PF is associated with a better SRH, LS, and perceived HRQoL. A few implications regarding public policies were highlighted. (Source: Journal of Exercise Science and Fitness)

Effect of a moderate-intensity demonstration walk on accuracy of physical activity self-report
Conclusion A 10-minute demonstration of MVPA was associated with reporting fewer minutes of MVPA and improved agreement with objective PA measures at baseline. These findings support combining self-report PA assessments with hands-on MVPA demonstrations. (Source: Journal of Exercise Science and Fitness)

An examination of respiratory and metabolic demands of alpine skiing
Conclusion It is observed that the GS race is a high-intensity activity and that high amount of anaerobic contribution is used by alpine ski racers during the GS race. By contrast, it is understood that the aerobic contribution is also at a considerable level during such an anaerobic activity as GS. (Source: Journal of Exercise Science and Fitness)

Effect of short-term exercise intervention on cardiovascular functions and quality of life of chronic heart failure patients: A meta-analysis
Conclusions Aerobic exercise and aerobic with resistance exercise can significantly improve the aerobic capacity of CHF patients, whereas resistance exercise cannot. The improvement in aerobic capacity caused by aerobic exercise and aerobic with resistance exercise decreases with age. Systolic blood pressure and ventricle structures and functions of CHF patients show no significant changes after the short-term exercise intervention.

Gait-force model and inertial measurement unit-based measurements: A new approach for gait analysis and balance monitoring
Publication date: December 2016 Source:Journal of Exercise Science & Fitness, Volume 14, Issue 2 Author(s): Xinan Li, Hongyuan Xu, Jeffrey T. Cheung This work describes a new approach for gait analysis and balance measurement. It uses an inertial measurement unit (IMU) that can either be embedded inside a dynamically unstable platform for balance measurement or mounted on the lower back of a human participant for gait analysis. The acceleration data along three Cartesian coordinates is analyzed by the gait-force model to extract bio-mechanics information in both the dynamic state as in the gait analyzer and th...

Toward a greater understanding of the syndemic nature of hypokinetic diseases
Publication date: December 2016 Source:Journal of Exercise Science & Fitness, Volume 14, Issue 2 Author(s): Bradley J. Cardinal Physical activity participation has historically been conceptualized at the individual level with a strong emphasis on apparently healthy people. However, in the latter part of the 20th century and early part of the 21st century, a paradigm shift emerged whereby physical activity participation increasingly was acknowledged to be dependent on factors residing beyond an individual's control, with programming and intervention efforts necessary across the lifespan, in multiple settings, and...

Policies for promotion of physical activity and prevention of obesity in adolescence
Publication date: December 2016 Source:Journal of Exercise Science & Fitness, Volume 14, Issue 2 Author(s): Russell R. Pate, Jennifer I. Flynn, Marsha Dowda Obesity rates among children and adolescents in developed countries have increased dramatically since the 1970s. During that same period, numerous secular changes have combined to reduce the demand for physical activity in day-to-day life, and many barriers to physical activity are now evident. As a consequence, most children and adolescents do not meet the accepted public health guidelines for physical activity. Accordingly, public health interventions ar...

Supersets do not change energy expenditure during strength training sessions in physically active individuals
Publication date: December 2016 Source:Journal of Exercise Science & Fitness, Volume 14, Issue 2 Author(s): M.A. Brentano, Daniel Umpierre, Lucas Porto Santos, André Luiz Lopes, Luiz Fernando Martins Kruel The energy expenditure (EE) in strength training (ST) is analyzed both during and after each training session. However, little information exists about the influence of strength exercises supersets on EE. We aimed to determine whether supersets of ST exercises influenced EE during and after one strength exercise session. Twenty men were randomly divided to perform either a session with grouped exercises f...
