Liang Cheng, Shuwan Chang, Jingxian Li, Youlian Hong
This study investigated the effects of different periods of Tai Chi exercise on knee and ankle joint kinesthesia. A total of 20 Tai Chi practitioners and 19 controls completed the final test. Customized devices were used to measure the kinesthesia of the knee and ankle joints at the start, after 24 weeks and after 48 weeks of the intervention. Results showed that the 24-week Tai Chi intervention considerably improved the kinesthesia of the knee flexion and extension and ankle dorsiflexion. The 48-week Tai Chi intervention improved the kinesthesia towards knee flexion and extension, ankle dorsiflexion and plantar flexion...

Adrian W Midgley, Keith Earle, Lars R McNaughton, Jason C Siegler, Peter Clough, Fiona Earle
Fifty-nine men completed a VO2max test and a questionnaire to establish reasons for test termination, perceived exercise reserve (difference between actual test duration and the duration the individual perceived could have been achieved if continued until physical limitation), and perception of verbal encouragement. Participants gave between 1 and 11 factors as reasons for test termination, including leg fatigue, various perceptions of physical discomfort, safety concerns, and achievement of spontaneously set goals...

Graeme G Sorbie, Paul Darroch, Fergal M Grace, Yaodong Gu, Julien S Baker, Ukadike C Ugbolue
The study aimed to determine whether or not commercial golf gloves influence performance variables and forearm muscle activity during golf play. Fifteen golfers participated in the laboratory based study, each performing 8 golf swings with a Driver and 7-iron whilst wearing a glove and 8 without wearing the glove. Club head speed, ball speed and absolute carry distance performance variables were calculated. Surface electromyography was recorded from the flexor digitorum superficialis and extensor carpi radialis brevis on both forearm muscles...

Yu-Hsuan Kuo, Ching-Feng Cheng, Wei-Chieh Hsu, Del P Wong
This study's aim was to investigate the test-retest reliability of the 3-min all-out running test (3MRT) in hot environments. Twelve male sprinters (age 21.2 ± 1.8 years; height 1.78 ± 0.01 m; weight 71.0 ± 1.6 kg; [Formula: see text] 55.0 ± 1.0 mL kg(-1) min(-1)) performed an incremental exercise test in a laboratory, during which the first and second ventilatory thresholds (VT1 and VT2) and [Formula: see text] were determined. In addition, they performed two 3MRTs on an outdoor track in a hot environment, during which the critical velocity (CV) and anaerobic capacity (D') were estimated...

Pubertal growth in body size and functional capacities were examined in adolescent soccer players (n = 33). The average age at baseline was 10.9 (9.8-11.8 years). Peak height velocity (PHV) and growth curves for body mass and functional performance (countermovement jump, 15-m sprint, agility and Yo-Yo intermittent recovery test - level 1) were determined with Bayesian multilevel models. Estimates for PHV and age at PHV were 8.1 cm/year (95% credible interval: 4.2-18.5 cm/year) and 12.9 years (95% credible interval: 11...

The aim of this study is examining the effects of multiple sets of high-velocity resistance exercise (HVRE) on cardiovascular responses. Fifteen healthy adult men participated in two experimental sessions: one comprised three sets of resistance exercise performed against high-intensity resistance exercise (HIRE) at low velocity and the other three sets of HVRE performed against reduced load at high velocity. Blood pressure (BP), heart rate (HR), stroke volume (SV) and cardiac output (CO) during both sessions were evaluated using impedance electrocardiography...

Jochen D Schipke, Sinclair Cleveland, Markus Drees
About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. The sphenoid sinuses are rarely involved. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. Thus, barotrauma could lead to serious neurologic disorders, including blindness. After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge...

Ross Jones, Matt Greig
To investigate the anatomical distribution of linear and rotational forces during the tackle scenario, male rugby players performed a total of 48 trials, as ball carrier or tackler. Participants wore headgear accommodating three global positioning system units measuring uniaxial acceleration at the occipital region (OR), left tempero-parietal (LT-PR) and right tempero-parietal region (RT-PR). An additional unit was located at the cervico-thoracic spinal region in a custom vest. There was a significant main effect for tackle condition (P < 0...

