Effects of ambient particulate matter on aerobic exercise performance
ConclusionAn acute bout of vigorous exercise during an AQI of “yellow” did not diminish exercise performance in healthy adults, nor did it have a negative effect on pulmonary function or biological health markers. These variables might not be sensitive to small changes from acute, mild PM2.5 exposure. (Source: Journal of Exercise Science and Fitness)

Influence of recovery duration during 6-s sprint interval exercise on time spent at high rates of oxygen uptake
ConclusionIn conclusion, the duration of the recovery interval in 6-s SIE protocols appears to be a crucial parameter when sprint interval training is prescribed to enhance aerobic capacity. Further, the SIE15 protocol may represent a potential alternative to 30-s SIEWin in the development of time-efficient aerobic training intervention. (Source: Journal of Exercise Science and Fitness)

The effect of a 12-week combinational exercise program on CD4 count and mental health among HIV infected women: A randomized control trial
ConclusionExercise training can be included in health care services in order to improve the mental health status of women with HIV infection. No effect on CD4 count was detected. (Source: Journal of Exercise Science and Fitness)

Perceived physical literacy instrument for adolescents: A further validation of PPLI
ConclusionsThe PPLI thus appeared to be reliable and valid as a measure of the perceived physical literacy of adolescents. Thus, along with other validated instruments, protocols and research designs, the PPLI could be widely used to test adolescents' self-perception of physical literacy and their own physical and mental health conditions and thereby health. Physical education professionals may thus recommend appropriate intervention programmes for younger generations. (Source: Journal of Exercise Science and Fitness)

The relationship between ventilatory threshold and repeated-sprint ability in competitive male ice hockey players
ConclusionThe results of this study demonstrated that VT is substantially associated with RSA, and VT2 is more strongly correlated with RSA than V˙O2peak. This study suggests that longer duration high-intensity interval training at intensities that increase workrate at VT2 may lead to possible improvements in RSA.

The differences in physical activity levels in preschool children during free play recess and structured play recess
ConclusionProviding a physically-active recess period will contribute to preschool-aged children meeting the recommended PA guidelines; however, different children may respond in a different way based upon the structure of the recess period. (Source: Journal of Exercise Science and Fitness)

Quality of life in older adults: Benefits from the productive engagement in physical activity
Publication date: August 2018Source: Journal of Exercise Science & Fitness, Volume 16, Issue 2Author(s): Hsin-Yen Yen, Li-Jung LinAbstractProductive engagement can be a strategy to reduce stress and chaos. Physical activity, a basic type of productive activity, could benefit older adults. Therefore, the purpose of this study was to explore how productive engagement in physical activity may influence older adults in maintaining their health-related quality of life when they live in a long-term care facility. We used purposive sampling to recruit 163 participants from 14 long-term care facilities in Taiwan. Data were collect...

Influence of lateral pedal translation on muscle recruitment and kinematics in cyclists
ConclusionVL pedals may improve knee-to-ankle tracking through the pedal stroke and may allow cyclists to increase power output through the additional recruitment of hip abductors. (Source: Journal of Exercise Science and Fitness)

Functional movement screen comparison between the preparative period and competitive period in high school baseball players
ConclusionAlthough the low sensitivity and NPV and AUC scores indicated that the FMS does not accurately predict the risk of injury, the FMS individual task and total composite scores differed significantly between the PPP and CPP. Therefore, FMS could be used as a tool to identify physical deficiencies between distinct training seasons; however, utilizing the FMS as a screening tool for injury prediction in particular during the CPP in this population would not be recommended.
