Study data for thesis: An exploration of muscle oxygen kinetics in professional boxing

Data associated with the PhD thesis 'An Exploration of Muscle Oxygen Kinetics in Professional Boxing '.

Study 1: In Study 1, the peripheral response of the rectus femoris muscle was investigated using NIRS wearable technology to determine the physiological demands of typical training modalities and a repeated sprint protocol in a sports science setting. 10 experienced professional boxers (age: 26±5 years, height: 177±4 cm, weight: 71±6 kg) on different days completed 6 x 3 minute rounds of pad, bag or spar-based training with 1 minute recovery time between each round, and on a separate occasion underwent lower body repeated Wingate trials, trials consisting of two, 30 second efforts against resistance (lower body 7.5%) with a 60 second active recovery. NIRS monitors where used to capture the physiological response, with data reported being time to both fast desaturation and fast resaturation and heart rate for all sessions.

Study 2:Examined mitochondrial rate changes following a three-week self-directed sprint protocol in nine male professional boxers. Nine male professional boxers (age: 26±5 years, height: 177±4 cm, weight: 71±6 kg) participated in a pre-post study design. The protocol included an occlusion protocol to assess mitochondrial rate changes and an incremental treadmill test to volitional exhaustion. Data reported the linear slope(SmO2 percent per second) of each of the occlusions for all three sessions, along the rate constant(k).

Study 3: This study Investigated the impact of heat on performance, recognising the common scenario where boxers transition from changing areas to competition areas with varying temperature conditions. Ten male professional boxers (age 27.22 ± 6.35, height, 175 ± 5.81 cm, weight 71.82 kg ± 5.12, body fat percentage 9.97 ± 2.72 kg) participated in a pre-post study design. The study consisted of participants undergoing repeated Wingate’s, 4 x 30 seconds with 60 second recovery, in both temperate conditions and hot conditions (35 degrees Celsius with 40 percent humidity), with data reported being sweat rates, haematocrit levels, time to both fast desaturation and fast resaturation, heart rate and wingate data such as peak, mean and average power.