This study examined the influence of fixture congestion on physical performance and biochemical variables in professional male footballers. After 3 competitive matches within a week (3M cycle), 16 players underwent blood sampling and field testing 72 h after the last match. The same tests were performed after a regular 1 match-week cycle (1M cycle). The 1M vs. 3M change scores were compared between Congested (high match exposure) and non-selected Control players. The change score in muscle soreness was greater (effect size 1...

Chronic ankle instability (CAI) is a common condition following ankle injury that is associated with compromised balance. Whole body vibration training (WBVT) programmes are linked with improved balance and function in athletic and non-athletic populations and may improve balance in CAI. Twelve healthy and seven CAI participants completed two randomly assigned interventions. Two Power Plate® platforms were attached back to back using a Theraband®. Participants stood on the active plate and inactive plate for WBVT and sham interventions, respectively...

The present study investigated the effects of a moderate-intensity soccer training session on the production of reactive oxygen species (ROS) and the antioxidant capacity in athletes along with the biomarkers creatine kinase and transaminases for lesions in muscle and liver cells. Twenty-two male soccer players participated in this study. Blood samples were collected 5 min before and after a moderate-intensity game simulation. The results showed a decrease in the concentration of reduced glutathione (GSH) from an elevation in the production of ROS that maintained the redox homeostasis...

This study compared the progression of muscular strength (MS) adaptation between age-matched Caucasian (CAUC) and South Asian (SOU) men during 6 weeks (3× week(-1)) of resistance training. MS was determined pre and post intervention by 3-repetition maximum (3RM) strength tests, and data were analysed using repeated measures ANOVA. Pre-intervention upper and lower body 3RM were similar between groups and both upper and lower body 3RM increased in CAUCs (P < .001) and SOUs (P < .001) following resistance training...

Claire Farquharson, Matt Greig
To investigate the efficacy of kinesiology taping in mediating the influence of fatigue on ankle sprain risk, 12 male soccer players completed single-leg dynamic balance trials pre- and post-exercise (soccer-specific protocol, isokinetic ankle inversion/eversion protocol) in each of three counter-balanced taping conditions (no tape, zinc oxide tape ZO, kinesiology tape KT). Balance was quantified as the overall stability index (OSI) and directional stability indices of platform deflection. Soccer-specific fatigue only increased OSI in the no tape condition (p = 0...

We present the case of a 16-year-old football linebacker with a history of recurrent stingers. Initial physical examination was normal as were cervical spine radiographs. MRI of the cervical spine revealed relative stenosis. Electrodiagnostic testing revealed chronic bilateral neurogenic changes of the superior trunk of the brachial plexus. A Kerr Collar was obtained to minimize head acceleration and force transmission through the neck. While there are return-to-play guidelines for recurrent stingers, there are inconsistencies with those recommendations...

Justin C Brown, Kathryn H Schmitz
In a post hoc analysis, we quantified the risk of musculoskeletal injury (MSI) associated with different volumes of aerobic exercise in a randomized trial. Premenopausal women (n = 119) were randomized to one of three groups: low-dose aerobic exercise (150 min·per week), high-dose aerobic exercise (300 min·per week) or control (usual activity) for 5 months. Compared to the control group, the risk of reporting an acute MSI increased with higher volumes of aerobic exercise, with a similar pattern observed for recurrent MSI...

Recommendations for physical activity and for fruit and vegetable intake are often not translated into action due to deficits in self-regulatory strategies. The present study examines the interplay of intention, intergoal facilitation, action and coping planning and self-regulation in facilitating physical activity and healthy nutrition. In an online study, intentions and behaviours were assessed at baseline, intergoal facilitation and planning at 4-week follow-up, self-regulation, physical activity and nutrition at 6-month follow-up in a non-clinical sample...

Backround: Nitrogen narcosis impairs cognitive function, a fact relevant during SCUBA-diving. Oxygen-enriched air (nitrox) became popular in recreational diving, while evidence of its advantages over air is limited. AIM: Compare effects of nitrox28 and air on two psychometric tests. METHODS: In this prospective, double-blind, open-water study, 108 advanced divers (38 females) were randomized to an air or a nitrox-group for a 60-min dive to 24 m salt water. Breathing gas effects on cognitive performance were assessed during the dive using a short- and long-term memory test and a number connection test...
