Authors:F; John Pages: 89 - 97 Abstract: BACKGROUND: Pulse oximetry measures heart rate (HR) and percent oxygen saturation (SpO 2 ). For aerobic exercise, whereby cellular oxygen demand and delivery are elevated and maintained for extended periods, HR and SpO 2 values are consistent when measured by pulse oximetry. Yet due to its intermittent nature, HR and SpO 2 values from resistive exercise may exhibit lower data reliability and repeatability. OBJECTIVE: Assess intra-rater reliability and repeatability of pulse oximetry HR and SpO 2 values from two identical resistive PubDate: 2022-04-15T23:20:50-05:00 DOI: 10.3233/IES-200237 Issue No:Vol. 30, No. 2 (2022)

Pages: 99 - 107 Abstract: BACKGROUND: Bilateral strength asymmetry and fatigue predispose athletes to various injuries and conventional methods appear to be poor predictors of lower extremity muscular performance under NF conditions. OBJECTIVE: The purpose of the study was to compare the conventional Hcon/Qcon (HQR) ratio and the dynamic control ratio (DCR: Hecc/Qcon) under non-fatiguing (NF) and fatiguing (F) conditions and verify the effects of heavy-intensity constant running and cycling exercise on the isokinetic performance. METHODS: Twenty healthy male participants performed running and cycling VO 2 max at work-rate associated with the achievement of VO PubDate: 2022-04-15T23:20:50-05:00 DOI: 10.3233/IES-210105 Issue No:Vol. 30, No. 2 (2022)

Pages: 109 - 115 Abstract: BACKGROUND: Vibration training can affect strength improvement. However, the role of the vibration frequency, in terms of knee muscle strength, is unclear. OBJECTIVE: To evaluate the effect of vibration training with the same amplitude and different frequencies on the isokinetic muscle strength of the knee in juvenile football players. METHODS: Juvenile football players were divided into four groups: low frequency (n = 13, 25 Hz), medium frequency (n = 14, 40 Hz), high frequency (n = 14, 50 Hz), and control PubDate: 2022-04-15T23:20:50-05:00 DOI: 10.3233/IES-210177 Issue No:Vol. 30, No. 2 (2022)

Authors:Beyza; Fatma Pages: 117 - 126 Abstract: BACKGROUND: Some recovery strategies are needed to reduce or eliminate the effect of negative symptoms caused by exercise. OBJECTIVE: The aim of this study was to determine the effect of different types of recovery after single-bout strength exercises on biomarkers of muscle damage, cytokine release and lactate elimination. METHODS: Following familiarization, 10 male volunteers performed four randomized recovery protocols (passive or active recovery with or without compression garments) following a single bout of resistance exercise (squat and deadlift exercises).

Authors:S; Waleed Pages: 145 - 156 Abstract: BACKGROUND: Abnormal foot mechanics in foot over-pronation has an identified relationship with mechanical low back pain (MLBP). OBJECTIVE: To explore the use of short foot exercises (SFEs) as a standalone treatment for MLBP with foot over-pronation. METHODS: Forty-six patients with MLBP (PwMLBP) presenting with and foot over-pronation were analyzed. They were randomized into the SFE (short foot exercise), SFE plus traditional physical therapy treatment (SFE+ TPT), and control (CG) groups. Functional disability and pain level were measured using the Oswestry Disability Index (ODI) and visual analog scale (VAS), respectively.

Pages: 1 - 10 Abstract: BACKGROUND: Lumbar radiological abnormalities (LRA) and trunk muscle weakness are major causes of the low back pain (LBP). We reported that the prevalence of LRA was approximately 90% in middle- and heavyweight-judokas, independent to the occurrence of LBP. However, the trunk muscle weakness, especially the rotators, plays a key role in occurrence of LBP in heavyweight judokas. OBJECTIVE: To examine the trunk muscle strength (TMS) and LRA impact on LBP occurrence in lightweight judokas. METHOD: The strength of the trunk extensors, flexors, and rotators was measured in 32 lightweight male judokas.
