Kinematic Comparison of Aquatic- and Land-Based Stationary Exercises in Overweight and Normal Weight Children.

Purpose: This study examined lower extremity kinematics in healthy weight (HW) and overweight (OW) children during water- and land-based stationary exercises (stationary running, frontal kick, and butt kick) at light submaximal intensity.

Methods: Participants included OW (N = 10; body fat percentage: 34.97 [8.

Stationary Exercise in Overweight and Normal Weight Children.

Purpose: This study examined differences in lower extremity kinematics and muscle activation patterns between normal weight (NW) and overweight (OW) children during stationary exercises (running in place, frontal kick, and butt kick) at submaximal intensity.

Methods: Healthy children (aged 10-13 y) were stratified into OW (n = 10; body fat percentage: 34.97 [8.

Lower extremity muscle function of front row rugby union scrummaging.

A rugby scrum's front row must act uniformly to transfer maximal horizontal force and improve performance. This study investigated the muscle activation patterns of lower extremity muscles in front row forwards during live and machine scrums at professional and amateur levels. Electromyography was collected bilaterally on vastus lateralis, rectus femoris and gastrocnemius muscles of 75 male rugby prop players during live and machine scrums.

Noise producing toys and the efficacy of product standard criteria to protect health and education outcomes.

An evaluation of 28 commercially available toys imported into New Zealand revealed that 21% of these toys do not meet the acoustic criteria in the ISO standard, ISO 8124-1:2009 Safety of Toys, adopted by Australia and New Zealand as AS/NZS ISO 8124.1:2010. While overall the 2010 standard provided a greater level of protection than the earlier 2002 standard, there was one high risk toy category where the 2002 standard provided greater protection.
