The Effect Of Barefoot Running On Emg Activity In The Gastrocnemius And Tibialis Anterior In Active College-Aged Females, Ryan Beierle, Phoebe Burton, Hayden Smith, Michael Smith, Stephen J. Ives

International Journal of Exercise Science

International Journal of Exercise Science 12(1): 1110-1120, 2019. Running is one of the most popular forms of exercise, thus overuse injuries such as plantar fasciitis, shin splints, and tibial stress fractures are also common. Barefoot/forefoot running has shown promise to reduce overuse injuries by decreasing the impact upon contact with the ground. The arch of the foot utilizes a ‘spring’ system that simultaneously reduces impact and propels the stride forward. Increased muscle activity in a particular location is indicative of greater impact forces, suggesting a larger risk for overuse injuries. The current study investigated the role of the barefoot condition …

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola Aug 2019

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola

International Journal of Aquatic Research and Education

Assessment of swimming and survival skills is a crucial part of any swimming and lifesaving programme. Unfortunately, quite often, it is also the weakest part of the programme itself. Inadequate skills assessment and verification might lead to ineffective skills acquisition and development, to a false sense of safety and over confidence in the water that can be extremely dangerous. Assessor experience and observation skills, assessment methodology, and criteria are all closely inter-linked and their interaction will somehow determine the assessment outcomes. Our paper analyses some of the current issues in these areas of the assessment process, such as assessor’s lack …
